Hi all!
@arubislander nice to hear, and to be clear, no irony needed. In a worse scenario nobody except a bunch of savvy developers would have tried using Ubuntu on that specific phone.
It is good to know that it actually can work in a friendly way as expected.
Unfortunately I have run into more problems since writing my last post here:
My "easy" 7 step dance course only works while running the android 9 version that is supposed to be prefered by the instalation program.
After that the installation program has flashed it's own version of boot.img using fastboot, the recovery i nowhere to be seen anymore. Neither with my seven step tango or by any other more traditional means. After consulting a few search engines without any luck I went the ai-chatbot way and got the suggestion that some android implementations keep the recovery code in the boot.img, if that is the case with the suggested android version, the instruction needs to be updated.
I am going to download a few other builds of android 9 from Google in hope that I may strike "gold", using one of them.
On my XL the recovery worked fine after flashing boot.img.
If that does not work, I will have to figure out whatever magic the install tool is using and then flash things in another order to get all the higher level stuff installed before I flash the boot-program.
If somebody could help me figuring out where the low level install procedure is documented (the one implemented by the user friendly installation program) and where I can download the installation files, then you will make me quite a happy man...
By the way, am I overly adventurous if I try the 24.04.2 nightly?
