What I did was downloading the APKStudio application: https://github.com/vaibhavpandeyvpz/apkstudio
I then extracted the APKs with AMlogic Tools https://forum.xda-developers.com/and...tools-t3786991
So I extracted the NexBoxLauncher, and the SetupWizard apks from this ROM. Then I decompiled them (including the Java) with APKStudio.
Just to make sure everything was working I did not modify anything in the APKs, instead I built them, and signed them (with a keystore I generated).
Now I replaced them in the extracted ROM and rebuilt the ROM again.
And flashed the box.
When starting the box there is no launcher at all. So something is not working.
Is it possible that when I sign the APKs with a different keystore it won't work?
Does anybody have a suggestion for this?
Thank you very much.
