So I picked up this Wii, and it appears to be softbricked. Original SD card is not included but I suspect it was a bad mod or something. The GPU DOES output, but the only thing it produces on screen is a black screen with a single white dot in the top right corner of the screen.

I am unable to boot into recovery mode via spamming buttons/DPad on the GC controller.

Any suggestions on how to fix/unbrick this?
