Setting Up A Hotfix

A hotfix allows your Kindle’s jailbreak to persist after updating. There are two different hotfixes and which one you need to install depends on which method you used to jailbreak your Kindle.

If you installed OTARenamer, make sure to uninstall it beforehand or the hotfix will not be detected by the Kindle

Hotfix Won’t Install

There is a good chance that after installing an older version of Hotfix you disabled OTA updates, meaning the Hotfix update file will be ignored!

Follow these steps to update the Hotfix:

1. Activate airplane mode
2. Enable OTA update (KUAL -> Rename OTA binaries -> Restore)
3. Follow the Hotfix installation instructions above
4. Disable OTA update (KUAL -> Rename OTA binaries -> Rename)

Now that we have our hotfix setup, we can install KUAL and MRPI
