Hacking Bricked 2DS System with no NAND backup, what should I do?

[Aidn]

So, long story short, I was installing Persona Q2 on my hacked 2DS via FBI, the install failed but my SD card kept the gamefiles, apparently, and I had no space, so let's say my dumb mindset was "Welp, let's delete stuff" And then it got bricked, I guess I deleted some important files even though I was on the SD menu and I had forgotten to do a NAND back up, so... What can I do? (When I boot it up without my SD card, it doesnt turn on, the power on light just turns off)

Also, I've tried using the usual L+R+UP+A to get to the restore menu, but it doesn't seem to work, also, I don't know how the GodMode9 Menu can help me.

When I turn on my 2DS it gives me a Crash message saying

If this is an o2DS, try resetting the RAM with the battery trick.

Have you tried downloading the latest Luma file and extracting the boot.firm file to the SD card?

Make a "CTRNAND Transfer" using the firmware files for any firmware with Decrypt9

@aiden should try less drastic troubleshooting before jumping ahead with the heavy duty stuff.

I advise against usage of Decrypt9(WIP)'s CTRTransfer. If it comes down to the point where standard CTRTransfer doesn't resolve the brick, he can instead try CTRTransfer (Type D9).

The problem might be that the file boot.firm from Luma 3DS is missing. Do what Harsky said. Download it from here: https://github.com/AuroraWright/Luma3DS/releases

Then place the boot.firm file into the root of your SD Card.

I did that, but the 2DS now stays in a black screen, no crash dump or anything
