TinyUmbrella iOS 8.2 Release Of New Beta Update

The new beta update version for TinyUmbrella iOS 8.2 fix release was developed by creator Semaphore aka @notcom. With this tool users will be able to save iOS 8.2 and iOS 8.1.3 SHSH blobs.

Semaphore claims that he has rewritten TinyUmbrella from the ground up, and now it is a lot more easier to use the tool.

Apple company allows users to restore to the latest iOS versions only to prevent from downgrading to an older iOS version, which would have made it easier to jailbreak the iOS device. As the example, in case the company allowed users to downgrade their device, they could downgrade back to iOS 8.1.2, which can be jailbroken using TaiG and PPJailbreak.

Apple stops signing the firmware files, it just doesn't providing SHSH blobs for older iOS versions.

TinyUmbrella iOS 8.2 release allowed you to save the SHSH blobs, so you could use it to create a pre-signed IPSW file, which will be able to restore your device with an iOS version that company was no longer signing.

The TinyUmbrella new version now saves the SHSH blobs automatically for your device, and also you get the option to save the ‘OTA’ SHSH blobs for all devices.

Due to Semaphore report it maybe possible to downgrade to older iOS version using the SHSH blobs. It will be really great if he could do it. Users will be able to  downgrade to iOS 8.1.2, for an example, using a custom IPSW firmware file using the SHSH blobs, will ensure that the iOS device can always be jailbroken. It will be useful especially until a jailbreak for the latest iOS version will be launched.

Downgrade iOS 6.1.3 to iOS 5.0.1 on iPad 2 and iPhone 4S

The popular iOS developer and researcher, iH8sn0w, who is responsible for the creation of Sn0wbreeze, iReb, iFaith and also f0recast has been working hard again attempting to resolve a problem that has been tainting the experience of the iPad 2 and iPhone 4S owners. The hacker has found the exploit that will allow A5 device users to downgrade iOS 6.1.3 to iOS 5.0.1.

The iPad 2 and iPhone 4S are run by the A5 processor, and as any jailbreak fan knows, it hasn’t earlier been possible to perform firmware downgrades on these two devices. When Apple launches a new version of iOS, they quickly stop signing the older firmware, which means that any official restores result in the user setting up the newest official iOS version onto their gadget.

In typical situations, going to the newest iOS 6.1.3 is not actually a big problem for standard users. Nevertheless, the issue takes place when iDevice owners who want to perform a jailbreak update their software, leaving them having to wait with patience till the Dev-Teams create a working, distributable jailbreak for that fresh iOS version.

On older gadgets, users can usually benefit from a firmware downgrade to versions of iOS that Apple no more signs once they have the relevant SHSH blobs saved for that firmware.

Cydia automatically grabs any available blobs and update the users’ Cydia app using the blobs that have been saved. Jailbreak fans additionally use the popular and highly effective TinyUmbrella tool in order to quickly and efficiently get available SHSH blobs and save them locally on their devices for use later on.

Even though we've had the iPad 2 since March 2011, and the iPhone 4S since October, there has not been a method available to let users downgrade iOS 6.1.3 to iOS 5.0.1 on these A5 powered devices meaning that a restore is necessary for any reason that the newest firmware version would be installed.

Canadian iOS developer and hacker iH8sn0w states to have found a loophole in Apple’s APTicket system that helped him to successfully downgrade iOS 6.1.3 to 5.0.1 on his iPad 2.

The good thing is that he also believes that the loophole he has found will even allow firmware downgrades on Apple’s new iPad 3 running on the A5X processor. Of course this will only be possible when new firmwares become available mainly because that all new iPads were shipped with iOS 5.1, which is the current version.

The news simply means that the iPad 2, the new iPad and the iPhone 4S owners have finally been invited to the downgrade party and now they can downgrade iOS 6.1.3 to iOS 5.0.1.

Two Ways To Downgrade iOS 6.1.3 To iOS.6.1.2

After releasing of the new iOS 6.1.3 and new iPad from Apple everyone, who had updated its gadgets, needed to jailbreak iGadgets. Because by updating your iPad 2 or iPhone 4S to 6.1.3 you lost your jailbreak. So you can downgrade iOS 6.1.3 to iOS 6.1.2.

However if you are iPhone 4S owner then I don’t advice you to downgrade iOS 6.1.3 because it doesn’t work.

This is what was written on The iPhone Dev team blog:
If you have an iPhone 4S, the basic rule above is really the only rule:  you cannot restore back to 5.0.1 once the 5.0.1 signing window is closed, no matter what (even if you saved your SHSH blobs). 
If you have an iPad2 with saved 4.x hashes, you can in fact downgrade to that 4.x but you won’t be able to get to 5.0.1 once the 5.0.1 signing window is closed (even if you saved your 5.0.1 SHSH blobs).
So if you’ve upgraded to iOS 5.1 on A4 device mistakenly and want to downgrade to a lower iOS to get back the untethered jailbreak, we’ll show you how to do so. You’ll need SHSH blobs for the required iOS to be downgraded to to be saved on your computer or on Cydia.

iFaith can downgrade iOS 6.1.3 To iOS 6.1.2

NOTE: This method works for A4 devices only: iPhone 4, 3GS, iPad 1, iPod touch 4G, 3G.

STEP 1: Download iFaith and iTunes 11.0.3.

STEP 2: Run iFaith, and choose “Build *signed* IPSW w/Blobs” > “Build IPSW”.

STEP 3: Now browse for the SHSH blobs saved on your computer to downgrade back to iOS 6.1.2 or iOS 5. iFaith will ask you to select the IPSW firmware for the iOS you’re on it, select iOS 6. Finally iFaith will create a new custom firmware file for you on the desktop with SHSH blobs for the firmware you are downgrading to.

STEP 4: Head to iTunes, put your device in DFU mode and select the custom firmware created by iFaith on iTunes to restore.

Downgrade iOS 6.1.3 To 6.1.2 Or Below

NOTE: This method works for all devices except the iPhone 4S but including iPad 2.

STEP 1: Download iTunes 11.0.3 and you’ll downgrade iOS to iOS 6.1.2 or below.

STEP 2: Connect your device into your computer then use the latest redsn0w jailbreak tool to put your device in “Pwned DFU” mode under Extras.

STEP 3: Now you’ll need to edit the hosts file to trick Apple’s servers. Navigate to C:\Windows\System32\drivers\etc on Windows. On Mac, navigate directly to etc.

STEP 4: Now backup your hosts file anywhere on your computer then open it and this line at the end of the file.

STEP 5: After saving the hosts file, open iTunes and select your iOS device from the sidebar. While holding the Shift on Windows or Alt on OS X key, select Restore and choose the firmware file which you wish to downgrade to.

In some cases, iTunes will throw error 1013, just ignore it as it’s normal to happen while downgrading. At this point, your device will be in Recovery Mode with your desired version of iOS fully installed.

Step 5: Your should  be now in Recovery Mode, you can get out of this mode by downloading TinyUmbrella for Windows or for Mac OS X and selecting “Kick Out Of Recovery Mode”.

And now you your work is done. You’ve just downgraded iOS 6.1.3 to iOS 6.1.2 and earlier Apple OS on your gadget, so now you can easily to jailbreak it.
