When Apple released iOS 6.1.3 update, everyone (almost) knew that this might fix the exploit that Evasi0n untethered jailbreak was using. Well, that turned out to be so true. If you “accidentally” updated to iOS 6.1.3 on your iOS device, you have lost the jailbreak status.
If you use iPhone 4, 3GS (pre-A5 chip), you are lucky even if you upgraded to iOS 6.1.3. If you’re on any other iPhone or iPad or iPod Touch (A5/A6 device), and accidentally updated your firmware, you have to wait till @pod2g and his team crack the new firmware.
For those of you who updated to the “Evasi0n-killer firmware”, (on iPhone 4, 3GS and older), here’s how to jailbreak iOS 6.1.3 (tethered only). It’s not an untethered jailbreak so you will have to connect the iPhone to your system and boot through Redsn0w every time it switches off.
How to Jailbreak iOS 6.1.3 using Redsn0w
Download and open Redsn0w. In Windows 7, you’ll have to open Redsn0w in XP compatibility mode (Right click on the .exe file -> Properties -> Compatibility Tab -> Run this program in compatibility mode for Win XP). Also, you have to run the program as an administrator.
Connect your iPhone to the computer and close iTunes if it opens up.
In Redsn0w, click on Extras -> Select IPSW. Choose the firmware you just downloaded. (Yes, you should select the iOS 6.0.0 firmware)
Go back in Redsn0w and click on Jailbreak.
Redsn0w will prepare the device for a tethered jailbreak. Just make sure that the Cydia option is checked and optionally, if you’re on iPhone 3GS, check the Enable Battery Percentage.
You will be asked to put the iPhone in DFU mode. Follow the steps shown on the Redsn0w screen. Once in DFU, the jailbreaking process will start.
Once the jailbreak process is done, you will be prompted with the information. Close down Redsn0w and let the iPhone complete its restart. This might take a lot of time.
You will now have to do a tether boot.
Open Redsn0w and go to Extras -> Select IPSW. Select the iOS 6.0.0 firmware you downloaded at the start of the tutorial.
Head back to Extras and press Just Boot.
Switch off your iPhone. Connect it to the computer (if it’s not connected). You might be prompted to go into DFU again. This will help Redsn0w to recognize your device and start it up, jailbroken.
Yeah, it sucks to do a tethered jailbreak after you’ve experienced the bliss of Absinthe and Evasi0n but that’s the price you have to pay for upgrading to iOS 6.1.3.
