A couple of days ago, word got out that iOS developer tihmstar has been working on a tool called Prometheus. What it does is very essential to jailbreaking older iOS devices with OS versions that Apple does not sign any more. It allows devices to downgrade and upgrade to non-signed iOS versions by saving the crucial .shsh2 blobs required to do so.
With Luca Todesco indicating that he will drop a public release of iOS 10.1.1 jailbreak on top of Ian Beer’s dev-level exploit for iOS 10.1.1, Prometheus promises to be a tool that every jailbreak enthusiast will find extremely useful. Even those waiting for that elusive Pangu iOS 10 jailbreak should definitely get the tool as soon as it is released.
[UPDATE 12/22: Todesco’s Yalu iOS 10 / 10.1.1 Jailbreak Beta 3 is Here! Download Now, Tutorial Link Included]
Prometheus will be made available on New Year’s Eve, but ahead of the public release, tihmstar has released a companion tool called tsschecker that allows you to save your .shsh2 blobs in advance. Unfortunately, you’ll need to have developer skills to navigate through it, but the good news is, Redditor 1Conan has a new online tool that he’s calling, simply, TSS Saver, that basically accomplishes the same task.
The biggest benefit of this tool is that it will allow you to later use Prometheus to move up or down the OS version history without worrying about whether or not Apple is signing it at that time. That means you can save your iOS 10.1.1 .shsh2 blobs now and confidently upgrade to iOS 10.2, because if Luca Todesco does release an iOS 10.1.1 before the year is out – or even after that – you can still downgrade to iOS 10.1.1 even if Apple isn’t signing the version by then.
TSS Saver is much easier to use than tsschecker, and doesn’t require you to have deep technical knowledge. Here’s a step-by-step guide to save your blobs for any currently signed version of iOS for future use, when a jailbreak is made available for that particular version.
Note: You’ll need a 64-bit jailbroken device to use TSS Saver.
Step 1 – Preparation
First of all, here’s what you need: your jailbroken device, a lightning cable and a Mac or PC running the latest iTunes version. You’ll also need your ECID number, which you can find after plugging in your device to the machine.
On iTunes, click on the Summary tab on the left, and then click on Serial Number until it shows your ECID just below your phone number. You’ll also need the Model Identifier, which you’ll see if you keep clicking on Serial Number.
Once you have these two bits of data, copy them to your clipboard or write them down (better). Redmond Pie says if you have iOS 10 on your device and macOS Sierra on your machine, it will be available on both devices through Universal Clipboard, but they probably missed the fact that iOS 10 doesn’t have a jailbreak yet, which is a pre-requisite for using TSS Saver!
Note: Your ECID may be displayed as a decimal number. TSS Saver does accept this format as well, but make sure the right option is selected. Here’s an online conversion tool you can use to convert the number if required – Decimal to Hexadecimal converter online.
Step 2 – Using TSS Saver
Once you have both numbers, head over to https://tsssaver.1conan.com/ and you should be able to see this:
Step 3 – Getting Your .SHSH2 Blobs
Once you’re in, simple enter the ECID, choose the correct Model Identifier, check the “I’m not a robot” checkbox and click the small ‘Submit’ text.
After processing the information, TSS Saver will take you to a page where you can download the .shsh2 blobs you need for your devices. You can do this multiple times if you have more than one device that you want to jailbreak at a later time.
And if you lose your .shsh2 blobs after you download them, no problem: you can get your download links again from TSS Saver in the “Lost your link?” section.
The service is absolutely free, but 1Conan does ask that you contribute in order to keep the servers working. You can make a direct payment to his PayPal account – email@example.com.
And you’re done! Now that you have the .shsh2 blobs that you need, once Prometheus comes out, you’ll be able to easily upgrade or downgrade to unsigned iOS versions.
