Hello,Hi again, Berni!
I just noticed on my other devices, which already run 18.1, that there it is not possible to spoof signatures, so microg is not able to work.
While on a third device, where 17.1 was running before together with Magisk, after sideload upgrad to 18.1 the recent configuration was still active and microg working, I wonder, if it is also that easy to just sideload 18.1 over 17.1. (here it is more critical because of lots of data and much work to reinstall everything manually in the case of failure).
According to another user:
dirty flashing over 17.1 is working. (I've never tried it before though.)OK, I've given this ROM another try (I dirty flashed the latest release over LOS 17.1) and I found out why I always faced frequent kernel panic reboots in all my previous attempts: presence of adoptable storage. Upon removing it, so far, so good! Thanks for your efforts, Bernie!
After flashing the 18.1 ROM, remember to reflash magisk before rebooting, in order to preserve Magisk environment.
For signature spoofing, just follow what you did on your previous device, so that microG could work.
