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.
If you can't get to download mode or anything, then yes you'll need JTAG.
