Over the Christmas weekend, the infamous iPhone Dev Team released a new version of redsn0w that implements the “backup plan” to the 4.2.1 untethered jailbreak. The Team is seeking help from the iOS community to test this redsn0w and find any bugs before the general release.
According to the Team, “backup plan” requires that you have the iOS 4.2 beta 3 IPSW on your Mac, and that Cydia has the user’s 4.2b3 SHSH hashes (blobs).
The hackers also said that they were working on a way to get this technique to apply to iOS 4.1 IPSWs.
Calling this beta backup method the “Jailbreak Monte,” it does not support all current iOS-based hardware.
To be clear, redsn0w 0.9.7b2 only works to jailbreak iPhone 4, iPad, and iPod touch 4th generation, and only if the user has saved his / her iOS 4.2b3 SHSH blobs with Cydia.
“We’re about to release the first beta using this new “backup method,” which redsn0w calls ‘Jailbreak Monte,’” the Team wrote on its blog.
The post continues with what the hackers call “some important points:”
· This is a beta tester program. It’s not a general release! Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
· For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
· Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.
This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
· Cydia must have your 4.2b3 SHSH blobs saved on file. (As we approach a general release, we’ll provide a way to let you use locally saved hashes too).
· You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too). The correct invocation of the relay is just as that page says: “./tcprelay.py -t 22:2222”. If the relay isn’t installed or running correctly by the time the redsn0w ramdisk has started, you’ll need to restore to stock FW again to try it again. Please test it beforehand to save yourself some time!
· Please leave all feedback in the comments below (we really need your feedback to help develop it into a stable release!)
Initially, there was a redsn0w 0.9.7 beta 1 release which had a few issues, but the Team quickly posted a second beta that only suffers from one bug - “Bluetooth disabled due to sandbox problem.”
Finally, the Team urges testers to test the redsn0w 0.9.7b2 jailbreak only a fresh restore.
The reason: “…otherwise it’s impossible to keep track of the variables involved,” according to the iPhone hackers.
