hey guys.. so i decided to try PA Quartz 4 after a long time coming from OOS (Beta 16).. this is how i flashed PA
-Reboot to recovery from OOS (Partition A- Active Parition)
-Wipe Cache, Data
-Flash OOS OB16, TWRP 3.4.0.0, DM Verity Disabler
-Reboot to recovery (Partition B)
-Wipe Cache, Data
-Flash OOS OB16, TWRP 3.4.0.0, DM Verity Disabler (Something strange observed here, when OOS was flashed, there was a prompt in the script saying it is flashing A/B zip to Inactive Slot A)
-Reboot to recovery (Partition A)
-Wipe Cache, Data
-Flash PA, TWRP 3.4.0.0, DM Verity Disabler (Although in slot A, this time PA was flashed on inactive parition B)
-Reboot System
PA booted successfully, did initial setup
-Reboot to recovery (Rebooted to Parition B)
-Flash Magisk, DM Verity Disabler, Reboot, Profit!
I did not have to format storage with this method... Another query I have while I am exploring this amazing ROM.. I have been able to find 2 hidden features (Right Side Quick Pull Notification, Advanced Reboot).. could someone shed some light on what more hidden features are available in this?
