[varun29]

I was trying to jailbreak my iphone 4 with redsn0w 9 10b3 but while patching the redsn0w stopped working . I have tried every thing but it did not work . I have windows 7 with norton as anti virus i have disabled that also but it didnot work

same thing happened to me.

I was trying to jailbreak and unlock an iphone 3g. Program just quits without warning and no error message. It happened as i tried to enter DFU mode.

I followed this guide: iclarified.co m/entry/index.php?enid=12949

Tried it with the same results on my windows 7 pc, and macbook air.
