Updating and Uninstalling

Updating

GZreader checks for a new release once a day (while Wi‑Fi is on) and offers it; or open Settings → General → Updates, or the quick panel → Updates. Updating keeps your books, settings, connections and reading progress, and a What's new screen shows what changed. Installing a newer package over USB the same way as the first time also works.

• Kindle 2 and DX (no Wi‑Fi): the sync page brings new versions with the sync.
• Nooks: over Wi‑Fi as on a Kindle; a new KOReader version needs the full package pushed again.
• Test builds: Settings → General → Updates → Test builds gets changes before they're released.

Uninstalling

Kindles: delete the koreader folder, extensions/koreader, launchpad/koreader.ini (Kindle 2/3/DX) and documents/GZreader.sh (Kindle 4 and newer). The GZreader folder with your books stays until you delete it.

Nook 1st Edition: remove the icon's helper and app first (adb shell sh /data/gzreader/launcher.sh uninstall, adb uninstall gzreader.nook.launcher), then adb shell rm -r /data/gzreader, and on the microSD card (or the Nook's own storage) the .gzreader-app folder. The GZreader folder with your books stays until you delete it.

Nook Simple Touch: adb shell rm -r /data/gzreader, and the .gzreader-app folder on the card or the NOOK drive.

Neither Nook's system is changed for good by running GZreader: restarting the Nook always brings back its own software.
