I meant the answer to your question.
From the u-boot command line, enter:
bist fastboot
You will not get a battery voltage report (at least, you didn't in the past).
But if you do, then that is an improvement - -
It should allow you to avoid destroying your flash chip.
Since you naturally would not start any long running set of erase/re-program cycles with a battery that is reported as having too low a charge.

How do you know that fastboot isn't working?
Tell us all details of the fastboot and pc you are trying to talk to the Kindle with.
PS: You do know that there is more than one program named 'fastboot' don't you? and that you must use the one of that name which is specifically for the gray scale Kindles.

"Un-brick with a new firmware ..."
Meaning you brick the 'diag' mode of your Kindle and you want to un-brick that?
Because the 'main' mode image is too large for fastboot to handle, you can't un-brick the 'main' mode with fastboot.

This question and answer session would go a lot faster if you just gave us **all** of the details of the current situation and of what you are attempting to do.
Include details of all that you have done and the results of each.
