Problems with 5110 v5.11
 

These are the facts,

reading flash with Nokia Flashtool my mobile went into CONTACT SERVICE after an accidentally disconnection.

NFREE told me that the MCU Checksum was wrong.<br />The EEPROM went wrong too. Invalid checksum and IMEI

The steps I've done to repair this are:

I put a new 1Mb flash (www.chavalgsm.com) in 5110 with Rolis 5.14 SW and repaired the MCU SW Checksum with Rolis too.

With this, the phone powers on but no coverage.

I download the eeprom and repair checksum and IMEI with Bartek SW, but when I tried to upload the new eeprom with Rolis SW or NokiaSP it failed!!!

Now i have my phone with no network coverage!<br />Any ideas to reasemble this? Perhaps Pony Programmer?

Best regards and thanks in advance

Hi!

In 5110 eeprom is external...<br />That means is not emmulated in flash like other nokia models...

C ya!
