in device manager it says quadcomm hs-usb qdloader 9008. so by the looks of this it's a candidate for EDL mode .
i don't want to mess up anymore i think ill give this to a technician. gonna be a while is it ok to let the battery die.

If the bootloader is unlocked it should be fine.
Don’t worry about the battery, edl is very low power, battery can last weeks, and should still support charging

bootloader was unlocked before all of this happened, so does this mean i can use a android 10 back flash or use an android 11 one for avoid trouble again.

How can I UNBRICK a HARD-BRICKED OPX? Help needed urgently

I followed the instructions provided at the MEGA UNBRICK something thread situated here http://forum.xda-developers.com/oneplus-x/general/guide-mega-unbrick-guide-hard-bricked-t3272108/
Anyway, when I hold the volume-up button for 10 seconds, followed by plugging the Onyx with the PC, the system does't detect the device. What can I do now? And is there any alternative method to unbrick a hardbricked phone? I urgently need help
If you installed the drivers and the computer is not reckognizing the device, that's bad news. How did you manage to accomplish that?

I don't know. And ijust in case if you were being sarcastic, I used the same computer to replace the recovery of this phone.
Im not being sarcastic. The problem with the Android modding scene is that people got too used to blindly following steps without really knowing how they are affecting their devices. In order to get better chances at getting help, you'll need to describe what and exactly how you were altering your phone.

I was using Bliss ROM with BluSpark kernel. Anyway, I downloaded 2 ROMS today, Sailfish OS and the stock H2OS for OPX. I wiped the phone and first flashed the Sailfish OS, but the phone was stuck in a bootloop which only was showing the oneplus logo and the text "Powered by Anrdoid". After that, I entered recovery, and did the normal pre-flash wipe again. This time I flashed the H2OS, but after I gave "Reboot to System", my phone just wont do nor display anything. Hardbricked, dead
Can you boot it into recovery? Your bat may be dead from extensively flashing stuff, so plug the phone to the power cable and press and hold VolDown+Power for some good 30s, then you can conclude your phone wont boot into recovery and maybe need an unbrick.

Yeah, it didn't boot into recovery
Does the led light up when you plug the phone to the wall? If it does let it charge for an hour before attempting anything else.
After that and before trying anything else, make sure driver signature check is off and test mode is on. This varies slightly for Windows 7/8 vs 8.1/10. Which version are you running?

I turned off the signature check, W8
If your led doesnt light when your phone is plugged to the wall, this is behind the hard unbricking procedure and your phone is indeed, dead.

This issue has been resolved via PM,
Can a mod please close this thread?
No idea what it could be besides corrupt firmware which I've never heard of happening before. The Qualcomm utility should work just fine. Leave it plugged in for an hour or two and see if anything happens
Did you install the qualcomm drivers? If not do it again carefully with driver enforcement off. It works like a charm. Have bricked my device twice as of now and it worked.

[HELP] HARD BRICK (I think)

Hi guys!
I think I did something stupid while updating my XT1650-03 to Nougat.
What I did was manually flash stock nougat ROM (retbr) through fastboot, following the instructions within flashfile.xml, but, as I've read some bad things about the updated bootloader I stupidly decided not to flash it. The result is that it won't power up, even though I've tried: pressing power+vol. down; power; plugging the charger; fastboot commmands ( I was hoping it was just the screen that was off); to no avail.
I've noticed that when I plug the usb cable to the computer it plays that sound of connected devices.
Any suggestions? I'm probably going to have to take my device to authorised repair (off warranty, I know), but they usually take weeks to fix anything, so you guys are my best bet for now.
Thanks in advance!

Don't even bother going to the service center. The same happened with my device and they refused to give me the warranty. Motorola voids it the moment you get the unlock code. So my device was dead for 3 months. And I fixed it few days back. The good news is that your PC is detecting the device.
I will post the solution with a new thread in few minutes.

So, I'm totally lost.
As I posted in the thread above, even though Manish54 has been very kind to help, that solution did not work for me, so I've been trying to find another way. The thing is, this issue is beyond my comprehension. I'm not new to flashing and stuff, but I am new to moto Z. I understand that I should've been more careful and also have read a bit more before starting to mess with a new device, so feel free to judge me .
For instance, I don't know what fsg.mbm, adspso.bin, BTFM.bin and oem.img are for, since my old phone didn't have those (or at least I didn't need to mess with those), and I also don't know it they're relevant to my problem. If anyone could point me to some info on that, it'd be greatly helpfull.
Besides that, I've found mentions to tools like qualcomm's BoardDiag and QPST QFIL, but I'm not really sure if they apply for my situation, or even if I can manage to adapt the guides I've found to work on the Moto Z.
Any help is very much appreciated!
Thank you!

hello friends, I'm with hard brick on the moto z xt1650-3
due to an update via ota, when my bootloader was unlocked I was in the android oreo (8.0), however I went back to 7.0, due to an update via ota, the device did not call anymore, I tried several blankflash and nothing, I am very annoyed at this, thinking of dropping my hand, I took some assists nobody can solve, I hope someone here can help me, at least inform me something that is useful to recover my cell phone.
my cell phone is still recognized as "qualcomm hs-usb qdloader 9008 (com3)

Hey, my phone was dead two (brazilian xt1650-03), i spent three days struggling until i could bring him back. Thanks to the help in this forum. Your phone probably has the latest update opls27-76-51-7-july, so it must work:
first, you have to bankflash it with blankflash_OPL_27.76-51, its in the 30+ page topic tutorial here in this forum. Very important, must be in windows 7 or 8, with usb2.0
second, use this rom opls27-76-51-7-july-moto-z. it must work because its the last one. Its not brazilian, evething works fine but the netflix app didnt , but hey, at least our phone is alive again.
The secret is in the version of the firmware instaled before the brick, it must be the rom installed or latest to work

Help unbrick my galaxy tab 10.1 (GT-P7510)

hey guys new to this place, not that new, i've always search this forum for some rom or how to fix stuff and other help but never post anything here.
so lets get straight to the point. so basically i want to revive my old samsung galaxy tab 10.1. you know, for fun and nostalgia haha (if possible). so i don't really remember what i did to this tablet that it becomes like what it is today. cannot be turned on, no display when charging, no nothing. i do remember rooting it before. when it charge, there is a little warm going on on the tablet but nothing happen. when i connect it to my pc, it recognize it as unknown device the first time, and then i hold the power button for couple of second and my pc recognize it again but now as apx but no driver available. so i made a little research just now and i found that the tablet may have a chance to be fix with the use of nvflash or something. so all im saying is it really my tab can be fix without spending money? if can how do i do it? i have a little experience about flashing rom and recovery. but nothing on how to use nvflash. i do really appreciate your help to bring me back this tab that meant so much for me and my family back in the days.

You have 2 possible options
1. You can wait several days for the battery to die, then connect to a wall charger.
It may boot normally, this is the safest thing to try.
2. Use a blankflash there is one available for XT2061(burton) devices
https://mirrors.lolinet.com/firmware/moto/burton/blankflash/
download the blankflash, unzip it and
run the blank-flash.bat
If the blankflash works, the device will reboot, you may need to reflash firmware with fastboot or LMSA

Ok, that's info you should have shared first.
Letting the battery die won't help.
Your only option is blank flash, but no guarantee that it'll work.

Bricked my mi 10 5g after ota update.

Not sure how to proceed here. I had a very recent twrp installed, flashed a new ota firmware update as I have successfully a couple of times, phone restarted to twrp, I decrypted, it flashed the firmware fine then went to restart.
And that's it, completely dead, battery was at least 50% charged.
I can't enter recovery, power button held for one minute does nothing, vol+ and power, nothing, vol- and power, nothing, vol+ and vol- nothing.
Plugging in my charger, nothing, plugging into a laptop and pc, nothing. Took the back off and disconnected the battery and left it over night, nothing.
Bootloader was unlocked and usb debugging enabled.
Anyone have any other ideas what I can try here?
Also tried bridging the contacts for edl mode with battery disconnected and plugged it into USB but nothing.
Very tricky to do this though as you need 4 hands and it's possible I'm not making contact on both pins, purchased a cheap edl/deep flash cable as a last resort, if that doesn't work then I think it is toast.
Does your device have a file you’d an flash in edl (Eg. Firehose)?

From what I gathered you need to find a special “firehose” or like file that allows yout o flash it in edl. You seem to have gotten very very lucky because from a simple Google search, I found firehose files. They may or may not work.
https://support.hiunlock.com/index.php?a=downloads&b=file&id=1133 I found this, but I think it may cost money (I don’t want to make a acc, but from browsing the website, it seems it costs 20 dollars, which is a barbain for a device). You are lucky it exists at all though. I do not vouch for the file or site though. You should o research on how trusted it is.

Yeah, must have amde a small mistake, or ahd a corrupt file
“EDL is an interface of Qualcomm chipsets, used to flash fastboot ROMs. It is used for unbricking purposes so it is allowed on many phones but it's been locked down on most recent Android models.
The screen will appear black and it will appear that the device is turned off, but to verify that this is not the case, we need the tools in EDL mode. The most famous is QFIL (Qualcomm Flash Image Loader), a proprietary software, but on GitHub there are many alternative open source projects.”
