hi everyone
i can't modify anything on my damn 3330 v 5.06
after i modify (change original tone , change original grophic , change menu's name ,...etc )
i recalculate Checksum using
PPM Manager and Confirm by PPM Split
then i flash the ppm or mcu + ppm back
then there is no network
i tried (koci FaidLogger ,EEPROM Tool , Nokia Tool 1.8, Knock Phonix "set faid and quick Set Faid,)
i tried them all but there is no network
what i can do to solve it out ?
damn i made modification on my friend mobiles (3310) but couldn't do anything on mine all i can do wiz it
is using logomanager not more
what i can do friend to solve this problem ?

It isn't possible to edit the SW versions 4.30,4.50 and 5.06!!

you must use at least 4.16,so the Faid can be calculated as well.
