ROM Hack 3ds doesn't boot

[fir3dav3gam3r]

Hello my old 3ds doesnt boot with sd card just the blue light flashes for 1 sec. When i put the sd card out and start, it starts but there's just a blackscreen and no sound. I have CFW but can't go into any menu.

Use another clean SD card with FAT32 format (32kB cluster size, primary partition, MBR table) and put only the boot.firm and the boot.3dsx files from Luma latest on the root of that SD card.

If works, then continue with this entire guide:
https://3ds.hacks.guide/finalizing-setup.html

And with the actual SD card, better check if it has any problem (is corrupted/faulty/damaged), performing the quadruple reformat technique + H2TestW analysis (try to backup all its content before start with this).

Take off the SD card. Then turn on your console while pressing SELECT button.

• If Luma config menu is shown, please take a picture of both console screens and post here.
• If nothing different happens (black screens remains), try to boot your console but on Safe Mode (pressing the combo L+R+A+Up while power on). And also is recommended trying with battery trick.
• If the "brick" persist, then perharps you will have to use ntrboot + GodMode9 to unbrick it.

Also there's a slight possibility that the SD card reader/slot of your console itself was damaged or failing.

I've had that happen to me before... I can't post a link, but I did fix it.. It is something with your custom firmware. Did you just update it?
