The latest i have tried is Pwnagetool 4.2 create a custom restore and the error I get is error 21
Let me go over this again. I use pwnage 4.2 create a custom restore then it asks me to put it in DFU ( I do) .Then Itunes opens I select the custom restore itunes starts out then errors The Iphone never comes alive no progress bar nothing . then I have to hard reboot to get it going again. weird.
I have seen some posts about having to upgrade from 3.1.0 to 3.1.2 first ? Just nervous about that DONT WANT TO UPGRADE BASEBAND im at 5.11.07 and want to keep it there Thanks for any help
