QuickPWN Jailbreak results in boot-loop 

Just spreading the words. I just tried to jailbreak my IPhone with the latest version of QuickPWN (2.2.1). The Mac-Version did not work at all for me for some weird reason, so I tried the Windows one and it seemed to work fine… until the end. The final reboot never ends, the device reboots every few minutes, vibrates and showing the startup screen all the time. Besides accessing the pictures located on the devices I could not access the Phone anymore.

Seeing this problem on some comments on several pages on the web I almost gave up and restored the device with iTunes and my last backup.

Then I stepped on this page that explains a possible solution that actually works! In some way it makes sense in some other not. The problem is, when the device already contains installed programs by the AppStore when the Jailbreak is started they may block the device on the final reboot. Maybe its a deeper reason but actually it helps to turn off the App-Sync for all Apps within the iTunes Sync-Settings. Once that is done the Jailbreak worked fine. I re-added certain Apps after the Job was done and it still works fine.

Hope this post helps.
