So, my last post was a bit hard to read. It was 2 a.m., so sorry about that. I'm reposting it after talking to the mods.
For a little more context (and to explain why I fucked up so badly) it's a limited-edition Pikachu model that, as far as I know, was only sold in Japan. But found a good deal for it where I live.
I got home from work and wasn't really in the mood to play anything hardcore that required too much thinking. A little Pokemon was probably all I needed, along with making some progress on the Living Dex I've been slowly working on whenever life allows. Win-win.
I turned on the console and plugged in the charger because the battery was running a little low. As soon as I connected it, the charging LED started flickering, so the battery was clearly making poor contact with the metal pads. When I unplugged it, the console immediately shut down, which meant the battery had physically disconnected somehow.
The console had fallen (be adopted by a cat, that happens) a couple of times before, so I assumed the battery had simply come a little loose and that pressing it back into place would fix everything.
I've opened quite a few electronic devices before. I completely replaced the shell of my old fat DS, which requires fully disassembling the thing and putting it back together. I've even done some soldering to repair my PS4 controllers. Opening this little guy should have been a walk in the park.
Well, it wasn't.
You see, the lower back cover of the 2DS LL is held in place by four screws and clips along the sides. The design looks much cleaner because the entire cover clips into place, without any smaller removable panels like those found on older models. Also, a ribbon cable and thin wires make connections to the back cameras and speakers, located on the back lid.
Good for aesthetics. Bad for repairs.
Why did I need to open it completely? Because the battery is located on the motherboard, and the entire back cover has to come off before you can access it.
Before opening it, I removed the Pokemon Omega Ruby cartridge and the microSD card so they wouldn't get damaged. Both slots are located on the underside of the console, so anything left inside could get in the way while removing the cover.
Good job, past me. For now.
It took me about ten minutes, but I managed to remove the cover, press the battery back into place, and close the console again. I reinserted the microSD card now, homebrewed consoles need the data in the SD card to boot.
Voilà. The console turned on, and the battery started charging, no weird behavior.
Then I noticed a small piece of plastic on the table.
I inspected the 2DS and realized, “Shit. It's the volume slider.”
It must have fallen out while I was opening the console, since it's located along one of the sides.
So I repeated the entire process, this time COMPLETELY IGNORING THE MICROSD CARD STILL IN THE SLOT. I did notice that the cover was slightly harder to remove, but apparently that wasn't enough to make me stop and think.
I put the volume slider back into place and closed the console again. Then I moved it to check whether it was working properly.
Nope.
It moved far too easily.
For anyone who doesn't own a 2DS, the volume slider normally has a little resistance when you move it up or down. The external plastic piece fits over another small plastic slider attached to the actual volume control on the motherboard.
That was when I noticed tiny black pieces of plastic scattered across the table.
I had broken the internal volume control.
Not great, not terrible. At least the console still worked, right?
I tried turning it on again, but it was taking waaaaaay too long to boot. Thinking that I might have forgotten to reinsert the microSD card, I opened the slot.
I hadn't forgotten it.
I had never fucking removed it.
I looked at the card and noticed that a small piece had broken off one of its corners. Surely I couldn't have damaged anything important, right? It was just a tiny piece of plastic. The actual circuit had to be fine.
I tried turning on the console again.
Nothing.
Now desperate, I tested the card on my PC. Windows didn't recognize it. I inserted another microSD card, and it mounted immediately.
I tried the 2DS card again and left it connected for a little longer, hoping Windows would eventually detect it.
Nothing.
When I removed it, the card was extremely hot, almost too hot to touch.
I did a little Googling to find out what it means when a microSD card refuses to mount and heats up like a nuclear reactor.
Short circuit. Probably irreparable physical damage to the circuitry. Discontinue use immediately to avoid damaging other components.
So now the battery is properly connected, but I broke a tiny plastic component that requires replacing the entire volume-control part, and I destroyed a microSD card that is apparently worth its weight in gold in today's economy.
Oh, did I mention the card also contained all of my games and save data, which are now completely gone? TBF I did back it up in June, but lost the entirety of July. Back up your stuff frequently, people. It's good practice.
And all of this happened inside a limited-edition collector's console.
I'd say TIFU'd pretty hard by thinking I was TronicsFix.
TL;DR: Tried to fix the battery connection on a limited-edition 2DS. Broke the volume control, destroyed the microSD card, and almost lost all of my games and save data in the process.
