TinyUmbrella is a software program that allows you to compile and save SHSH encryption signatures for previous versions of Apple firmware so you can restore to those versions to your iPod or iPhone. TinyUmbrella is written in Java, so you can install it on any machine that has a version of Java installed, including Windows, Mac and Linux machines. TinyUmbrella runs independent of iTunes, so you can restore older versions of firmware using a Linux machine, even though iTunes does not have a Linux version. The TinyUmbrella version for Linux is not supported.

Step 1

Download the JAR archive file for TinyUmbrella on your Linux machine. The most current version for Windows and Mac may be newer than the most current stable version for Linux.

Step 2

Open a terminal window. In Ubuntu, the most popular Linux distribution, hold down the "Ctrl" and "Alt" keys simultaneously, then tap "T" to launch the terminal window.

Step 3

Enter "sudo apt-get install sun-java6-bin, sun-java6-jdk" in the terminal window without quotation marks to install Java on your Linux machine. This command may differ depending on which Linux distribution you are running. Enter your password when the prompt comes up. Press the "Y" key when the Java license agreement comes up to accept it.

Step 4

Enter "cd ~/downloads" in the terminal window to enter the downloads folder in your Home folder. This is the default folder for downloads. If you downloaded TinyUmbrella into a different folder, use the "cd" command to navigate to that folder instead.

Step 5

Enter "java -jar tinyumbrella-4.21.05.jar" to run the TinyUmbrella installation wizard. Allow the installation to complete before running TinyUmbrella.
