This page will guide you through setting up KUAL (Kindle Unified Application Launcher) and MRPI (MobileRead Package Installer) to install and use homebrew on your Kindle.

Info taken from the original thread: https://www.mobileread.com/forums/showthread.php?t=320564

Note that KUAL (Booklet) and MRPI depends on each other, so you will have to install both of them at the same time.

Prerequisites:

• KUAL and MRPI, download them from NiLuJe's snapshot thread.

  • There are multiple variants of KUAL as it is designed to run across the entire range of Kindles. For which variants to pick for your Kindle:

    • For FW 5.9 and newer, use KUAL Booklet (coplate) variant.

    • For FW 5.8.x and older, use KUAL Booklet variant.

Installation for KUAL Booklet variants:

1. Connect your Kindle to your PC.

2. Extract MRPI's extensions and mrpackages folder to Kindle's visible storage's root. This is where the document folder resides.

3. Drop the KUAL files in.

   • Using KUAL Booklet or KUAL Booklet (coplate), drop KUALBooklet_*_install.bin into mrpackages folder.

     • To identify which is which, Booklet (coplate) variant will have a commit string in its version number in the file name, such as KUALBooklet_ff4134d_install.bin, while Booklet will have the version number in its file name, such as KUALBooklet_v2.7.29_install.bin.

4. (Optional) Drop any other extensions into the extensions folder, and update bins into mrpackages folder.

5. Once everything is in place, eject/disconnect your Kindle, then enter ;log mrpi to start MRPI. Hush, little baby... should pop up at the bottom half of the screen.

   • If nothing happens, check and make sure you've placed everything in place correctly.

   • If for whatever reason ;log doesn't exist, You can still install by dropping Update_KUALBooklet_hotfix_*_install.bin into Kindle's visible storage's root, then go into Settings > Update Your Kindle to install it.

     • Obviously this won't work if your Kindle firmware is too new, and the package hasn't been updated, in which case you'll have to wait for an update.

Once you've completed the steps, feel free to head onto Disable OTA Updates for 5.11+ (optional, but recommended), or head to Installing KOReader (optional).
