I tried that, didn’t work. It is flashable from the OEM recovery and the script will execute just fine, but the other slot won’t be bootable.
Probably something to do with hashes still wrong for Verified Boot, but I really don’t know anything about how that works exactly.
As this is turning waaay OT here, could someone with privileges move the last 10 posts or so over to the FP4 Root Access is possible, maybe a bit risky topic maybe
