Chromebook 3100 RMA Shim

My Chromebook 3100 stopped working a few weeks ago, due to what I can only identify as a general motherboard issue.

I decided that I would just order a new one, instead of trying to debug the issue, so I got one from a listing on eBay.

What I didn't realize at the time was that new motherboards require an RMA Shim to perform initial setup.

The board came yesterday, but I've been unable to use it due to the lack of the RMA Shim.

Despite scouring the internet, I can't seem to find the shim anywhere, so I'm going to ask here where I would go about finding one.

I unfortunately haven't been able to contact support about this as I'm broke and my device is out of warranty.
