How to Downgrade LineageOS ROM
In this video, we will show you the steps to downgrade the LineageOS ROM from a higher OS version to the lower version.
While I have done the downgrade from LineageOS 21 to LineageOS 20 [Android 14 to 13], but the steps are applicable across all the versions of Android/Lineage.
For the sake of reference, I’m using a OnePlus 9 Pro and the files are flashed corresponding to that device. The partition files and hence their associated commands might be different for your device. If you aren’t sure of those commands, then either search the flashing guide on my site droidwin.com or ask me in the comments.
Last but not the least, the downgrade process will wipe off all the data from your device, so take a complete device backup beforehand.
