I am trying to install UBport to a samsung S7 which currently runs /e/ with android 10.

On my Win11 laptop, the UBport installer detected the phone correctly, download the 2 .img files. Then I reboot the phone to "download" and UBport does not detect anymore my device. I tried also the reboot to "recovery" and "recovery with ADB", same issue.

On my second laptop (armbian arm64), with the phone state "recovery with ADB" is detected by the adb command as "sideload" (if I remember correclty).

I think it is easier to try the UBport installer first. Do I need additionnal software on my Win11 laptop to run UBport installer?

Otherwise, since I have the 2 img files and an adb running, where can I find the doc for the manual install ?

Eventually, once UBport installed I don't need a fully functionnal phone. I intend to try to convert it as low power, low cost home server...since there is a raspberry shortage.
