Jailbreak iPhone/iPad/iPod touch with iOS 4.2.1 using redsn0w 0.9.7b5 [Bluetooth Fixed!]

The iPhone Dev Team is working hard on their backup plan to iOS 4.2.1 untethered jailbreak. They’ve released the fifth beta release of redsn0w 0.9.7 which further advances their efforts. While this will help you if you have iOS 4.2b3 firmware and iOS 4.2b3 SHSH hashes in Cydia, it’s advised you don’t try this unless you’re a registered iPhone Dev with legal access to iOS 4.2b3 firmware. Don’t pirate it, please! redsn0w 0.8.7b5

Here’s the official word on this release by the iPhone Dev Team:

The fifth beta is now available (testers ONLY please!).  Bluetooth is now working (and any sandbox-related issues should be resolved too).  Please do not pirate the 4.2b3 IPSW! Only those enrolled in the iPhone Developer program have legitimate access to that IPSW using these links (the links won’t work unless you’re a legit developer currently logged in).

redsn0w 0.8.7b5 In case you’re a registered developer and are able to log in while trying jailbreak your iPhone, iPad or iPod touch, here’s how you can do it:

Note: this is a Mac only release yet. Also, do a fresh restore if your iOS Device was jailbroken with the previous betas.

  1. Download redsn0w 0.9.7b5 redsn0w 0.8.7b5
  2. Browse for iOS 4.2.1 firmware
  3. Select Install Cydia and Jailbreak Monte. After checking Jailbreak Monte, it’ll ask you for iOS 4.2b3 firmware, point redsn0w to it.
  4. Put your device into DFU mode. Here’s how : Turn off your device and connect it to the computer. We’ll have to put it in DFU mode now. To do this, hold the power button for 3 seconds, and then hold the home button too without releasing the power button for 10 seconds. Then release the power button but keep holding the home button until redsn0w starts doing its thing.
  5. Once redsn0w is done and your device reboots, it’ll be jailbroken. Enjoy! This time with proper Bluetooth working!

  1. I heard they were releasing a jailbreak Christmas weekend not a limited beta for macs… No I’m not ungrateful I have donated and still waiting but all these betas are just teasers.. Might as well wait for 4.3 I’ve already waited this long. This is turning to be ridiculous and apple is probably waiting form them to release this then patch it up and release 4.3 weeks later

    1. You’ll have to be patient. They’re pushing out betas regularly and progress is apparent in them! We’ll keep you updated as soon as they release a Windows version
