iPhone 4 4.2 tethered jailbreak question

gibbo · Dec 9, 2010

If I'm to jailbreak my iPhone 4, can I safely restore it to factory setting if need be?

Thanks in advance

yes, just plug it in to your computer, and press the restore button and itll be back to normal with no jailbreak

Thanx for you help. Also I'm having trouble finding the restore 4.2.1 ipsw file which I've download to use with resnow. I've downloaded the zip folder which the ipsw file is meant to be in, and when I extract the folder, I can't find it!!??

iPod, iPhone and iPad Firmware Download

just go there and scroll down to where it says iphone, and download 4.2.1 and itll download the ipsw for you, if the same thing happens again did you try using search on your pc, or mac?

but now another problem

while running the jailbreak in dfu mode, it gets to the uploading ramdisk, then half way through, I get a error message saying redsn0w.exe has stopped working!!??

I've tried afew things but no joy!!

Any more advice, thank you for the help
