iOS 6.1.3/6.1.4 Untethered Jailbreak Might Be Released next week if everything go as planned. This is the vibes we have been getting of late, especially with the recent tweet made by iH8sn0w on Twitter.


According to info reaching us, the exploits needed to fully jailbreak iOS 6.1.3/6.1.4 untethered is available but not totally stable yet for public released but should be in matter of days.

Of course, iOS 7 released yesterday to the world and many would have upgraded to it. Although, the evad3rs team are certain that iOS 7 untethered jailbreak will happen soon enough in coming weeks, yet not so many people want to load the iOS 7 on their devices.

So if you are one of those people that wan to remain with iOS 6.1.3/6.1.4, an untethered jailbreak is closer to you than you might imagine.

Besides, Apple is still signing iOS 6.1.3/6.1.4 firmware. It is a good time to quickly backup your SHSH blobs with iFaith locally before its too late.

Backing up your SHSH for iOS 6.1.3/6.1.4 gives you the ability to downgrade your firmware in the future in case you got sick of iOS 7. This is mostly useful to iPhone 4 owners.

Well, you can downgrade your device to earlier versions of iOS like 6.1.2, 6.1.1, 6.1, 6.0 and even 5.1.1.

Please follow the steps below carefully. Don't skip any step. Also, make sure that you have all the requirements below.

Feel free to drop comments on your success story and issues that you might have encountered and i will try to help resolve it

Jailbreak And SHSH blobs

Jailbreak and SHSH blobs can be very confusing for some people especially those that are new to the Apple world.
Knowledge they say is power. If you have knowledge and understanding on a particular topic you won't have issues dealing with that topic.
 

At the time of this writing, it is not recommended to update your iDevice to iOS 6.1.3 if you intend on jailbreaking your device untethered. Furthermore, save your SHSH blobs with the software listed above.

However, if you do not plan to jailbreak your device, feel free to update to the latest iOS version.

Apple devices are one of the best kind of devices out there. Its so simple to use and relatively stable and reliable but there things you need to know when using an Apple device. Continue after the jump.
 This piece is especially recommended for those that are new to using Apple devices and are wondering what all these terms means.

Jailbreak 
Jailbreak is an activity that involves the running of certain programmed codes on an Apple device in other to lift restrictions or boundaries on the Apple Operating System (iOS) placed by Apple while giving the user of the device super user or full access to the device's system. Jailbreaking allow one to run unsigned applications that naturally would not run if it wasn't jailbroken.
There are 3 kinds of jailbreak: Tethered, Semi-tethered and Untethered

Tethered: device will not boot up until its jailbroken again whenever device goes off
Semi-tethered: Some apps will not function when device is turned off/on again until a jailbreak is performed on the device
Untethered: device will perform well, apps will run well if device is turned off/on - no need to re-jailbreak
Untethered jailbreak is the most preferable form of jailbreak.
Brand new Apple device are not in a jailbreak state. Apple frowns at it. As far as Apple is concerned it voids your warranty whenever you jailbreak your device. However, used devices bought may already have been jailbroken. 
One of the ways you can know if a device is jailbroken is by the Cydia  icon on the home screen
Benefits: it gives you total control over your device and you can install whatever you please on the device

Software that help to jailbreak Apple products are numerous but the most popular ones are

Evasi0n
evasi0n-icon-evad3rs 

Redsn0w
redsn0w app icon 

Snowbreeze
Updated Sn0wbreeze 

Absinthe
Absinthe jailbreak logo

At the time of this writing. Evasi0n is the tool recommended to jailbreak untethered iOS 6.0 - 6.1.2 on all devices.
Redsn0w is able to perform a tethered jailbreak on iOS 6.0 - 6.1.3 on selected devices
    Downgrade
    Downgrading refer to a process of Installing an earlier version of Apple's iOS on a device instead of the most current iOS.
    Usually, whenever, a new iOS is released, it becomes impossible to install a previous version of the iOS. However, ways have been designed to make this possible provided SHSH blobs have been saved for that iOS one intends to install.

    Downgrade is only possible for pre A5 devices. This means that iPhone 4S and 5  are not possible to downgrade. For example, an iPhone 4 with iOS 6.1.3 installed can be downgraded to iPhone 4 6.1.2 if the SHSH blobs are saved. However, iPhone 4S can't achieve that even if SHSH blobs are saved.
    Furthermore, apart from the firmware or iOS downgrade, there is also a downgrade of something called baseband. Just like the iOS downgrade, baseband downgrade is only possible for iPhone 3G and 3GS but not possible for later generation of iDevices.

    SHSH Blobs
    This is a kind of file saved on all devices whenever an iOS is installed on  the device. Its a kind of signature that  accompanies all iOS that are installed on a device.
    This file is also store on Cydia server for those that have a jailbroken device but can also be saved on a computer with the help of softwares like iFaith and TinuUmbrella.
    The benefit of having saved SHSH blobs is that it gives certain devices (pre A5 devices only) the ability to downgrade their iOS in the future if they so please even if Apple isn't signing it on their servers anymore.

    The recommendation is that one should always save SHSH blobs locally with the help of iFaith and TinyUmbrella just in case there is a need to downgrade iOS.
    That is, when you upgrade your iOS, do a saving of the device's SHSH blobs and keep on your computer.


    At the time of this writing, it is not recommended to update your iDevice to iOS 6.1.3 if you intend on jailbreaking your device untethered. Furthermore, save your SHSH blobs with the software listed above.

    However, if you do not plan to jailbreak your device, feel free to update to the latest iOS version.

    More terms would be added to the list. However, it is pertinent to note that proper information is needed before you upgrade to any firmware or attemp to jailbreak any iDevice .

    feel free to ask questions on any term you do not understand and any task you are not sure of carrying out.

    How to downgrade iPhone 3GS Baseband

    For one reason or the other one need to downgrade baseband. As of this writing, iPhone 4/4S/5 can't have their baseband downgraded once upgraded through a stock IPSW restore.
    However, iPhone 3GS can have its baseband downgraded.

    Follow these steps to achieve a baseband downgrade for the iPhone 3GS.

    Step 1
    Download the latest version of Redsn0w on your computer and extract to your desktop.

    Step 2
    If your device is on iOS 6.1 or 6.0.1, you will still need to download 6.0 IPSW because that is what Redsn0w can support for now. Connect your device to the computer and let Redsn0w detect it.
    It will also notify you of the device's bootrom and firmware version just at the bottom of the window

    Step 3
    Click on Extras, click on Select IPSW menu and the select iOS 6.0 IPSW that you downloaded. If you have a newer bootrom 3GS click yes

    Step 4
    Go back and then select Jailbreak. Kernel will be patched and then a window will appear where you will check "Downgrade from iPad baseband". Check it

    Step 5.
    Put your phone off and follow the instructions to enter into DFU mode.
    Once in DFU mode, Redsn0w will proceed with the jailbreak and downgrade of your baseband.

    Step 6
    Once done, the remaining process will conclude on your device. Your device will reboot and your baseband will be downgraded.

    Step 7
    Go to Cydia to download ultrasn0w fixer and ultrasn0w 1.2.7 to unlock your device

    That's it folks. Hope this helps someone. Leave a comment if you have any question.
