Through my own stupidity (connecting more than one board at a time to the computer) I have clobbered the flash loader on my older Mojo v3 dev board, along with the default examples added to that original flash.
Maybe my search skills are lacking, but I cannot find either the original flash file, or instructions on how to flash a board that is not responding to USB. I am guessing I am going to have to add pins to the JTag and connect and refresh that way?
Any help would be greatly appreciated.

There are so many pages and files I am nit sure of what I am doing anymore.
Can I use the USB port to program the loader, or do I have to have some kind of "programmer" (which I do not own) and solder to the pins on the bottom of the board t be successful? I have tried a number of things in the tangle of pages here and the documentation is not always clear. For example, a number of times you say to extract the zip files into a folder you ask us to create, only to have the ZIP file expand just one folder with the files in there inside the folder you said to create. Am I supposed to just leave that folder in the folder I created, or move all the files in the ZIP folder into the new folder I created? It seems to be the second, but I have no way of knowing for sure if that may be a fail point.
Frustrating trying to understand the multiple threads of working with this board, and trying to get it re-working again. Seriously, the docs have me jumping between 5 to 7 pages. And of course, they really do not know about the content that took me to a specific page or from a specific page, so sone things may not apply.
In any case, all roads seem to point to soldering a programmer to the bottom of the Mojo board. I have no such device, and right now, I am not willing to purchase anything else. Seems like a waste because I have zero confidence this will work. This worked once, now it seems dead. Most likely I will simply toss this board and its shields into the recycle and move on if I cannot restore it.
Thanks anyway...
Thank you. Yes, that is the board I have. I tired the reset without success. The Windows machine does not even recognize the USB device.
I really have not done much with it but lay with the clock shield and do some FPGA experimenting. It was left connected to my machine while I was programming some Arduinos. On one program I noted they Arduino did not take the program. That is when I noticed that my Clock Shied was out. When I tried to connect to the board again it failed to respond.
I guess it is possible that something failed.
Appreciate the help. Sorry for the frustration.
