iOS 6 GM was released yesterday, and it was shortly followed up by a release of the RedSn0w 0.9.13dev4 jailbreak tool.
Again, as with all RedSn0w releases for the iOS 6 beta, this tethered jailbreak will not install Cydia, but instead provides SSH access for developers.
Take a look inside for our full walkthrough that shows how to jailbreak iOS 6 GM with RedSn0w…
Note: You need the iOS 6 GM firmware to proceed. This jailbreak does not install Cydia.
Step 1: Download RedSn0w 0.9.13dev4, and run it.
Step 2: Place your A4 device (iPhone 4, iPod touch 4th gen) into DFU mode.
Step 3: Click Extras > Select IPSW > and point to the iOS 6 GM firmware for your device. (You must be a developer to access this firmware).
Step 4: Once the firmware is successfully identified, go back to the main page and click Jailbreak.
Step 5: Make sure that Install SSH is checked, and proceed. Your device will now be jailbroken.
Step 6: Once the jailbreak process is completed, put your device back into DFU mode.
Step 7: Go back to the main page of RedSn0w and click Extras > Just boot. This will perform a tethered boot on your device.
Step 8: You should now be able to access your device via SSH. By this means you can install the necessary things you need to enjoy your jailbroken device as a developer.
Once iOS 6 is released to the public next week, we are sure that RedSn0w will be updated to include Cydia for regular users who aren’t developers. Another round of waiting for jailbreak starts, we will keep you updated!
