i'm new to samsung flashing. recently i received a samsung R8003 for unlock. then tried to unlock it using Z3x box, but it always stops at 3/5 part of unlocking. now it's stuck at S8003 logo. i tried flashing it using Multi-Loader 5.56 (without checking boot change and master rom) but it always says "Error : Rsrc1 Write [0.2s]" then on the phone display says "NAK_INVALID_ADDR". what do you think is my mistake? anyone who can help me out on this? i just need to bring this unit to it's original state. help! help! help!
thanks in advance and more power!!!
