Bro flashing the phone will not help You to escape from pattern unlock sometimes;
all Yo have to do is to download adb samsung drivers from here and past it in windows/system32;
connect powered phone to pc,install drivers,open cmd and execute comand:
adb reboot recovery.
Your phone will restart and power in recovery mode were You'll have to select an factory reset and that's all.
First time I test it on i5500 but succesfully worked and on other samsung android models like i900
pass for the archive is muieudmr.
