Jailbreak firmware 3.1.2, For all Apple devices
blackra1n is a program for jailbreaking all devices with firmware 3.1.2.
All actions you perform at your own risk! Read carefully before performing any action!
To complete the procedure, you will need:
- blackra1n for your OS
- The newest version of iTunes
- Firmware 3.1.2 installed on your device (can be downloaded directly from iTunes or here )
- Wi-Fi access point, to install unlock and Cydia
Download the utility from the site blackra1n.com (Click on the Windows icon) and save the file to the root of the C drive (Be sure to root, otherwise errors may occur).
Launch blackra1n.exe and click on the "make it ra1n" button (iPhone is connected to the computer).
The process begins
The device goes into Recovery Mode and if all is successful we will see Geohot’s face. Upon completion, the device reboots, after a reboot, we get to the LockScreen we are used to and unlock the blackra1n program icon.
Run blackra1n in the iPhone, set a checkmark in front of sn0w and click Install (at the top right). Then we choose what we need, namely Cydia or Rock (choose one thing, it is not recommended to install everything together!) And again click on the Install button that appears.
After the completion of the process, we have a jailbroken device with Cydia installed (in our example)
For programs such as iFunBox or iPhoneBrowser (these programs are very useful and allow you to browse your system using USB, not WiFi) after jailbreaking, you need to do the following manipulations (Wi-Fi required):
For correct operation of applications based on MobileSubstrate (Winterboard, SBSettings, etc.), you need to run Cydia and reinstall MobileSubstrate .
