Setup: Iphone 4 iOS 6.1.3 Redsnow 0.1.9.15b3 Windows 7 Was following this videotutorial https://www.youtube.com/watch?v=HXlzLP1hbKE&list=PLT0Hj8-B-w6MC8iF4jwIlVHOoYngZNPRk&index=1 & this tutorial http://www.evasionjailbreak.com/jailbreak-6.1.3-semi-untethered-ios-on-iphone-4-3gs-ipod-touch-4g/ to do a tethered jail break. Got upto as far as installing Cydia but need to boot the phone tethered. After selecting IPSW,selecting "Just Boot" and then putting my device into DFU mode, the iphone displays the pineapple logo for about 2 mins and then the apple logo appears forever. It just wont boot tethered. The way I recover is to hold down the power button to switch it off and then press and hold the + volume whilst powering on again. Any thoughts ? - Was very nervous since I thought I had bricked my iphone. It was only after googling that I found the suggestion to power on with the + volume pressed.
