did you update faid after flashing?

if not, use Nokia Tool by Rolis with a mbus cable to do so.

you may have to remove sp locks (unlock), then update faid again.

--edit--

also make sure that the imei is the original imei. sometimes it erases when you flash the eeprom.
if the imei is not the original one, open Knok, go to Phone Settings > Set New IMEI > Use original IMEI.
then go to Phone Settings again, and choose Quick Set FAID.

i do all of this that you are tell me.but the problem is continue.what is wrong?what i can do for this?have you got any idea?

i think the best option is to reflash the backup of your 6210 back to the phone. maybe the 6250 flash file is corrupted.

if you have a working 6210 upgraded to 6250, you can simply upload a full backup from your phone.. (or maybe mcu and ppm is enough?).
