In this process I erased MMC0 by mistake and naturally ended up with a hard bricked kindle.
In the shining light of this I figured out how to successfully unbrick and downgrade my firmware, and now have a functioning Kindle again at FW 5.8.2.
Now my issue is that I cannot get in to diags, it seems that even though I've successfully flashed the firmware, I think I am missing the DIAGs partition.
Trying to bootm 0xE4100 doesn,t work, giving an error that uboot can't get kernal image, and chucking the ENABLE_DIAGS on the root of the /mnt/us directory and rebooting just boots normally.
I have tried flashing multiple firmware versions, as well as flashing an older firmware, then updating to a newer one, and while they all work, none of them seem to re-write the diag partition.
I'm kind of stuck here, a nod in the right direction would be apreciated
