Hello! I am currently attempting to install LineageOS on my OnePlus 9 to start degoogling it.
The installation guide specified that I specifically need to be on Android 13 to install it, however I am currently running OxygenOS 14 with Android 14. Previous versions have had Open Beta threads for new OxygenOS versions which provided local rollback packages but I can't seem to find this for 14 to 13 for the life of me.
Has anyone else had this issue? How did you solve it? Any help is appreciated!
