Remember, I told you about a GUI version of FutureRestore was in the works? Its developer has just made it public and here’s how you can download it.

What is Prometheus?
Prometheus is a new GUI version of the FutureRestore utility by Tihmstar. It is developed by hacker Jake James.
You can downgrade and upgrade your iOS devices with a more user-friendly interface. Needless to say, you will still require proper SHSH Blobs to go with it for a successful restore.
It works only with 64-bit iPhone, iPad, and iPod touch devices. Here’s how it looks like in action.
Does Prometheus work with Windows and Linux?
No, it only supports macOS only and is incompatible with Windows and Linux.
The main reason behind this is the incompatibility of FutureRestore with Windows. Since this is only a GUI and not a standalone tool, it inherits those properties from the base utility.
As you already know, the original FutureRestore tool is compatible with Linux but this one isn’t. However, it doesn’t mean that it is impossible.
The developer has already hinted that a Linux version is certainly possible. With that said, some other developer will have to work on the port since Jake doesn’t have enough experience with Linux utilities.
Here is the direct download link for this GUI utility. You also must follow the installation tutorial given below as the developer’s tutorial is only for advanced users.

How to Install Prometheus
Step 1 Download Prometheus-master.zip file using the direct download link given above.
Step 2 Put the Prometheus.app file inside the Applications folder.
Step 3 Now navigate to Applications > Utilities and open Terminal.
Step 4 Enter the command given below.
Step 5 Drag the install.sh file into the Terminal window and press the enter/return key.
Step 6 Perform step 5 once again.
Step 7 The tool will now run. You will receive this error at the very beginning – “It is recommended to switch debug mode on”. Simply click OK and move on with the restore.
If you get errors while using install.sh, update your XCode to the latest version, that is, XCode 9 beta.
For updating FutureRestore, perform step 5 again. If you want to update Prometheus, simply download it from the link given above and then follow the installation tutorial.
This is the perfect time to actually upgrade or downgrade your device if you haven’t already. This tool is surely a good start and hopefully will be ported to Windows soon.
The point is a Windows versions will benefit a lot of users, who otherwise will never be able to use it. If you want Windows compatibility, contact Tihmstar.
With Adam Dodenfeld’s exploits just around the corner, such a tool is certainly indispensable for all users who are currently on iOS 10.3.1 or below.
If you experience errors while installing this tool, just leave a comment below.

I’m getting this on 10.12.6 MacOS.. I hope someone has an answer. I’ve done installed latest Ruby, and ‘brew update’. I ran install.sh twice (and more) and can get by without any errors but I’m still getting this:

Why don’t you use the latest version of FutureRestore? This version is outdated.
Tried the steps, application didn’t launch. Stating that “Prometheus quit unexpectedly”. Any suggestions?
Hello, Ricco. Can you send me a screenshot? If this doesn’t work, you can always try the terminal version.
