Here's how to restore your KF to stock from a custom ROM
make sure you have the stock recovery installed (if you are in CM7 you are)
First, download the latest official update from here -> http://www.amazon.com/gp/help/customer/display.html?nodeId=200790620
then download this file -> http://www.mediafire.com/?31sljwzyu0i1nev
and place it on your sdcard
it should be /sdcard/command
rename the amazon update to update.zip (even if it's a .bin file, make sure it is update.zip, NOT update.zip.bin
then, place that file on the sdcard under /sdcard/kindleupdates/
it should be /sdcard/kindleupdates/update.zip
turn off usb mass storage mode
go into the adb shell and type
cd cache
mkdir recovery
cp /sdcard/command /cache/recovery/
idme bootmode 0x5001
reboot
i just went from cm7 to stock and it worked fine
