i couldn't break the security lock on 5310 so i updated fw to the latest version with phoenix...

the problem is that my friend wants croatian language pack on it but i can't find any fw that has it...

mobile is locked to croatian network (VIP) and it still doesn't support the newest fw over NSU...and i know there is not possible to downgrade fw,not with usb...is there a solution?? what will happen if i change product code for balkans that is his original and go to NSU?? i don't have VIP network SIM so i can't try at the moment
