Hi all Hope you can help me, I have a Samsung SGH-M620 which has frozen up, it starts up, asks for password, and PIN then all the buttons are dead, a little while later it reboots, and this keeps repeating. Is there a way to master reset this phone?
you can reset the phone by powering it on without simcard then enter *2767*3855# if this fails you need to go to an unlock or service shop for a firmware update
