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!

Almost, this seems to contain the rollback from Android 13 to Android 12. I cant find any article about rolling back 14 to 13.

Doesn't the Lineage guide link the firmware needed for the rollback?
Epzillon@lemmy.ml · 1 pts · 2y
It only states that the necessary firmware can be found on the manufacturers page

The steps to do soo are not hard tho.
You just need the android 13 firmware this one: https://oxygenos.oneplus.net/8173_sign_LE2111_11_F_OTA_2290_all_nRBuNP_00011011.zip
Then enable developers options by tapping "Build Number" 7 times
Enable Usb debugging in the developers options.
Then go to About device > Up to date, 3 dots on the top right and click local install.
Then select downgrade firmware, Extract > Upgrade
If the local install button is greyd out just follow the steps in this guide: https://droidwin.com/local-install-greyed-out-in-oneplus-how-to-fix/

The process itself is not hard no. I just could not find the firmware required.
How and where did you find that link?
