@Generik

- Firstly Just connect your phone Wintesla using Mbus cable(phone must be ON) and check if it is hardware problem or software....

- If it shows Cobba or CCont Failed... just rehot it and if not work then change it.

- And if it shows Mcu, Ppm, Eeprom tune or Eeprom Sec checksum failed then just full flash you phone with another good flash, using flasher cable and Knok tool...

- After flashing you will see "Insert sim card" on your phone screen, then just make (1.) Clear SP (2.) Change Imei (original imei) (3.) Update Faid ... in Nokia Tools1.8 using Mbus cable

That's all

Regards,
Tanvir !!!
