Available Options to Get Untethered Jailbreak on iOS 4.3.5

Hi, I have jailbroken iPhone 4 and it is running on iOS 4.3.5, accidentally upgraded from iOS 4.3.3. The thing is, it’s a tethered jailbreak and it is very frustrating because I have to boot my device using Redsn0w on every restart. Anyway, I am thinking to get untethered jailbreak on iOS 4.3.5. So, what should I need to do? Thanks.

Hello Arnold, unfortunately, there’s no way you can get untethered jailbreak on iOS 4.3.5 due to the fact that the untethered jailbreak (which was discovered and developed by the German iPhone hacker and security expert Stefan Esser) works only on iOS 4.3.3 . Additionally, Comex’s JailbreakMe 3.0 (which is an untethered jailbreak) is limited only to iOS 4.3.3. So to get an untethered jailbreak, the best thing you can do is downgrade your iPhone 4 from iOS 4.3.5 back to iOS 4.3.3. If you have a saved iOS 4.3.3 SHSH Blobs created using TinyUmbrella, then you can check this blog post on how to downgrade using iPhone firmware using TinyUmbrella.

If you don’t have a saved iOS 4.3.3 SHSH blobs, then you don’t have to worry because you can still create a signed iOS 4.3.3 and downgrade your iPhone back to iOS 4.3.3 using iFaith SHSH Blobs Dumper. You can refer on this tutorial on how to create signed iPhone firmware using iFaith.

Then once you have successfully downgraded and restored iOS 4.3.3 on your device, you can now jailbreak it to get untethered iOS 4.3.3 jailbreak. You can use the web-based JailbreakMe 3.0 or Redsn0w 0.9.6rc19 (Mac OS X / Windows). The step by step guide on how to use JailbreakMe 3.0 can be found here, while the tutorial for Redsn0w is posted on this link.
