Can you attach your "boot.img" here? Also publishing the building process result will also be helpful to check further, it can be done by "./gradlew unpack --scan" Thanks

boot+vbmeta.zip Here it is. Actually it is my fault, i changed all occurrences of "flags" : 0" on auto and there were two of em. Once i changed just one in line 19 - all good. Havent patched vbmeta together with boot, said "no need".

Good to know it works.

Since "boot.img" appeared as "chain partition descriptor" in the "vbmeta.img", modifying "boot.img" won't affect anything in "vbmeta.img", as long as boot.img is signed with the same key as before.
