iPhone 4 4.3.5 tethered jailbreak using 4.3.4 ipsw and redsnow 0.9.8b4 So I attempted to restore my iPhone 4 earlier so that I could upgrade to iOS 5. However, iTunes would not let me upgrade, saying that I was ineligible. I've tried to restore via DFU mode with 4.3.5, 4.3.4, etc. with no avail. Now my iPhone is essentially bricked; I cannot get past the recovery screen. I tried rejailbreaking it, but redsnow hangs at about 75% of the little pineapple screen that pops up on the iPhone screen (pwnagetool?). The closest I can come to getting it functional again is about 75% of the restore process to 4.3.5, at which point itunes hangs up and give me either error 1013 or 3004. I have edited my host file in efforts to circumvent eligibility. I have scoured the internet for solutions to my problem, which seems to be somewhat unique at this time. I would sincerely appreciate any help you might offer. Edit: One minute after posting, I have successfully restored to 4.3.5! I can't quite remember what I did differently this time, as I have tried several permutations of different solutions. I think I pointed itunes to a modified 4.3.5 ipsw from DFU mode.
