[rustyz]

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,

in flashing 8250, you have to flash virgin eeprom using rolis 4.78. this is afrter flashing the mcu+ppm.

after the above process, open nooktool 1.8, enter your phone's IMEI then correct it, clear SP LOCKS, and finally, Calc FAID.

turn the phone off for 3 seconds, turn it again and by this time you should get the signal.

post agai if problem persists.
