After my last post about custom Kindle firmwares possibly making appearance soon, I received several emails with questions on how official firmware updates should be applied. Indeed there is very little information in the User’s Manual on how to update the Kindle software.
Normally Kindle 2 would automatically download appropriate software updates if it is connected to the WhisperNet and automatically intall it when Kindle goes into sleep mode. Update installation will be followed by a reboot.
If you are don’t have Sprint EVDO coverage and therefore don’t have access to WhisperNet update can be done manually by following these steps:
- Download appropriate update file from Amazon.com. Kindle 1 updates should be downloaded from http://www.amazon.com/update_kindle.bin. Kindle 2 users should download from http://www.amazon.com/update_kindle2.bin. It’s very important not to mix these files as you can possibly brick your Kindle by installing the wrong update.
- Connect your Kindle to your PC via USB cable.
- Once Kindle USB drive is mounted copy the downloaded file to the root folder of it.
- Unmount the drive using Safely remove installed hardware icon in the system tray (next to the clock, volume control icon etc)
- Disconnect Kindle from the PC.
- Go to the Home Screen, press Menu and select settings and then select “Update Your Kindle”. If your Kindle is already updated the menu item will be gray and you will not be able to select it.
- Once update is installed your Kindle will reboot.
Please be extremely careful when following these instructions and even then do it at your own risk!
