 SMP firmware is not supported. 

 It could be fixed remotely in free time only. 

 Send the dump to email

 Alternatively relearning cycle could be done. Some chips allow FCC update in one go.

FCC location for this SMP firmware is unknown. The only method is of trial and errors with random parameters change. 

but how did you manage to update from 224 to 807?
