It should be safe to assume that when it comes to tools used to jailbreak an iPhone, iPad and iPod touch, one can say that Redsn0w is certainly one of the most reliable go-to solutions. And now good news for avid users of Redsn0w because Dev-Team just added a major feature to their jailbreak tool. More details about Redsn0w 0.9.11b2 after the jump.
The iPhone Dev-Team announced on their blog the major changes to Redsn0w with a header that reads "What’s old is new again!" With Redsn0w 0.9.11b1, owners of newer devices which includes the iPad 2, iPad 3, and iPhone 4S, will now be able to downgrade to the IPSW of their choice, a feature which used to be exclusive for older devices that pre-dates the iPad 2. In order to access the new downgrading feature, go to Extras->Even More->Restore.
Here are some important things to keep in mind before using the new feature from Dev-Team Blog:
- You cannot downgrade without the personalized SHSH blobs for your device at that lower firmware. You need to have fetched those blobs while the signing window was open, using either Cydia’s built-in TSS@Home feature, or with TinyUmbrella. The new Restore screen of redsn0w lets you choose either the remote blobs or local ones (for the earlier firmware). If you don’t know where TinyUmbrella put your blobs, TinyUmbrella has a button that will show you (copy them out of that folder and feed them to redsn0w).
- The A5 downgrade method actually updates to the latest firmware before downgrading to the earlier one. This process updates your baseband to whatever is newest. DO NOT USE THIS METHOD IF YOU RELY ON UNOFFICIAL UNLOCKS of your iPhone4S. Those who used the temporary SAM technique to unlock their iPhones to specific SIMs shouldn’t be affected by this baseband update.
- This update involves a bunch of new redsn0w code. We recommend sticking to the previous version 0.9.10b8b unless you’re specifically using this new feature, until all the bugs are worked out! (Note: If redsn0w gets stuck at the “Waiting for device” stage for more than 30 seconds, you’ve hit a pesky GUI bug…that will be fixed in an upcoming version!)
The version 0.9.11b1 has been long update to version 0.9.11b2 which adds support for the “9A406” version of iOS 5.0.1. As the Dev-Team relates, this particular downgrade method can be fixed by Apple, so if you could really use this new feature, we recommend that you use this feature right away. And unless you want to use the new downgrading feature, you are better off with using Redsn0w 0.9.10b8b which is a much more stable version.
