Hacking New 3DS XL black screens

[froggestspirit]

I got this new 3dsxl on ebay, when i got it, it boots, you hear the system menu, but the screens are black. I installed b9s with a flashcart, and the screens work for that. I tried safe mode, and that worked. Ive tried to ctrtransfer, wipe the ctrnand, ctrtransfer again, etc, i cant get it to boot the home menu. (Godmode9 and other payloads still boot and display fine, along with safemode)

Edit: the camera ribbon cable was malfunctioning, and causing this

Do a CTR transfer with Decrypt9.

I tried this, although it still gives black screens with a blue led and yellow led for wifi. Booting without the SD card does the same thing

Try deleting the extdata. It's found in Nintendo 3DS\xxxx\xxxx\extdata\00000000\0000008f. For USA consoles, delete what's in bold and try booting.

Are you doing a 11.5 CTR transfer?

Yes, ive tried both that, and a ctr transfer i made from my working small new3ds.
Im kind of looking to completely wipe the system, i got backups of movable.sed, localfriendcodeseed_b, and secureinfo_a

Do you have Luma injected into CTRNAND? If so, with the power off, take out your SD card and then try booting the 3DS to see if you get the Home Menu to load.

If you don't have Luma injected into CTRNAND then follow this:

Section VI - CTRNAND Luma3DS

1. Launch GodMode9 by holding (Start) during boot
2. If you are prompted to create an essential files backup, press (A) to do so, then press (A) to continue once it has completed
3. If you are prompted to fix the RTC date&time, press (A) to do so, then set the date and time, then press (A) to continue
   • Note that, if you had to fix the RTC date and time, you will have to fix the time in the System Settings as well after this guide
4. Press (Home) to bring up the action menu
5. Select “Scripts…”
6. Select “setup_ctrnand_luma3ds”
7. When prompted, press (A) to proceed
8. Press (A) to unlock SysNAND (lvl1) writing, then input the key combo given
9. Press (A) to continue
10. Press (A) to relock write permissions

Yes, i have luma both on the sd, and injected into sysnand. Booting without the sd card gives the same symptoms as with it

Wow, well alright then. Let me dig a little more for things to try. Will post if I find something you haven't tried yet.

Do you mean a CTR transfer or NAND backup? A NAND backup won't work and there's no reason to extract a CTR transfer image from another console, since there are community images you can use.

Im wondering whats wrong with it then...
Edit: boots now with menu sounds, screens dont turn on, and freezes shortly after
Edit2: i got it booting correctly, i unplugged a few things from the mobo, ill try plugging them back in 1 by 1 to isolate it. It was a hardware issue
It was the camera ribbon cable
