Dev Team has just released redsn0w 0.9.10 beta 6, a new version of the program with which we can tethered jailbreak certain iDevices with iOS 5.1 installed. Unfortunately, iPad 2 and iPhone 4S are not included in the list of devices compatible with this program, but the rest of the iDevices that can install iOS 5.1 can be jailbroken using the new version of redsn0w. The new redsn0w does untethered jailbreak only for iPhone 3GS with old bootrom and the iBooks application is non-functional, but everything else should work without problems.
ultrasn0w is NOT compatible with iOS 5.1, so do not update even if you keep the baseband because you will not be able to decode the terminal.
redsn0w 0.9.10 beta 6 jailbreaks using the bootrom exploit from limerain and is compatible with:
- iPhone 3GS;
- iPhone 4;
- iPad 1;
- iPod Touch 3G;
- iPod Touch 4G.
Step 1
Download redsn0w 0.9.10 beta 6 from here: Windows, Mac OS X.
Download iOS 5.1 available here.
Step 2
Connect the terminal to PC/Mac. In Windows, go to the folder where you downloaded redsn0w, right-click on the executable, select Properties and from the newly opened menu go to Compatibility and tick Run this program in compatibility mode for then select Windows XP, Press Apply and then ok. If you do not follow the correct step, you will not be able to start the tethered terminal. On Mac/Windows redsn0w 0.9.10 beta 6), press the button Extrasthen Select IPSW and select the iOS 5.1 ipsw and press Next. redsn0w will implement the exploit and move on to the next step.
Step 3
After correctly selecting the ipsw, press the Back button to return to the main menu.
Step 4
Now you have to enter the phone in DFU MODE. First close the terminal, then return to the main menu of redsn0w where you select the Extracts option then Pwned DFU and follow the steps below:
- hold down the power button for 3 seconds;
- without letting go of the power button, press the Home button for 10 seconds;
- after the 10 seconds pass, release the Power button and the phone should already be in DFU Mode and redsn0w will start implementing the exploit.
If everything worked and the jailbreak was implemented then redsn0w should show you the Finish button.
Step 5
If everything goes well, you should have a jailbroken iPhone, but unfortunately the "fun" doesn't stop there. Your terminal is jailbroken but the applications do not work on it because you have a tethered jailbreak. You must follow the steps below to boot in tethered mode and be able to use Cydia, Safari and other applications.
Step 6
Re-enter the terminal in DFU Mode following the instructions from Step 4.
Step 7
If you have not closed redsn0w, then press the Back button to return to the Jailbreak & Extras menu, i.e. the first one. If you closed redsn0w then repeat the second part of step 2 to select the ipsw for iOS 5.1.
Step 8
After selecting the ipsw, press the Just Boot button from the Extras menu and redsn0w will start the tethered terminal and you will be able to use the device without the slightest problem.
After the terminal starts, you should have access to all applications without any problem. This step must be repeated absolutely every time the terminal is reset because otherwise it will not start at all. This jailbreak solution is temporary, so if you don't want to bother with a tethered jailbreak, you can wait.
