Well, the debrick utility simply takes a bunch of bits (like an image
file) and sticks them in some location in flash. So if you have a
valid bootloader image, it can put it in there...
But the problem is that the debricker was written for Broadcomm chips,
not the TS-7xx0. So it would take someone with good knowledge of the
hardware, and of the organization of the TS7xx0 flash, to make it work.
Once it is set up, it's easy to use (I know, I've had to use it a
bunch of times).... :-)
