I tried to disallow RetroArch to show the little horizontal pop-up that appears when you start a game (That tells you what the game is and the core it’s running on). I disabled pop-up notifications and the other option that I thought I wanted to change, I also changed the color profile and size of the text for RetroArch.

At this point, it either froze immediately and I tried to reset it several times before it refused to turn on, or it operated fine before I shut it off, and that’s where the problems began. The Yellow charging light turns on, and my computer makes a noise when I plug it in via USB. When I put my ear to the device in total silence, I can hear a rough high-pitched whirring from the device–almost comparable to a hard-drive’s mechanical sound up 2 octaves.

If you have anything at all to contribute, please do. I created an account here solely for this issue.

Update 1: I unplugged the battery and plugged in the the USB-C charging, this caused it to boot. the screen was active on the boot-up screen, but after it finished the screen went black. the system was fully functional otherwise, I could hear the menu navigation sounds. From there its impossible to know where I am in the menu, and the sleep function works, but the resent button did nothing and neither did holding the power button (but I’m not entirely sure it did anything before).

You were probably stuck in FEL mode, no need to disassemble the device. There’s an explanation on how to get out of it here: [My device is not booting!](https://community.muos.dev/t/my-device-is-not-booting/35)

Now that you get it to boot, if you can hear the navigation sounds, just increase the brightness with menu+volUP

And don’t ever use the reset button when stuck in these situations, use the safe shutdown or safe restart hotkeys: [When should the reset button be used?](https://community.muos.dev/t/when-should-the-reset-button-be-used/44)
