no much help here. Do you have exlink cable?
Was here rs-232 jack: debug enabled in service menu before brick?

If no, then mainboard replacement only.

sorry, don`t understand Chinese :(
You`re asking if you could repair it with soldering another chip from spare mainboard?

B series is no TTL. http://wiki.samygo.tv/index.php5/Enable ... l.29_cable

you need:
rs-232 jack: debug

But! B550 has not full u-boot and i doubt you can go further. Sorry.
