Got a bricked Q-See QC828 NVR, won't boot, tried everything. Support no help.

Poking around I came across the "TFTP Upgade Instructor" on the Dahua site:

http://www1.dahuasecurity.com/download/TFTP upgrade instructor.pdf

I found the latest .bin file but need the "armboot-x.bin.img" mentioned in the instructions. Is it a "generic" Linux file? Any idea where to find it?

Also, I see posts that mention the new .bin file has to be re-named to "upgrade.bin" and the armboot-x.bin.img to "u-boot.bin", anyone confirm this?

I have an old laptop with a serial port and cable, I think this is my last chance of un-bricking this thing.
