just write 8250 full flash to your 8210 (rom6) and you'll get 8250 function on your 8210. it's easy to make it.

Just try flashing it again but when it says to turn on your phone plug the charger in!!
Your phones battery might not have enough juice!

Also make sure you flash the eeprom to 003D0000 as this is the eeprom address!
