How to repair it ?<br />thanx
depends on what cause the contact service.
try reading past few threads so that you'll know what to do.
by all means, try reflashing it with the same firmware version.
and, pls post the cause of your problem so that forumers here will know what advice to give you.

If you have a Nokia Flasher Cable, just flash it!!!<br />But do remember to take note of the MCU & PPM Pakage use!!!<br />Or else, you will have no network!!!

Fix it with NCKCalc by Viper...Tested working on this model too.
Just a hint: I use the 1.2 moto sw rather than the latest version. <img src="wink.gif" border="0"> <img src="wink.gif" border="0"> <img src="wink.gif" border="0">

Hello,
I suggest you check the phone using Wintesla. If a phone is in "contact service" mode, Wintesla will automatically run its Self test menu and you will see where the problem lies. If the problem lies in the frimware, Wintesla will show you a "failed" test result at the MCU ROM checksum. If that's the case, Lets be conservative and flash from 00200000 to 00300000. That should do it. But if it is in the PPM area or the EEPROM, better just claim your warranty.

Yep, but where to find cracked DLL's that work with this model?
