There is two ways to flash with Dejan Nokia Flasher, Full or partially. 1. Partial Flash: is used to unlock and always should be used the same sw version file as you have in your mobile phone. This files have 64 Kb. This process take just 7 seconds. 2. Full flash: is used to unlock, repair broken phones or change phone language. Flash memory is fully changed with this procedure, EEPROM should be programmed too, but sometimes is suficient just only programming flash memory, if mobile phone not have coverage later you have flashed you must program EEPROM too, flash and eeprom files must have same sw version and language. To write or program EEPROM memory is necesary an SMD EEPROM programmer with SOIC clips (available at ucables.com from February, 2001). Flashing process can take between 1 and 3 minutes. Size of flashing files are between 500 and 1400Kb. The difference to make a full flash or make a partial flash is to used different flash files and range of addresses.If you don't need to change language, we recommend you use a partial flashing. If you really need full flashing, the best way to do it is to get another unlocked mobile phone of the same version and read flash in the appropiate address range and read eeprom. Later you must write flash and EEPROM to the phone that you want to make full flashing.
