I tried to analyze "onboot" but there seems not to be any key to press to switch.
I wonder: who loads onboot or u-boot ? Where is it? Analyzing THAT should give us the key to press to switch.
i think onboot is the first stage loader but question is does it looks at bml0/2 for uboot or it just (bml0/5?) loads the kernel (and if it loads u-boot what security checks are done).

Not likely. It seems they ditched uboot completely with C-Series: http://forum.samygo.tv/viewtopic.php?f=10&t=998.
However, there are secondary kernel/rootfs partitions in C/D Series (?); it should be somehow possible to select 1st or 2nd one on boot time.

in HOW_TO_INSTALL.txt there's only written how to create a squashfs image.
There is no mention on how to install it on the TV :)
I then wrote another email... don't worry.. I'm very resilent... they WILL COMPLY (in star trek's borg voice) :)
Good luck with that :). I'm afraid GPL/LGPL v2 is simply not precise enough on "installation" topic :(

EditIt seems that fnw.bin loads u-boot OR onboot.bin, but on 46D7000 also bml/4 is empty
i think fnw is handle bbm rescue system for flashing partitions and not to boot them.
(if its similar to b-series)

and also on b-series latest firmware (exeDSP) deletes u-boot and tv works normal. so maybe if an uboot is on the partition it will be executed elsewhere some other boot mechanism will handle the start seqence .
