TSSChecker is a useful tool developed by tihmstar for saving SHSH2 blobs of an iOS firmware so that you can later on downgrade to that firmware once Apple stops signing it. Last week, iPhone 7 and iPhone 7 Plus users were met with disappointment when the developer discovered that the SHSH2 blobs generated for the aforementioned devices were invalid.
Apparently, there was an issue with the tool that generated incorrect SHSH2 blobs for iPhone 7 and iPhone 7 Plus. But the good news is that tihmstar has fixed that issue in the latest version of TSSChecker, so you can now go ahead and use the tool to save the correct SHSH2 blobs for these devices.
As of this writing, Apple is signing iOS 10.2 so you can only generate SHSH2 blobs for this firmware only. If you had saved iOS 10.1.x SHSH2 blobs previously for iPhone 7 using the old TSSChecker version, then unfortunately they are not valid.
The fact that tihmstar quickly worked on this issue and released an update in just a week is an indication that this tool will hopefully receive regular updates in the future to fix new issues as well as support new iOS firmwares and devices.
If you have an iPhone 7, iPhone 7 Plus or an older iPhone model, I would highly recommend that you save the SHSH2 blob for iOS 10.2. Although Luca Todesco has stated that a jailbreak for this firmware is not planned at the moment, you never know when they will come in handy.
If you don’t want to go through the hassle of saving SHSH2 blobs using TSSChecker’s command line tool, then you can save it from TSSSaver website which is very easy to use.
The current beta of Yalu jailbreak supports iOS 10.1 – iOS 10.1.1. The jailbreak is not stable and contains a number of issues that could create problems on your device. It is recommended that you stay put and wait until Luca releases a stable version of this jailbreak. We will keep you updated as soon as this happens.Like this post? Share it!
