first of all you should not ask your questions in 2 thread and create a 3 one. Thats simple spam.Can I use the OOS11 zip I already have to downgrade from OOS12 using the other slot? It's broken several things. I've only found a method that wipes the phone so far. Or maybe just flash Magisk to the unused (should be OOS11 since I just "updated") and reboot back to it?
Maybe, maybe not. Better exposure as not everyone is likely watching the one or the other.
Maybe a fair point. Figured better exposure. Never can tell if the right person (with a solution) is watching the whole board.
Every Rollback Package i know will wipe your data.
OnePlus posted today on their forums the EU downgrade zip to 126.96.36.199 https://oxygenos.oneplus.net/OnePlus8ProOxygen_15.E.40_OTA_0400_all_2110091931_downgrade that you can use if you can't/don't want to use MSM tool , but you will need to add a .zip extension for it to be recognized by the OxygenOS 12 local update app.
YesJust downgraded from OS 12 to OOS188.8.131.52.INAA on a IN2020
Just to be very sure - if I wish to be updated to the latest OS 11 version, i should perform a local upgrade with the following file found under Signed flashable zips>IN11AA Global?

Afaik, global version dont have a full zip yet. If ur BL is unlocked you need the full zip.
Well the problem with downgrading is that u then don't have security updates...
