Developer-Tihmstar has released TSSChecker tool that allows users to save SHSH blobs of iOS 10 beta version for the iPhone/iPad.
If you have a jailbroken iOS device, having your SHSH blobs saved will give you the ability to downgrade back to the previous firmware in case you accidentally upgrade to a newer iOS version which is not jailbroken yet.
Most of us are waiting for the new jailbreak tool. However, it will be a long time to release the tool. According to the creator of TSSChecker, saving your iOS 10 beta blobs could be important in future.
How to Save iOS Firmware Beta Blobs
Before we begin, there are some materials you have to download
iPod touch 6 – Model A1625
After that, see the instructions below.
Step 1: When your iOS 10 IPSW completes downloading, change its extension to .ZIP file and unzip it.
Step 2: Look for a file called BuildManifest.plist
Step 3: Create a folder name TSS and drop both TSS Checker and the BuildManifest files in there
Step 4: Open Terminal and type in: cd (grab and drop your folder in step 3) then press return
Step 5: Copy and paste this: ./tsschecker -d device model -s -e device ECID# -m BuildManifest.plist
Step 6: Press return again
Device model should look like example
‘##iPhone7,2 no space between the device or model number’
Once you have done all of that, your SHSH blobs should be saved. If you get any troubles, please leave your comments below.
