Jailbreak iPhone OS 3.1.2 with GeoHot’s Blackra1n

by: - Last updated on: December 17th, 2016

Apple announced the latest upgrade to iPhone OS 3.1 – firmware version 3.1.2 early last week and if you are waiting to jailbreak iPhone OS 3.1.2, the sad news is that the iPhone Dev team is yet to release the Pwnage and redsn0w tools. But the good news is that, if you are waiting to jailbreak your iPhone, GeoHot has just released BlackRa1n, which will allow Windows users to jailbreak their iPhone with OS 3.1.2.


Jailbreak iPhone 3.1.2 OS with Blackrain

Warning: The current update of Blackra1n only supports iPhone OS 3.1.2, do NOT use this tool if you are using an earlier version of iPhone OS. We have unconfirmed reports that BlackRa1n supports iPhone OS 3.1 as well, but we are not sure.

Also, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded.

    Apple has released a new version of iTunes, iTunes 9.1 which changes how certain things work. If you have upgraded to iTunes 9.1, several programs will start giving you an error that ASL.dll is missing.

    The solution for this is simple, you will need to place the Blackra1n executables in the Apple folder under Common Files in Program Files. The folder would be located in the following locations:

    32 Bit – C:\Program Files\Common Files\Apple\Apple Application Support

    64 Bit – C:\Program Files (x86)\Common Files\Apple\Apple Application Support

    Once you copy the blackra1n executable to the above folder, create a shortcut for it on the desktop and double-click it to run it as usual.

    Update: If you continue having problems with Blackra1n, you can use the new Spirit tool to jailbreak iPhone OS 3.1.3 and others.
