AT&T iPhone 4 on 6.1.3, windows 7. I'm no stranger to jailbreaking, but i've never ran into this problem and i'm a little clueless. I'm trying to run the tethered jailbreak for 6.1.3 but redsn0w keeps getting stuck at waiting on reboot and my screen is lit up, but it's blank, and the jailbreak process never finishes. I've tried rebooting my phone, rebooting my laptop, I've made sure that i'm selecting the correct 6.0 ipsw for my phone (iPhone3,1_6.0_10A403_Restore.ipsw), no anti virus software running on my laptop, and i've tried restoring my phone. Do you guys have any other suggestions?
