@deathmist I've been dealing with my broken screen for 3 months, you are my hero!
So,
I followed exactly your instructions. The new screen was functional as soon as I flashed all the images except the ones you told me not to. At the next reboot I flashed system with ubuntu.img and the result was an Ubuntu touch 20.04 with all my files and settings. Thank you!
Until now I have identified 2 problems
wifi is not working mobile data is not working as well (synchronizes to 2G only)@deathmist Please update this post in case any newer ubuntu images are released. Can you point me to the correct repo where I can open these two issues? ( unless there are already opened)
