How to: Jailbreak iOS 5 beta 7 with redsn0w 0.9.8 beta 7 on the iPhone, iPad and iPod Touch (Windows, Mac)
By During this evening Apple released iOS 5 beta 7 for application developers for iOS, the operating system version brings quite a few changes.
Dev Team yesterday launched redsn0w 0.9.8 beta 7, bringing compatibility with a new firmware version iOS 5 beta 6 for iPad that Apple change it without notice. The good thing is that the new redsn0w version is compatible with iOS 5 beta 7 released this evening so the Dev Team will not update the program but the downside is that you need iOS 5 beta 6 for the jailbreak.
The jailbreak remains tethered to all devices and of course is not compatible with iPad 2.
redsn0w 0.9.8 beta 7 makes jailbreak using the bootrom exploit of limerain and is compatible with:
iPhone 3GS;
iPhone 4;
iPad 1;
iPod Touch 3G;
iPod Touch 4G.
For starters, you must have iOS 5 beta 7 installed in the terminal but you must have a copy of the iOS 5 beta 6 saved in your computer. And pay attention, if you don’t have it than there isn’t a problem, you can buy an Apple developer account which costs $99 annually or if you have any friends or people that can help you, just ask a developer of applications for iOS (or a friend) to enroll the UDID of your terminal in his account and give you iOS 5 beta 6, iOS 5 beta 7 and iTunes 10.5 beta 7.
Step 1
Download redsn0w 0.9.8 beta 7 here: Windows and Mac OS X.
Step 2
Connect your device to the PC. Open redsn0w 0.9.8 beta 7, click Browse, select the ipsw iOS 5 beta 6 and click Next. redsn0w will implement and will exploit the next step.
Step 3
Check Install Cydia and click Next.
Step 4
Now your main objective is to enter the phone in DFU MODE. Dev Team says that closing the terminal is required before introducing the device in DFU mode so I recommend you to close the terminal, then restart and close it again. After the second closed click Next and redsn0w will show how to enter in DFU Mode.
- You can click on the power button and hold it for 3 seconds;
- And then without releasing the power button press the Home button 10 seconds;
- After those 10 seconds has passed just release the power button and you are set, your device is in DFU Mode and redsn0w will begin to implement the exploit.
If everything worked and jailbreak has been implemented then redsn0w should show the Finish button.
Step 5
Now, if everything is exactly like we’ve said here you should have a jailbroken iPhone (quite amazing, yes?), but you have a few thing to do first. Your device is jailbroken but there is a problem, you can use your applications because you have a tethered jailbreak. Pay attention at these steps below to boot in the tethered mode and use Cydia or Safari.
Step 6
Put your terminal in DFU mode by following the instructions in Step 4.
Step 7
Now open redsn0w, and your next step is selecting the ipsw for iOS 5.0 beta 6, click Next and then “Just boot tethered now”. Wait and see.
And finally after your device starts you should have access to all of your amazing applications without any kind of problem. This step must be repeated each time your device has been reseted because otherwise it will not start at all.
