The legacy community is still alive and kicking thanks to the new tools that developers keep releasing. Here’s yet another tool called Geekgrade, which allows you to downgrade A4 devices without SHSH Blobs.

What is GeekGrade?

GeekGrade is a tethered downgrade utility for devices using Apple’s A4 processor. It is developed by LazyDevTeam member Damien along with other developers.

What this does is, it allows you to downgrade your A4 device to iOS 6 or below from any latest version. You don’t need a jailbreak or SHSH Blobs to go back.

It is not a utility per se because it works via iTunes. It’s very simple to use and all you need to do is tap Shift+Restore and you are all set!

Step 8 Wait for a few seconds and iReb put your device in pwned DFU mode.

Step 9 Open iTunes 11.0 and it will detect your device in DFU mode. Simply press the Shift key and click on Restore.

Step 10 Select the appropriate GeekGrade file for your target firmware and click Open.

Step 11 iTunes will now begin downgrading your device by restoring it to the older version. Wait for about 10-15 minutes until your device in Recovery mode.

Tethered Boot 

The downgrade part is now over and you now need to perform a tethered boot to boot your target version.
