pab, you probbly did the same thing i did, your going to need to use k3flasher to dump your devid, flash hawhil's partitiontable then kernel then rootfs then reflash your devid, (the guide should mention to use k3flasher over atk as you should even bricked dump your devid!)
sadly k3flasher's only for linux, but a lil easier to use than atk.
i must stress out as it got me in the pickle i am in. dump your devid first before flashing anything to 0x0 but it sounds like your kindle cant start due to a screwed up partition table (even as is, with k3flasher run the backup script, then

but you mention the battery is dead now. charge for atleast 1 to 2 full days, and like knc1 had to stress to me Ignore the charge led. then try again.
