S1642788415706 , via OnePlus 9R , May 20, 2022 : Hai, I am currently using the OnePlus 9r Device with the most updated version of Oxygen OS 12. I got a March security update.It is possible that I can reboot the OS 11
Swejuggalo , May 20, 2022 : Going back will wipe your phone completely. On C17? Since you get a full wipe anyway... Why not try a factory reset and manually just copy important files and do a clean setup first? It may solve several issues. If it does you still keep updated security instead of forever being out of date. However if you still want to rollback you can use the instructions existing in Open beta 1 for 9R.
