Thats a shame - wish this device would get official support. From going through couple different cellphone models, and now couple tablets, the x606F has been the smoothest, best performance of UT that i have experienced.
Not sure where to put this, but here are the steps that I took to get Ubuntu Touch on the 606f
Required Files
- Download the latest artifacts for the project HERE
- Download Android 9 Roms files that were previously mentioned HERE
- Lenovo LMSA Software HERE
Steps
-
Using LMSA, i was able to downgrade to Android 9 by downloading the newest update for the 606f (Android 10) and replacing the files with the Android 9 Roms files within the directory and perform an "rescue" on the tablet. Once booted, Android 9 was installed.
-
Once Android 9 was installed, the usual procedure took place. Enable Developer Mode, unlock the bootloader reboot into Fastboot and flash the required files within the Artifacts folder.
OEM Unlock command : fastboot flashing unlock
I coudlnt get the SP Flash program to work correctly both in Windows and Linux and was surprised about the downgrade with LMSA.
