A few days back, Apple launched iOS 10.2.1 assuming to repair some minor bug. While iOS 10.2 is still being signed, it won't be long before Apple closes the signing window for this firmware.

We strongly suggest that you save your SHSH2 blobs for iOS 10.2 before its to late. Blobs can just be produced for firmwares that are still being signed by Apple. If the iOS 10.2 signing window is closed, you can no longer save its SHSH2 blob and this suggests that you cannot upgrade or downgrade to this firmware using tools like Prometheus.

Even if you're jailbroken, it's still best to conserve the SHSH2 blob for iOS 10.2 so that you can upgrade to this firmware without being required to upgrade to the current iOS firmware. There are no jailbreaks presently for iOS 10.2.1 and iOS 10.3, which is why it is very important that you take action now and don't miss chance to conserve your blobs for iOS 10.2 ( the window is closed ) as Luca's Yalu tool has been able to jailbreak this version

iOS hacker tihmstar has actually announced that he plans to launch a brand-new tool called Prometheus, which will allow users to downgrade or upgrade to an anonymous iOS firmware version.

He had likewise launched a brand-new tool called tsschecker which enabled you to save.shsh2 blobs, which would be required by Prometheus to downgrade or upgrade to an anonymous iOS firmware variation.


A reddit user "1Conan", has actually stepped up and developed an online tool called auo-tsschecker that will conserve you the trouble of executing the commands and will instantly save the.shsh2 blobs for you for the currently signed variations.

To use the online tool, you need the ECID and your iPhone, iPad or iPod touch's device identifier.

How to get your iPhone, iPad or iPod touch's ECID

  • Plug your iOS device to your PC or Mac.
  • Launch iTunes and click on Summary.

  • Select your device type i.e. iPhone, iPad or iPod touch.
      • Next, enter your iOS device's identifier, you can simply download this free app from the Appstore called CPU identifier on your device and voilaa.

The very best part of the technique is that it will save the.shsh2 blobs immediately for you for any brand-new iOS version Apple may release in the future, so you don't need to go through the inconvenience of saving it by hand whenever Apple releases an upgrade.
