MM+ Doesn't Boot Up

Hope all you awesome people are doing well today! I'm new to the Emu scene and I'm running into an issue.

I got a good deal on this device that came pre-loaded with OnionOS and a ton of games (I know, ultra newb). It's been great the last two days, but it no longer boots up. I did something really stupid and I know it's the cause of the boot up issue, I just don't know how to fix it.

I got a second MM+ (purple) that came in today and like a dumbass, I figured if everything is already pre-loaded on the card, why TF would it not work?? So yeah, pulled the card out of the current device and put it into the new MM+ that was straight out of the box aaaaand bee boop. The grey one in the video is the original one that won't turn on anymore with the original SD card.

Any suggestions would be super helpful. TIA!
