Has anyone any idea on how to get out of this situation. Device totally unresponsive, screen is black blank and displays nothing irrespective of button press combinations, including EDL. Not that its of any consequence now but this was achieved by my flashing a data file onto and overwriting the "aboot protected partition"
Device cannot be switched "on" and therefore is not recognized by windows device manager. Windows has all drivers installed i.e. ZTE - Qualcomm - Qualcomm EDL, although this is rather a moot point considering the device won't switch on.
The following files are still alive both on my device external SD card and in a windows "C:" folder --- B20 file, B27 file, B29 file, B15 file, plus a TWRP backup. To repeat myself all and every button combination has been used to no effect.
I rather much doubt that I shall get an answer to this question but has anyone any idea as to how I can get in the position where I can flash any of the above files?
Attempt to put it in edl mode I believe there is an unbrick guide somewhere around here. Aboot is related to bootloader so your phone is bricked.
Do you hear any sound from the PC when you connect the phone? This is particularly important because with the "wrong" driver enabled your device may not show in Device Manager, but it most likely, may have booted into EDL mode. Please check this and post back. If there's a sound on connect, there is hope. Nothing ZaDig and the new unbrick guide can't help you fix. I was in a similar hopeless situation a few weeks back but I resolved it with the help of the unbrick guide.
@george241312 ... @KwesiJnr ... I appreciate your answers and thank you for bothering to reply.
george ... Sad to say I was fully aware of what I was doing when I overwrote the "aboot" partition and anticipated ending up in something like my present situation. I have one final line of help to try before giving up all together.
Kwesi ... The only sound my device made was agonizing screams as I totally bricked it.
THANK YOU ALL BUT NO MORE REPLIES IF YOU PLEASE - CONSIDER THIS MATTER CLOSED ..... The device is dead due to my own stupidity and I will just live with that.
Try connecting the phone to another computer or wall charger ?
Hey guys, I have a A2017 axon 7, and I tried to upgrade from Marshmalow to nougat by flashing the B04 update from TWRP. I have now the factory recovery mode, and when I try to go in fastboot, it tries to launch the bootloader( which just tells me that my device software cannot be checked for corruption and that I need to lock my bootloader). When I try to boot normally it stays on the same "bootloader screen" and tells me to press the start button which makes the phone display the linux logo.... I'm a bit lost, I'm on ArchLinux could you pls help me ?
Thx !

Well, you should use MiFlash and install the stock system through EDL. The problem is that MiFlash is for Windows x64. if you could get a win10 x64 pc, you could fix it in a minute.
Or get to the recovery if you can, and flash Nougat again but via an SD card. But maybe you won't be able to get to the recovery mode

I need help! I wanted to relock the bootloader but then I coulnd't enter the recovery or fastboot anymore. When I press any combination it always turn on for 1 sec and then the screen turns off again but it still GOT recognized as QUSB Bulk. After I installed MiFlash the device is recognized as QDLOADER 9008. I didn't flash anything and I don't kno how to unbrick my device now .
I use the A2017G model btw.

How did you relock the bootloader? If you used a guide, you should have found a warning, and if you used axon7toolkit a message should've popped up.
You messed up. Real bad. You are probably on DFU mode, and the only ways to get out of there are:
-discharge the battery completely and try to enter FTM mode (i think you have to do that while it is connected to a PC), I think it was with volume down + power. this method works for very few people. If you enter ftm mode, issue 'adb reboot edl' and use MiFlash right away with a FULL_EDL package
-use the 4th category brick repair manual (disassemble the phone, short some pins)

I think DFU Mode is when I get recognized as ZTE Handset diagnostic .... according to this guide : https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898) It's a2017 but still.
"Axon 7 restore manual from bricked conditions when only ZTE Handset Diagnostic Interface(DFU) (COM...) mode is detected"
But I get recognized as QDloader 9008 and miflash also recognizes it as com10 or something.

it's not necessarily like that. DFU mode is just a mode in which the phone can be. Sometimes Windows just installs the QDLoader driver even though it's not EDL. and if you tried miflash and it didn't work, then it's most probably that.
There's a way to check. If you go to Properties, there should be a number that identifies the mode. if you google it and 'dfu interface' appears, then you are dfu-bricked
But if you locked the bootloader without being fully stock then it's most probably dfu bricked anyways
Again, how did you lock the bootloader?
I don't actually know if I really locked the bottloader.
So, I had unlocked bootloader and twrp. I just bootet into the bootloader, typed "fastboot oem lock" in adb and it said OK on the PC.
But on the phone it never asked me if I want to lock it or anything. And I never said MiFlash isn't working. It recognizes my phone but i judt didn't TRY to flash anything because I didn't want to make the situation even worse perhaps

Lol it doesn't ask you if you want to lock it, that's the point with bootloader mode. there's no system, no UI, and you make stuff via commands.
This is why you shouldn't even attempt this kind of stuff without knowing how it works. At least if you had used axon7toolkit, it would've told you not to.
Find a FULL_EDL package for your model. If you have an A2017, simply use this one:
https://androidfilehost.com/?fid=817550096634790942
or
https://mega.nz/#!JqwEUDCa!lW3NDaBNbmMxhtw6XajspHBJaaEmLC8uNvMZS5ww0EQ
(they are the same file)
Unzip it, leave the folder somewhere handy, put the phone in what you believe is EDL, open MiFlash and select the folder, and flash

Okay let me tell you this real straight. I have done this. I have the G packages, I just thought you were the op for some reason. Look at the back of the phone and confirm whether you have an A2017G or an A2017 just in case, or you might mess up even more, as hard as that can be.
at any rate, your fears are all dumbfounded, because in the situation that you are in, you have 3 options:
a) disregard all the help that i'm trying to give you, even though I have already done the process; and keep your brick on a shelf.
b) search on google or xda yourself, then do the process, without bothering here with your lack of trust
c) follow my advice and do the damn process
Whichever option you choose, I'm gonna leave the package here:

or

Again, I HAVE FOLLOWED THE 4TH CATEGORY BRICK REPAIR GUIDE AND FIXED MY G. I flashed stuff through EDL at least 10 times. And there wouldn't be a bunch of EDL packages for the G if they had a 100% chance of bricking your phone
So. If you decide to do this, turn your phone off. connect the USB cable to the PC but not the phone. Hold both volume buttons (but not the power button) and insert the USB cable at the same time. Then fire up MiFlash and try to flash the file (you have to unzip the folder, then select the folder on miflash, then flash. Here 2 things may happen:
a) it flashes and you can just go bother someone else
b) it doesn't and you have to follow the 4th category brick repair guide
Simple as that. if it fails, you might want to check if the 'Qualcomm HS-USB QDLoader 9008' is actually EDL mode or DFU mode, so you can do that by going to properties and checking some device identifier number on google (haven't done that, i just read that it can be done somewhere here).

THANKS SO MUCH , you saved my ass, it flashed without a problem and sorry for bothering you. Bootloader is locked now and it works fine. Thanks again!

Hi,
A2017G
Started with marshmallow,
Unlocked bootloader
attempted to install Slim7
seemed to work but with some possible errors, (wouldn't sync with google... retrospect I should have looked elsewhere before...)
attempted in install stock rom
using
ZTE_A2017GV1.2.0B04_BootStack_by_tron1.zip
ZTE_A2017GV1.2.0B04_Stock_System_by_tron1.zip
which wouldn't boot
So I tried reinstall Slim7
then stock again,
then, like the noob that I am, I removed twrp with
ZTE_A2017GV1.2.0B04_Full_Stock_Reverter_by_tron1.zip
which installs stock recovery
so, now I have a stock rom that won't boot,
an unlocked bootloader
and stock recovery
Not sure what to do from here
thanks in advance for any assistance.
I can abd sideload and update from SD card, but everything I have fails signature verification.
edit: so frustrating trying to find that 1 zip

Just use MiFlash, that one's guaranteed to work. Read my DFU unbrick guide to know how to use it. Just skip the part where you have to disassemble the phone, since you can get to EDL mode by (with the phone off and the USB cable connected to the PC) holding both volume buttons and inserting the USB-C cable to the phone.
I did read your guide, was, hoping to avoid dismantling it...
I tried pressing all 3 buttons.
Am I understanding the procedure correctly:
[phone switched off] + usb-C cable connected to PC only
MiFlash running at this point??
Hold both volume keys in and in insert Cable to Phone
at this point is the phone supposed to switch on?
At no point am I supposed to press the power button?
fyi: I will try different combinations, is great to have a solution, thank you.
Ah.... ok... so, the phone will display nothing, rely on the sound of PC and/or the device manager check and/or hit refresh on miflash
Fyi to anyone, if you have axon7toolkit installed and thus can't install a second version of MiFlash, open up the toolkit and hit 7 (unlock bootloader) to fire up MiFlash... or just go to C:\XiaoMi\XiaoMiFlash
the FULL_EDL file I have produces a couldn't find script Error when loading into MiFlash
so far when attempting to flash all zips
I have started MiFlash with admin
unzipped FULL_EDL file to a folder in root C:\ and ensured there are no spaces in address.
Every time / Every file produces couldn't find script error when loaded into MiFlash
when I attempt to flash the file it says cannot receive hello packet and then times out with an error
Tried disabling anti-virus/firewall, still same error
upgraded MiFlash to 2017.4.24.0 ( older 2016 is included with axon7toolkit), this removes the couldn't find script error, but still not receiving a hello packet, gunna fiddle with the phone as I'm pretty sure the error is coming from there
YES!
rebooted phone, turned off, restarted into EDL, flashed the stock rom from zte site... is in chinese... but it works. Thank you Thank you
so adventure over, after all that I am back to 6.0.1...

I got it from here: http://www.ztedevice.com/support
selected:- United Kingdom > Mobile Phone > Axon 7
it offers a file "AXON 7(ZTE A2017G) SD card software package(328540B2634ZTE A2017GV1.0.0B11)"
which hints at being compatible with A2017G... but is A2017V and is chinese, although you can change the language in settings there is still plenty here and there, plus chinese bloatware
and No, I didn't get cell signal.
I've gone back to Marshmellow, I will try again, didn't think it would be so different/difficult... Although wow at MiFlash.
FFS!!!! Relocked bootloader and bricked it!!! there should be a warning!
you gotta laugh,
I am a bit livid, I know the guides come with disclaimers, however, you'd think it would be an obvious important warning to make... DO NOT RELOCK YOUR PHONE.
FFS!

Hi,
It looks my tablet got hardbricked. Apparently, it looks like it was turned off completely automatically, when in sleep mode. When it's powered off now - pressing power button for a while makes nothing. When connected to charger - white LED flash is blinking only and when trying to power on, and there is no "Lenovo" logo at all. I've tried some of "power cycle" tutorials - but no luck. Once, when using power button, tablet was vibrating crazily and screen blinked, but it was shut down after moment.
Sorry, if there is existing similar thread - this tablet is not very popular. If there is any "magic trick" to make it work, I'll be grateful, if now - probably I'll need to flash new firmware. Currently, I'm discharging it completely.
Best regards.

Are you still bricked? There is the firmware flashing method using SP Flash Tool which restores both the 850F & 850M to full factory condition. Let me know if you need the method and I'll get you links to the guides here on XDA.

Yes. I've asked for help guy from unauthorized repair service, he said device is completely bricked, probably EEPROM chip is broken. But ok, you can send me this instruction of course

I've had two 850F devices hard bricked and was able to recover using SP Flash Tool and a stock firmware package. I'll get you the method posted here. But, out of curiosity, how did you hard brick yours?
(The 850F is pretty much an 850M without SIM/data connectivity support. They also have slightly different chipsets, but many of the specs are very similar. So, I know the method will work on both variants of the Tab3 8.

Hey, thanks for you reply! As I'm not owner of the tablet, it's hard to say how it was bricked. It was on stock firmware, it was not rooted and TWRP was not installed. I've helped to configure this tablet, tablet was turned off everyday at 11PM automatically, and powered on manually, by device owner. She said sometimes instead of powering on to Android, it was booting into FASTBOOT mode (green android image). Once, it just failed to boot, without any reaction. I've tried to recover it using Windows machine, when plugging it into computer (no matter, with, or without Vol+ pressed) it was recognized as Unknown device (instead of Qualcomm, or something). I've tried many drivers - but with no luck, device was not recognized. Also, I've tried 2 machines with Win7 & Windows XP. I've managed to reboot device using power key long pressed, but starting from this point device was not recognized at all... When plugged into USB, nothing was happening. Service guy said he was able to make his computer recognize device using some technical cable plugged directly with motherboard, but all methods to flash firmware failed. He said probably EEPROM chip is broken completely and replacing this part is half of device cost. Thing is, this tablet was bought from China - so no guarantee at all. Well, probably she need to buy next tablet from local electronic store...

I've helped to configure this tablet, tablet was turned off everyday at 11PM automatically, and powered on manually, by device owner. She said sometimes instead of powering on to Android, it was booting into FASTBOOT mode (green android image). Once, it just failed to boot, without any reaction. I've tried to recover it using Windows machine, when plugging it into computer (no matter, with, or without Vol+ pressed) it was recognized as Unknown device (instead of Qualcomm, or something). I've tried many drivers - but with no luck, device was not recognized. Also, I've tried 2 machines with Win7 & Windows XP. I've managed to reboot device using power key long pressed, but starting from this point device was not recognized at all... When plugged into USB, nothing was happening. Service guy said he was able to make his computer recognize device using some technical cable plugged directly with motherboard, but all methods to flash firmware failed. He said probably EEPROM chip is broken completely and replacing this part is half of device cost. Thing is, this tablet was bought from China - so no guarantee at all. Well, probably she need to buy next tablet from local electronic store...

Yeah, the service guy is full of it without any doubt. Using a modded fastboot cable, like he was likely referring to, will not only fail to push firmware to the eMMC, but will very likely damage or corrupt the partition index. I can't promise my method will work, but I can say with some certainty that it will. Ok, first things firstt: install the latest SP Flash Tool on your Windows PC or laptop. Also, you will need to install the latest vCOM drivers (for the Mediatek chipset). Do you know how to do this or do you need links? I can post a link for unbricking the 850F, which has been reported to work on 850M, but the thread is a bit erratic and non-concise. It will be much easier if you and I do this step by step. Also, you will need a stock firmware package for your 850M (build version is not relevant). Do you have one or do you need a link?
In a nutshell, this method will do an emergency recovery by directly pushing a stock firmware package to the device's eMMC flash memory. Although your PC is not currently recognizing your device, the vCOM drivers/SP Flash Tool, & your volume down button, will force recognition of the Mediatek chipset. Again, I cannot promise this will be successful, but I can say I've not yet seen a single hard bricked Tab 3 that could not be recovered from a hard brick this way.
Step 1 -- install the latest vCom drivers on your Windows (7, 8.1, or 10) PC/laptop. Here is an excellent XDA tutorial that provides sources and detailed instructions. https://forum-xda--developers-com.c...-10-mtk-vcom-usb-drivers-32-64-t3267033/page1 Sorry for the lengthy url.
Step 2 -- install the latest SP Flash Tool on your PC or laptop. Go to this website for download sources; https://spflashtool.com/
Step 3 -- download a stock firmware package for your TB3-850M. This is a link for a solid firmware package, confirmed to work (take note that build version isn't a factor. The SP Flash Tool will push a downgrade, upgrade, or collateral installation {same build version}): https://cloud.mail.ru/public/LHhe/NkpAi7WuL
When you've completed the above 3 steps, let me know and we will go forward with the firmware recovery process. :good:
I have the same issue. I dont know how but i got hard bricked completely. I was flashing rom on it and it got bricked. Now service centre guy is saying that i have to change motherboard altogether. But your post seems convincing. Please let me know the next detailed process.
i have the same issue.
one day stop working

what is next? i have a tab 3 710f that is very dead.. hardbricked in wont boot into nothing.. black screen like its shut down
I have a Tmobile OnePlus 6T, hard bricked.
Mine gives the usb device malfunctioned error. I have installed, uninstalled and reinstalled the qualcomm usb drivers. It recognizes the phone in the device manager as USB DEVICE DESCRIPTION FAILED. The MSM tool wont recognize it, and my phone wont boot in any other mode except EDL. It will not boot to bootloader or anything. Funny thing is, all I was trying to do was convert the T-Mobile version to international which I've done before. During that process, it hung at "recording downloading time". I let it go for 20 minutes, according to the guide it is supposed to take 5. I canceled the process, (I had done this one other time before, and it booted just fine) and now nothing works. I am not a noob at this. I can restore through fastboot if I could get it to boot into fastboot. I could restore through recovery via sideload if I could get it to boot into recovery. Please help.
*Moderators, I have searched high and low through the forums and I cannot find a thread with this problem that has any steps to solve it. I found one thread with a similar description but it is a year old, has no replies and the author managed to fix his phone on his own, with no description of how he did so.*

The other of the previous post probably figured out how to get the device recognized by the computer. I would say see if you can use another computer/cable and see if it still has the same issue, if it does i'd probably be concerned about the device health. If the issue is gone on the other PC though then you likely have something wrong with either drivers or usb hardware on your PC. I would assume you've already tried using a different USB cable and port with your current PC.
