Read U366 (64Mb) and use RCUnlocker

Thanks, I've read the 8MB chip used the RCUnlocker but gives the following message "Missing unshockable Content"

Attached both chips content

read it again and compare results. It has errors. "unshockable" or unlockable?

in the end the 16MB chip had the password. Tried again to read, patch and write back and it worked.
It seems there were some issues with the t48 programmer and this motherboard but managed to do this with ch341 in the end.
