R8000 Boot Failed When JTAG is Connected
Well this is going to sound odd, but I am having some boot issues with my Netgear R8000 while I have an adaptor connected to its JTAG port, and by issues I mean all of it. When the ground pin on the Adaptor is connected, the power light displays white and It simply will not get past the light test part of the boot process. 
 
It is currently bricked (I assume so at this point, all pings return "Host Unreachable) after updating from one of the recent Kong builds to a direct dd-wrt version and adjusting the clock speed. It somehow glitched out and set the clock speed to 0, but during the boot process it ignores it and sets it back to 400mhz. I found this out by powering on the router with the ground of the JTAG adaptor disconnected and then plugging it in immediately after the light test phase of the boot. This gives a short burst of information before freezing, but this burst is inconsistent and sometimes contains something new, but never the whole thing.

What appears to be Fully Booted Lights and command line after connecting JTAG quickly after light test:(There should be a photo here)(There should be a photo here)
 
Example of Inconsistencies from "tricking" the router multiple times:(There should be a photo here)
 
I spent a whole week messing with this thing and I just can't figure out what is going on. Any help would be appreciated.
