use nokia tool v1.8 by rolis, correct imei, sort sp locks and then update faid !

if this fails then u have corrupt flash file !

If the SW is OK, then it is HW. Try to run the test with Eeprom tools or Wintesla and see what it says. I think the CCONT or COBBA have to be reballed. Good luck.

What do you do when you reball CCONT or COBBA?

[Romano1]

Well, it is just take out the BGA chip of PCB and make new soldering balls on the chip. But you need special raballing kit and hot air station. If you do not know what I am talking about, just do not mess with it and take it to the service. But run the tests first, it could be the SW not the HW.
