Thank you! It took more effort than expected, but it did work, and I'm happy to finally have my Kindle back the way it was when it came out of the box.

I'm listing my steps here in hopes it can help others who want to take their Kindle Touch back to stock. I'm sure there are steps that can be combined or rearranged to make it more simple, but ultimately this worked for me.

1. Modify Kubrick ISO to add kt_5.0.0-kernel.img and kt_5.0.0-mmcblk0p1-main.img to /kubrick

This is the same directory as the fastboot command

2. Burn ISO to CD/DVD
3. Boot Kubrick
4. Follow on-screen prompts until the Kindle is configured for FastBoot.

The main screen will say: "Putting device into Fastboot Mode", "Press NEXT once your Kindle is in Fastboot mode", and the mid-screen indicator will be a green bar that says "Device ready".

5. Press ALT-F4 to open a command prompt
6. Login root, no password
7. cd /media/cdrom/kubrick
8. Use fastboot to re-flash the main kernel

./fastboot flash kernel kernel-5.0.0.img

9. Set the boot mode to diags (why?)

./fastboot setvar bootmode diags
./fastboot reboot

10. Boot into diagnostic screen

1. N) U) Z) X) on Kindle screen
2. Wait 20 seconds for dropbear to startup.

11. Copy main image file to the Kindle

1. ifconfig usb0 192.168.15.201
2. ssh root@192.168.15.244
3. Password mario
4. Alt-F3 to open another command prompt
5. Login root for Kubrick, no password
6. cd /media/cdrom/kubrick
7. scp kt_5.0.0-mmcblk0p1-main.img root@192.168.15.244:/mnt/us
Takes about three minutes

12. Reimage main partition

1. Alt-F4 to switch back to Kindle SSH prompt
2. dd if=/mnt/us/kt-50.0-mmcblk0p1-main.img of=/dev/mmcblk0p1 bs=4k
Takes about three minutes

13. In Kubrik, <Cancel>, and then continue Kubrick wizard from beginning to get Kindle back into fastboot mode

1. Do reboot kindle by holding down the power/home buttons as instructed
2. Screen will be back at step 4 about, "Putting device into fastboot mode"

14. Set the boot mode to main and re-boot

1. Alt-F3 for Kubrick command prompt
2. ./fastboot setvar bootmode main
3. ./fastboot reboot

Thanks again to knc1, ixtab, and others who made this possible.
