Redsn0w update lets iPad 2, new iPad, iPhone 4S downgrade to older firmware
The iPhone Dev Team released version 0.9.11b1 of redsn0w last week that lets you restore IPSWs directly to your iPad 2, iPad 3 and iPhone 4S. This means recent iOS device owners can now downgrade their firmware using the jailbreak tool. This is good news for folks who updated to iOS 5.1.1 or iOS 5.1 and want to go back to iOS 5.0.1. You do need your SHSH blobs from the earlier firmware if you want to downgrade, but Cydia usually saves those files automatically for you. For detailed instructions, point your browser to the iPhone Dev Team's blog. [Via JailbreakUntethered]
Use iFaith v1.4 to downgrade to iOS 5.0
The jailbreakers among you are probably anxiously awaiting the first untethered iOS 5 jailbreak promised by pod2g and MuscleNerd. However, if you've upgraded to iOS 5.0.1, you'll be out of luck because the first untethered jailbreak will be for iOS 5.0 only. Nothing later. In iOS 4 and earlier, you could simply restore your iPhone to the base version of the firmware (ie: 4.0), but with the introduction of iOS 5, Apple made it so that once you upgraded the OS to a later version (ie: 5.0.1) it was impossible to downgrade via a restore to the base firmware. However, as Morpheus from the Matrix said, some rules can be bent and others broken. Hacker iH8sn0w has released a (currently) Windows-only tool called iFaith that allows users to downgrade to iOS 5.0. This will enable users to then apply the future untethered jailbreak patch to their iOS 5 device. For those of you who are interested in how iH8sn0w accomplished this feat (using SHSH blob vulnerabilities) you can check out this short YouTube video. [via Engadget]
iFaith v1.4 allows downgrade to iOS 5.0, jailbreaker's dream come true
In the game of Apple versus the jailbreakers, Cupertino threw the community a curveball with iOS 5's newly restricted downgrade system which blocks devices from restoring to old 5.x firmware. With the help of his noble steed iFaith (a custom Windows tool), hacker iH8sn0w has found a way around the firmware block, making it possible for dumped iOS 5 signature hash blobs (SHSH blobs) to permit unsigned restores. Why all the fuss about downgrading to prohibited firmware? Prominent iOS hackers MuscleNerd and pod2g have stated that the first untethered jailbreak will arrive on iOS 5.0 and, as such, may require iFaith's downgrade process to facilitate user restores. While the jailbreak is still under construction, iFaith should assure disheartened users in the community that all is not lost. Want to learn about blobs, blobs, and more blobs?
