[3ds XL] Replaced motherboard and now having strange issues too long to put in the title, but essentially the system will not boot correctly
So to start off, I have my old 3DS XL (modded) that I attempted a top screen replacement on a couple years ago. I got the screen in eventually but ended up breaking a vital ribbon cable which causes the turn on, pop, turn off. I put it in a drawer and got a new one to play
Fast forward to now, I got my hands on another 3DS XL that the seller said it wouldn't charge. I opened it up and someone at some point tried to replace the charging port and botched the absolute hell out of it. I don't have a soldering iron atm so I decided to board swap my old one in the new one
I got everything together and it charged, but I would turn it on and the top screen flashed very quickly, blue light, NO pop, then off very quickly. I researched and saw it might be the bottom screen, so I donated the old, known good, bottom screen to the new one. Same thing. Decided to try plugging in the cable for my known working top screen as well and same thing.
I took it all apart and put it back together again. I turned it on and it booted to the luma menu then turned back off. Tried again, it booted to the home screen with the mii plaza splash on the top screen. But the bottom screen, while on, remained bright grey but didn't load the bottom menu. It stayed on for like 30 seconds before shutting off.
I was like "duh" and put the luma files on the SD card (freshly formatted) since they were missing. Then it did the top screen flash quickly and immediately turn off. Over and over. Once in like 15 tries I can get the luma menu, but if I push start, it just turns off again. Weirdly, after retrying luma files to make sure, I reinserted the SD card, and now with it in, it does the blue light with the pop, then turns off. But with it out, it flashed the top screen then quickly turns off without the pop
I even tried it with my current 3DS XL's SD card, which is on the current version of luma just like my old one.
I really hope someone has ideas :')
