Green Poison DONT WORK for me WTF How do i jailbreak this 3gs??

[coolguy123123]

I just had to restore my 06.15 unlocked with redsnow and ultrasnow. But now it was giving me problems today so i had to restore it. So now i got it restored by getting a 4.2.1 firmware and pwntagetool and restored it wit itunes. So now it works but i cant jail break it. The green poison jailbreak stops at "Unable to mount filesystems" So i have no idea what to do? How do i jail break this thing?

Please try and stick to the same thread for help. Creating multiple ones for every different issue you come across is only going to make it harder for people to help you.

You say you used pwnage tool to make a custom 4.2.1 and restored to that right? If that is the case you dont need greenpoison after. You are already jailbroken and should have cydia.
