Homebrew Help! 3DS won't boot all of a sudden!

[KyoIsHacking]

My New 3DS all of a sudden won't boot from my SD with Luma3DS and b9s installed.
The screen just stays black and i hear no sound, not even the typical sound when the screens turn on.
I tried booting it without the SD and it works. But if i put it back in i cant even go to luma chainloader or it's config.
I also tested the SD with h2testw but it didn't find any errors. What should I do now, help?

You can try replacing the boot.firm with a new copy of boot.firm from 9.1 Luma3DS.

I tried that already...

It looks like somehow you lost CFW, if you can't get into Luma Configuration menu or the Chainloader menu.

I don't understand how that could happen... i did literally do nothing to the files on the SD

--------------------- MERGED ---------------------------

So what should i do now? try to update my b9s via the 3ds guide site?

Got another SD card to test with?

Aren't you on B9S 1.3?

Umm yes, I'm gonna try that.

Aren't you on B9S 1.3?

AFAIK, I am, I just thought, maybe some files got corrupted or something.

Holy god... it actually works with the other SD Card! but i don't understand whats wrong with the other one?

You can try backing up all the file off the other card, then format the card again see if that help.

 

[KyoIsHacking]

I'm gonna try that, if it doesn't work then I will just use the one which is working now. Thank you so much for helping!

SD cards are great (if real) but still dont last forever. Maybe yours has just reached its end?

Check if your card's fake with H2testw in a Full Write + Verify Test when it's empty.

Well I can still read/write on it from my laptop without problems and a test for errors didn't give me any..

Try booting with a different SD card with a test custom firmware setup. Look here for a quick build. If that doesn't work either, what model 3DS do you have?

You may be looking at a replacement SD reader.

Edit - If the temporary CFW with a new Nintendo 3DS folder works, try these on your main setup.

Umm I moved all my files to another SD Card and it works perfectly. Idk if it still has relevance but it's an New 3DS XL EUR.

Wow, I'm not on top of things today. Sorry, I didn't read or follow the previous posts.

Here's what you can try on your troublesome card.

Reformat the card with this first:

• SD Memory Card Formatter

Reformat it again with this:

• MiniTool Partition Wizard Free Edition
• MiniTool Partition Wizard Software Tutorial Guide
• Format settings:
  • Delete Partition
  • Initialize to MBR Disk -or- Convert GPT to MBR Disk (if it's in GPT Disk)
  • Rebuild MBR
  • Create a New Partition [ Create as: Primary | File System: FAT32 | Cluster Size: 32 KB ]

Check that card again with a test setup.

Edit - I would personally retire the card if it derped on you before. Take it as a good sign that it was warning you its time has come.

I'll try that on the weekend maybe. Thank you.

Files can get corrupted on an sd card without you doing anything. I'm guessing that's what happened here. Happened on my PSP recently.

Weird thing is after a format and reinstalling the files it's working fine again.

It's never a bad idea to keep all your files backed up on your PC in case something like this happens again. I even back up my saves.
