I don't have proper dumps for this model.
All the files I got from vinafix, seem to be bulshit.

Specify which CD3215 chips stay at 5V.
Compare diode mode readings around all them.

Sometime S-UEM2 tester doesn't make good contacts; possibly flex issue.

Test this, just in case:

A1989 820-00850-A UB090 .bin

drive.google.com

Keep in mind, I can't assure is good!
