I have removed the nand chip from the Now TV and took a full dump. I also bought a Roku 2 XD and will be taking a full nand dump of this too, I will then reflash the now tv nand. I went with the XD as it supports 1080p and the only hardware difference is a microsd slot and the bluetooth (which are unpopulated on the now tv board).
The lack of microsd wont be a problem - as there is nothing connected when the slot is empty anyway. Hopefully the lack of bluetooth wont stop the XD firmware booting. If it does, I will get a LT - but I figured 1080p support was a nice upgrade.
There seems to be references to ttybcm0 in uboot, which also gives serial connection settings. I have the pinout of the BCM2835 (same as the raspberry pi) with the possible pins for serial (depending on how its configured).
I will probably remove the CPU and trace out these 3 combinations and try to get serial access. Assuming uboot isnt locked down, should be easy to flash from there.

That wont work, the USB controller is missing. The higher end rokus have a chip that handles USB and Ethernet - the SMSC LAN9512-JZX. This is a "Hi-Speed USB 2.0 Hub and High-Performance 10/100 Ethernet Controller". Without that chip (and the missing supporting surface mount components) you wont get USB or ethernet, even if you do solder in the port.

That is a Roku 2 XS board, not a Roku LT. The LT board is the same as the Now TV board - i.e. a bunch of unpopulated parts.
