17 April 2019 and newer updates

IMPORTANT: flash Magisk v19.0 (beta) or later only

CASE 1: If you're in latest lineage (Apr 12 or later): Follow normal flashing procedure (just remember Magisk 19.0+)

CASE 2: If you're on a ROM with repartition treble:

1. Flash the TWRP given below:

2. Reboot to recovery

3. Go to Advanced > Treble Manager and restore partition. (Take back your 1 GB space :p)

4. Reboot to recovery and Navigate (Wipe -> Format Data -> Enter yes)

5. Flash rom normally

CASE 3: If you're on non-treble old build/stock, I recommend clean flash

Just flash the TWRP above and install ROM normally.

Flash gapps & magisk 19+ if you are not wiping data.
