Hello. I've got issues when installing this ROM on OP8 Pro, please help (or tell me where I did wrong).
View attachment 5414129

PS: when performing fastboot reboot, it always goes into recovery, and from there I need to to to bootloader by selecting it from the menu

PSS: a link or flow on how to revert this would also be very appreciated
You may need to first flash the latest OOS, and ensure fastboot driver is the latest version (you can use TOOL_ALL_IN_ONE.exe which auto-updates fastboot driver https://forum.xda-developers.com/t/...ck-twrp-factory-image-stock-recovery.3358711/)

Hello, I would like the return of some users. Is it possible to disable one of 2 SIM cards in the settings?

Back on my OnePlus 8 after giving the Pixel 6 a shot, and decided to hop back on this ROM. Quick question though. Are OnePlus settings still in this? The quick settings tiles are still there, and there is a menu item for it in settings, but attempting to open them just results in a force-close. Mainly just want to confirm.

EDIT: Disregard. Known issue, and there is an APK on TG to correct this.

    I suspect the other Havoc Features will come when its official.
    I agree if it stays same as PE then there is no point in having it

    Being as PE Plus isn't out, there is a lot more to Havoc. Both are great roms. There are differences, such as kernel. Each has its own optimizations. Everyone should be happy to have more choices for the OP 8 series.
