Hello,
This is meant to collect the steps I took, which worked, and which I distilled from various documents and sites, and much reading of this forum, in hopes it might help clear someone else’s mind a bit… (and maybe mine, later.)
There were almost no obstacles…
adb & fastboot were run on Macbook Air in MacOS14 using platform-tools-latest-darwin.zip
Enabling Developer Mode
In Android Settings.. System.. About..:
Quick taps on Build Number - OK
In System.. {Developer Options}:
Enabled OEM Unlocking - OK 1st try
(After reboot, 2nd try, option was greyed-out OFF… message appeared: “connect to WiFi or contact operator” - once connected to WiFi, 3rd try - OK)
Enabled USB debugging - OK
I also changed default USB mode to “File Transfer”
(probably superfluous)
The Hurdle
VolumeUp+Power did not boot device from OFF state to Fastboot Mode. Not my one, maybe others.
Unlocking Bootloader
On Macbook Air:
I unzipped platform tools zip file in a Desktop folder ‘tools’
Lenovo tablet ON and in Android
Connected USB-C to USB-C
In MacOS Terminal, as typed:
cd ~/tools/
./adb devices - OK
./adb reboot bootloader - OK
./fastboot flashing unlock_critical - OK
./fastboot reboot - OK - booted to Android
./adb devices - OK
Installation with UBPorts Installer 0.11.2
Lenovo device was recognised
I selected 'Ubuntu Touch'
Then 24.04… Stable
Also 'Erase User Data'
The installation jogged along until the tablet rebooted into Ubuntu Touch. I was not tempted to touch the tablet or the Mac. No.
No, not a bit. Anyways, don’t.
Ubuntu Touch booted its beautiful self!
An App Update was available, so I accepted that.
There was a request to allow the Mac to access an external storage (the tablet, must be) so I allowed that.
Ubuntu Touch home screen and gesture prompts.
Done.
I reported PASS for a successful result.
Now I’ll get started making it my own.
Regards,
KJU
[My first attempt with this device, after one former success with a Pixel 3a xl (bonito) and too much sad failure with a Nexus 7 (2013) (flo, or flox? with messed-up partitions…)]
