3DS Black Screen When Booting Up/ Has CFW

I thought I had this problem, just turns out it took my system like...2 minutes to boot to home screen

For me this fixed it:

-hold power for 10s until the 3ds turns off

-remove game cartridge (in my case the ace3ds+)

-turn the sound up and press power. If home menu music starts playing and the screen is still black, just close the 3ds and open it back up

None of these worked for me.

If you are still having problems, try in removing the board from system. Attach the board to the battery via the bottom case and try to turn it back on. If the blue flashes and turns off, then you know the board is working and the issue may be one of the ribbon cables or the LCD. If the blue light stays on, then issue with the board

After following advice of resetting home screen settings (down/B/L/R on boot), my ds is now just stuck on the 'Opening homescreen' loading bar, and has been for the last hour.

Time to bin it? Getting real fed up with these 'fixes'

i really dont know what to do. same thing is happening with my 3ds. blue appears and fades. This was an old 3ds. Any suggestions on what to do?

I have a fix. You need to put the boot.firm on the root of your SD card. This should most likely fix the problem. You can download the boot.firm somewhere off the internet.

I'v had the same problem.

I was still getting errors by luma after complete installation.

SO i figured uninstall CFW cause it might causing any problems.

I was on ver. 11.6.0 now i was able to access settings (cause most of the time i get freezes)

game card isnt even working properly also i get error, while when cfw was on it it worked.

I did also a complete system format.

Somehow im stuck on 11.6.0 and my 3ds will not boot automatic configuration screen. (just light up black screens) Sometimes im able to boot trough save recovery mode. last time i did this i was unable to update.. now i'v readen something about primary and secondary dns.. i will try this.. anybody else formiliar with this or can help?

Thanks!

my 3DS isnt a CFW one but it does have this problem..and none of the fixes are helping...sugestion?

Try using GodMode9 and performing a CTRTransfer. Worked for me.

Try using godmode9 for a CTRTransfer.

If this doesn't work, Unfortunately you may just have bricked your 3ds.

These things can happen, even if the custom firmware is installed by a professional. Same thing happened to my brother and his was bricked. He just lost everything on there eventually and had to buy a new one.

Same Problem here and I’m running on the old model so I guess my one is bricked but what I tried was to use the reboot and if that doesn’t work try giving it to a person that knows how to program circuit boards.

Programming the circuit boards isn’t the problem — It’s either the SD CARD, or you 3DS Internal Memory(System Memory.)

Also, you 3DS has CFW…

One of the problems occurring with CFW, could be if you installed the dsiware-hack “Haaaaaaxxxxx”. My 3DS bricked(3 of them) before my 4th worked, so…

Oh, right: Have you been using R4, or TWLOADER/TWILIGHT-MENU? That could be the problem. My 3DS wouldn’t boot the whole time they were on there, so I used GODMODE9(or a different program) to programmatically delete them. After that, I practically let my 3DS DIE(Battery-Drain), and then re-charged it. After it was at 100%, I pressed the POWER BUTTON, and it booted up just fine.

Glad I could help,

The other cause of blue light is a non-functional top lcd, non functional bottom lcd, or camera ribbon. Try disconnecting the lcd ribbon and see if the system boots up. If the motheboard can stay power on without any ribbon connected, then there is an issue motherboard (hardware) or with software preventing to boot properly.

Well here one that fix my 3ds just leave it on in tell it runs out of charge!

Mine has a black screen, and the blue light will come on for like .75 seconds then turn off. None of these have worked. I swear, when I get mine back on, I’m never doing this again.

I had kind of a same problem, I have the old 3ds XL console with luma and it was working perfectly until one night that it ask me for a update of the console.. I didn't do the update for a week until I choose to and exactly when I press yes the console said to restart like not downloading time and after it never turn on again, always the blue light and the black screen

Anyone know how to fix it?

Hey guys, just came by with another solution that worked on my case :)

My 3DS XL (old model) has CFW and got the black screens and blue lights kept on.

Solution:

. Remove the batery and insert again;

. Power on holding only the L button;

Turned on like a charm

Alright I just had this problem with my 3ds new xl, I've been letting it sit after playing around with it for a bit seeing what I could do, noticed it took unusually long to hard off when i held the power button. Today I turned it on and noticed the red blinking light, it to was blinking slowly.

So after looking threw these I chose the simplest one, and huh. I just left it on for like 5-10 minutes while having a smoke.

I seem to have caused some sorta error in the bootup that just caused it to boot really slowly, I imagine an older model woulda been even longer. It seems to have worked through whatever error that was filling the cpu now that its got to the homescreen.

I also know it happened right after it was charging and we flicked a bunch of breakers on and off a few times, we were checking wiring. Oh and my sd is 256 gigs I could see that causing the occasional problem on boot.

Alot of these other solutions like taking out your battery, performing different kinds of resets for clearing you're caches. I'm sure taking out my battery or letting the battery run dry today woulda fixed it too.

well using recovery mode is not an option for me as one of my shoulder buttons is broken also my sd card is now on my phone as extra storage with nothing left of my 3ds data can boost mobile fix it or do i need a new one i do know that boost mobile can fix devices but im not sure of my new 2dsxl
