From Linux, how do I update a K3 Kindle from 3.4 to 3.4.2 version?

This is a slightly different question than previous because it's Linux specific.

Because my device is:

Kindle Keyboard 3G (Free 3G + Wi-Fi)

Your serial number starts with "B006"

If you have software version 3.4.1, download Software Update 3.4.2.
If you have software version 3.4, download Software Update 3.4.2.

Just not sure exactly how to proceed once it's downloaded:

Amazon Device Support › Fire & Kindle Software Updates › Kindle Keyboard Software Updates› Transfer & Install Software Updates Manually

Software updates automatically download and install on your Kindle Keyboard when connected wirelessly; however, you can also manually download the software and update your device via USB cable.

Before you perform these steps, make sure you determine your software version. Go to Determine Your Software Version.

From your computer, go to Kindle Keyboard Software Updates and download the applicable software update file.
Transfer the software update file to your Kindle device:
    Turn your Kindle Keyboard on and connect it to your computer using the USB cable.
    Drag and drop the new update file from your computer onto the Kindle drive.

Note: Do not drop the file into one of the folders within the Kindle drive.
Monitor file transfer and disconnect:
    After the file has transferred successfully, eject the Kindle to safely disconnect your Kindle from your computer.
    Disconnect the USB cable from your Kindle and your computer.
Start the software update:
    From Home, press the Menu button, and then select Settings.
    Press the Menu button, and then select Update Your Kindle. This option will be grayed out if the most recent update has already

been installed or if the file transfer was not successful. Select OK to perform the update. Your Kindle will restart twice during the update. After the first update, you will see Your Kindle is Updating.

Obviously, the Kindle needs to be running to transfer files to it. But it also needs to have the screen locked. Yes? Then, just put the file in the root directory which is available?

    I don't understand the question. Unless you use a hardened Linux version, your Kindle should be automatically mounted as a USB partition, when you connect it to your Linux machine. Simply copy the .bin file that you downloaded from Amazon to the root partition of the Kindle with a file manager. Then unmount the Kindle and select the Update option from the Kindle menu. If the Kindle isn't automatically mounted, use a disk manager, e.g. Gnome Disks. (Even though it has Gnome in the name it doesn't require gnome.) – Nemo XXX Dec 25 '18 at 19:54
  • @NemoXXX thinking out loud, and didn't want to brick it. Thx. – Thufir Dec 28 '18 at 18:58

the K3 automounted fine:

thufir@dur:/media/thufir/Kindle$ 
thufir@dur:/media/thufir/Kindle$ cd
thufir@dur:~$ 

Then I unmounted the K3. But, there's no update option. Registration shows:

Voice Guide

Device Info

then menu, select settings, then menu again for the update option.

  • If the update option is grayed out, you either downloaded the wrong .bin file or the .bin file was corrupted. Re-download the .bin file and try again. If all else fails, ask for help in the Kindle Developer's Corner. – Nemo XXX Dec 28 '18 at 22:15
  • It took two tries. I had to press menu from within settings as I recall. In any event, thank you. – Thufir Dec 28 '18 at 22:20
