In this step by step article, I will let you know how you can save SHSH2 BLOBS. Saving Blobs which are the hashing formulas are really necessary to downgrade iOS version in the future if certain conditions are met. Currently, there are only two versions which are currently signed by Apple iOS 12.1.1 and iOS 12.1. This means that you can go to these versions without any restrictions on your iPhones, iPads, iPod touches, and Apple TVs after you save the blobs for these.
The jailbreak usually is for those iOS versions which are not currently signed. In order to get some protection for your device, you need to save the blobs. This will allow you to downgrade or upgrade in certain conditions in the future to a better and stable iOS version which is jailbroken.
For saving your blobs for an iOS version that version must be signed. This means that we can not save shsh blobs for the versions which are already unsigned by Apple. In our case, we only can save shsh blobs for iOS 12.1.1 and iOS 12.1.
Save SHSH2 blobs
For saving your shsh2 blobs you need to use a tool called TSS (TATSU Signing Server) Saver here is the link to it.
- Step 1:
Open this in your mobile phone or computer. This tool lets you check the blobs which are valid which you have already saved. Also, this tool lets you retrieve the shsh2 blobs that you already have saved.
- Step 2:
Connect your device to iTunes for which you want to save shsh2 blobs. There you see the Serial Number, click twice on that and ECID number will be shown there. See in the pic below, then you need to copy that.
- Step 3:
Paste that ECID number in Tss Saver tool and also select the device type and the device generation which you are using carefully. After that hit the submit button.
Now you have saved your shsh2 blobs. See below you’ll be redirected to this page and here is a link, if you go to this page it’ll show you the latest and the previous SHSH blobs you have saved.
Retrieve SHSH blobs
In case you want to retrieve the blobs, you need to enter the ECID number into the Retrieve section. After entering the number and pressing get your blobs button. After that a page will appear showing all the blobs
This is how to save shsh2 blobs for later downgrade and upgrade iOS versions.
