Ich have some issues with patch Android since some previous versions on android 7, 8 and now 8.1

I have two phones same issue in booth.

If try to enbale the android patch my phone restart but in lp its still unticked, also if i patch it several times.

Few times it worked until next firmware flash but there was the issue that remove android patch was not possible.

Seems that lp has any permission problems to change the patch.

If i use xposed to patch Android with lp, it shows a successful test result but i can't install different signatures over the installed one
