Kindle Oasis 2 Jailbreak Guide: Firmware 5.9.0.5.1 / 5.9.0.6

Kindle Jailbreak Compatibility Quick Reference

Covers all current and discontinued Kindle models · Firmware version requirements for jailbreaking each model

How to check your firmware version: On your Kindle: Menu → Settings → Menu → Device Info, where you will see the "Firmware Version".

Before jailbreaking: To prevent your Kindle from auto-updating during the jailbreak process, it is strongly recommended to fill the storage to leave less than 100MB free and delete any .bin files from the root directory of your Kindle.

This jailbreak only applies to Kindle Oasis 2 (KO2) with factory firmware 5.9.0.5.1 or 5.9.0.6. Jailbreaking is risky — proceed at your own risk.

Note: Skip WiFi setup before you begin, or disconnect WiFi immediately if already connected, to avoid firmware updates.

The flow matches the factory-firmware method: install factory firmware → jailbreak → patch → update → install plugins.

Download the factory firmware

Confirm your KO2 shipped with 5.9.0.5.1 or 5.9.0.6; otherwise do not use this file:

Download update_kindle_oasis_9th_factory_5.9.0.6.bin: Baidu Netdisk

MD5:  18624db8c1838ec2b5b8bfb3406ac041
SHA1: 56eee3fb10ce3f71802bd6f34f8c05733d00bcff

Install the factory firmware

  1. Connect via USB and copy the factory firmware to the root (same level as documents).

  2. Eject, tap Menu → Settings → Menu → Update Your Kindle, and wait for the downgrade to finish.

Note: Installation can take 30+ minutes — keep the battery full and don't touch the device.

Jailbreak the factory firmware

To block auto-updates, create an empty folder named update.bin.tmp.partial at the root (no extension, empty).

Step 1: Jailbreak with kindle-jb-factory:

Download kindle-jb-factory: Official page

  1. Unzip kindle-jb-factory-x.x-rxxx.tar.xz to get main-htmlviewer.tar.gz.

  2. Connect via USB, copy main-htmlviewer.tar.gz to the root, and eject.

  3. Tap the search bar, type ;installHtml (semicolon, capital H, lowercase l), press Enter.

  4. A document named JailBroken appearing in the library means success.

Step 2: Install the JailBreak Hotfix:

Download JailBreak-hotfix: Official page

  1. Connect via USB and copy Update_jailbreak_hotfix_1.15.N_install.bin to the root.

  2. Eject, tap Menu → Settings → Menu → Update Your Kindle and wait for the restart.

  3. After reboot, firmware updates keep the jailbreak intact.

Note: After jailbreaking you can update to the latest firmware, but don't install plugins before the update — the jailbreak survives, plugins don't.
