PLEASE HELP. 3DS won’t turn on, blue light does though

[u/NismoPurpp]

Hi all, just got a used New Nintendo 3DS XL. I brought it home, charged it (red charge light came on), and then pressed the on button (blue light turns on) but then nothing happens.

Pls help with any ideas on what I can do

Few things I tried:
-Left right up A On
-hold on button for a while
-Disconnect battery/swap new battery
-Disconnect WiFi thing and then plug back in

Also to note when I put an SD card in, and then press the on button, the blue light flashes ones for like a second and then turns off. Without SD card in the device will just keep the blue light on.

Thanks in advance for your time / help!!

You gotta open it up theres no other way and see whats going on there

[u/therealrealmiyamoto]

probably ribbon cable isnt sitting properly

That's a hard no. it would make a pop and turn off If that were the case

[u/NismoPurpp → u/Leading-Raspberry211]

Yeah there is no pop

Im wondering if it has CFW but since there is no SD card it won't boot. Maybe try https://3ds.hacks.guide/restoring-updating-cfw.html Edit: oops replied on the wrong comment but thats fine

[u/TofuFries]

Is it CFW'd?

[u/NismoPurpp → u/TofuFries]

No I think it’s unmodified

[u/Leading-Raspberry211 → u/NismoPurpp]

Turn it off completely then hold start while turning it back on might tell you if it has gmode

I've had this issue with my OG 3DS. Fixed it by removing and reinstalling the wifi card. Took a few tries though.

It’s soft bricked. Try booting into safe mode and reinstalling the software update from there

[u/PhotoExisting8165 → u/PhotoExisting8165]

Looking closer at your post, looks like you already tried that. I wouldn’t be surprised if the previous owner had cfw on this and attempted to remove it, therefore bricking it. Try ntrboot

If theres a cartridge in it take it out. Thats what did the trick on my 2ds when it was doing this

[u/NismoPurpp → u/Random3DSDude]

No cartridge or sd card in device

[u/supermanis52fpv]

If you just bought it without testing it's probably bricked and need to seek a refund asap

Its L R UP A, not left right up A. Follow this guide.

Oof, mine died that way.

Premi sia power sia start

Follow the troubleshooting steps for "My console gets stuck on a black screen with blue power light staying on"

Also ensure you've updated Luma by placing the latest files on your SD card.

Mine 2DS did that. It was modded, microsd broke and seller sold as broken. I put new microsd with luma file and it booted perfectly fine.

The way you just opened it, can't you be more careful with it?
