How to fix some mysterious problems.

I have a 4.2.1 with a 1.59 BB and trying to JB with the win version on 64bit.

No matter what I do, it will NOT go into DFU mode. I have followed the instructions to the letter. On the third section when I am holding only the home button you can hear the high/low tone indicating USB going out but the low/high tone never happens. About 9 seconds left I get a weird tone I have never heard before.

I am stumped... HELP

sorry none of those things help.

On the third step at 9 or 8 second it makes a quick dum dum dum and finishes the count with a failed message. It is not the typical USB sound

Could be that it thought it was unplugged. Try maybe using a different cord of a different UsB port
