How to Use Redsn0w to Jailbreak iOS 5.0.1
Update: An untethered Redsn0w jailbreak is out for iOS 5.0.1!
If you don’t like the tethered boot process, hold out for an untethered release which is actively being worked on by the Dev Team, no ETA is available for that however.
- A supported iOS device: iPhone 4, iPhone 3GS, iPad 1, iPod touch 3rd or 4th gen – there is currently no support for iPad 2 or iPhone 4S
- iOS 5.0.1 installed already – download it here or use the OTA update if you haven’t already
- The previous iOS 5 IPSW for the device
- Redsn0w 0.9.9b8 – get it for Mac or grab it for Windows
The jailbreaking process will be familiar to anyone who has done this before or who has used a custom IPSW. The main thing to remember here is that you are pointing at the older IPSW file despite running a newer version of iOS, this will continue to be the case until a new version of redsn0w is released to circumvent that aspect of the procedure.
Jailbreaking iOS 5.0.1 with Redsn0w
- Turn the iOS device off and then connect it to the computer
- Launch Redsn0w and click the “Extras” button, then click on “Select IPSW” – locate the iOS 5 IPSW (not iOS 5.0.1) and click “Open”
- Click “Back” to return to the original Redsn0w screen and click on “Jailbreak” as usual
- Put the iOS device in DFU mode as redsn0w instructs, holding down the Power and Home button for 10 seconds, then release the power button but continue to hold the Home button for another 15 seconds or so
- As the jailbreak works, the iPhone/iPad/iPod will reboot and you’ll get a notification that it requires a tethered boot, let the device boot up as usual and then put the hardware into DFU mode yet again so you can perform the tethered boot and get Cydia to work
- Back in Redsn0w, go to “Extras” and select the iOS 5.0 IPSW again, then click on “Just Boot” at the top of the “Extras” menu to perform the tethered boot
- Enjoy your jailbreak
If you have a white Cydia icon it’s because you didn’t perform a tethered boot properly, so just go through that step again and you’ll be fine. From this point it’s recommended to install the semi-tether since it improves the experience, it’s a free download from the Cydia store.
If all of this seems confusing or causes a headache, just wait until a new version of redsn0w is available or better yet wait for the untether.
