re-soldered jtag onto known sammy I know the IRD and bk for this one but when I try the byte to check I get rubbish, only IRD is correct, has anyone else has this problem???
Put box in debug mode m8.. hold down up + down until you see ld14.. wait till you see snd.. run mac mot.. open config 1 in bke 2.2 and check bytes (used 0x008D6284).. click connect.. you should have a valid ird and bk..
