Hardware 3DS stopped working for literally no reason?

[heliopause]

I turned on my CFW O3DS and got just a blackscreen. Literally five minutes earlier I had been playing Pokemon and my battery ran out, I took out the SD card to put on a new theme, put it in and got a random black screen.
No, this isn't me screwing up with my 3DS setting up CFW, I have had homebrew working on my 3DS for a while now and this is random. I let my 3DS sit for a while and it just sat at the black screen with no response.
Idk what's happening, pls help.

did you get your black screen when booting your device, or when you try to install your theme?

probably corrupted some data on the sd card because of removing the sd card.

maybe replacing the a9lh files fixes it

Do you still hear the system menu music?

Check the sd card hasn't somehow corrupted

I have a complete backup file of both my 3ds SD's, should I just replace the a9lh files or all of them?

 

[heliopause]

Nope, just a silent black screen.

Try using a different sd card for the time being to see if it makes a difference

I tried no SD card, a different SD card and had the same result.

Bump???

backup the sd card files you had, it really should be the sd card problem.

can you launch in other modes with the buttons pressed?

 

[heliopause]

Ah I booted up Luma and it got the same black screen so I replaced it was the files you suggested and nothing happened so I just replaced the ALL files with my old backups and it ran, I guess something corrupted??

yep, probably because the 3ds went "off" deu to battery low, it was still writing to the sd card, that moment you pulled out,and shitt happened (hehe pun intended). anyway good to see it is fixed
