8210->8250=black screen

[hexspoor2]

I flashed my 8210 with software from a 8250. When i press power on i get a black screen with back light. Then the phone stalls. Does this mean i have a ROM 5? When i read the phone info with Nokia Tools it says that it is ROM 0.

This happens when you have a rom 5 phone. It happened to me too.

8210 with dsp rom5 cannot be converted to 8250.....it shoild be 8210 with dsp rom6 to be able to convert...
if you have flash your phone with rom5 then it has black screen..just flash your backup.your phone will be ok.
