just wanna share with you my experiencing about flashing my 8250(version 5.06) to 8850(version 5.29). Proven ok. But i think the program/flash of 8250 is much better than the 8850. So i decided to flash back my 8250. Try it for yourself. You'll see!!

Reminder:

No need to change any chips or ic...if you have 8250 version 5.06 or above just flash it to 8850 much better the latest version.

or if you want to UPGRADE it to 8855 all you have to do is change the FLASH IC only.

IF YOU NEED THE FLASH OF 8850 JUST LET ME KNOW.

????????:(

The 8850 is the same phone as the 8210!? It just has white lights and a metal sliding cover! Why would you want to downgrade your phone from an 8250?

1st you need an 8210 with a ROM6 CPU!
2nd you need a full 8250 flash! (MCU+PPM+EEPROM)
3rd all cables and software (flashing)

Just flash your rom 6 8210 with a full 8250 flash!
DONE!

Use a data cable and use Rollis Nokia Tool, this will tell you the ROM version if you click read!
