Manta M8P/CB1 not booting

I recently received my Manta board with the CB1 module and I am unable to get the board to function. I have tried the following things:

- Downloaded your custom image from https://github.com/bigtreetech/CB1/releases/tag/V1.1.0
- Wrote that image to the 32mb SanDisk SD card
- Configured wifi setting to my WIFI
- Tried with Ethernet but the Ethernet connection never became active. At no time to I have lights on the Ethernet jack
- Tried several SanDisk SD cards from 8gb to 64gb
- Powering the board with 12v
- Powering the board with USB-C and V-USB jumpered. (12v supply disconnected)

At no time did the CB1 board seem to boot, and that's after waiting 10 minutes of waiting, also no IP address is being issued by my DHCP server.

I did notice that the 4 USB-C connector shield solder points were not soldered and the USB-C connector is loose but I don't intend on using that if I can avoid it.

I do get a red light on the Manta board next to the reset buttons, and a green LED2 on the CB1 board, but no other indication of functionality.

I feel like I'm missing something stupid but nothing I can see that's obvious. I tried sending this to the btt support email but it bitched about "Mail content denied" so I figured I'd try here.

Start with the CB1 V1.1.0 release image and compare its boot requirements with the reported SD-card, 12V, USB-C, Wi-Fi, Ethernet, DHCP, and LED observations. Reproduce the failure using the listed power and storage setups, then document whether the CB1 boots and which condition prevents network connectivity.
