It seems like there are a few people having trouble going back to stock and getting everything working.
As always, this requires an unlocked bootloader. If you don't have an unlocked bootloader then search google for a $5 service that does. It is what I did.
I flashed Project treble on my TA-1054. It worked great except it kept saying "insert SIM" when there was already a sim card inside, so I could not use it.
I tried to go back to stock but that firmware file on that google drive thread was corrupted, bad upload. Took me a few days to source this original firmware.
There is a tool called OST ( around 115MB), and a patch that comes with it (the smaller file less than 1MB)
The firmware is almost 2 GB
Download everything, including firmware.
1. Install the OST tool.
2. Replace the EXE file in the program files with the patch file you downloaded.
3. Delete the Onlineupdatetoolexe.config file. If you don't do this, the program will not start correctly.
4. Put phone into download mode ( either by powering it off, pluging into USB cable and immediately hold power and volume down. Or if you can boot into android with ADB debugging, just do a adb reboot bootloader.
5. Pick firmware file and click next.
THe first 2 times I tried this, It hanged at the last second. Third time was a charm. Give it time. Use a good USB cable.
I assume that this is the same way to flash other firmware files for other devices.
As soon as i get my hands on a android one firmware, I will flash it.
Or if anyone can guide me on how to extract the firmware on my TA-1045 USA version and flash it to my TA-1054 Chinese , let me know. Cheers.
