I've just been through a firmware update of my Philips Android TV today, including reinstalling the TV from fresh after upgrade.
Because of the hassle in reinstalling the TV from scratch, I decided to make some Linux BASH scripts to help with backing up specific APK and their data; reinstalling each APK and its data; and removal of individual bloatware apps; all via ADB.
If anyone is interested the code can be found here : https://github.com/kaipee/android-backup-removal
congrats on the work kaipee.
a while ago I was using a GUI for installing and uninstalling apps, although I ended up using adb as CLI was faster.
I think it was https://forum.xda-developers.com/t/tool-adb-gui-also-flashes-radios-08-01-11.666964/
although the project seems outdated now.
I suggest to look and see whether there is a generic ADB GUI tool out there, and if not, it'd be a good progression for this.
