Install Kindle HF

Package: gzreader-kindlehf-<version>.zip — for any Kindle on firmware 5.16.3 or newer: the Paperwhite 3 (tested), and untested: Paperwhite 4, 5 and Signature Edition, Paperwhite 6, Kindle 2019, 2022, 2024, Oasis 3, Scribe, Colorsoft (shown in greys). Built on KOReader's kindlehf package (hard-float, for the newer system libraries).

On firmware 5.6.1 – 5.16.2.x take the kindlepw2 package instead. The firmware version is in Settings → Device Options → Device Info.

1. Jailbreak

Use the method kindlemodding.org's Jailbreak Wizard names for your Kindle and firmware: Jailbreaking and rooting → Paperwhite and newer. Newer firmware is patched against older methods, so check before updating a jailbroken Kindle: one updated past what any jailbreak handles can't be jailbroken until a new method comes out (and can't be downgraded without one).

2. Download

From the latest release, take gzreader-kindlehf-<version>.zip.

3. Copy it to the Kindle

1. Connect the Kindle to the computer with USB; it shows up as a drive.
2. Unzip the package on the computer. Inside are the folders koreader, extensions and documents (with one file, GZreader.sh).
3. Copy those folders to the top of the Kindle's drive, merging with what's there (your books stay). If an old KOReader is installed, its koreader folder is replaced.
4. Eject the Kindle safely and unplug it.

4. Start GZreader

• Tap the GZreader item with GZreader's logo on the Kindle's home screen (documents/GZreader.sh, a scriptlet, which the current jailbreaks run).
• Or, with KUAL: GZreader → Start GZreader.

The setup guide runs on the first start (After installing), followed by a short tour of the quick panel.

Notes for these Kindles

• Touch throughout. → Using GZreader → Touch Kindles
• Kindles with a frontlight get a light slider in the quick panel; those with a warm light (Paperwhite 5 and newer, Oasis 3, Scribe, Colorsoft) also a warmth slider, Cool to Warm. → Using GZreader → Touch Kindles
• These Kindles have no speaker or headphone jack (the newer ones play audio over Bluetooth only, which GZreader doesn't use): audiobooks, music and read aloud aren't offered.
