If you type "fastboot" with no parameters, it displays usage information, including the flash partition names:

Now you need flash to the main (primary) kernel with a main kernel image, and the diags kernel with a diags kernel image.

Depending on what filenames you are using, you fastboot commands should look something like this:

fastboot flash kernel main_kernel_5.0.0.img
fastboot flash diags_kernel diag_kernel_5.0.0.img

You can also flash the diags partition with fastboot, but the main partition is too large, so you need to flash it with the "dd" command in a diags SSH command shell.

When using a guide, it is important that you follow the instructions in that guide. Those instructions were provided for a good reason, and setting off in your own direction contrary to those instructions can cause additional problems for you. I suggest that you follow the instructions in the guide more closely next time.
Hi I followed the noon's guide to the letter but there were no fastboot instruction there to ask us to flash the diag_kernel as well.

This is the missing piece for those who are using the 5.1.2 main + kernel and corresponding 5.0.0 diag

My kindle is revitalised ! battery drain seems ok for the past 24 hours.

so thank you geekmaster and kcn1 for your help!
