Kindle Factory-Firmware Jailbreak Guide (Firmware<=5.8.7)

This method comes from MobileRead. The idea: first flash a factory firmware onto the Kindle, then jailbreak that firmware. You must have a factory firmware matching your current firmware version — for example, the Oasis 2 only has factory builds for 5.9.0.5.1 and 5.9.0.6, so other versions (like 5.12.1) cannot be jailbroken this way.

Risk notice: Jailbreaking is risky — back up important Kindle data (usually the documents folder) first to avoid losing it. You are responsible for any consequences.

Part 1: Check the requirements

First confirm your Kindle serial's first 6 digits are in the jailbreakable list (see the MobileRead serial number table), and follow these rules:

• The Kindle is registered to an Amazon account.

• The battery is fully charged.

• Special Offers are turned off.

• Device password and Parental Controls are disabled.

• Airplane Mode is on (offline).

Note: Each step below only needs to be done once; delete leftover files after a step completes.

Part 2: Install the factory firmware

Download the factory firmware matching your current firmware (a lower current version is fine). First check the firmware model matches your device, then confirm your current firmware ≤ the factory firmware's version; if it's higher, there is no usable factory build. Even if your version equals the factory build, you must still flash it to jailbreak.

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

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

Part 3: Jailbreak the factory firmware

Pick the section for your device.

Kindle Paperwhite 2 (KPW2)

Download kindle-jailbreak: Official page ｜ Baidu Netdisk

1. Unzip kindle-jailbreak-x.xx.N-rxxx.tar.xz, then unzip kindle-5.4-jailbreak.zip.

2. Connect via USB and copy all extracted files to the Kindle root.

3. Eject, then tap Menu → Settings → Menu → Update Your Kindle.

4. Nothing visibly happens for a while — don't touch the device until **** JAILBREAK **** appears at the bottom of the screen. That means success.

KO 1/2, KV, KPW 2/3/4, Kindle 7/8/10

Download kindle-jb-factory: Official page ｜ Baidu Netdisk

Factory firmware < 5.11:

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

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

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

4. The screen flashes and the device restarts — continue to Part 4.

Factory firmware ≥ 5.11:

1. Unzip to get Merchant.zip.

2. Connect via USB, copy Merchant.zip to the root, and eject.

3. Type ;merchant (semicolon included) and press Enter.

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

Note: If you plan to update to the latest firmware, don't install plugins first — the jailbreak survives updates, plugins don't. If nothing above works, ask in the original thread.

Part 4: Install the patch

Before updating to the latest firmware, install the latest JailBreak Hotfix to keep the jailbreak; also disable automatic updates.

Download JailBreak-hotfix: Official page

1. Connect via USB and unzip JailBreak-1.15.N-FW-5.x-hotfix.zip to get Update_jailbreak_hotfix_1.15.N_install.bin.

2. Copy the .bin file to the root and eject.

3. Tap Menu → Settings → Menu → Update Your Kindle and wait for the restart.

4. You can now update to the latest firmware and keep the jailbreak. If you reset the device, use a restore file to recover the jailbreak.

Part 5: Related resources

• Installing plugins: see the plugin installation guide on this site.

• Recovering the jailbreak and plugins after a reset: see the recovery guide.

• When reporting an issue, include your serial prefix, firmware file name, and what you did.

Part 6: FAQ

• How do I verify the jailbreak? Create RUNME.sh at the root with #!/bin/sh and eips 0 0 'Hello World!', save it, then run ;log runme; if Hello World! appears top-left, the jailbreak works.

• How do I remove the jailbreak? Just reset the Kindle (back up documents first).

• Can I delete the copied files? Manually copied files can be deleted after the related step; files/folders generated by the process should be kept.

• How do I block auto-updates? Airplane Mode, manual updates, disabling WiFi auto-download.
