When this shows up:

” Unable to find gBdevList Unable to find fs_mount Unable to find fs_unmount Unable to find fs_load_file Greenpois0n initialized ”

You got to wait that itll continue and in few minutes youll be good to go.

If last line doesn`t shows up (Greenpois0n initialized), you got to try it over again from the first step.

See ya

Hi there! I have iPad 4.2.1 and greenpois0n RC6. Tried to do jailbreak on windwos 7 and XP. The greenpois0n was started 'as administrator' on windows 7. The jailbreak failed with the same message - Jailbreak Failed :(

I've changed usb-ports and PCs, but result is the same. Is it possible to help me here?

All done on Vista because it was Vista or because that PC has direct internet connection.

I had a similar problem with 2 different devices on 3 different computers... until I found I needed to have iTunes installed on the computer I was using Greenpois0n... Maybe it's the same thing for you...

Either use Redsn0w or just update using Sn0wbreeze or PwnageTool.
