Hi,
recently my Nexus 7 got shutdown due to battery over,
and its appeared to be that when i am trying to turn it on it is getting stuck on the google logo stage,
so i have tried getting into recovery mode and doing a factory reset and wipe the device,
but, as soon as i am entering the recovery mode i am getting "booting failed" error and popped again to the boot menu.
i have also tried performing a flush using the SDK but i am unable to unlock the device, no matter how i am trying to.
i am getting an error saying "unlock failed (unknown error)".
So... have anyone encountered such problems and managed to fix it?
help me.. i am desperate
i was actually thinking why haven't i bought an I-pad.. but that thought passed right away
thanks in advance..

Return merchandise authorization

Can you give me an update what did you do with the tablet?
I also have this issue..
I found a way to get back the operating system but not sure if I should send it back for RMA or not..
I was able to unlock the bootloader via toolkit from there i installed the stock recovery to the system and finally was able to re-install the stock image..
Hi, I was trying to install cwm recovery from rom manager the tablet has rebooted and you are no longer on again, if I connect it to my pc is recognized as QHsusb load-d .. there is a way to bring it back to life? thanks
same problem
Just ran into the same problem running LagFix from the play store. :crying:
In principle, we would have to flash a new boot.img, but AFAIK that's impossible. On Monday I'm going to call and see if I can RMA it.
For anyone else who stumbles on this thread: DON'T RUN LAGFIX!
UPDATE 4/6 I sent it in to Lenovo. It's due back on Monday.

@enproceso94 Hi! Here's the link: inside the Lenovo.ru forum !

I am somewhat new at rooting, though I have rooted 3 phones. I was rooted on Android 4.4.2 and when I flashed a ROM for 5.0 my screen turned black. It won't turn on, I can't get into recovery or download mode, and when I connect it to my computer through USB it registers it as QHSUSB_BULK. I am stuck right now, is a JTAG the only way to fix it?

Does it charge or at least get warm? What ROM did you flash? Did you flash it via safestrap?
Can you access that bulk folder on your computer?

I don't know if it is charging and I flashed a rooted stock ROM for 5.0 (OA8) and it was via safestrap. How would I access the bulk folder, as it says driver is not installed?
A Verizon ROM? I thought you said a folder came up on your PC called something bulk.

It is not a folder, it detects my phone through usb as that. I don't know why, maybe I flashed the wrong ROM?
You were supposed to go back into download mode from safestrap and flash the OA8 kernel

After further investigation, the file I flashed was OA1, but the download said OA8. I should have been more careful. Is there anything I can do now?
It probably is a brick. Pull your your battery for at least 10 minutes and try again. Still not sure where it is saying bulk folder.

Okay, I will get back to you on that in around 15-20 minutes. And it does not have a bulk folder anywhere, what happens is an alert pops up on bottom of screen saying "driver not successfully installed" and when I click to check the driver it says QHSUSB_BULK where it should say Galaxy s5. Hopefully you understand, as I want to fix my phone.
Oh, under devices. This is probably a brick. Sorry.

Try charging it. If it doesn't even feel warm it is a hard brick.

Like you mentioned, JTAG. There are JTAG services out there. I actually bought a riff box because I bricked my s4 but I got my warranty company to give me a new phone so I never had to use it.

I have a verizon galaxy s5 I rooted it with the help and guidance from xda members over here. The method I used to root my phone was this one http://forum.xda-developers.com/veri...volte-t2879348 since i was already on NI2 I skipped steps 1. to 2.5 post rooting my phone everything was running pretty good for a few days without any issues but less than a day after I inserted a sim card in the phone it started randomly restarting so did a data wipe factory reset but the problem still persisted where my phone would would either randomly restart or go into a boot loop then I got the G900VVRU1ANI2_G900VVZW1ANI2_G900VVRU1ANI2_HOME.zip stock retail tar from here http://forum.xda-developers.com/show...42&postcount=1 and used ODIN to flash it but strangely even after I flashed the stock firmware it gave me the UNLOCKED logo at start below the Samsung galaxy S5 logo so I did another data wipe factory reset and now the UNLOCKED logo has gone but I'm getting a black screen after the Samsung galaxy logo. I can enter recovery mode and download mode my phone also gets detected in kies even with black screen.
I'm pretty freaked out and devastated right now because of the suddenness of this problem. I hope someone knows how to fix this issue.
Sorry for the long post but I wanted to be as detailed as possible.

OK I so I flashed this https://www.androidfilehost.com/?fid=23610159112652178 through ODIN as you said and now I am getting display after the Samsung galaxy s5 logo all the way to the main screen and although I was hoping that this would fix everything I was also kinda prepared if it didn't. So here are the issues I'm having now, the display is a little glitchy after the complete bootup and even a couple times in the recovery menu the phone is also rebooting automatically after it goes to sleep or if I press the power button to turn of the display and it then blacks out and reboots.
Thanks again for your help so far.

Did you buy it from Verizon? There should be a warranty of some sort from Samsung.
Also, does this problem persist even without the sim card?

So if I manage to get the receipt of the phone and it happens to be in warranty and I take it to a local samsung store do you think they will accept it even though it wasn't bought in USA?
Also do you think its a hardware issue or just a software issue as I have no display issues or any kind of other malfunctions when I'm in Download Mode.

Unknown about warranty but worth a try. I am assuming you are still stock NGC from your last flash. Maybe trying the latest lollipop would help. You need to root again. You can always go back to stock if it doesn't.

Hello...
Read this post: https://forum.xda-developers.com/showpost.php?p=71805763&postcount=343
If your device is in the state described in this post, it is likely dead. You need to RMA your device.
Otherwise if your issue is different, answer a few questions to help diagnose the issue:
What happened..?
What did you try to fix it?
What build are you currently on?
Is your bootloader unlocked?
Do you have access to recovery yet?
Good luck...
If you aren't in a boot loop of death you should be able to fix your phone by doing a factory reset. Power down your phone by holding down the power button. Go into the bootloader menu by pressing power and volume down at the same time. Use the volume keys to find the factory reset option and select it. Good luck. I'm pretty sure all of these phones will permanently boot loop at some point because there is a serious design flaw, probably with solder that can't withstand the heat the phone generates like on the LG phones. Hopefully your 6P isn't there yet but flashing an OTA frequently triggers it.

Hello... Did it start bootlooping after a 7.1.1 OTA? So you unlocked your.bootloader? If yes, it wiped all your data... And now your phone still bootloop right?
Then reboot into recovery, press power and tap volume up when you see the Android guy laying.
From the menu, select factory reset. Try to reboot and see.if that helps.
If it still doesn't work, try to flash a stock firmware from here: https://developers.google.com/android/images#angler
And extract the zip a d open the folder
Reboot into bootloader. From here, openn the flash-all.bat and let it install the new firmware. It will reboot when it's done flashing.
Hopefully a factory reset will suffice to solve the issue. Let us know if it works... :good:

Hello...
Sorry to read that. Only way now seems to have your phone repaired. I don't know if you're still covered, but don't let Google or Huawei charge you if your warranty is already ended. The issue is well known and you shouldn't pay for their mistakes!
If you don't get a positive answer from the first person, tell him/her you are going to think about it and end the call. Call back one or two days later. You'll likely speak to another tech. Retry as much as needed. A lot of people who insisted have had their phone repaired/replaced for free that way. Try escalating the case to a supervisor if needed. Don't give up until you succeed, because that's all they are waiting for!
Sorry again, good luck...
My phone is out of warranty
I buy in portable form
And I'm in Vietnam, so Warranty is almost impossible

Buy a Processor for example ?

I've seen someone saying some people send their device in China to have their SOC/processor replaced. You know those are soldered on the motherboard right? Unless you have the right equipments, it's really unlikely.
