I updated to 11.5 on my 2ds does this method work there too? Or what can I do?

Dylan Greene

After updating to the latest luma hourly, I pressed start to reset my system as instructed. But instead of restarting, my 3DS turned off completely. Now, every time I try to turn on my 3DS, the blue light comes on, then quickly fades way. The screens won't even turn on, so I can't boot into Luma chainloader I order to unbrick my console. What do I do???

Do I have to update the latest hourly of stable version in luma, because I can't update hourly


I have a question and idk where to ask, I can't seem to find any discord for 3ds modding to ask. My modded 3ds xl top screen broke and shows no picture but the bottom screen still works. I recently got a N3ds xl so I can system transfer BUT i'm not sure if it's safe to system transfer from modded 3ds to non modded N3ds. I wanna get cfw on my n3ds but can't find anything on getting cfw on ver 11.4.0-37u. I was hoping buying an used n3ds it wouldn't be updated but it is.


can you do it for the 11.6.0


Hi, I just finished doing this and I just have one question,
is it safe to update to 11.4 now? Like, if I did would anything happen to Homebrew and all that. Tbh the only reason I want to update to 11.4 is to stop the message coming up and having to use ctr-httpwn.

מזיד זיאדה

Sword of damocles

You missed the update step(in case of not being latest firmware)


Hey so Ik this doesn't have anything to do with boot9strap but I just recently ordered a transparent blue 2ds with the firmware 11.6.0-39u for basically retail price. Is there any way to homebrew it with that firmware? A video link would be appreciated, thank you!

William Ruvalcaba

I checked out the current guide and it's different is that relevant?

Manu Manu

Hello, I'm happy to see you again. I transform my 2DS with you. Now a friend give me a challenge transform a new 3DS XL 11.4 with no cfw.

Alysha Eyre

What are the benefits of boot9strap, i understand that i can't update luma anymore with A9LH but why should i wanna update Luma? What can you even do with Luma? I have my FBI so i can install everything i want.

Cent Teq

So i did all the steps and i got the new updater but when i up dated it said restart i said ok but when i tried turning my 3ds old xl back on it would shine blue but then turn off so some one please help :(


If I use freeshop on a9lh with spotpass turned off will it still work?


Nah Not doing anything until we get more news and details about the new banwave


@OPERATIONiDROID how would you switch hourglass9 to godmode9 from already cfw 3ds

Rowan Yates

I have completed the update and everything works fine, However the Homebrew Launcher Loader will not work. It is the latest version but just will not load up. Is this anything to do with the cfw update with Boot9strap? Or is the launcher itself outdated now?

Saad Khatri

Is there any way to download this hack withou PC cuz I don't have one.


So many nubs in the comments xD. Also its still luma cfw, so your title is wrong xD


i have cfw but i dont have a luma file


hi im doing the new luma updater thing and it says configuration file loaded successfully unknown or wrong config value: a9lh for 'payload type'

Trainer Specter

If you are not banned from wifi but still worried about getting banned,follow the following steps:
1.Go to system settings
2.go to internet settings
3.Click on spotpass
4.Click on 'Sending of System Information'
5.Select 'No'
6.Select 'OK'
(Your settings will be saved and you will be good to go from there)

RandomAsianKid XD

I need help when I hold the "Start button to launch the SafeB9SInstaller" it says "SigHaxed Firm was not installed"


I have an issue. While holding start while powering on my 3ds, only godmode9 shows up. I've deleted every single godmode9 file on my 3ds except for the new .firm file and it still boots into it. I can't update my 3ds to boot9strap due to godmode9 always taking it's place. I've tried renaming start_ to "insertbuttonhere_" on the bin file and it just boots into my 3ds normally. WHY WON'T IT WORK?


Ever since I updated to B9S I haven't been able to enter CHMM2. Amy idea why that's happening?

Manu Manu

You said in the beginning of this video : there's a way with a another 3ds. Which one has a cfw. if you could make a video to explain this made. It would be great.

Btw, when i deleted arm9loaderhax.bin, 3ds won't turn on. when i used my bak up file by removing .bak, 3ds works again. So.. i guess it's not safe to delete arm9loaderhax.bin or did i miss something out? Thank you for your ASAP response. XD

Amal Sanuja

Lillie Spears

You appear to have made an error. NTR CFW also works for old3DS. It's video streaming that's new3DS exclusive.
How about a video on GBA VC injection?
