1st step was I made a TWRP backup when the device was pretty much stock (no root, standard recovery and kernel) and copied the files back to my PC.
Since then I have flashed custom recovery (TWRP) and Kernel (SleekAI)
Now if I enter Bootloader / Fastboot mode (Vol-Down + Power), would it be possible commands to return back to this state if for some reason TWRP recovery was no longer available and I wanted to restore back this image:
Check Tablet is visible in Fastboot mode:
Restore Backups using Fastboot:
fastboot flash recovery recovery.emmc.win
fastboot flash boot boot.emmc.win
fastboot flash system system.ext4.win
fastboot flash userdata data.ext4.win
fastboot erase cache
Also do we need to restore / flash userdata or could we just issue the following command to format (erase) the data and it would return to its original state?
fastboot format userdata
If someone can confirm that this would work it would be appreciated, also do you think the backup images from 1 device could be used on other v-510 devices? If so I could post them and this procedure for anyone else needed to use this to return to Stock.
Thank you for your help,
