2"What's disappointing is that these devices are the last to receive stable OOS12, despite their beta programs starting earlier than a lot of other devices... Hopefully this means there won't be too many bugs, but honestly we doubt it. This is OnePlus after all. "
https://oxygenupdater.com/article/352/1I received the updated on 10/31/2022 - my device model is HD1905_11.F.17 and located in USA. Not sure if I like OS12 - the Oxygen Launcher shelf is now replaced by Google Discussion unless I swipe-down from the top-right. WTH! Google Discussion is a waste and garbage chewing, with it disabled is a nasty looking screen that tells me to enable discussion... Not sure why OPPO pushed this particular change.1
If you're rooted Should just be
download full oos, disable or uninstall magisk modules, do local upgrade from system /system updates/gear.
Install magisk to inactive slot, reboot
Repeat process if you want 12 on both slots
If you're not rooted i don't believe you can force the update to both slots without flashing with ADB1
You can use ADB to find out which slot is booting then force boot into the other (not updated) slot and try the update again
Here are the rollback files and instructions if you want to go back to 11
