Hard bricked E970? Maybe not! - AT&T LG Optimus G

After one of my at twice weekly full nandroid backups to microSD I attempted to revert to an earlier release of the custom Marshmallow ROM I had updated from. A failed TWRP 3.x dirty flash, gave me an error message that it was unsuccessful and I could not turn my phone on or (obviously) get to Fastboot. My phone would not respond to the power button or anything else. While steps later I discovered that my power button is malfunctioning (more on that later) it did not change my QHSUSB_BULK, Qualcomm HS-USB QDLoader 9008 mode issue.
When I plugged my phone into my laptop running Windows 7 there was always an acknowledgment sound and Device Manager showed a device QHSUSB_BULK with a driver issue. This matched the numerous "Hard Brick" posts on numerous sites referring to the LG Nexus 4 (E960), our E970 and Optimus G Pro (E980) which largely share the same chipset in addition to numerous other newer phone models from LG and others with Qualcomm chipsets.
Numerous old posts stated that a JTAG repair was my only hope of reviving the late 2012 model phone that I have had for 3 years. Finding no one in driving distance with JTAG equipment, the prospect of paying $50 + two way shipping (likely approximately $70 total) seemed like an unwise investment for old hardware regardless of how much I still like it. This was reinforced after perusing eBay and my local Craigslist for suitable, somewhat newer, replacement models. While I had successfully replaced my battery months ago, I am not inclined to connect wires to anything on the motherboard to short and possibly reset anything.
== Bottom Line ==
What ended up getting my phone back to Download Mode was following a portion of the instructions here ==> http://open-freax.fr/guide-unbrick-your-lg-g3/ with a couple of changes.
You have to get the Qualcomm HS-USB QDLoader 9008 mode without any Window driver error, BoardDiag by willcracker, and an E970 TOT file ( LGE970AT-01-V20j-310-410-MAR-08-2013+0.tot or similar) before you can do anything. I ended up using an old laptop of mine (Netbook actually) since I still got a driver error after installing the 64-bit Qualcomm 9008 driver on my primary machine. I never connect my OG to that old laptop and it is running 32-bit Windows 7.
Due to my power button issue I ended up taking the back off my phone, disconnecting the battery, and putting it back in my Diztronic rubber case since LG stuck us with a non-removable battery.
E970 variation from what is detailed under "Now , let's get the party started" are in the "AP Chipset" (ours is MSM8960). The Com Port is specific to what is in your Device Manager where the QLoader 9008 shows up. As detailed, if the EMMC TEST shows a problem you are wasting your time proceeding since you have a hardware problem.
Another E970 variation is in the paragraph starting with "Now untick EMMC Test select" which is the 3rd paragraph before "Step 3: back to stock"
- There are no files with the name dbi or laf generated in our TOT extraction so skip those but proceed in the order stated.
- In the following paragraph, after flashing Sbl1 go ahead and flash Sbl2 & Sbl3. I have no idea what they do and someone more knowledgeable may say they are not necessary but it worked for me.
After that I was able unplug (remember my pwr button is not working) hold down both volume buttons, plug back in and I was in Download mode. From there I could use LGNPST which means I was no longer "Hard Bricked" but Soft Bricked, which is not that big a deal. You will not need "Step 3: back to stock" if you follow posts in XDA about Soft Brick recovery methods like Teenybin or other.

Wow, sounds like quite the process. I'm happy to know you got it working again!

Boiled down...
Once the Windows drivers are loaded and properly recognizing the phone it should not take more than 15 minutes (not counting TOT file download if needed) and not involve phone disassembly to get it into Download mode.
After my overly long post I realized that my replacement battery (in use for months) despite being identical to my OEM battery other than the date stamp, had been malfunctioning and my power button is fine. I am back to using my original battery. The process took a bit of trial and error and days for me to figure out.
The G2 (AT&T version) I snagged on eBay was delivered today but battery is discharged so I will fiddle with it after charging. Physically it appears in excellent shape but until I am able to fiddle with it I will withhold judgement.

My lg e970 is hard bricked and i need adb dump/backup to revive that . if someone can provide that it will be of great help . the procedure to create adb backup is mentioned below. i hope some noble soul will help me smile
step 1: root your device.
step 2: go to setting > about > software info > build info > tap 5-6 times until message getting to enable developer mode.
step 3: go to setting > developer option > usb debugging >Turn ON
step 4: open your PC and run adb t from cmd.exe
step 5: run this command then check your mobile screen for grant su permission.
adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/Alive_Dump.bin bs=1024 count=1048576
step 6: AFTER THAT create 1GB dump in your phone internal main storage.
find name “Alive_Dump.bin”
note : command are case sensitive so try to direct copy paste better for no error.

[Q] Dell Streak (White) Stuck logo flashing lights loop

Hello & yes, yet ANOTHER person with this issue. This is what I've done:
It all started by going out to unlockr's page & following their rooting how-to. When I did this it put it in the never ending dell screen flashing lights loop. I've researched quite a few hrs on this. This is what I tried:
1) Doing factory restore (holding volume buttons & pwr buttons down) & choosing restore.
2) Borrowed a buddies SD card & tried a restore (did nothing)
3) Followed a couple of guys instructions on doing a restore one of them being here: http://forum.xda-developers.com/showthread.php?t=776883
After following the directions I did see it look like it was updating back to the 1.6 OS, but after it rebooted it was still stuck in the Dell flashing loop cycle.
SO I did probably the dumbest thing I could do & took it back to Best Buy who is shipping it off... most likely to get my warranty canceled, but I didn't know what else to do. I had purchased their protection plan, so I'm not sure how it's gonna go. They would have replaced it in the store, but I had already returned my 1st one as it wouldn't boot right out of the box (not my fault).
So I figure if they don't flash it at Dell & get it back to working, I'll have to keep working on it myself to correct the issue....
So I guess my question is, any advise on why mine is being so difficult or is this just the way it is & it takes several attempts to flash these things sometimes? Or has Dell implemented a security feature in the new releases & that's what is causing my headache?
Those of you who feel the need to rain down the "Dumb thing to do returning it" please save those comments as I've already stated "I know".... I just need some positive input on getting this thing back on "it's feet" IF Dell doesn't fix it for me.
I will keep you posted on the Best Buy/Dell Drama that I'm sure will start up... I will say that if it's not fixed, I can't say that I'll continue with paying Best Buy $10 a month for a protection plan, as they supposedly will replace the phone if it was damaged in any way. If anyone has info or a story on that part of it I'd like to hear it as well.
Thanks in advance!
Look for the upgrading downgrading guide in xda. Nornally starting from 4399 build is a good start to get you back up and running.

DON'T USE THE UPGRADING/DOWNGRADING GUIDE!! IT WILL BRICK YOUR WHITE STREAK!!
The white Dell Streak is known to have something different going on with it. There is a special tool (QDLTool) that is needed to upgrade it/unbrick it. It takes you directly to stock 2.2 and you can do what you want from there. See this thread here for more information and a fix.
http://android.modaco.com/content/d...24010/warning-white-dell-streak-is-different/
Thanks for the knowledge! Didn't know there was a difference, although I suspected something was amiss when I was doing what I was instructed to do but not getting results....
Any more info is appreciated so keep it coming!!!
erm not that im saying this BUT you got protection(inshureance)accidently drop it in a sink full of water or some such like acident pay your excess and get a new one.
but i dint say that.There norm pritty good at replaceing your phone after such an acident
We'll see what happens when I get the phone back... the post from TopShelf95 may just have saved it from a fate similar to that! HA!
FOR WHITE DELL STREAKS
You'll need the QDLTools for this... so please search/google the links or posts for that.
Typed instructions from these posted from videos that I can't link to yet as I'm a noobe here...
(Hope I didn't fat finger & mistyped anything so be on the safe side & don't cut and paste command line stuff)
1) Start, type CMD in the “programs search area”, CTL, SHIFT & Enter to start command window in Admin mode.
2) Type “bcdedit –set loadoptions DISABLE_INTEGRITY_CHECKS & press “enter”
3) Type “bcdedit -set testsigning on” & press “enter”
4) Reboot
5) Go to the directory where you’ve stored the QDLTools (ex. C:\Streak\RepairTool) , then into the subfolders until you find the driver folder, open the subfolder “Driver_2.067”, Then “Test Certificate” .
6) Right click on qcusbtest & install cert
7) Choose “place all certificates in the following store” & browse
8) Install cert in the “Trusted Publishers” store, when done click “Ok”
9) Right Click on the qcusbtest cert again & select “Install Certificate” again
10) Choose “place all certificates in the following store” & browse
11) Now install cert in the “Trusted Root Certification Authorites” store
12) Click “Ok” when done
13) Remove & replace battery in Streak.
14) Hold down the Volume Up button & plug in USB cable
15) PC should detect connection & install drivers (which will fail)
16) Open control panel & go to device manager
17) Locate the “Qualcomm HS-USB Diagnostics 9002” (if it doesn’t have a yellow exclamation mark by it, you have the driver & can skip forward to
18) Right click & select “Update Driver Software”
19) Select “Browse my computer for driver software”
20) Select “Let me pick from a list of…”
21) Choose “Show All Devices” & click “Next”
22) Click on “Have Disk” & browse to the repair folder, drivers are in the Driver_2.067 folder, if you are using 64bit OS go to WIN64 (Win32 for 32bit)
23) Select WNET unless there is a folder for your version of Windows (for 64bit choose AMD64 unless you have an Intel Itanium CPU)
24) Select “qcser.inf”, click Open, then “Ok”
25) Choose “Qualcomm Incorporated” & choose “Qualcomm HS-USB Diagnostics 9002”, then click “Next”.
26) Click “Yes” if you get an Update Driver Warning dialogue box, then “close” once installed.
27) Now go back to QDLTool folder
28) DISCONNECT USB CABLE FROM STREAK
29) Start the QDLTool utility
30) On the QDLTool Upgrade Build screen the area “Device” with “Port:” in it should say “Not Connected”.
31) Make sure USB cable is UNPLUGGED & remove batter from the Streak.
32) LEAVE BATTERY OUT FOR AT LEAST ONE MINUTE
33) Replace battery & install back cover on Streak
34) Hold down Volume Up button & connect USB cable to go back into diagnostics mode
35) “Port” in the Device window will change to ”Qalcomm HS-USB Diagnostics 9002 (COM4)” once the Streak has been identified.
36) Click “Run” to start the update. Takes from 3 to 4 minutes typically.
37) IF YOU GET A FAILURE AT THIS POINT go back to steps 31 thru 34. Wait for step 35 & follow 36.
38) When it says “Waiting for Reboot” your Streak should reboot itself, ready to go into Fastboot mode
39) IF IT FAILS AT THIS POINT: your ADB drivers for fastboot are not installed correctly, so fastboot may be erroring, install drivers & restart steps 28 thru 36.
40) At this point your device should have been updated & should soon finish booting into the updated Android release.
41) Take your PC out of Test mode by going to “Start”, type CMD in the “programs search area”, CTL, SHIFT & Enter to start command window in Admin mode
42) Type in “bcdedit /deletevalue loadoptions
43) Type in “bcdedit –set testsigning off
44) Reboot

Solution # 2
Take the phone back to where you bought it and get the black one.
As some of you may know my white one met similar fate and after hours of getting no where i just took it back and got the black one.
after 20 minutes of getting it home i had froyo 2.2 running on it.
besides..do you really want a white phone? lol
i didn't. they were supposed to give me a black one to begin with..
I told the returns lady i wanted a black one and they gave me a white one. when they booted up the phone it didnt boot and they did not say one word. they just went and got me a black one.
Frankly this was the only reason i bought one from bestbuy..
it certainly wasnt because of their pricing
Good luck.
Bigfoot, if you'll reread my original post you'll see that I've already returned one & tried to return the white one, but they would only allow one instore return. I don't care if it's white or black (I'm not racist HA!) it's gonna be in a Otterbox Defender anyway. I just want a phone/tablet that works at this point.
We'll see how the above mentioned "fix" works if I have to install it when I get my phone back.
I have the white streak too and I can tell you that the QDLTool works like a dream. Just follow the instructions to the letter and you will have 2.2 on it in no time. The Streak is virtually impossible to perma-brick. Since QDLTool works on a lower level than fastboot, it will work even when all else fails.
Awesome again good to know!
Does the qdltool work for the black streak?

FINALLY (update)
So after 42 days I FINALLY got my phone back from Best Buy... WORST customer experience... I would tell the whole experience, but I'll just make it short... they couldn't find it at one point, they shipped it back 42 days later, my 16 gig sd card is missing from it & when I got it back, they'd not reflashed the phone. So they did nothing but basically steal my sd card & gave it back to me....
ANYWAY.... After I went back to BB to find out what they were gonna do about my phone not working (which I'll have to call mgr tomorrow) I got home & followed the instructions given in this thread to flash my white dell streak & IT WORKED!!!! No issue 1st time around... Perfect, almost as easy as jailbreaking an iPhone... THANK YOU VERY MUCH FOR THE HELP!!! You guys are awesome...
Now... I have a friend who is also asking will this process work for the Black Dell Streaks... so will it?
also
this puts your system into an unlocked status which enables you to download the official Dell 2.2 ver. One downside to it is it shuts off your wi-fi hotspot...
Good thing about the Dell ver. it fixes the buttons sensitivity for one thing that seems to be an issue on the QDAtools ver... I'm sure later builds that is fixed though (would think it would be)
WRONG
I was wrong (looked in the wrong spot) wi fi hotspot is there... my bad
so by using the tool method on my white streak, does it mean my phone is rooted? or is there more i need to do to root my white streak?

No, it won't be rooted. But that's easy to do. You can stay with Dell stock ROMs (download from their website) or go with DJ_Steve's ROM which is rooted and has lots of other features. Rooting isn't hard, though, if you stay with stock. Just use Super One Click and you'll be good. I'm not sure if either method is supposed to work, but my wife's only was rooted by the second method (rage against the cage or something like that).
Also, QDL Tool works for both black and white streaks.
I have the same situation as the OP. However when I try the instructions I make it all the way to the part of running the QDL tool. There I get an error message at about 12 seconds, during the section just after Run HEX success. The error says:
ERROR[D14]:streaming hello Failed!
ERROR: Download fail!
It then says to remove battery and try again, which I do and get another failure.
Any thoughts besides taking a hammer to this thing?
after the first time it went through the fastboot (Downloading AMSS) it rebooted and I had to manually put it back into the fastboot mode (hold camera) for it to fishing writing everything else.
It Worked Perfect!
I've moved on to the Samsung Galaxy Note... My Streak did it's year or so service as well as it could (it's still working without issue) but I wanted a phone that had actual support, I am an IT tech by day & just don't wanna have to mess with yet another system that I have to do go thru a few hundred pages of forums to figure out the true method of getting something to work or install. iPhone hackers have Android beat in that area for sure... 1 click root/jailbreak is the way it should be.... but iPhone doesn't have a 5.3" screen!!!!!!

Rooting MTK6589 KVD Apollo One

Hello all,
I have googled, and searched forums high and low to no result so I thought i'd ask.
I recently purchased "KVD APOLLO ONE K6589 Quad-Core Android 4.2.1 WCDMA Smartphone w/ 5.5"
Im new so I can't post external links, however if you go to google or deal extreme and search, you'll find it easy enough.
The phone itself was next to nothing ($180) so even if its Unrootable, I'm not too fussy.
I would however prefer it rooted, I have read that you can basically use the MTK6577 rooting tool on the device?
Would this risk bricking the device.
I'v attempted to contact the manufacturer however to no avail! This is a rather new model so I know im being a tad impatient but if anyone can help then please do
Thanks guys

Also looks like im getting the Star N9589 just due to the more support available.
Anyhow until then, failing any answers from here, another chinese forum a spanish one and Yahoo answers I am going to go with the following method, If it dies, It dies this was my own fault for not doing enough research and at least it lets others know. I would send it back to DX But cba with postage fees and the hassle;
THIS IS DONE AT YOUR OWN RISK! -
APOLLO ONE - MTK 6589 K6589

Guide by philipkroberts Twitter @philipkroberts
Revision 1 - People to be added to credits for leehed source, currently untested, concept only
Before anything try and boot into any form of recovery mode and backup if possible!
DISABLE UAC in WINDOWS 7
RIGHT CLICK RUN AS ADMIN ON ALL FILES
ALLOW NON TRUSTED DRIVER INSTALLATION (Google this if unsure)
On the phone install anububu on pc phone. - See what model it detects as and note it down.
Run MTK DROID TOOLS and connect phone see if drivers After a few seconds, the box should turn blue, and it should say "Apollo ONE or Other Name " besides it. The drivers are working.
If not try the other drivers in the drivers folder using device manager, there are many tutorials for this I cba typing one im so tired! and make sure you have the only trusted drivers thing turned off, if you constantly get unknown driver then your out of look and wil have to try and source some yourself.
Win7 (This method has not been tested by myself. Confirmation required.)
HOW TO MANUALLY INSTALL ANY DRIVERS IF NEEDED
a - Downloading This tool Called EASYBCD
b - Use it to restart your computer in advanced boot mode. (PRESSING F8 WHILST BOOTING UNTIL YOU GET THE OPTION FOR Disable signed driver enforcement)-Must be done everytime you wanna root a phone with this method.
c - Follow instructions and disable SDE.
d Manually install drivers, if above did not work (Yellow sign issue)
e Navigate to control panel - > Hardware and Sound - > Device Manager
f You should see a driver notice with a yellow warning sign next to it.
g Right click on it and choose "Update driver..".
h- Manually assign drivers, usually the choice furthest down.
i- In the window which should have appeared, navigate to the preload/Mt6590 folder and press OK.
j- If SDE is turned off, you should see a red warning window. This is normal, just accept the message prompted.
k- The drivers should now be successfully installed.
l - Once this is done open C:\Users\Hate\Desktop\Chinese Droid Rooting\MTKROOT TOOLS\Root_with_Restore_by_Bin4ry_v28\runme.bat Hope it ****ing works if so your rooted, If not try this next few steps, AGAIN at your own risk, no need to format just continue from here.

0 - Use PC to copy UPDATE-SuperSU-v.1.25.zip to the root of SD CARD, do not unpack just leave whole zip there.
1 - Turn off your phone, remove your battery. (Do not connect your phone to the computer yet!)
2 - Navigate to the "SP Flash Tool" folder, and run the tool.
3 - On the right side of the tool, there should be a button, iconed with a folder, named "Scatter-Loading". Click this.
4 - Navigate to the "Yulypis Recovery" folder, and double-click on the "Mt6589_Android_scatter-emmc.txt".
5 - You should be back at the SP Flash Tool start-screen, and there should have appeared a list of text and hex-codes.
6 - The "Recovery" line, should be ticked off, and preloader should be red.
7 - Now, click on the button named "Download", with a blue arrow on it. Press "YES" on the NOT ALL images has been correctly loaded warning.
8 - Connect your phone to a USB 2.0, with removed battery. The program should now work, and if drivers is set up correctly, the 0% will turn 100% and a green circle will appear in the middle of the screen. If your phone disconnects before the flashing tool is able to recognize your device, try putting the battery back into the phone before running SP Flash tool. Additionally, if this doesn't work, try using different drivers in the drivers folder
9 - Disconnect your K6589 from the computer when you see the green circle, insert the battery and boot the phone. Wait for it to get to the start screen.
11 - Installing SuperSU through Yulypis recovery
12 - Run "MtkDroidTools.exe" from the folder.
13 - Connect your device, and after a few seconds, information about your device should appear.
14 - Click on reboot, on the mtkDroidTools start-screen, and choose "..recovery".
15 - If recovery has been properly flashed, your device will now enter Yulypis recovery. Blue, with english text.
16 - Controllers: "Power = Enter, Initialize", "Volume down = Scrolling down". (Don't remember if volume up was bugged or not)
17 - Enter "Install zip from SDcard" - > Navigate to the earlier copied "UPDATE-SuperSU-v.1.25.zip and initialize it by pressing the power button.
18 - Follow the on-screen instructions, and it should be prompted to install after 1-2 more screens.
19 - Reboot the device by clicking on "+++++back+++++" and "Reboot now / Reboot Device".
Either way I am going to smash this in a week or so when the phone arrives from DX and will keep people update.
Peace
Please I want to buy this phone. Can you answer me a few doubts I have?
- How is the viewing angle? Cause i purchased a tablet from china and the angle is very bad.
- Has proximity sensor?
Are you ok with the phone?
thank you.

I'm still awaiting the phone, hence why that guide is at your own risk.
However from what I have been told and gather that should root the phone no problems.
As for custom roms, I wouldn't even bother trying!
Once the phone gets here I will test my tutorial and re-write it into a more easy on the eyes fashion.
Thanks
http://www.fastcardtech.com/APOLLO-ONE-K6589?u=37825
They sell the phone, for an extra $3 they root before sending.
It cant be that hard, I'd love to know someone in that factory!
I'm looking for a link to download the full stock firmware for this device.
Anyone, please?
...or at least a firmware dump from a non-modified working phone.
One could use MTK Droid Tools and SPFlash to perform this task easily.
PM me for assistance if you need it.
Thank you.

[Q] Reviving a bricked nüvifone A50?

Good evening,
well, you could call this post my "last hope" to find some support when it comes to turning a seemingly completely bricked GARMIN/ASUS nüvifone A50 into something better than a dim glowing paperweight...
I got this device as a "present" with the quote "hey, maybe you can do something with this". Sure, after spending some searching online I should have thrown it at the former owner - WAIT, I didn't mean that
What does the A50 do? Only low level stuff like showing the bootup screen, the charging screen, I can enter the "wipe userdata" mode (which is supposed to restore the phone contents from a hidden partition) which does NOTHING (performed several times, even overnight) - and I can enter the "USB POLLING MODE" which also leaves me clueless.
I attached the device (in USB POLLING MODE) to my windows box and a running ADB - no device found. The only reaction I get: in the device manager panel I see the device "ADB INTERFACE" and the "Garmin-Asus Android Bootloader Interface" show up as soon as I connect the A50.
When I start up the A50 "normally", it stays stuck at the bootlogo - connected to the PC I get two drive symbols appearing, but not readable from windows - and using the "properties" of the explorer and the device manager I see only "0 bytes" capacity.
Seems that the complete flash including the recovery partition has been wiped - there go my hopes.
Is there a way to construct some kind of emergency boot file on the SD card to get the device in a responding shape? I'm afraid that GARMIN points me to ASUS and vice versa as this device has been discontinued some time ago. And for me it's just a question of honor to bring it back into some kind of working condition. Yes, failure IS an option here, but if somebody has any clue for me, I would be really happy.
Anyway: best wishes for the new year!
Cheers,

[HOWTO] Firmware flashing for CAT B15Q

So, here is the firmware flash guide for B15Q. It assumes either a Win7 x86 machine or a x64 with driver signature verification disabled (but Win8/8.1 in any variant or W7x64 is NOT RECOMMENDED).
I assume no warranty for bricked devices, especially not if you manage to kill your PRELOADER or DSP_BL. Double and triple check before downloading.
0) Driver and toolkit setup
Get the driver set, scatter file and spFlashTool from this thread: http://forum.xda-developers.com/general/general/stock-rom-cat-b15q-rom-development-t2988774
Remove back shell from phone, remove battery (!)
Attach phone via USB. Windows should now, approx. once every 2-3s, make a sound similar as if you put in a USB stick and then pull it out again.
Start=>Run=>devmgmt.msc, in the View menu choose "Devices by connection"
Click yourself through the tree until you find an unknown device (MT65xx Preloader or similar)
Rightclick on the device and press "Install drivers"; you shall find the drivers in "MTKUsbAll_0.9.2\New inst. win 7&8x64" folder.
Launch "SP Flash Tool v5.1352.01\flash_tool.exe"
In the tab "Download", click on the "Scatter loading" button and select the downloaded file "MT6582_Android_scatter.txt". spFlashTool usually remembers this across restarts.
Unplug the phone at the computer side if you want to work with it later (the MicroUSB ports don't like too many inserts, they wear out physically).
A) ReadBack for backup of existing firmware/userdata
This will involve a ****load of typing for the first readback.
Open the scatterfile using Notepad++ or any editor capable of handling UNIX line endings, NOT notepad
You will see a lot of blocks like
Code:
- partition_index: SYS0
partition_name: PRELOADER
file_name: preloader.bin
is_download: true
type: SV5_BL_BIN
linear_start_addr: 0x0
physical_start_addr: 0x0
partition_size: 0xC00000
region: EMMC_BOOT_1
storage: HW_STORAGE_EMMC
boundary_check: true
is_reserved: false
operation_type: BOOTLOADERS
reserve: 0x00
In spFlashTool, select the "Readback" tab.
For all the blocks you see in the scatterfile (IDs 0-23), repeat the following:
Click "Add"
Double-click on the newly appeared row
Choose a filename (e.g. preloader.bin for the first block; some blocks will have name = NONE, use the partition_name here for the filename) and click SAVE
A window "Readback block start address" will appear
Choose Type = "hex". Copy (Ctrl+C,Ctrl+V, and take care to exactly select the hex value! Do NOT type the hex values by hand!) the value from linear_start_address (with the 0x) into the "Start address" box and the partition_size value in the "Length" box, press OK.
Unless you are at the SYS23 partition BMTPOOL, proceed to the next block, repeat from above.
The SYS23 partition can not be backed up, because it has invalid lengths. Do not enter it into spFlashTool.
CHECK THE VALUES FOR START ADDRESS AND LENGTH IN THE TABLE. CHECK THEM ANOTHER TIME.
Press "Read back" button at the top.
Plug in the phone with the battery removed(!) and wait. This process will take time and consume approx. 3-4GB of disk space.
Archive the files you created somewhere safe. Do NOT distribute anything to other people except the BOOTIMG, RECOVERY and ANDROID partitions, because the other partitions contain data that is hardcoded to your board (e.g. IMEI/MAC addresses, sensor calibrations,...) or your private data and app data (SYS22/USRDATA).
If you want a full backup to disassemble by hand lateron (aka you trust in nothing going wrong and don't want to do the hard work except when you need it), just create one readback section with start=0x0 and length=0xE5720000 - this backups everything in one file.
B) Download for flashing new firmware
In spFlashTool, select the "Download" tab
In the dropdown box below the scatter file, keep it at "Download only" or set it if this is not the case
Uncheck all the boxes in the table
Double click on the "Location" column of the BOOTIMG, RECOVERY, ANDROID or USRDATA rows which you want to flash, select the appropriate image file.
Check that you selected the correct images for the correct partitions!
CHECK THAT ONLY THE ROWS WHICH YOU WANT TO FLASH ARE CHECKED. ESPECIALLY, NEVER EVER CHECK THE PRELOADER, MBR AND EBR PARTITIONS. YOU HAVE BEEN WARNED.
Press Download
Plug in the phone with the battery removed and wait. spFlashTool will tell you when it's done.
Unplug phone from computer (!) and put in the battery.
If you get an error "PMT changed for the ROM; it must be downloaded", reboot your machine.
When you have a running ROM on it, you may also try to keep the battery in the phone during flashing; just press Download on the PC, then select Shutdown in the Android menu that appears after holding Power pressed. Once the phone has shut down, it will vibrate shortly and then be detected by spFlashTool. I also recommend using a high-quality USB cable and not a worn out one because USB cables with worn out plugs may lead to issues during transmission.
NAND reflush?
Excellent stuff you wrote here - thank you.
Any hints on how to resurrect dead B15Q that has damaged/erased NAND or a Preloader?
In this link http: // forum . xda-developers . com/ showthread.php?t=1943442 a forum member
claims that mt65xx have META mode even if they appear dead - like mine B15Q is right now - and could be
revived with SPFT and proper W7 drivers.
Does under those circumstances PRELOADER might be reflashed?
I read just afterwards that one should not do fully ticked Memory Test as it silently reformats NAND.
I guess this is what happened in my case.
Also, a reason to do this test was that reflashing the phone with 1.010 BOOTIMG, ANDROID and RECOVERY, having it back for a brief moment and then upgrading it via OTA to 1.019 that had bricked it in a reboot loop.
Any clue would be welcome.

Bigal1337's image should also contain a preloader, but I guess in your total-dead state it'd be better to send in the device for warranty... after all no one can prove what exactly zeroed out your NAND.

It is all OK now and B15Q is alive and works well, as it did before the "big brick" Christmas blackout.
The main thing is that thanks to MTK low-level USB communication on chipset as is in B15Q makes it "unbrickable", really.
The other thing is my bad clicking around and "checking memory" while not really knowing what I am doing.
As well as Windows x64 drivers, admin rights and all the other voodoo lurking in there.
What troubles me more is how come that CAT ppl. allowed "bricking" device upon system update, while root or no root shouldn't really matter there?
They sell it unlocked, so they should sell it, as well, with an easy option to root it. As Nexus One from Google had this "build-in" option.
I still hope that future updates will not have the same behaviour and also that there will be an alternate option for some other flavour of Android.

I think I have found something... this chinese rooter apparently messed with internal symlinks, and the firmware update broke as it assumed "stock" contents...
Another reason not to trust rooters where one can't even read the description because its chinese...

I agree there. I gave up on rooting B15Q.
On the side note: lately I had 2 spontaneous reboots after this reflash and resurrect.
It happened after I used "official" messaging app more precisely after I send a message and close the app..
.
Did anyone noticed this? - it is 1022 I have up and running.
Other than that it works fine.
Hello,
I tried your workaround but haven't succeeded yet. And yes my phone also is bricked, unfortunately.
My phone halts where you have to choose a language after a factory reset. At that moment I get some messages that some services had stopped. Like Google keyboard, Youtube and some more. I can click OK but this doesn't get me passed these messages and they reappear. I only can switch off the phone.
I tried your workaround on a x64 machine (and got the PMT message) because that's what I have. I am preparing a x86 machine which has XP on it but on launching SP Flash Tools I get the message the configuration of the computer is not correct. Will W7 32-bits do the trick?
Also two more questions.
The downloaded images are : boot.img, recovery.img, system.img and uboot.img.
In your explanation you're mentioning : BOOTIMG, RECOVERY, ANDROID or USRDATA.
I presume that in SP Flash Tool I have to use the system.img in the row ANDROID?
Or should it be in the row USRDATA?
You don't use uboot.img. What's the reason for that? For what purpose is this image?
Update 19 april 2015.
I managed bringing back my phone to life. I did another attempt by rebooting my 64-bits computer (as you wrote in the beginning) because at that moment I didn't had a 32-bits machine. It worked wonderwell. So, I'm using my phone again. Like uhuru-meditation I give up rooting for the moment. Nevertheless Android 4.4.2 I still like this phone. Hope it won't let me down after this major reset. Keep fingers crossed.
harddisk_wp many thanks for your hard working in making this workaround. It sure has cost you more then an hour's work.
I hope you read my questions and can or will answer them.
CAT B15 help
Hi guys, i'm sorry i have to ask this in this forum but i've been asking for a couple of months now, and got no answer. I have a CAT B15 (not the B15Q). It is single sim version (IMEI write on the back) and i managed to do plenty of things in it. I swapped memory and worked fine, and even i installed a Dual Sim android rom and i managed to use the secondary Sim bay in it (that was tapped with a plastic fake sim) and used the phone with 2 sims for like 2 weeks. Then i started to play with deodex and build.prop and softbricked the phone, but it was piece of cake since it is easy to unbrick. The problem was that i wrongly flashed the phone with scatter file, and flashed all partitions in it, EBR1, MBR, UBOOT, etc, etc. The result was a non-working dual SIM phone. Everything works, but the SIMS, it does not detect any SIMs in it, in any of the SIM bays, and the IMEIs are wrong numbered. I did no buckup of the phone so i'm pretty screwed. I've been asking for someone to upload the EMEA_SS or US_SS ROM for the CAT B15, but nobody responded. I thaught maybe the CAT B15Q has a similar software/bands flashing partitions, but that i leave to you for answer. Anyway, if any of you has the possibility of taking the images of a single sim CAT B15 it would save me this awesome phone for me. I'm also willing to give a 20GB account of ownCloud server for 1-year free of charge if storage space is needed, no problem. This are the links i've been searching and asking.

2 Questions
Good day
I have the same questions as a previous user, but I cannot find any answer to it:
"Also two more questions.
The downloaded images are : boot.img, recovery.img, system.img and uboot.img.
In your explanation you're mentioning : BOOTIMG, RECOVERY, ANDROID or USRDATA.

Or should it be in the row USRDATA?
You don't use uboot.img. What's the reason for that? For what purpose is this image?"
Could you please help with these? Should I use uboot.img as well? And does system.img go to the Android row?
I added this 3d question later: is it safe to flash SS phone with the DS file?
Kind regards
"PMT changed for the ROM" and SP Flash Tool version
Hello,
I'd like to say big thanks and report that my B15Q was saved thanks to this thread, after a failed upgrade to the 1.016.00 firmware (due to the Chinese root app).
Moreover, I would like to point out that the procedure worked only with the v5.1352.01 version of SP Flash Tool. All other versions I've tried bailed out with the "PMT changed for the ROM; it must be downloaded" message. Unfortunately, the thread which is listed in the instructions refers to a version of SP Flash Tool more recent than v5.1352.01. A link to the said version can be found in this post: http://forum.xda-developers.com/showpost.php?p=58810386&postcount=4

Would you please care to share how you achieved that?
(Following some guide which said that upon ""PMT changed for the ROM..." error one should format the device before downloading, we did that (after reading back everything) but unfortunately, spFlashTool doesn't like the readback PRELOADER partition we extracted.)
goodnight I hope will help me have a cat b15q and remained in recovery mode and I need to flash it revive hope help me thank you .. I'm from Venezuela and one who does not get that software. Excuse my English but q use the translator
CAT B15Q - My Rear Camera doesn't work anymore
Good evening everyone.
After a bad update, my rear camera on CAT B15Q doesn't work anymore. I read all the posts here and I'm using Windows Vista Home Premium 32 bits. I downloaded all the necessary files and when I open the SP Flash Tool, I think it didn't recognize my smartphone and when I try to download any file to the phone the status bar on SPFT still stopped, like if anything is going on. I buy this B15Q on Paraguay. Could this fact be my problem? Anyone could help me, please???

Comprehensive guide on unbricking the ASUS transformer pad 103c (TF103C)

Welcome to the comprehensive guide on rooting and unbricking your precious TF103C!
Some words of wisdom and truth
You will most likely be here because, you know, your device is bricked.
First of all, I would like to say that none of the downloadable links are made by me. I happened to find them laying around XDA after looking for a solution for a long time.
Skip this if you don't want to know the reason behind this thread
I got this device a while back (my guess is 4 months), and loved it from the start. Rooted it, of course, and soon after, it didn't want to boot anymore.
As there isn't much development going on (due to the locked bootloader), it's hard to find a solution for bricking. While scrolling, I came upon a post from member gouster3, which came to the solution below. I myself have used this successfully, and have my tablet back. In my opinion, also on rooting, there was no dedicated thread available that really explained the steps to root the device, so as a thank you to the guys who got my tablet fixed, here it is!
The rooting process
The rooting of this tablet is quite easy, really! I'll explain in a few simple steps.
Head into settings > security > then turn on unknown sources
Download the Rootzenfone .apk file. get it here
Install the app (if it is still in your notification bar you can just press the downloaded file, or you can navigate to it's location to install from there)
Turn on airplane mode before you open the app
Open the app, and hit "OK, I know, please root!" (when you press this, a number of screens and a popup will show, ignore those)
5 seconds after pressing, restart your tablet.
Hooray! You are now rooted!
Unbricking your device
Luckily, unbricking is almost as easy as rooting the phone, if you know the steps you have to follow. Here's what you could do (it worked for me) if you still have acces to DROIDboot.
As always, install the adb drivers first! get it here
# You can also make sure the correct driver is installed when plugging in the device in DROIDboot mode. In you device manager it should show up as Android Debug Bridge#
Download these files, containing a clean system. get it here
Make sure the device is turned off, and the battery is at least 50% (just to ensure a complete flash before your battery runs out)
Hold volume+ and power untill the asus screen pops up, then release the power button.
Plug in the tablet to your pc (usb cable) when DROIDboot has been loaded.
Open the downloaded folder, and find 'update_image.bat'
Right click the .bat file, and choose 'run as administrator'
A CMD screen should open on your PC indicating the flashing status. All you have to do now (assuming that it works as intended) is wait untill the process is completed.
Your tablet will reboot automatically when the process is done.
That's it! the 2 things that keep this tablet alive. I would like to send a thanks to the members who were so kind to help me out on this.
gouster3, for providing the link to the unbrick solution
Eclipse00, for giving the link to the rootzenfone apk
Monki, for giving me a clean system.img and putting effort into getting my tablet running again
To all of you, thanks!
It works on my TF103CX too. (it is same hardware).
When i bricked my TF103CX, i had around 80% of battery, but i was not able to charge,
so be careful when bricking. Always do interventions to system with full battery.
//I think, we need add our TF103C to xda device list. it will be nice.
I heared that using Intel Manufacting Tool we can get UEFI instead of Droidboot, and boot Ubuntu/Windows on IntelBay tablets. I found guide for Teclast: http://forum.xda-developers.com/android/general/teclast-x98-air-3g-tablet-9-7-2048x1536-t2913035 But i cannot find any UEFI fot TF103C. I dont want to full brick m device with trying flash it.
Here is original thread in russian language.
Thanks
Thanks for helping me rescue my tablet. Much appreciated
Could anyone please confirm if the rooting method may be used on the TF103CG (K018) model? Or in general is the app able to root any device that is anyhow Zen-related?
this don´t work if you have lillipop on tf103c, the droidboot don´t load, You only get Fasboot starting and nothing more...
i want the raw lollipop image ( system.img ) for tf103c
will this essentially work as a factory reset? mine touch isn't working; and i just want to nuke all my data off the device
Hello all, I just ordered a TF0310C (Best Buy exclusive) from woot.com which will be here tomorrow and the closest thing I can find information on is the TF103C (both are Intel processors), and just trying to find as much info on it as I can. I was unable to find any roms or anything for the TF0310c, will things from the TF103C work on the TF0310C such as rooting or custom recovery at least?

Unbrick not working on tf103c running KK. It looked like it was doing something, but no luck. Any common troubleshooting tips?

I know its a bit late, but perhaps better than never. I'd say those devices are identical, but somehow there is a weird naming mixup. Here are the official ASUS pages for them:
http://www.asus.com/supportonly/ASUS Transformer Pad TF0310C/HelpDesk/
https://www.asus.com/Tablets/ASUS_Transformer_Pad_TF103C/specifications/
Whatever you do on the first link, it will be eventually redirected to somewhere that belongs to the second. Their specifications are also basically the same. This is still a guessing game tough, so the best would be to compare 2 build properties, partition tables etc. of those devices to know more.
Rooting will most likely work, Zenroot should do it regardless of device type.
hello,
i have tried different way to unbrick my tf103c, but none is working
i have access to fastboot
i successfully run your bat file to copy the image, but after it reboot and stays on the "asus" logo
if i launch the command after modified the name of the "AS-TF103C-v67.43-capsule.bin" into "capsule.bin", it reboot then a blue progress bar is showing, when the bar is complete the tab reboots, but again it stays on the "asus" logo :'(
do you have any advise ?
Same issue
Hello,
I have the same issue with my tf103c ; i was trying to apply a new update from asus support (to get android 5).
It didn't work and in addition to that, my device results to be bricked.
I have successfully run the bat file, but then i get stuck at Asus logo and device never boot...
Icarolo did you manage to solve your issue ? Is someone really succeed in unbrick tf103c device ?
Thank you in advance
Dead
Hi! I have an asus tf103c and i rooted it with the rootzenfone.apk but now it doesn't turn on at all. after i pressed okay, waited about 15 sec and then i restarted it, but it just turned off. And now it's dead. What should i do?
ASUS K010 (TF103C). I forgot how to enter Recovery
Hello everyone, I have an ASUS K010 (TF103C). The complete model is TF103C-MB1-BLK-DK.
I forgot how to enter Recovery. My Asus is bricked. I know it is possible to enter the recovery because a few months ago I entered and also enter droidboot mode. On that occasion I discovered pressing the buttons energy, volume +, volume - somehow, because I did not work the methods that were in different sites websites, but now I do not remember the exact way of pressing the buttons. I tried many methods but they do not work, only the "Asus looking for incredible" logo appears. The battery has a charge (I charge it manually).
If someone has this same model and knows how to enter the recovery would greatly appreciate it.:good:
I think you can enter the droidboot menu by pressing Volume Up + Power for several secondes.
i dont have acces to DROIDboot.
How can unbrick my tf103c.. thanks
