BTV-DL09 Back To Stock ROM

[Flavio]

I have sold my M3 (BTV-DL09, European LTE Version) and want to restore it back to factory. My ROM version is BTV-DL09C100B003.
I have installed TWRP and root and have also unlocked the bootloader.

What is the easiest way to achieve this?

BTW eRecovery gives me a "Getting package info failed" error message.

Well the hard part would be to find a stock rom to flash to so you can get back to stock. After you get there all you would do is just wipe data from TWRP and you should be fine.

But I'm not too sure as I haven't messed with the tablet as a whole yet, maybe someone can swing by~
