Recently, iOS hacker tihmstar has announced the upcoming release of his tool Prometheus that allows you to
downgrade and upgrade unsigned iOS firmware version of iPhone, iPad and iPod
touch by which you will always be able to jailbreak your device at any time
even after Apple stops signing window.
For this, you must save your blobs in
a new format called .shsh2 using tihmstar’s
tool called tsschecker

How to save .SHSH2 Blobs for iPhone, iPad or iPod touch for Prometheus with tssaver Go to https://tsssaver.1conan.com.Paste the converted hexadecimal ECID you had copied above. Select your device type i.e. iPhone, iPad or iPod touch.
To save .shsh2 blobs for downgrading and
upgrading an unsigned iOS firmware like iOS 10.1, iOS 10.1.1, you first need to go to tihmstar’s
GitHub
 and download tsschecker tool which supports Mac, Windows
and Linux.
And thankfully, 1Conan, a reddit user
has carried out and created an online tool called
auto-tsschecker that allows you to save .shsh2 blobs for Prometheus to
downgrade or upgrade an iPhone, iPad and iPod touch to an unsigned iOS firmware
version like iOS 10.1, iOS 10.1.1. Please note that saving .shsh with TinyUmbrella will
not work for Prometheus.

However you
can easily save .shsh2 blobs with TssSaver which allows you to
Downgrade/Upgrade Unsigned iOS Firmware Version . To use the online
tsssaver, you need the ECID and an iPhone, iPad or iPod touch’s device
identifier.
Here’s How to find ECID of your iPhone,
iPad or iPod touch
  • Launch iTunes and Connect your iOS
    device to the computer with lightning usb cable.
  • Click on Summary in the left-hand
    pane.

  • Click on the Serial number field in the
    Summary tab until you see the ECID.
  • Now Right-click on it and copy it to the
    clipboard.

Please note that decimal ECID which
you have copied earlier, it will not save the correct .shsh2 blobs for iOS 10.1.1 for
downgrading and upgrading with Prometheus tool. 

For this, you need a
hexadecimal ECID and to convert the decimal ECID into hexadecimal you can use
