Step 7: Wait for Redsn0w to do the rest for you. Hold “Power” button for 3 seconds, without releasing power button, hold the “Home” button for 10 seconds and release power button but keep holding Home button for another 30 seconds. You will now need to put the device in DFU mode. Step 6: Turn off your device and connect your device to the computer. Step 5: Now select “ Install Cydia” and click “ Next”.

How to Jailbreak iOS 4.2.1 using Redsn0w 0.9.6b4 Also, if you rely on the ultrasn0w unlock, this jailbreak is not for you and hence you need to wait for now. In case you prefer untethered jailbreak, wait for an updated version of JailbreakMe. Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (Non-MC Model) can be jailbroken-untethered right now using this latest version of Redsn0w. The tethered jailbreak condition in Redsn0w 0.9.6b4 however only applies to the new devices like: iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC Model), iPod touch 3G and the iPod touch 4G. The iPhone dev team has already released RedSn0w 0.9.6b4, based on Geohot’s Limera1n bootrom exploit, which brings first proper jailbreak, with working Cydia for all iOS 4.2.1 devices.Ī major negative about going for Redsn0w 0.9.6b4 is that it is tethered jailbreak which means you will need to rejailbreak it everytime the device is rebooted (just like Blackra1n).
