Okay! i have and iphone 4 previously jailbroken. I upgraded to 4.1 wanting to jailbreak that. And now it wont go into DFU mode. DOnt say it is user error. It is not. I have fallowed everything exactly multiple times. I got into DFU mode erlier and the jailbreak failed and since then no luck at all doing the exact same thing.. Is there anyway to put it into DFU mode on a mac without having to push buttons or anything? Everytime i try and put into DFU mode it jus boots back up. Even when i let go of the power button as soon as it goes black. It will either turn off of or boot back up. It boots back up usually. And i am holding the home button the entire time.. Thank you for your help!
