@zedr0k You mean right after fastboot flash system ./ubuntu.img?

@kugiigi I use arch linux, and the fastboot is the correct version as mentioned in the readme. Confirmed with ./fastboot --version. I also tried it with my sdk installed fastboot (v35), with the same results.

I'm trying it with the official UBPorts installer now, and sse if I have success there. But the downloads there are very slow at ~80kbps, so it probably need a couple more hours until I can test it.

Hi all,

I have an X306FA and as there is no Android 11 firmware for this model available I took the risk and flashed TB_X306F_S230626_230530_BMP (since A only seem to stand for Alexa).

It was a success and I confirmed I could boot into Android 11.

I then followed the instructions from https://gitlab.com/ubports/porting/community-ports/android11/lenovo-tab-m10-hd/lenovo-m10-hd

It worked all well until fastboot format:ext4 userdata:

Warning: userdata type is raw, but ext4 was requested for formatting.
FAILED (remote: 'Could not open partition')
fastboot: error: Command failed

This seems to be weird, since the partition is available fastboot getvar all:

(bootloader) partition-type:userdata:raw
(bootloader) has-slot:userdata:no
(bootloader) is-logical:userdata:no

(There doesn't seem to be a size entry tho)

Erase also not working:

Erasing 'userdata'
FAILED (remote: 'Partition doesn't exist')

I then went into the recovery and did a factory reset for data and system. No change. I then decided to flash the userdata again with fastboot since I thought maybe the inital boot to android changed something but I there is no change. I took the firmware from the github repo: https://github.com/rubencarneiro/amar_row_wifi/releases

I confirmed I use the recommended fastboot version:
fastboot version 30.0.0-6374843

Now I do not have any ideas left...
