MuscleNerd had confirmed some ultrasn0w’s compatibility issues with iOS 4.3.1 after jailbreaking with redsn0w 0.9.6rc9, sn0wbreeze or pwnage tool. iPhone Dev-Team is currently testing the fix and will release it anytime soon.

If you’re eager to fix it now, you can install a patch developed by DjayB6 called Ultrasn0w Fixer for iOS 4.3.1.

  1. This on is driving me nuts!

    iPhone 3GS – Baseband 6.15 – iOS 4.3.2

    Used Redsn0w and 4.3.2 ipsw – Was able to JB and load Cydia… and ultrasn0w…

    Got the 'one bar' (T-Mobile) – no signal "searching" problem – Tried all the fixes – 3G off – Reboot/Reset Network – Remove SIM etc – Found the fix here and tried loading it – but gives me a bunch of red X's – basically won't load (too small and too hard to read error messages – but seems it's not recognizing something on the server) – ??

    This then wipes out my Wi-Fi connection – so I basically end up rebuilding from scratch…

    I've JB this 3GS several times, but never had probs like this before… Wish I'd stayed on 4.1 but the battery burn and not having GPS was wearing on me… so I did the deed

    Any suggestions on how to fix the no signal/searching problem?



  2. Loaded ultrasn0w 1.2.4 and I am having the same issue. Where can I find a source for signal fix? I see only tethering when I search
