Well I got my Wrecker to update. Here's an explanation in case anyone else has the same problem.
I did it exactly as it's done in the video. The problem was that the video showed the mod's update port being turned on, THEN it was plugged in. When I did that the update software didn't detect the mod. Well apparently after a(fairly short) period of time being inactive with the update port turned on, the mod will automatically power off. When it did this it disconnected and reconnected to the PC, and the PC failed to install the drivers. So, I went into "devices and printers," found the port with the "unknown device" connected, and tried to get it to install the drivers. According to Windows the device didn't need any. Tried the update software again for the hell of it, still nothing. Tried different USB cables, nothing. Well, when I was trying to install the drivers after the initial attempt I didn't turn on the update port because I didn't want it to shut down halfway through again. The PC was still detecting a device, albeit an unknown device, so I didn't think that was a problem. Well it was. What ended up working was I turned on the update port and quickly went in and manually selected the drivers folder within the Hohmtech folder from the update software download, rather than letting Windows search for the correct drivers. That way it was installed before the mod shut itself down. Problem solved.
If anyone thinks they're having the same issue, PM me and I'll go into more detail.
