Hi guy,
I currently own two nokia 8250 which both faces a problem.(contact service) but the two handphone problems are presented in a very different way.

The will seem to appear fine first nokia 8250upon switch on but after a couple of second.it will auto restart and display contact service and hang,untill i pull the battery out.

The other 8250 when I switch on the phone it will immediatly display contact service and remain hang.

What should I do to the phone,to order to repair the phone.what do you guys advice me do. I would like to know how the problem occurs and how to fixes with what tools,software and hardware. Thank you for reading this message.
Yours sincerly,
rustyz

most of the 8250 showing contact service because of the software problem.

In ur case it is not hardware problem................

1. Its only the checksum fail of the mcu & ppm area. Just reflash or upgrade with working flash file and calculate faid.

2. I thought it should be a EEprom corruption, just flash a virgin eeprom to the phone, correct ur IMEI and calculate faid.

Hopes it should work for u.....
