Kindle bricked after flashing kernel
So here is what I did:
I followed this to make a backup of my kernel: http://www.christian-hoff.com/?p=16
Then I booted into diags and from there into fastboot. This is the last time I saw my screen change.
sudo fastboot download uImage-usbotg sudo fastboot flash kernel sudo fastboot boot
The screen stays blank, but I eventually find out bootmode is set to fastboot, so I set it to diags. I never touched diags, so I thought that would be the safest thing to do.
My screen came alive with that weird line drawing that shows when you boot diags, but it stayed there.
Extra weirdness: lsusb showed "lab126 Kindle 3" at on point. Other than that, it shows "lab126" or "freescale something" consistently.
The led at the bottom also doesn't turn green anymore.
Only thing I changed is the main kernel.
Only thing that makes the screen do *anything* is diags.
the screen just changed from the lines to the empty battery pictogram. It was full yesterday evening.
The config I used for imx_usb_loader reads
A tree with a loading bar just appeared on the screen. It is stuck halfway. I have absolutely no clue what's going on inside of this device. I wasn't doing anything.
It just flashed the screen and did it again. Load half the bar, get stuck.
Ok, I'm back in. There are definitely some strange issues with my setup, but my backup works. Sorry for the clutter.
Unless someone has some insights to share, this thread can probably be deleted.

What model is your kindle?
Do you have matching compatible kernels and partitions? Is your battery fully charged for 20 hours using a wall charger? If not, that could be your problem.
After your edit, it does look like your battery needs charging.
