Hi all...Errr i need help with an flash/upgrade on a Nokia 5210? After flashing to Software V5.25 From V5.16 im getting no power up( or bootup ), after checking with Rolis Flasher 4.78 it says that theres an error with "Bad Checksum" and i will probably get contact service!! message but still no bootup. Has anyone got any ideas for a fix as the wife will hang me out to dry :-?

Im working with Windows Xp Pro with userport.....
