Another HD Pro X Boot Loop...

[proffett]

I've seen a few instances of these things going into an endless boot loop, and powering up while pressing the left arrow key seems to be the common recommended fix. That isn't working for mine, unfortunately. Is there any other way to reset this thing? A reset button or jumper on a circuit board, maybe? I'm pretty sure the problem is a corrupted patch, because I loaded a few new ones on right before this started. 
Unfortunately it happened as the countdown was ending right before my Easter set at church started. Fortunately the keyboard player saw what had happened and was able to cover most of my lead lines as I went through the motions.

Anyways, I'm trying to reset this thing but nothing I'm reading on the great and mighty Google seems to be having any effect. I'm not sure I want to spend a whole lot of money tying to repair this thing since there's so little support for it these days. Might be the Good Lord telling me it's time to get a Helix...
If anyone has successfully rescued their rig from this loop by any means other than the ones that don't seem to work for me, I'd love to hear about it....

By "powering up while pressing the left arrow key" you have done basically a "Global Parameters Reset" but unfortunately in this case it didn't work to solve your boot loop issue.
At this point I would suggest to power up while pressing instead the down arrow key for direct access to Flash Memory update mode and then update the firmware through Monkey (at this time possible only in offline mode if you have downloaded the firmware file) or Line6 Central, which procedure would cause a Full Reset of the device.
