@MrT10001 I flashed this https://gitlab.com/ubports/porting/community-ports/android9/lenovo-tab-m10-fhd-plus/lenovo-x606 which said it supports TB-X606X (X606F/X606FA/X606X/X606XA), though it is not an official port.

@MrT10001
Hello. I got a device named TB-X606X and I flashed the Android 9 image. It boots into the system but the touch was strange. I unlocked the bootloader and checked the boot again. And then I flashed the boot and system and format the userdata into ext4. And then when I reboot, it didnt display anything and boootlooped. I think I need your help. Though I can make it back to use, I still want to use the Ubuntu port. Thanks.

@luksus There is people in Chinese successfully flashed the ROM, just checked.
I have lost interest in it. However, I hope that untick the Preloader part will work.

@luksus I have tried, but this list of build is not working. I flashed the earliest build of TB-X606F, but my tablet still loops on the Lenovo screen and red light. I wondered what had the 'Erase All' done, and whether it brick my tablet forever. Another possible thinking is my tablet is a Chinese-version one, so the rom is all wrong to me.

@luksus Hello bro, I have trouble downgrading my tablet. It is TB-X616M, which is similar to TB-X606X. I 'Erase all' it by accident and I need a rom of TB-X606F_USR_S100168_200828_BMP, but I cannot get it. Can you send me one on mega or other drive? Thanq very much.
