Yesss - I made it, really read most of the 54 browser pages of this thread

. I learned a lot and feel ready to try this out. Just a few questions:
- currently I'm running a different A11 based custom ROM. I plan to follow these steps from
@diemadedrei (
https://forum.xda-developers.com/t/rom-official-enchilada-11-lineageos-18-1.4174687/post-85600297). I guess I still have to format data partition before first boot into system? Or can I risk keeping \data as it is now?
- in regards to flashing updates: while I was still running stock OOS I always used this sequence:
1. d/l and install full OTA
2. from Magisk run TWRP A/B retention script
3. from Magisk run "install to inactive slot"
4. reboot
Is this still a valid concept with LOS 18.1? (yes, I'm fully aware that I *should* use LOS recovery instead of TWRP...)
- in my currently used ROM I don't have the "ADB As Root" switch in developer options; I already edited /system/build.props (added ro.debuggable=1) and rebooted, but still no switch. And no way to use "adb root", just receiving the "ADB root is disabled..." message. >> is this switch available in LOS?
Thanks for your tips
