For those of you who have used the Evasi0n iOS 6-6.1.2 untethered jailbreak on your iPhone, iPad or iPod, you know sometimes installing certain combinations of tweaks or even one particular tweak may cause your system to go a little out of whack, and in some cases even get you stuck in a respiring loop. Until recently, the assumption was that your only choice then was to restore the device via iTunes, which automatically updates you to 6.1.3 or 6.1.4—and if you own an iPhone 5, 4S, iPad 2 or above, out goes the untethered jailbreak. Thankfully though, that may not be your only option.

It seems for those running any jailbreak, including an iOS 6.1.2 untethered jailbreak, on iPhone iPad or iPod, you can restore or semi-restore your device to its "factory" 6.1.2 settings by using a nice little tool called iLex R.A.T.

If the Cydia jailbreak tweaks on your system seem to be causing it to run slow, crash and do other crazy things, then the iLex R.A.T. is definitely a tool you should try. The R.A.T. stands for "remove all tweaks," so it allows those running a 6.1.2 untethered jailbreak or lower on their iPhones, iPads and iPods to restore the jailbroken device to a tweak free or "clean state" but still retain Cydia and your tethered or untethered jailbreak. This is great news, particularly for those using iPhone 5, 4S or iPad 2 and above where a downgrade option is not a possibility.

Below are instructions and a video (modified from iDownloadBlog) on how to install the tool and restore you iOS 6.1.2 untethered jailbreak or lower with iLex R.A.T.

Install iLEX Rat On Your iPhone:

STEP 1: Open Cydia and add the following repo:

STEP 2: After the repo is installed on your iPhone, You should see an iLEXiNFO source under your list of sources. Tap on that source, and install the iLEX R.A.T. package.

NOTE: After installing iLEX Rat you will notice there is no app icon or settings for the tweak

STEP 3: Install MobileTerminal which is available in the BigBoss repo. Once you install MobileTerminal, your device is ready to be restored.

Keep in mind that while iLEX RAT can focus on just the Cydia aspects of your device, it is still capable of returning your entire device back to a stock nature. So it's imperative that you back up your device before performing any restores. Actually, iLEX RAT itself has a back up and restore tool, but that goes beyond the scope of this introductory tutorial.

How To Run iLEX Rat on Your iPhone:

STEP 1: Right now Open MobileTerminal and type "Rat" (Without the quotes), and then on the command line, tap "enter." The iLEX RAT interface will load, and you'll see a plethora of options. The option that we're going to focus on for this tutorial is the full restore (option 12), because that's most comparable to SemiRestore.

STEP 2: Select option 12, select yes, and the restore will begin.

STEP 3: After your device is rebooted, you'll see the iOS setup wizard to reconfigure your device. The only thing that will be left on your device after a restore is Cydia, along with the source for iLEX RAT, so that you may easily install it again.
