There was an issue with u-boot failing to transfer correctly from phone to PC, 
usually when trying to back up the rootfs. I remember mention of a patch, but 
I can't confirm that it's now fixed as I've not tried it.

With the FR you don't need to worry too much as there is a failsafe u-boot in 
NOR in addition to the updateable one in NAND. The failsafe one can't be 
overwritten if you don't have a debug board, so you can always use it to 
flash a new bootloader to NAND.
