OnePlus 9 LineageOS installation question (lemmy.ml)

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!

Doesn't the Lineage guide link the firmware needed for the rollback?

    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?
