i tried the NB1 to MK2 method. the odin failed for no reason, saying that "Completion(write) failed". i tried several times and tried again after rebooting the computer and it worked. but the problem is that my phone wont boot. it's stuck on the samsung screen. how do i fix this? i did everything right! i double checked before initiating the odin. the phone wont even go to the downloadmode. Can JTAG fix this? JTAG worked last time when my MF3 got bricked.
