ALWAYS MAKE A NANDROID BACKUP FIRST!
Coming from another rom/clean install:
Reboot to recovery, flash required firmware
Wipe system, cache, dalvik/art cache, data
Flash rom zip and gapps
Updating from a previous build/dirty flash:
Wipe system, cache, dalvik/art cache in recovery
Flash rom zip, gapps and any other zips you may use
Never dirty flash from one rom to another
Builds are rootless, so to be rooted, flash your SU of choice
Substratum support is there as long as you have the latest Substratum app. You can now use Substratum on Pie with GZOSP/ Validus without root if you install this key apk:
Also enable "Force authorize every theme app" in developer options.
If you have Magisk installed, Substratum will still ask for root but will still work. This way you can use it with or without root.
Choose to build and update your chosen overlays, reboot, then enable in Manager section of Substratum app.
If you have any issues, grab a log after a clean flash, upload and link here please. Add steps to reproduce the issue in your post.
Do not report issues dirty flashing this over some unofficial build or with some kernel flashed.
Logcat Extreme app is great as you can choose to start recording a log just before reproducing an error and stop recording just after so you log just the part you need.
Xposed is not supported here, if you want to run it and have issues, try an Xposed thread for support and bug reports here only welcome with a clean install with no Xposed present.
Make sure to state which rom you are running when asking for support
GZR gapps, thanks to Janko Castvan
