Get Custom Screensavers on the Kindle 4 on OS X
Wednesday 21 March, 2012
This guide is for getting custom screensavers onto the new Kindle (Non-Touch) using Mac OSX.
The first thing you need to do is plug your Kindle into your Mac via USB. Then create a file with the name
ENABLE_DIAGS and make sure it has no extension (e.g. .txt, .jpg). Copy this file to the root of your Kindle and then eject. Now go into settings and restart your Kindle and it should enter diagnostics mode.
Once your in the diagnostics mode, go to
Misc individual diagnostics > Utilities > Enable USBnet and press the right arrow to confirm. You are now ready to create the folder you’ll need to add custom screensavers. Connect your Kindle to your Mac and open up network preferences.
On the left hand side you should see
RNDIS/…Gadget in the connections list. Select this and then change
Configure Ipv4 to “manually”. Change the IP address to
192.168.15.1. Now open up the Terminal (Applications > Terminal). From the terminal you will need to enter each of these commands one by one either by typing them out, or copying and pasting each one. I would suggest using this pastebin dump to copy from to avoid any weird issues. The root password is
mario, enter this when prompted (after the first command).
The commands you need to enter are as follows:
enter password if/when prompted
mntroot rw mkdir /mnt/us/screensaver mount /dev/mmcblk0p1 /mnt/base-mmc mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800.old ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
Now you can disconnect your Kindle and exit the diagnostics mode. To do this, simply press the right arrow to exit each menu until you see
Exit, Reboot or Disable Diags. Select this and then choose
Disable diags and confirm with the left arrow and your Kindle should reboot. Once your Kindle has rebooted, connect it back up to your Mac and open it in Finder. There should be a new folder called “Screensavers”. Simply put your custom screensavers in that folder and restart your Kindle. And voila, custom screensavers!
If you need screensavers, I found most of the ones I’m using from here. If you want to create your own, screensavers must be in .jpg or .png format and have dimensions of 600 x 800. Have fun!
