6210 Contact service - unable to read eeprom area - GSM-Forum

Hi, All

When I tried to read full flash by Rolis and checksum was wrong. Phone was 4-lock closed, had IMEI like 6565656... etc. It's impossible to read-write eeprom area, but MCU&PPM are readable-writable. Probably flash IC dead? If I will change IC how to restore eeprom data?

you must write fullflash from 00200000 to 00600000 (it is mcu + ppm +eeprom)
backup will by the best
