Hello everyone. I’d like to install /e/OS to may fairly old phone - OnePlus 9 Pro. Currently I have LineageOS 22.2 (Android 15) installed there. The installation guide says that I should have Android 13/14. Does anyone know if it’s still relevant? It was written for a quite long time, and there were few /e/OS major releases during that time. Maybe there is an easier option already than rolling back to old stock firmware?
Hello @kurnevsky, Welcome to the /e/ users forum.
i think stock Android 13/14 was a requirement to install LineageOS 22.2,
so you should already have the original firmware parts.
/e/OS build inlude the needed updated firmware parts as listed below :
./payload-dumper-go -l e-3.7.3-a16-20260507618652-community-lemonadep.zip
