TNX

- power off device
- boot into fastboot (volume down + power on)
- select fastboot from on-screen menu, if not already there
- unlock bootloader: fastboot oem unlock-go
- after reboot, enter again fastboot
- enter command: fastboot erase config
- fastboot reboot

frp should be gone.

post results .... if not working, there is more dangerous method, by flashing FRP reset package.

i won't be able to unlock bootloader
FAILED (remote: oem unlock is not allowed)

but FRP removed by flashing using QFIL

thx bro !

First off, super helpful post Brka. This is the furthest I've gotten since I accidentally bricked my new Lenovo Tab 4 10 behind FRP. I was able to flash the FRP reset package to my Tab using the files you provided, but I'm still getting the message that the Tablet has been reset and I can't get past it.

I did receive a "Download Fail:FireHose Fail:FHLoader Fail: The system cannot find the file specified" error at the very end of the Flashing process with QFIL. There were no other errors in the flashing process though (e.g. Sahara).

I did notice something odd after flashing the package and then starting up the tablet. If I just click through "Next" through the choose Language and Network (it still remembers my WiFi after flashing) pages, then I get a black screen where I can't do anything except reboot it. But if I just tap the WiFi then tap cancel, it goes through the normal Checking process and tells me to sign into my Google account.

Is there something I'm doing wrong? Any help would be greatly appreciated.

Either you have windows/drivers issues or eMMC damaged.
Try on other PC, with Win7, for beginning.

So I have tried with another PC, but I'm still getting the same issue as before. Is there a specific driver I should be using? And are there specific settings in QFIL Configuration that I should have applied? Sorry, I'm very new to QFIL and flashing in general. Thanks for the help.

All needed (Drivers, flasher, etc.),can be found in stock rom archive.

Try to make it work first, then flash FRP reset package.

I got it to work! I had to download and install QPST 2.7 and flash using QFIL 2.7. The QFIL tool you provided wouldn't work on any of the PCs I used for some reason. In any case, thanks! I no longer have a paperweight!

Hello,

Dosen't worked for me:confused:
Any other solution??

tnx

Yes, solution is to read my posts in this thread - if needed, several times.
Posted solution works 100%, as tested and reported by members.
(If you have TB-X304F model.)

Tried the first mode, but to no avail. And with Qfil I am unable to flash, I get this error (see pic). https://imgur.com/a/g8n59bZ

- Read whole thread from beginning
- Read how others solved problems
- Put files in root of some folder on c:\ drive - ie : c:\x304frp
- Use win7/32bit for succesfull flashing or compatibility mode
- all problems arise of using Win7/64 or Win10.

I have managed to write the firmware still the account is ON.

Now download files from post #2.

- Flash it as regular firmware, via QPST (QFIL).
- After done, enter phone recovery, do "Wipe Data/Factory reset"
- Reboot device
- VOILA ! FRP should be gone.

In short: Usually means wrong drivers.

But i have TB-X304F ?

I finally got it to work.
But after that, I can not activate wifi?

Reflash device with ROM from post #7.

Check after flashing, does wifi turns on ?
Check settings / about device, does WiFi mac address exists ?
if it looks irregular - ie: 02:00:00:00:00:00 , then wifi ic has malfunctioned.

The WiFi mac address do not exist.
I haven't done Reflash because my qfile dont want to...

As already written, it will work only with correct drivers.

Clean/remove existing Qualcomm drivers, and install
Correct drivers in ROM archive from post #7.

ROM must be placed under root of c:\ drive (ie: c:\tab410 )

Preferrably win7/32bit, should work on Win7/64bit,
may also work on clean Win10.


p.s. WiFi / no mac address may be sign that somebody played before you with that device.
It may or may NOT be easy repairable, IF software problem at all.

Successful flashing
 

Hello,

I just got everything worked with the fellow steps:
1. I had a pc with windows 7 32bit. If you can,please make a clean install of windows 7 and full updates.
2. I downloaded the file from Brka at post #7. At the beginning it was not flashing but I used the first version of QFIL v1-0-0-2 and it flashed without any problem e.g Sahara or any other.
3. After finishing and rebooting, the device is still locked with FRP. Then you will have to do the same procedure but this time using the file again from Brka at post #2.
4. After flashing and rebooting, everything is perfect.

Thanks a lot to Brka

Thank you! The FRP Reset package worked for me. But instead of using QFIL from the package, I installed the latest version from QPST and used the QFIL from "program files/QPST/bin" folder.
First install the drivers from the FRP reset package.
In QFIL: select "Flat Build", then browse the programmer and flat build paths in the FRP folder of the FRP reset package (you should select a total of 3 files: 1 for programmer, 2 for flat build).
Turn off the tablet, hold both volume buttons, connect it to PC. In QFIL you'll see the QUALCOMM PORT. Press download, wait 10 seconds and it's DONE.
