Downgrade from 13.0.8.0 to 13.0.5.0?

[masterross]

Guys,

How to downgrade to 13.0.5.0 w/o full wipe?
It gives me "can't install this package over newer build" in TWRP

Just deleted the line:
(!less_than_int(1657095343, getprop("ro.build.date.utc"))) || abort("E3003: Can't install this package (Wed Jul 6 16:15:43 CST 2022) over newer build (" + getprop("ro.build.date") + ").");

in the updater script and was able to flash but than I've got:
"wait until device is fully rebooted before opening apps"

Is there a solution w/o wiping /data ?
