Hard Brick on R7800

Not quite sure how, but I seem to have bricked my R7800, fairly hard. I have no response or traffic from the serial connection, and there is no ping of response to tftp. Im trying to setup JTAG to see if anything is even running, and possibly kick the router to boot. Worst case, need JTAG to write new bootloader. Not very experienced with JTAG, only done it a couple times, so looking for info on the JTAG port and pinout on the R7800, a fresh bootloader file would be awesome too. Thanks.

if this fails, something you will need to contact NG support about.
