Looking for testers: port for Lenovo Tab M8 HD (TB-8505F)
-
A reboot fixed it. Weird
-
@MrT10001 That is possible. Before turning to UT I tried to port LineageOS 17 for the tablet. In my notes for that I have
fastboot --disable-verification flash vbmeta vbmeta.imgusing the
vbmeta.imgfrom the stock rom (downloaded with the Lenovo Rescue and Smart Assistant). -
@Lesharoturbo No. I am still working on this port. I think to be able to receive OTA the port must be an official commuinty port. For that I still have to fix some bugs.
-
@Lesharoturbo No idea. The artefacts are build with Focal, and I never noted missing letters. However, when building for Noble I see a couple of missing characters. I do not have EGL fully working, this could be the cause.
-
@k.nacke thanks for your hard work.
-
Looking at the specs for this tablet gets me somewhat curious, if you manage to get this tablet port into a functional state (fingers crossed) would you consider porting the different variations the Lenovo series of tablets such as my own M10 2nd generation tablet 2gb 32gb version (Which can run UT after installing android 11 apparently) or the m11 tb-330.
-
@voodoojaza My plan is to finish the port of the Tab M8 HD, and then try the Tab M8 FHD. I own both tablets, and my main motivation is that with Ubuntu Touch the tablets seem usable. At least the UI reacts fast.
Android is a pain on those devices.
Porting without the hardware is not possible, and while I think that it should be easier to get a port for the M8 3rd gen and M8 4th gen after finishing the current port I am not sure that I am willing to spend money for such low end devices.With the existing ports for the M10 it should be possible to get the other M10 models working rather fast. I looked into the M11 because that tablet is somewhat similar to the M8, however Lenovo did not publish the kernel sources for it. So yeah, not really motivated for that.
-
@k.nacke Thats great, thats what I thought, something to try when I get time. Keep up the good work.
-
Is there a recovery image yet or is the RAM size creating limitations?
-
@k.nacke That worked. My 8505F is now running UT, albeit slowly, but better than Android.
Steps to reiterate (Using Windows 11 -
)- Unlock bootloader = ./fastboot flashing unlock
Reboot into Android, set it up etc.
- ./fastboot flash boot boot.img
- ./fastboot --disable-verification flash vbmeta vbmeta.img
("using the vbmeta.img from the stock rom (downloaded with the Lenovo Rescue and Smart Assistant).")
- ./fastboot flash system ubuntu.img
- ./fastboot flash dtbo dtbo.img (don't know if this is necessary)
- ./fastboot -w (It will error here, ignore).
- ./fastboot reboot
-
@MrT10001 Thanks! That is great news!
./fastboot -w (It will error here, ignore).That error should go away when you
cdinto the directory with the stock rom files first. -
@k.nacke I will try that next time as I have acquired another one. Can I add the above to the readme on your Gitlab so any one else who is interested can follow it? (I tried but it forks, so I left it and thought I had better ask). Great work on this one. I am playing with scaling as it was scaled at 16 and I thought that was scrambling text, but even at 12 some text is missing (using the Tweak tool).
-
@MrT10001 I added you as developer to the repository. Feel free to change the readme.
-
@k.nacke Readme updated and awaiting merge.

This is one area for which I really need feedback. This is not only my first port, it is the first time I see Ubuntu Touch on a real device.
E.g. the icons may be too large.... -
@k.nacke I also had a scaling issue and set it to 12.
The nursing chargers were fixed by reviewing. I have not had that issue since.
-
@k.nacke It seems ok after a reboot.

Missing characters
