If you need a Kernel, then you need both the Kernel and its matching build of modules.

You don't mention which version, so just get the update*.bin file from the Amazon support page.
Then take it apart with KindleTool from NiLuJe's snapshots thread.

I have been advised that the current update packages __do__ ship the kernel along with the main filesystem (they didn't use to).

You'll get the main kernel that way, yep. For diags, you'll have to resort to your own backups .

Wrong kernel build.
Hint: look at the build date (2013), the PW-3 wasn't even manufactured back then.
The initial factory install for the PW-3 is dated 20150630 and PW-3, 5.6.5 is even newer.

The series 5.6.x firmware kernels **are not general**.
Newer devices use a newer version of eMMC chip, which the older kernels can not use.

Use the 5.6.5 kernel and filesystem image posted by amazon for the PW-3.
http://www.amazon.com/gp/help/custom...deId=201756220
Use the most recent KindleTool build to take the update package apart to get at the files you need.
https://www.mobileread.com/forums/sho...d.php?t=225030

You **do** need to flash the main filesystem image also, not just the (correct) kernel.
Note: the main filesystem image is too large for fastboot to install.
You need a working diags system installed first and use that to install the main system's filesystem.

You will also need to flash a copy of the diags filesystem (not just the diags kernel).
I don't know where you will get that, it isn't (yet) posted on any of our recovery image sites.

Note: As a general rule, we do not post any recovery images on the image backup sites that Amazon is still distributing, but Amazon never distributed a diags system image.
(That is present in the flash when the board is assembled.)

Perhaps you can find someone in your own country that has a serial port installed on their PW-3 and who has not pressed the 'erase all' selection.
Have them make you an image of the diags filesystem and diags kernel.
The geekmaster scripts should still work for making the backup image of the diags kernel.
https://www.mobileread.com/forums/sho...=backup+script
The diags system image is the entire contents of /dev/mmcblk0p2.

Additional (old) information here:
https://www.mobileread.com/forums/sho...d.php?t=170929

= = = =

PS: the 'erase all' command selection does work, it has since way back when it first appeared, there is no need to try it out.
