A2017 4th category brick repair manual (when ZTE ... ... Interface DFU mode ony) - ZTE Axon 7 Guides, News, & Discussion

Hi folks!
I have great news for those of you who have bricked your devices completely and you don't have any possibility to apply this as a warranty case. By this I mean that your Axon 7 is not booting to system or any other possible modes except the DFU mode which detects by PC (Device Manager) as ZTE Handset Diagnostic Interface(DFU) (COM...). And neither any of the software tools nore Deep Flash cable didn't manage to help to unbrick it.
There is a solution! Please pay precise attention to each step and make sure that you are capabale of doing all the actions otherwise refer to a professionals to do the job!
Axon 7 restore manual from bricked conditions when only ZTE Handset Diagnostic Interface(DFU) (COM...) mode is detected
All actions you do at your own risk. If you are not sure that you can do it by yourself then refer to a professional!
Method description:
Device repair is performed with MiFlash tool with forcing the phone into EDL mode. To do that you will need to disassemble the phone and circuit the TEST-POINT. After that Windows Device Manager will detect your phone as Qualcomm HS-USB QDLoader 9008 (COM...).
Terms and Definitions:
Repair package – folder on PC that contains all necessary files to flash the phone with MiFlash tool in EDL mode.
4th category brick – phone status which does not allow to boot into next modes: Recovery, Fastboot, FTM, EDL. In Windows Device Manager the phone detects as ZTE Handset Diagnostic Interface(DFU) (COM...) whrn you connect it via USB cable. Any of possible manupulations give the same DFU mode (even when you force to install Qualcomm HS-USB QDLoader 9008, in reality it is still a DFU mode).
ATTENTION!!!
Considering that this method requires the phone dassasembling, please pay your attention to the teardown video and evaluate your capabilities of doing that. The build quality is good enough, so it will be quite a challenge to dissasemble it without parts damage, if you don't have experience and tools. The best way to do it is to give the phone to a specialit (preferable trusted one) along with this manual.
Special thanks to:
Stas13071992 - the first ever person who have found the TEST-point (critical spot for flashing).
djkuz - the guy who have helped to find this solution, created this manual and already helped to repair a bunch of bricks distantly.
brenic - guy who have collected required files to create Repair package.

And then...
Major actions after body dismantle:
1. Disconnect ribbon cable of the finger print scanner.

}
2. Remove the screw with the silver bracket covering the extension ribbon cable.
3. Unclip all indicated connectors with plastic tool. Notice! The extension ribbon cable marked with green arrow (Main – going from type-c board to motherboard) has to be connected back during flashing!
4. Unscrew four screws of the motherboard.
5. Gently lift off the motherboard (it is held/glued with the thermal grease of the processor).
6. Detach signal antenna wire from the right side of the motherboard.
7. Unsnap the rear facing camera.
8. Here you go, the Test-point (marked with red arrow)! (do not forget to connect the extension ribbon cable back (going from type-c board to motherboard).
Repair process
First download Repair package with B13 firmware, Android 6.0 (for China models) A2017_B13_FULL_EDL_UNBRICK_DFU (mirror on yandex.disk). Unpack all the files to separate folder.
Second download and install Qualcomm drivers and MiFlash.
MiFlash manual.
1. Connect original USB Type-C cable to the phone.
2. Circtuit Test-point on the housing (there is sim-cards slot body nearby).
3. Connect USB cable to PC USB-port (preferably USB 2.0 version).
4. You will hear the USB device connection sound from PC (but you will not notice any vibration of the phone or red diode indicator blinking).
5. Make sure that Windows Device Manager have detected the phone as Qualcomm HS-USB QDLoader 9008 (on COM port). If it is not so or if it has detected an unknown device then make sure that you have installed Qualcomm drivers (even forced installation if required). You can release Test-point at this moment. Then disconnect USB cable from PC USB-port.
Repeat the procedure of Test-point circuiting on the housing to make sure that PC detects the phone as Qualcomm HS-USB QDLoader 9008 (COM...) in the Device Manager.
6. Circtuit Test-point on the housing again and hold it (do not release or brake this circuit)!
7. Run MiFlash on your PC, then specify the path to the firmware folder and push "Refresh" button. You should see the device detected in the program window.
8. Then push "Flash" button and the flashing process will begin. NOTICE: you should hold the Test-point cuircited until you see the sign "send configure command", then you can release Test-point circuit.
9. After flashing is completed you should re-assemble everything back and turn the device on.
10. If the device is turning on successfully then don’t forget to go to recovery mode and perform "Factory Reset" (because in userdata there can be some garbage that left from Android 7.1.1, it can interfere successful load to the system).
Here you can download this whole manual in English in MS Word format.
I'm sorry that some of the links are in Russian language since the content is located on 4PDA.ru forum. You can use translate.google.com to understand how to access the files. Or you can find the files with drivers and MiFlash somewhere else.
Good luck and be carefull with your devices!
Status: tested and works!!!

Thanks, I'm sure it'll help some people, but performing this when your phone has a software problem and you still have 3 years left of warranty seems a little crazy to me.

Good point, but it mostly concerns chinese models when you buy the phone with no warranty.
Moreover, if you bricked you phone it is likely not a guarantee case.

Anyone define what "Circtuit" means?

If the phone is completely bricked how can they prove it was your fault?

I think by default you can't brick the phone with locked bootloader, on the other hand if you have bricked the phone, you have unblocked bootloader. And this is not a guarantee case.
In reality, I know that Chinese shops from AliExpress will not even bother with any kind of investigation. As minimum they will replace motherboard, as maximum replace the phone, but they will charge some fee in any case.

Okay, all doable, except this part. I have an A2017G. Does anyone know what the package consists of, i.e. what we have to flash instead? Is there any package for G, or does anyone know about a way to do it on non-chinese?

I would say all the above except you'd use a European rom, specifically for the A2017G.
It should work if all the hardware is the same...

I got to the send configure command but it's failing every time... i'm keeping the pin held there

Done! It's the most finicky process I ever made, what with the tiny copper contact and MiFlash flashing stuff only when it's on the mood. After around 30 tries and a successful flash of a zip I didn't have to flash, I managed to get to the configure command thing and left the short circuit there for 3 seconds more. after that it started flashing and I almost shat myself

Yeah, perfectly fine as of now. I noticed that the bootloader was not unlocked when on B10 (no The software can't be checked for corruption message) but it got unlocked after updating to official 7.1.1 B01 for some reason.

This message did not appear because in my B10 package I replaced aboot (used from the USA version of the phone B20). When installing firmware B01 7.1.1 aboot changes to the original and the message appears again!

So I'm trying to do this with my A2017g, but it only stay in com for like 3 seconds, then it's gone. I don't have the time to flash anything...

I swear to god, if this work, I'm staying stock forever.

Okay, now this is annoying. is the EDL mode supposed to last 2 seconde, is there something really wrong with my phone ??? I don't have the time to flash anything before it dissapear ! I can't reach the "configure command" step...

i had the same issue like you when i tried to mod Bruno Martins's Extended User Data to my A789...
Then i think to myself how did lenovo flash in ROM at the first place & with that google leads me to this post about Power On sequences, thank you so much Master Shifu.... :good:
However, i can't exactly recall which or the correct sequence as i was trying all combinations with Flash Tool set at download mode all the time & voila, suddenly Flash Tool starts to download & i got my A789 back...

Ohh realy you gave me new hope because its completely dead like no power on no charging tried all posible combinations
but now i have to try all seq in download mode but the issue is A660 factory not out yet i search so many chineas forms.
But atleast if it detects then there is some hope. I alredy packed to send back to china but i will try and tell you please pray for me and if you remember key sequence please write here thanks for giving me hope

if not mistaken, its the Vol-Dn + Power goes into META mode... :fingers-crossed:
my best guess is the preloader as cybermaus has mention, for my case i use A789 preloader at first for my modding & internal memory just increase 100MB then i download the V970's preloader_mt6577_phone.bin which i though was generic then ends up problem just like you... It actually doesn't detect the phone but with the right combinations of Power on sequences it accepts Flash Tool download...
But first did you do a full ROM backup ?
Your case is a completely different than mine so i guess we'll have to wait for Master Shifu cybermaus to further advice you since you don't have a full factory ROM... :fingers-crossed:
Good Luck... :fingers-crossed:

@yuweng; @adeelahmed11
Yes, META mode is to flash without preloader. With it you can format the entire eMMC chip, just like we used to do on our MT6516 first generation of Mediatek Android chips. And indeed, it is how the factory puts on the preloader in the first place.
However, I was under the assumtion the following 3 issues would make this hard to use for adeelahmed11:
- The meta mode does not use USB, but bootstrap using serial, and requires a special cable in the 3.5mm audio port.
- On the A660 phone PowerDown+Volume down goes into FACTORY mode, so META mode must be a different one, but he has no more buttons to try.
- He would still need a factory original flash package to flash onto the A660
Now, if what yuweng said is true, and he really broke his preloader, and fixed it without special cable, then I would have to assume somehow Mediatek worked around the serial cable requirement. Maybe they integrate the PL2303 USB to Serial hardware in the chipset. That would be sweet. Or maybe they can drive the USB without preloader software in some rudimentary mode.
Tell us yeweng: Did you ever put a PL2303 device driver on your PC? Also, did you put the flash program in serial mode instead of USB mode (it's an option in the flash program menu.
As to adeelahmed11, if you want to try this, it may be better to first wait for a real A660 ROM. If somehow you get the phone into META mode, and the flash utility starts to flash, you want it to flash the right stuff. If you overwrite it with more wrong stuff using this deeper level, well, it will not improve matters

Wow, now that you mention so many stuff here in fact (1) i did have PL2303 USB driver that i use at work for serial downloading software but that usb to serial converter was not plug in to the pc. It didn't show up as active device at device manager...OS Win7 x86, i've attach the report generated by USBDeview...
(2) i use android-sdk usb_driver as the mediatek preloader driver doesn't work on my pc...(3) can't recall which version of Flash Tool i use for downloading, either version 3.1224.01 or 3.1222.00
(4) i did tried disable/ enable USB Mode at Flash Tool but can clearly recall it was in USB Mode when it starts to downloading...
(5) i was using only five files PRELOADER, DSP_PL, MBR, EBR1 & RECOVERY during my modding & first, i use all files from A789 with modded scatter.txt. As said, the mod wouldn't work & i started to use each file one by one from V970 & my last try was the preloader that got it 'brick'...
(6) For my case it was full ROM download but i presume download with the correct preloader would have 'unbrick' it...
Mostly said Mediatek is 'unbrickable' so lets hope we'll be able to 'unbrick' adeelahmed11 A660... :fingers-crossed:

You kept a USB sniffer active while you were messing with your phone? Or is this a USB sniffer-log of a different time?
If the first, then I take of my hat to you for foresight! If the latter, then I am not sure if I want to spent time analyzing it. So please do tell me which. Edit, its not a stiffer-log, just a list of installed devices. How do you know it was not active during your rescue?
Reading your story, it is less encouraging: You tried Druno's repartitioning, so that scatter file would have messed with the MBR and maybe EBR partitions. And while you did reprogram the preloader, you did so from the original phone? I can imagine that if you break your MBR, the phone would appear to be very bricked, but not as deeply as when the preloader itself is broken. I am thinking your preloader, and therefore your USB client-side software, was always OK.
A further hint would be: Did you have to reprogram your IMEI number and/or WiFi/Bluetooth MAC addresses? If not that is a further hint your phone was not truly bricked.
As a reference: The way I see the preloader is as the BIOS of the phone. It initializes some core hardware, so the actual boot, the uboot, can kick off. But first, it initializes the USB port, and has some bytes of software so that the USB port can be used to communicate and reflash. It waits a second in this state, before really kicking off the uboot The way I see META mode is as a sort of JTAG interface, so that with no software at all on the phone, through a simple serial port, you can very slowly program the flash chip from scratch.
Of course. that is what I suspect, and we have learned to distrust my suspicions.

Thank you Master Shifu for sharing your insight... :good: USBDeview is what i use for trouble-shooting for my usb to serial converter & the log was taken after the 'unbricking' process...Whoops, i can't confirm what was active during the rescue but i can confirm nothing shows up at device manager before the download starts & i didn't check what is there at device manager during the download...
i actually did the modding with caution but never thought wrong preloader would 'brick' the phone.... I've compare both files from A789 & V970 & to my surprise it is the same bit for bit except for PRELOADER & EBR1...even the scatter file is the same except for __NODL_FAT 0x629e8000 ! Bruno's Extended Data mod doesn't download everything... Fyi, i actually use scatter from Lewa ROM & earlier i have ported bruno's V970 to A789 with no patching at all, everything works except WiFi, GPS & a few others... Even after patching firmware folder with few related *.so, the problem remain the same... Well, i guess V970 is for V970 after all but it is very similar to A789 system files... :laugh:
So i guess for adeelahmed11 case, he has to get the correct preloader file to 'unbrick' it...

Other useful tuts from russia here & here... :good:

Yes, that Russian site you found is the *normal* thinking that I also have/had. You need a USB-to-serial cable, and you need to connect the cable to a serial port. For a lucky few, the serial connection is hidden in the 3.5mm port, but that may not be on every brand and model. You notice how that guy is happy he found a point on the board that is the serial connection? You can bet he tried the 3.5mm first. Next he went to look on the circuitboard itself. It what I would have tried, if I had a brick in my hands. But unless if you have the tools and skills, it is not for the normal user.
You however claimed you did it *without* serial cable, *without* serial port, *without* 3.5mm connector. That is what surprised me. Either you did not really brick your preloader. Or Mediatek build in the USB2Serial module into the later chips, in which case that Russian link you found is nice, but on the too difficult and thus unneeded track that I would have gone also.
If true, the trick must be in the fact you had the PL2303 driver installed. When cold-staring your Android, the phone briefly linked up its PL2303 mode with the driver. And you had your flash tool set to serial. So it simply worked. If I recall correctly, a button combination may not even be needed, if you have the PL2303 driver active the flash tool will simply send a command over it to go into the programming mode automatically. Or at least, it did so for the MT6516 chip, as described here.
But for now, lets simply wait until a A660 ROM turns up. Or someone else with a brick in his hands and a matching flashable ROM to go with it.

Thank you so much for creating the thread and your help, i tried all possible key combinations, but there is no last breath i think i should not waste time and try to claim the warranty because its almost a week old, so better chance to get back, i can try the usb to serial but i need the cable and its not available in my city and if i order from web it takes time, also still A660 Rom not available, etotalk.com claiming that they have rooted rom but they are not selling it , they are selling with phone only.
if i get back a new phone i will try the flash again but without selecting the lo level files like MBR and preloader
anyway thanks guys

My dear Master Shifu cybermaus,
Just as you suspected, indeed, it become serial port...
i don't have to press the power button, with the battery out, i just hold the volume up on my A789 while plugging in the USB cable will activate META mode... :laugh:

I'll watch the video later.
Also, I see that a ROM has surfaced: A660_S019_120824
I will download it if I have a change, and try to create a recovery / ROW ROM for it

What video boss and did you found the a660 rom so then i can try vol + and plug the cable

Ah, so you still have it then? Warranty not accepted? Bad for you, but strictly speaking correct, the shop did not send you a faulty product.
The ROM is this one with password bbs.lenovomobile.com
Do try to see if you can get it to work, by setting the flash tool to serial (not-USB), but to be honest, I still have my doubts about yuweng's case. I still wonder if his preloader was truly bricked. The video above shows the serial as it is provided from the preloader.
I did a full USB sniff/trace on the bootup process. In it, I did see above COM port, but not one before that.
But if he is correct, then the procedure will most likely be to remove the battery, connect the cable, start the download in the flash program and insert the battery.
You can also then try any button pressing, like power+volume-up to go into META mode. But this is I suspect controlled by the preloader, so that must be working. We need something before that phase.

Need CMW Recovery for Tooky(T1982) MT6575
Hi,
I tried this Rom with pressing vol+ while connecting to PC but nothing happened any way i sent back to china.
now i need help in my other china phone which is Tooky T1982. it is MT6575 so i tried Lenovo A750 Recovery but its not working, can you compile for me ? or guide me how do i it my self ?
here is i uploaded for your reference Tooky T1982 Rooted Rom
My 2nd question there is another model of Tooky T1981 and it has ICS 4.0 Rom can i port it to my Tooky T1982
here is i uploaded for your reference Tooky T1981 Rom
Waiting for your positive reply

i refuse to believe Lenovo has taken out META mode feature on newer device...
Have you tried all other combinations...
At Device Manager -> Ports, there should be MediaTek USB VCOM(Android) ComXX or at least an unknown device should pop-up with the usual device connect sound if you have ur speaker switch on...
Refer to my video, however, for your case, the PRELOADER shouldn't have shown up since i capture it when i have already 'unbrick' it & i don't dare try to 'brick' it again to have the video capture again... :laugh:

I tried all possible key combinations but no device detected but i have also ZTE V970(not bricked ) so i power off the device and while press the VOL+ button plug the usb cable and PC detect some APEX device under windows 7 but Vcom drivers did not apply on it

Ok ok, one last try if still cannot then no choice you have to sent it back... :fingers-crossed:
From my experience with 2 types of MT6577 as follows :
With battery inserted
Switch on ur speaker so that you will know if there is a new device connected (the sound is exactly just as u plug in ur USB thumbdrive)
1) Hold Volume Up, don't let go, now plugin USB cable ( this doesn't work on ur A660 )
2) Hold Volume Down, don't let go, now plugin USB cable
3) Hold both Volume Up & Power, don't let go, now plugin USB cable
4) Hold both Volume Down & Power, don't let go, now plugin USB cable
or may be u wanna try the unlisted method...
1) Hold both Volume Up & Down, don't let go, now plugin USB cable
2) Hold all button (Volume Up/Down with Power), don't let go, now plugin USB cable
With battery taken out
Same as above methods but with battery taken out
You have to have SP Flash Tool set to Download mode all the time while trying above steps & see if it starts to download if not then only try next method...May be u would also wanna try different USB port too if ur mobo supports USB2.0 or 3.0
I've also experience before with the battery taken out method, it may fail half way...What i did was, when it starts, reinsert back the battery & SP Flash Tool went on all the way ( this method i did was uploading system.img )
If it doesn't detect as Mediatek VCOM then fast fast double click it at Device Manager & force update it to Mediatek driver...

That may be less easy than you think. Firstly, trat 1982 phone seems to not have hardly any hardware buttons. So you would need the Touch version of the recovery. But with a different resolution the Touch version that I have may not work. I will attempt, but I cannot give any guarantees.
For the same reason porting 1981 to 1982 is difficult. Different hardware buttons. Would be interesting to do if I had both phones in my hand, but as a blind build it is too error prone.

At Device Manager -> Ports, there should be MediaTek USB VCOM(Android) ComXX or at least an unknown device should pop-up with the usual device connect sound if you have ur speaker switch on...
Refer to my video, however, for your case, the PRELOADER shouldn't have shown up since i capture it when i have already 'unbrick' it & i don't dare try to 'brick' it again to have the video capture again... :laugh:

[Q] Zhou Xing - How do I get the files to flash with SP Flash tool from stock ROM?

[update 2013/04/10]
And it is back to life! :victory:
I still cannot believe it! I decided to have another go using the Haier W718 USB cable and guess what? The cable supplied with the Zhou Xing i9300 is basically a big piece of s****.
I can confirm that the test point which worked for me are also GND + KCOL0
I have flashed the ROM wich link yuweng supplied. Thanks, again, bro :good:
Most things work except:
1) The ribbon cable running from the volume keys to the upper board is detached and I am not sure of how to fix this. Is it crazy to "superglue" it?
2) The IMEIs are not recognised. I have tried setting them up manually (following a video from Colonel Zap and taking the digits printed underneath the battery slot). No joy, no matter what SIM card slot I try, I get "IMEI invalid". In engineer mode, under bandmode, I have actually noticed that no band is selected. I check those applicable in Spain and click on "Set", but it basically ignores it.
So I am trying to get now a new ROM, hopefully closer to our settings in Spain. I have contacted a fellow member from a Spanish forum. Fingers crossed.
Oh, I almost forgot. Since the volume keys are not working because of the detached ribbon cable, I have ported TWRP recovery for the Zhou Xing. I thought a touch screen recovery would come in particularly handy now! Here it is.
BACKGROUND STORY BELOW:
Hi all!
I softbricked my Zhou Xing i9300 (MT6577) and now it won't boot :silly:. I cannot even get into recovery mode.
The only way I can access the phone is by SP Flash Tool. Thanks to another member of this forum (Dragonevo) I got hold of the stock ROM. However, this file is in a zip format, so the kind I have seen updating from recovery mode. Only the boot.img file is found out of all the files SP Flash tool looks for. Is there a way I can get the rest of the files for SP Flash Tool from this stock ROM zip including the scatter text?
Thanks!

At first I still got it recognised as MTK device, but right now the best I get is an "Unknown device" under USB devices (not under COM ports). This is with the phone completely assembled and battery inserted. When I dismantle the phone to try to trigger test point, no sign of life whatsoever. If I try to update the drivers, I get something like "Windows determined the best drivers are already present". I guess Windows is only detecting the device as some kind of USB memory and that is it.

I already found a ROM thanks to dragonevo's pointer here. The problem is, I guess, this ROM is in a format to be used when you can boot into Recovery mode. I say "I guess" because I have never got to see Recovery mode on this phone. I am not even sure of the key combination (tried Power & Volume + and Power & Volume -). I am using SP Flash Tool and it looks first for a scatter text file, and several other files that are not in that ROM zip, (only the boot.img is there). And from what I gather all these files also are specific to the phone model.
This is why I raised my original question in this post, so that I could use the ROM found in Flash Tool.

2.9 v (I have a spare one which reading is 4.1 v)
Reminder: when I try the test point, the battery is not present (it cannot be since the board has to be completely dismantled on this phone to access KCOL and GND points. commonwarrior has another phone model but exactly the same board and it has worked for him this way. If I got this right, the battery is not required and Flash Tool (since yesterday I am using the latest supplied by commonwarrior) actually has an option called "Autodetect", which is supposed to work either way, with and without battery). file is in a zip format, so the kind I have seen updating from recovery mode. Only the boot.img file is found out of all the files SP Flash tool looks for. Is there a way I can get the rest of the files for SP Flash Tool from this stock ROM zip including the scatter text?
Thanks!
[update 2013/02/14]
Sorry about vanishing, guys. I actually bumped into a bigger problem. My PC hard disk crashed. Anyway, I recovered my older (and smaller capacity) hard disk and installed it. As to the OS, I have just installed Ubuntu 12.04 + Windows XP as a virtual machine. I am a novice to Ubuntu, so please forgive me if the ending of this story is still delayed as I have other priorities to take care of right now.
Thanks a bunch again to yuweng for the correction for the test point and finally the files to flash from SP Flash Tools. I have downloaded the files and will have another go when I get the chance.
To be continued...
[update 2013/02/18]
I am afraid I am giving up on the Zhou Xing. No matter what test point I try, I never get any response in Flash Tool (I have also tried different versions including the latest one uploaded by commonwarrior).
With all the handling, the flat small cable that runs from the Volume up and down keys is detached from the contacts on the main board and I cannot see how I could weld these back.
So I am closing this chapter on my end. I hope it has been helpful to other people. At least now we have the files to flash from Flash Tools for this phone model. I wish we had found them before I screwed it completely.
Thanks again for all your help, particularly to yuweng and commonwarrior

Sorry, pigu36, I actually never got into Recovery mode. I flashed mine (and softbricked it) with SP Flash Tool.
Regarding the stock ROM, you will find the link in Dragonevo's post.
Maybe in that same thread, somebody will be able to tell you how to get into Recovery mode. As far as I am concerned, I have tried pressing "Power + Volume up" keys, but it has never worked.
Whatever I find out, I will share it here and in the other thread.
Good luck!

so whats the issue of playing with test points if u can make it detect thorugh spf ?

Sorry about the confusion, khankll.
This was before I tried to flash something else because I thought it could not get worse and maybe I could flash some kind of Recovery which would allow me to update from the SD card (where I have a copy of the stock ROM in a zip file).
However... things could get worse and they did. The phone is not detected any more even in SP Flash Tool, not charging... well you know the symptoms. So I found the test point thread and fingers crossed with all the advice you guys are helping with
If I am lucky with the test point method, I will still need the type of files SP Flash Tool looks for. Unless you know a way of getting them (converting repacking, I don't know what the right word would be) from the stock ROM zip file.

Good news, found your Stock ROM here, credits to Анатолий... :laugh:
it turns out the testpoint KCOL0 & GND is wrong, credits to orx65...
Hopefully, this infos here will be useful for Zhou Xing users to unbrick their device too... :fingers-crossed:

Many, many, thanks for this rare rom. So I was able to unbrick my phone without any hardware experiments. I searched several Weeks!
My only problem is, that there is no touchscreen-response.
Any Idea to solve this problem?
Thanks and regards
Herby53

Hmmm, could i be that you forgot to install back the Touch Screen panel Flex Ribbon Cable...
Attach example is my friend's Touch Diamond2 9300 i help him replace the Touch Screen panel, hopefully it will be useful as a guide...
Another possibility is that may be this ROM is not for your Zhou Xing... :laugh:
Could you comfirm that the testpoint for your Zhou Xing is KCOL0 & DM

Thanks for the fast response, Yuweng
I have installed back the Ribbon Cable, but not correct and without complete contacts. Now the TouchScreen works, but the touches lands not there where they should. Especially noticeable when using the phone keypad #1-3 = #4-6. I think I have to calibrate the touchscreen, but don't know how.
Second problem: the hardware- (volume up / down) - and sensor buttons (menu, home and back) are without function. I hope I did not damaged the flat cable searching the testpoint.
Your question about the testpoint:
See thread ..... / / forum.xda-developers.com/showthread.php? p = 36908056
# 240
The first image shows the backsite of the board. Testpoint for me wars KCOLO & GND to start flashtool download => there is no Point DM.
Greetings
Herby

Hmm, according to orx65 photo on previous page, its definitely not KCOL0 & GND ( the two red dots )....
Big problem ! To calibrate Touch Screen, you need to boot into Factory mode....
Shut down the phone then hold Volume Down, don't let go & press power button until you see that it boots into Factory mode then only let go... :fingers-crossed:
Then it will display all the keys that you need to press once then only you can proceed with the Factory mode calibration...
ESC, BACK, MENU, VOLUME UP, VOLUME DOWN, POWER

Thanks once more!
I first have to repair the definitly broken flat cable for the hardware buttons. It already looked a bit cracked out of delivery.
But my fingers and my soldering iron are to big. :laugh: I must look even if there's a trick!?
Testpoint:
The combination on first picture (with phone 9 ContactPoints) ist KCOLO (2nd row/ center) & GND (first row/ center) worked for me.
It's shown in the picture thereunder.
There is no Contact with DM. 3rd Row right Contact is named DP, but I don't know if this ist what you are looking for.

There is one crazy idea on repairing the Flex Ribbon Cable here with a staple... :laugh:
Can't see it clearly on those photos, so what i meant was : does KCOL0 with DP works, if not then i'll remove the photo on previous page...

... for me only KCOLO & GND works ...

Hey! You don't have ti flash it under a virtual machine. It causes problems. 1st of all, you have to download the stok rom, unpack.it on a pc with a windows installed. Install the.phone.drivers. disassembly the.phone and do a little.test point.to recognize the.flash mode. Run the.flash tool.loading the scatter file of.your stok, start the flashing in all the ports using the Automatic flag in battery section, the Preloader flag under the battery section. Also check.the usb option, just enable.the.Usb and not mpre.connetions kind. Start the flashing.in alk the ports, make.a.little test point and you.will see the loading.flashing.bar sorry for the errors in my typing.thw qwerty touch is very hard to use

[GUIDE][FIX][DISCUSSION] LG G3 Hard Brick Recovery

UPDATE: I have updated this post with a file named "board diag v2.99.zip" This should now support more phones!!!
Several people have been having issues with hard bricks and there are several posts with a bit of info about how to fix them but no simple instructions so I'm posting a (hopefully) fool proof guide to fixing your hard brick. Tested on windows 7 and windows 10.
First what is a hard brick? A hard brick is a phone that does not boot, or is stuck in a boot loop, or has a security error AND cannot access recovery or download mode.
Disclaimer: Your warranty is now void etc. I am not responsible etc. You have to open your phone to do this so it is a last resort. Read the entire tutorial before beginning!
Required Materials:
Bricked LG G3
Stock USB cable <-- or at least one that you know is good
a short thin but stiff wire to short pins
Qualcomm high speed usb drivers
BoardDiag by willcracker <-- other versions don't seem to work
The tot file of the rom that you were running. (not older not newer same version) You can find these easily on XDA or google but it varies depending on your software version
First you need to install the Qualcomm high speed usb drivers. Your phone will be detected as Qualcomm 9008 (COM) later on in the tutorial but you need these drivers. I will include the drivers in this post. If you are on a 64 bit system you will need to disable driver signing. Here is how:
Step 1. Open the Windows command prompt as “Run as Administrator”.
Step 2. Run
Code:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
Step 3. To finalize the process run
Code:
bcdedit -set TESTSIGNING ON
Step 4. Reboot and you’re done.
I have attached both the 32 bit version and the 64 bit version be sure to only use the 64bit one on 64bit and likewise only use the 32bit one on 32bit, you do not need both sets of drivers.
1. Open your phone and take out the battery. Remove the top half of the phone housing. You do not need to remove the bottom half by the usb. Also you don't need to remove the screw next to the camera. If you do remember that it is a different size so keep it separate.
2, You will see a big metal shield. You need to remove it. It is pretty easy just pry it off and it pops back into place when you are done.
3. Next you need to short the pins as shown in the following picture. While continuing to short the pins plug in your usb cable. You should hear windows detect the phone almost instantly. Keep shorting the pins for the count to 5 and then you can release the wire. See image below, ignore the ethernet connector.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4. Now open device manager in windows and it should show your phone under com ports as Qualcomm 9008 (COM #). If it doesn't try the process over again. When it does work remember this number. It is going to be used later.
5. Now fire up BoardDiag by willcracker be sure to run it as administrator. It is in this post named willcracker.rar There are some pictures on how to flash with this app but I will describe it as well. First we are going to need to extract your tot file. This can take some time. Like 10 mintues on a decent PC. The app may look like it froze up but it is just thinking. When it is complete move on to the next step.
6. You need to tell the program the com port that you are using that we found earlier and the folder where you extracted the firmware to.
7. once you have extracted the firmware and set up the program with the correct port you need to Check "AP" and "EMMC" then press start. Be sure not to select any partitions or change any other options than the firmware directory and comport.
It should come back as PASS. If it throws an error about not being in dload mode you need to restart the shorting process. Hold the short for a bit longer this time.
8. Flash all of the partitions except for Cache, System, Userdata, and Sbl1. Sbl1 will be flashed later and causes the phone to reboot.
You can flash System, Userdata, and cache but it takes a really long time so I don't recommend it. It is better to get your phone into download mode and use LG flash tool to do a full restore.
9. Once you have finished flashing all of the partitions one after the other put in the battery and flash Sbl1. Your phone will now reboot and try to boot into android. If your system is messed up it wont. You will still be in a boot loop. But you should now be able to enter download mode and recovery.
10. Open up LG Flash Tool and flash your tot using Board DL mode. Everything you need at this point is in the following thread http://forum.xda-developers.com/spr...de-how-to-restore-sprint-lg-g3-ls990-t2852042
Hope that this helps, also if you find any problems or need help please post so I can update this post.
NOTES: If you get an error about a dll missing you need to download and install the following http://www.microsoft.com/en-us/download/details.aspx?id=5555
Also make sure that you use "B2 (MSM8974AC)" as the AP Chipset for the LG G3.

I assume that you are using sprint ls990 if so here is are the latest tot files. ZV8 and ZV6 can be found here http://downloads.codefi.re/autoprime/LG/LG_G3/LS990 thank autoprime. The files are zipped just extract the zip and then do the process above.
ZV4 can be found here direct link. http://downloads.codefi.re/wolfgart/LG_G3/LS990/ZV4/LS990ZV4_04.51101.zip

Any chance this works on ATT D850?

For myself and the benefit of others, I'm just clarifying something. I've always understood there to be the "hard brick" and the "soft brick". The soft brick is what you describe above where your phone lights up but doesn't boot. A hard brick is where nothing lights up, and your phone doesn't respond at all.
If someone were to describe what you describe above, I'd say that's not a hard brick. There's hope for a soft brick but not a hard brick. Am I wrong, or have the terms morphed a bit in the past several years?

I was always told that a soft brick could be repaired with either recovery or fastboot and that a hard brick was anything that you needed more tools to fix. But I guess that everyone's definition is different. Also This method works on any kind of brick as long as there isn't a hardware issue. No screen on, no power on etc.

Sorry that I missed your post.... but yes this should work on all variations of the LG G3 as long as it has the points on the motherboard posted in the picture. I do know that the international dual sim version has different pins and I don't know those pins but ATT, Sprint, Verizon, should all work.

I think i need to create a file under model like B2 (MSM8974AC) with 2nd_loader.hex etc. Can you help me on this or is it unnecessary ?
currently i get the error
No response from the device. Check PMIC first and if still boot problem, replace AP

You are right about not needing to short the wire and also about needing the correct 2nd_loader.hex etc. However I don't know how to make those. Attached are some more models that I found online. Hope that this helps.

Step 1. Open the Windows command promt as “Run as Administrator”.
Step 2. Run
Code:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
Step 3. To finalize the process run
Code:
bcdedit -set TESTSIGNING ON
Step 4. Reboot and you’re done.
I have attached both the 32 bit version and the 64 bit version be sure to only use the 64bit one on 64bit and likewise only use the 32bit one on 32bit, you do not need both sets of drivers.
1. Open your phone and take out the battery. Remove the top half of the phone housing. You do not need to remove the bottom half by the usb. Also you don't need to remove the screw next to the camera. If you do remember that it is a different size so keep it separate.
2, You will see a big metal shield. You need to remove it. It is pretty easy just pry it off and it pops back into place when you are done.
3. Next you need to short the pins as shown in the following picture. While continuing to short the pins plug in your usb cable. You should hear windows detect the phone almost instantly. Keep shorting the pins for the count to 5 and then you can release the wire. See image below, ignore the ethernet connector.
4. Now open device manager in windows and it should show your phone under com ports as Qualcomm 9008 (COM #). If it doesn't try the process over again. When it does work remember this number. It is going to be used later.
5. Now fire up BoardDiag by willcracker be sure to run it as administrator. It is in this post named willcracker.rar There are some pictures on how to flash with this app but I will describe it as well. First we are going to need to extract your tot file. This can take some time. Like 10 mintues on a decent PC. The app may look like it froze up but it is just thinking. When it is complete move on to the next step.
6. You need to tell the program the com port that you are using that we found earlier and the folder where you extracted the firmware to.
7. once you have extracted the firmware and set up the program with the correct port you need to Check "AP" and "EMMC" then press start. Be sure not to select any partitions or change any other options than the firmware directory and comport.
It should come back as PASS. If it throws an error about not being in dload mode you need to restart the shorting process. Hold the short for a bit longer this time.
8. Flash all of the partitions except for Cache, System, Userdata, and Sbl1. Sbl1 will be flashed later and causes the phone to reboot.
You can flash System, Userdata, and cache but it takes a really long time so I don't recommend it. It is better to get your phone into download mode and use LG flash tool to do a full restore.
9. Once you have finished flashing all of the partitions one after the other put in the battery and flash Sbl1. Your phone will now reboot and try to boot into android. If your system is messed up it wont. You will still be in a boot loop. But you should now be able to enter download mode and recovery.
10. Open up LG Flash Tool and flash your tot using Board DL mode. Everything you need at this point is in the following thread http://forum.xda-developers.com/spr...de-how-to-restore-sprint-lg-g3-ls990-t2852042
Hope that this helps, also if you find any problems or need help please post so I can update this post.

Sorry I don't have that device to test. This is confirmed on the carrier version of the LG G3 only.

Thank You
I found a post similar to this that no matter where I looked - I was always referred back to that post - which was written in poor english - no download links worked. I appreciate this post. Saved my ass.

I have never had that error myself but it means either that you are using the wrong firmware images or that you have a hardware issue.

Several people have been having issues with hard bricks and there are several posts with a bit of info about how to fix them but no simple instructions so I'm posting a (hopefully) fool proof guide to fixing your hard brick. Tested on windows 7 and windows 10.
First what is a hard brick? A hard brick is a phone that does not boot, or is stuck in a boot loop, or has a security error AND cannot access recovery or download mode.
Disclaimer: Your warranty is now void etc. I am not responsible etc. You have to open your phone to do this so it is a last resort. Read the entire tutorial before beginning!
Required Materials:
Bricked LG G3
Stock USB cable <-- or at least one that you know is good
a short thin but stiff wire to short pins
Qualcomm high speed usb drivers
BoardDiag by willcracker <-- other versions don't seem to work
The tot file of the rom that you were running. (not older not newer same version) You can find these easily on XDA or google but it varies depending on your software version

I'm going to go insane. I'm stuck at doing the gnd and the capacitor. My laptop detects the device but it says devce not recognized. i installed the qualcomm high speed drivers you had in download on 32bit windows 7 and also tried on 64bit windows 8. Exact same thing, usb device not recognized. Also, I've installed the verizon lg g3 specific drivers and tried too but it doesnt work. Please HELP !

[Unbrick][Hard-Bricked][No Emergency Mode] LG L7 II (Single & Dual)

Hello to you all. Since I got a new device (LG G3) I thought it will be cool to write an in-depth guide about recovering a hard-bricked L7 II. Our guinea pig will be my P710. All devices have the same internals. I will write up when you need to do something different depending on your model. This will work for the people that flashed a P700 image and lost Emergency Mode. This will probably work in any hard-brick unless your eMMC failed or it is broken (physically).
FOR THE PEOPLE THAT FLASHED L7 FIRMWARE ON L7 II AND HAVE THE ODD EMERGENCY MODE AND CAN STILL SEE ANYTHING ON THE SCREEN INSTEAD OF THE OPENING AND SHORTING PINS GO HERE: http://forum.xda-developers.com/opt...unbrick-lg-l7-ii-flashed-l7-firmware-t3177181. Follow the Steps there and then return to this tutorial to the QDL 9008 part.
The original tutorial for this unbrick was made available on 4pda (Thank you very much guys; Your names will be in the credits area). Also some of the files (most of them) are from 4pda (Thanks again).
This is not exactly the same tutorial. I changed some things and I made some things my own way.
This is not a beginner friendly task but I will write it very in-dept (still not step-by-step). Very low skills are required though: follow exact directions, read carefully and don't do stuff because you think it is good.
I am not responsible for any damage to your phone, if you get fired from your job because your alarm clock failed or you destroyed your device even further. YOU TAKE THIS ACTIONS AND IT IS YOUR OWN RISK. I CANNOT BE HELD RESPONSIBLE FOR ANY OF THIS ACTIONS. This tutorial includes parts that might be illegal in some states (like changing IMEI back to your device one). If you are in one of those states please skip this. IMEI change is illegal (well, I am not a rule breaker but we are just gonna restore our default IMEI).
This Tutorial will be divided in parts:
1. Needed tools/drivers and preparation
2. Opening the phone and exposing the motherboard
3. Getting the device into QDL Mode 9008
4. Flashing the MBR, EBR and the main bootloaders
5. Flashing the phone as a Hard Drive in QDL Mode 9006 (Raw MMC Access)
6.1. Flashing a Pre-Rooted Image
6.2 Restoring the default Emergency Mode
6.3 Restoring original IMEI (if this is legal in your state)
7. Flashing your desired KDZ for your phone model.
1. Needed tools/drivers and preparation
Physical tools:
Frearson (Star) Screwdriver 2.0mm
Plastic Opening Tool
A cooper wire (not very big in diameter that is very sharp at 1 end)
USB Cable
Optional: A Loupe and a Motherboard Holder
Optional: A tool for releasing the plugs on the motherboard
This are my tools and of course the USB Cable.

Software:
LG Drivers
Adb for Windows
KDZ Flasher
QDL Drivers (32 and 64 bit)
QPST Tools (Qualcomm Service Tools)
MBR and BL Repair
EMMC RAW WRITER
HxD Hex Editor for Windows
Root.kdz
Stock_Emergency.rar
IMEI_Single.qcn
IMPORTANT: During all this tutorial RUN ALL PROGRAMS WITH RIGHT CLICK "Run As Administrator"
Download all the software and install Adb for Windows and LG Drivers and restart your computer.
VERY IMPORTANT STEP: When restarting and booting-up keep hitting F8 and get to the Advanced Boot Menu. Go down and hit “Disable Driver Signature Enforcement.” (AFTER THIS STEP DO NOT RESTART COMPUTER; It will temporary disable driver signature since QDL drivers are not digitally signed).
2. Opening the phone and exposing the motherboard
Open the back cover and plug out the battery. Plug out the Sim Card and Sd Card if you have any plugged. Using your screwdriver unscrew this screws.
Insert your opening tool (it must be a plastic tool like in the photo) above the power button and gently move it all across the cover so you unclip it. You can then lift off the cover and you will see the phone motherboard. If you get stuck in the case then lift up and down gently. Remove the 3 buttons and put them safe. (Power, Quick Memo, Volume).
Now remove the 7 connectors like in the image. CAREFUL. IF YOU DAMAGE ANY OF THEM YOU WILL LOSE THEIR FUNCTIONALITY. THERE IS NO WAY TO REPAIR IT. THEY SHOULD COME OFF EASY. Use your tool or your nail but with great care.
After that lift the motherboard (the green one) while you gently pull the connectors out of the way. Turn the motherboard on the other side and you will see something like this.
Hold the board in your hand and you will see the space above the battery connector. Pull gently with your nail until you hear it uncliping .
Turn it on the other side (not on the back, just rotate). You will see another space pull it up like you did it first time and pull the heatskin off. You will see something like this.
After this plug just connector number 1 and turn the motherboard on the other side (motherboard should not stay on connector number 3 you should pull that away when you turn the board.
We are done with this step

3. Getting the device into QDL Mode 9008
Now we need to use our polished cooper wire and ground 1 thin resistor to get to test-point mode. You need to ground this end of the resistor:
Ignore the white stuff (it is flux) on the GND point. Yours will be gold. Just short where the red dots are (the ground and the 6th resistor, the up pin of the resistor). While you keep it shorted plug in USB connected TO BACK PORT OF YOUR PC. BACK HUB NOT FRONT. If you don't get the beep for a new device detected unplug USB, short again and plug USB. After your device gets detected hold the short for 2 more seconds and then remove the cooper wire (or what you used to short).
I did it alone but you can ask 1 people to help. One keeps it shorted and 1 plugs USB. AFTER DEVICE GETS RECOGNIZED AS UNKNOWN DEVICE DO NOT UNPLUG USB OR YOU NEED TO SHORT AGAIN.
Go to Device Manager and select driver for your unknown device. Select the 32 bit or 64 bit driver you just downloaded at step 1 (depends on your OS if it is x86 or x64). Wait and your device will look like this.
Click Have Disk.
I have 64 bit PC.
FINAL RESULT SHOULD BE THIS.
4. Flashing the MBR, EBR and the main bootloaders:
After you got the Final Result install QPST tools and open eMMC Software Download. You will need the QDL_9008_L7II.zip files now. Do like in the image:
At 1 choose your phone.
At 2 Write:
Code:
MPRG8X25.hex
At 3 Write:
Code:
8X25_msimage.mbn
At 4 Press it and select the file rawprogram0 in your QDL_9008_L7II folder.
At 5 Press it and select the file patch0 in your QDL_9008_L7II folder.
At 6 Uncheck Program MMC Device
In the end it should look like this.
Press Download
Wait it to finish. Your device will make recognition sounds and it will say device ready to use. You are now in QDL 9006 (RAW MMC PROGRAMMING). The Final message should be:
You will see some messages like this:
The Letter might be different but ALWAYS DO NOT FORMAT. AGAIN!!! SAY CANCEL!!! ALWAYS
After you say CANCEL close eMMC Software Download.
5. Flashing the phone as a Hard Drive in QDL Mode 9006 (Raw MMC Access)
Open EMMCRAW program with Run As Administrator. You will need the LG_P715_FullFlash.rar. Unrar that and you will get a *.bin file we will need. Do like in the image and select the LG_P715_FullFlash.bin you just extracted. Then Press Write.
You might get a message like this:
If you get this press YES, if not it is just as good. If you will get the message it will stop at 99% flashing and give an error in the bottom left corner IGNORE IT. Wait until it is done and do not unplug the phone or restart the computer.
It will take up to 30 mins. After all buttons but Cancel are not grayed anymore it means it is done. Close the program. Unplug USB, Unplug the connect 1 on the motherboard and assamble the phone back like in step number 2 but in reverse order. DON'T FORGET ABOUT THE HEAT SKIN.

6.1 Flashing a Pre-Rooted Image
After you successfully assembled the phone plug battery. Hold down Volume Down and plug USB Cable. You will hear a beep and see some Strange screen with blue strips if you see this your phone is forever dead. Just kidding this is normal. Your phone is getting detected in this strange Emergency Mode.
If you don't see the blue screen it means you have L7 II Dual Sim (I am not sure since I don't have dual sim; this needs confirmation since I don't know if the OEMSBL is the same for Single and Dual). Do the 6.2 Restoring the default Emergency Mode if you see this blue screen like in the image.
Unrar the Kdz Flasher and from that folder install "msxml.msi". After that run "KDZ_FW_UPD.exe" as administrator. Do like in the picture:
1. Select 3GQCT
2. Select Emergency
3. Browser for the Root.kdz you downloaded at first step
4. Press the button and wait until your phone reboots
When it rebooted, unplug USB Cable, plug out the battery. Put it back. Press Volume Down+Home Button+Power Button. When it powers stop pushing Power. Wait until you see the Android Guy (this will hard reset your device).
When it booted up complete the Startup Wizard randomly to get to system. Go to Settings->Developer options and Enable USB debugging. Wait for drivers to install.
6.2 Restoring the default Emergency Mode
Plug in USB Cable.
Unrar the Stock_Emergency.rar and put the 3 files inside on the root of your SD CARD (you need an SD Card).
From ADB copy this. LINE BY LINE OR YOU CAN HARD BRICK YOUR PHONE AGAIN:
Code:
adb shell
su
Grant Su permission on phone.
Copy the next lines 1 by 1 pressing Enter after each one.
Code:
dd if=/storage/external_SD/cfg.img of=/dev/block/mmcblk0p1
dd if=/storage/external_SD/qcsbl.img of=/dev/block/mmcblk0p2
dd if=/storage/external_SD/oemsbl.img of=/dev/block/mmcblk0p3
Close ADB and reboot device.

6.3 Restoring original IMEI (if this is legal in your state)
This will include a split A (Single Sim) and B (Dual Sim). For Dual Sim restore I don't have a device and I am still experimenting it will be available later.
Be sure to have USB Plugged in and download, depending on your phone IMEI_Single.qcn or IMEI_Dual.qcn (not available yet).
Now we need to convert our IMEI to good form. Look under the battery and note down the IMEI on a paper (I will take as example 123456789123456). Apply this Algorithm:
Split the IMEI in 2 digits groups with the first group being 1 digit:
Code:
1 23 45 67 89 12 34 56
Add A in front of 1:
Code:
A1 23 45 67 89 12 34 56
Reverse order of characters in each group and you will get:
Code:
1A 32 54 76 98 21 43 65
Note this on the paper. Do this for each IMEI if you have a Dual Sim.
Look in device manager for your device under Ports (COM & LPT). See what COM your device it. We will note it COMxx (where xx is your COM number).
Open QPST Configuration and go to Ports window and follow instructions in the pictures:
Close QPST Configuration.
Open the IMEI_Single.qcn with HxD. Press Ctrl+G and write 22A49 and press OK. Write on Keyboard the IMEI after conversion (ex 1A 32 54 76 98 21 43 65) and Save the file.
TO COME FOR IMEI_DUAL.qcn
Open adb and do this:
Code:
adb shell
su
dd if=/dev/zero of=/dev/block/mmcblk0p6
reboot
When phone is fully restarted open Software Download (from QPST).
Do like in image.
Go to Restore at 1.
At 2 select the Port you just added in QPST Configuration.
At 3 select IMEI_Single.qcn.
Check at 4. At 5 Press Start.
Phone will reboot and you have Stock IMEI. Good Job.
7. Flashing your desired KDZ for your phone model
For this step follow 6.1 but instead of Root.kdz use the Firmware for your phone.
GOOD JOB FULLY STOCK. YOUR BRICK IS BACK. BIG THANKS 4 PDA. NOW CREDITS!. Part of tutorial and files are from here: http://4pda.ru/forum/index.php?showtopic=466295&st=3620#entry40156281

[GUIDE][G,U,Ch] DFU Unbrick Guide - Disassembly

DFU Unbricking Guide - When nothing else works

Heads-up: Now this guide is not the only way forward - EDL Tool has an integrated function to get out of DFU, and MultiDL (zte's tool) also works if you prefer MiFlash.
It is possible that you might still need to do a testpoint procedure to get into EDL.
Vick78 said:
4th category brick – phone status which does not allow to boot into next modes: Recovery, Fastboot, FTM, EDL. In Windows Device Manager the phone detects as ZTE Handset Diagnostic Interface(DFU) (COM...) whrn you connect it via USB cable. Any of possible manipulations give the same DFU mode (even when you force to install Qualcomm HS-USB QDLoader 9008, in reality it is still a DFU mode).

This guide is based off of @Vick78 's 4th Category Brick Repair Manual. I had to follow the guide in mid-April, and after doing it I realized that rewriting the thread would help all of us.
Please thank Vick78 on the other thread. I've been endlessly sending people there to fix their phones, and it works like a charm.
All of this is at your own risk, however obvious that may be... If you don't think you can make it, take it to someone experienced and show 'em this guide.
Patience is key! Be really careful when doing this, or you can break something inside and lose functionality. Flex cables are awful.
0) Know your Model:
Turn your phone around and see what model it is. If you screw up and flash another model's ROM you can lose your IMEIs.
In some cases (AliExpress) the phones come with A2017G software even though they are A2017 models. Just beware.
1) What you Need:
• A Windows PC with (preferrably) 64-bit support. Win7 will do, although Win10 may make stuff slightly easier. If it is a tower PC, use the rear USB ports, not the front ones!
• Your corresponding FULL_EDL package. Download it from @WesTD 's Latest Stock ROMs thread. (Thank him too! :good
• MiFlash. Get it from Yandex or Mega, same file. Thanks @djkuz for the link.
• Metal paper clip or needle to short circuit the test point.
• Tiny Phillips screwdriver or at least a knife, to get the screws off.
• Stock USB cable, or at least one that works good with data transfer.
2) Disassembly Video
JerryRigEverything made a full teardown video. Watch the teardown part a couple of times (up to 3:40) until you're familiar with the parts. You don't have to take the speakers or the USB-C module off though, just keep them there.
3) Teardown Hands-On
Images are also from Vick78's thread.
Make sure that the phone is completely off before starting! Also take the SIM card tray off before separating the screen from the back housing or you'll break something
a) Take the speaker grilles out by prying on the edges. You don't need a heat gun for this. Remove the black material to expose the screws, but be careful not to break it if possible, because it protects the speakers.

}
b) Remove all the screws and VERY CAREFULLY separate the screen from the back housing, to avoid breaking the FP sensor's flex cable. After that, disconnect the FP cable with your nail or some preferably non-conductive thing
c) Take the protective metal piece out, then disconnect the battery, USB-C and display/power connector, then get all those screws out. Put them somewhere so that you won't lose them (piece of tape, maybe a magnet).
d) Take the motherboard out and disconnect the antenna wire that's below it, on the lower part.
e) Disconnect the rear camera. Leave the front one connected.
And now you can see the TEST POINT that you have to short
f) Since the testpoint is in the back of the motherboard, and you need to have the battery and USB-C connected, I advice you to pry the battery off. You can rupture it very easily though. If you don't want to do it, don't worry, it is possible to make without taking it off, but you might break a flex cable and, honestly, it's much harder to hold the connection on the test point while the mobo is facing downwards.
If you will pry out the battery, be REALLY careful and don't force it.
g) Put the motherboard with the test point facing towards you. Connect the battery and the USB-C module to it, and the USB-C cable to the USB-C module (But NOT to the PC yet!). Be VERY GENTLE with the "little lego connectors" as I broke a couple of pins from the USB-C connector (It still works fully, I believe they have redundant pins in case someone like me screws up)
4) Connection to the PC
Before flashing, we need to make sure that the drivers are the correct ones.
- Open Device Manager (if on win10, right click on the start menu button and select device manager), find "Ports (COM & LPT)", and open it. Leave Device Manager open for now.
- Find an USB port on your PC that you can reach while you short circuit the test pad. If you have a desktop PC, it has to be one of the rear ports (NOT the front ports, those have a lot of interference) and they should be USB 2.0 if possible.
- Take the clip and connect the test pad to the big chunk of metal that's right beside it:
-Insert the USB cable (previously connected to the phone) to your PC's USB port.
-Watch Device Manager now. The phone should appear as "Qualcomm HS-USB QDLoader 9008". If it does, just go to the next point. If it doesn't, see if it is called "QUSB_BULK" under USB devices (This happens if you used Zadig). If this happens, find the QUSB_BULK device, right click, Uninstall device, Delete the driver software for this device. After that disconnect the cable from the PC, disconnect the battery, and connect it again; and redo the clip thing up to this point. The correct driver should install itself.
5) MiFlash
- Open MiFlash, keep it ready
- Unpack the FULL_EDL file to a folder with the same name, then open the folder and make sure that the files are directly there (i.e. they aren't inside another folder), put it somewhere, and select it from miflash ("select" button, select the folder).
- Hold the connection with the clip, as stated in the image above
- Click on Refresh from MiFlash, as soon as it detects a device hit "flash"
- If all goes well, it should say "send configure command". Wait 3 seconds and get the clip out. If it doesn't get to this part or if it fails, just disconnect it from the PC, disconnect the battery and reconnect it, and try again. Do this until it succeeds and it flashes. You might need to do this more than 5 times! If it doesn't work, try leaving the test pad connected for more or less time, like 2 seconds, 2.5 seconds, 3.5 seconds, 4 seconds... But 3 seconds works for most.
-If the flashing works, once it ends, go to the recovery and factory reset the phone. Otherwise there might be conflicting information in /data.

actually you don't need to open your phone. I was same situation and made a deepflash cable. it needs a little electronic ability and passion. you can enter edl mode with this method but it is too hard and you must be very patient.
I got edl mode one time but miflash didn't install correctly stock rom and couldn't again. @asderdd helped me and my device is okay now.

The deep flash cable works only sometimes. I didn't try but most people bought a bunch of normal ones and they didn't work

@Choose an username... bro should I take out the daughter board (which held usb c port) too? what should I do about the usb c module u've mentioned above?

It's not necessary, just taking out the board and the battery is usually enough. Be careful with the USB-C flex cable though, those are fragile

just my 2 cents here, better off getting cable like this
https://www.amazon.com/gp/product/B06XXCLMGM
bought one just to have one in any sort of emergency and even tested and works like a charm and is not just for ZTE devices but any snapdragon device out there....

And? Did you manage to pull it back together?

I have my Axon 7 since March 2017. After a month of owning it, when Android 7.0 was released, I rushed to flash a chinese rom. The result, a nice brick.
I tried with 3 EDL cables and shorting that pin, many many times. No luck. So back then I decided to put the phone back in its box, forget about it and move on. So eventually I purchased a new phone, wich I hated so much because it was more expensive than the Axon 7 and lacked in every aspect. So I sold it as well, and bought another phone, which I loved, but again, lacked in comparison to the Axon 7, until I was mugged. So I remembered that I had an Axon 7 lying around in its box, and decided to search XDA for a solution. That's when I found this thread and I decided to try and revive the phone.
All can I say is thank you. You brought my beloved Axon 7 back to me.
Thank you so much.

Thanks for the Guide! Annoyed at myself for my bonehead move that got me here in the first place, no biggie though as I used to repair phones for a living. If was any good with solder, I'd contemplate sticking a dab on that pin and never worry about not getting into EDL Mode again. I really like this phone, but the crap they've pulled in making it a nightmare to tinker with has me not desiring to get another one ever. OnePlus will probably get my next dollar set cuz of how open they are currently.

i don't think that would be a good idea. your phone would probably ONLY enter EDL mode. But I thought seriously about soldering a pushbutton on it. thing is that if you somehow rip the pad off, your mobo is dead.

Thank you for this guide my phone is working on chinese rom now but the big problem is
i cant flash any thing now .
vol up + pwr then the fastboot keep restart
vol up + vol down + pwr send me to dfu mode
vol down + pwr send me to ftm mode and when i send (( adb reboot edl )) i get qualcomm usb but mi flash keep say (( can't receive hello packet )) i tried many many times with 3 versions of mi flash but nothing works
please help me i cant live with chinese rom .

Try Flashing with the Axon 7 EDL Tool. The problem can also be the EDL package you are trying to flash. Try now a different one. If you can get to EDL mode, then it should work.

Woke up today to see my phone not turning on. Having troubles booting up and when I choose to go to recovery or fastboot through the unlocked bootloader warning menu it just bootloops. I connect my phone to my PC and it is already showing the "Qualcomm HS-USB QDLoader 9008" in device manager. Do I still need to open my phone and do the paper clip test in Step 4? Or can I continue on with the rest of the guide?

You should be able to just connect and do the final part. As long as your emmc is all right, of course

Thanks for the quick reply. Heh, how often is flash storage failing a problem with other users? =X

Maybe I've seen it once, but i'm on the q&a section all the time, so it's extremely rare. If it tries to boot then maybe it's just something much simpler

From FTM mode ( hold volume + and plug in USB cable) adb should be enabled. If the phone has a Qualcomm chip and Qualcomm drivers have been installed on your computer. Use "adb reboot edl" to reboot the phone into edl / Qualcomm 9008 mode. No need for cables or tearing the phone apart. This does not work on every phone.

Successfully flashed B35 EDL. Phone is unresponsive to any power or volume key presses. MicroSD card is removed. Still no cigar. Can't get the phone to be recognized as EDL mode anymore either. Phone detected with different USB port for EDL. Flashed again. Still nothing. Any suggestions? I still have the option of taking the phone apart, but that is a last resort if that makes the ability to RMA void.
I can feel the phone warming up when I plug it into a charger. That's the only sign of life I see in the phone.
