Hello. I have a iphone 4 that has been jailbroke once before. It had ios 5.0.1. My problem is that it froze up on the apple logo and I had to use itunes to restore it and had it updated to ios 6.1.3 firmware. I haved tried to downgrade to ios 6.0.1 for an untethered jailbreak useing the newest version of redsnow. I made a new folder on my desktop and I put redsnow in it and I also ,unzipped ios 6.0.1 firmware to the folder but when I use redsnow to select the IPSW, it won't select it. Can anyone please guide me through this process one more time. I jailbroke it the first time with lottle problem but this time has been a real headache. If someone could give me step by step instructions it would be greatly appreciated. Thanks in advance.
