How to fix some mysterious problems.

i'm trying to JB my new itouch 4g; it came with firmware 4.1, which i upgraded to 4.2.1, then ran greenpoison 6.1. I can get the device to DFU mode apparently, as greenpoison tells me that it can jailbreak after i do the holding down of the buttons and so forth. However, when I click the jailbreak button it simply does nothing for a few seconds, then fills up the progress bar, then says that the jailbreak has failed. Nothing appears on the ipod's screen while this is happening.

I've tried it more than 10 times, starting with ipod on/off, trying redsn0w, but nothing works. does anyone have any ideas?

  • Reinstalling latest iTunes
  • Restarting computer
  • Using different USB port
  • Using different USB cable
  • Using different computer
  • Using Sn0wbreeze or PwnageTool

Oh, and try the info at to make sure your computer is recognising DFU mode properly, though from your description you do seem to be getting there anyway.

I tried most of the items on that list (can't get to another computer right now), but i didn't know about sn0wbreeze+iREB and the combo worked for me. thanks :)

If you really want a greenpois0n jailbreak next time after you press jailbreak hold down the home button see if that works.
