Today I ran into issue #1 listed in the Mobian Wiki, where the boot process stops at a black screen.

Holding in the power button resulted in the phone rebooting rather than powering off, where the cycle repeated. It took several tries to get Mobian booted up. Tried the reset button in the back and finally had to remove the battery even though that's not recommended. This was a real pain, so for now I'd like to go back to uboot which never seemed to have any problems.
Before installing tow-boot I took an image backup of the eMMC using jumpdrive. Obviously the entire image could be copied back to the eMMC, but would it be possible to just extract uboot from there and write it to the eMMC using dd? What is the offset and length of the uboot image?
