I have an iPhone 4 laying around that I have jailbreaked (tethered) last year. It's running iOS6.0.1. That worked. Now, I tried doing it but several things don't work. Tethered boot: unrecognized build Select IPSW. None of the IPSW that I downloaded back then for the jailbreak are working, redsn0w says that the IPSW is not supported. Running redsn0w 0.9.10b5c btw. Jailbreak again: it passes 2nd stage and reboot, gets stuck at identifying build, saying it's unrecognized. Then the iPhone just reboots Reset deleting all settings and content: boot loop So I thought it might be a good idea to just push the firmware to the phone again for a full reset. But of course iTunes will only download and install the latest version....does anyone know how to solve my problem and/or how to install 6.0.1 firmware on my iPhone? I'm kind of an iPhone n00b, being an Android-owner, but I have really tried and also used Google quite a lot. Hope you guys can help me.
