Deleted some red files trough FBI on my new 3DS XL and now its noot booting

[3dshacknoob]

Hey,

I'm a 3DS noob, who bought a modded System like a week ago. It ran smoothly with no issues, I was really happy about it and then I started to play around in the files...
in FBI I opened the "File" directory and saw many red files. I assumed these were leftovers from deleted games, so I began deleting them . After a few files I got an errormessage and now the system isn't booting. When I try to start it the light stays blue.
After some thought I booted it without the SD card and got this screen:

After some onlineresearch I found nothing and pressed "Save and exit". Well... the system isn't booting again. I'm a noob who just bought a 3DS and had no experience before. Did I delete "System32"? Any help is highly appreciated.

Red titles in FBI are system titles, so you deleted parts of the operating system. If you have a NAND backup you should restore it now. Otherwise you need to use ctrtransfer: https://3ds.hacks.guide/ctrtransfer

That was not "File", that was "Titles", which contains your installed titles.
Restore a NAND backup, or if you don't have one, perform a ctrtransfer by following https://3ds.hacks.guide/ctrtransfer
If you can't download the ctrtransfer images on that page (apparently there was some trouble with them) you can also find images on archive.org *snip*

Unfortunately I have no backup. I will perform the ctrtransfer! I do not care about any files / saves or whatever on this system, it's new for me and right now I want it live again.
Thank you very much for your fast responses, will update here later.

Edit: yes it was "Titles"

Instead of a CTRTransfer, you might be able to just use Recovery Mode as in https://www.3dbrew.org/wiki/Recovery_Mode . (This will not remove CFW.)

Never delete things you don't recognize.

This is not the first time somebody deleted system titles with FBI. There isn't much safety mechanism in this regard.

Pretty much just the red color as a warning using our instincts. Red → Danger!

Unfortunately I have no backup.

How can this happen? The guide tells you to create a backup (and in case of selling a modded system the backup should be already on SD – a sign why you should have done the modding yourself instead of relying on somebody else).

In any case try recovery mode first instead of the more invasive CTRTransfer.

If you have any further problems or questions, just ask here before doing anything you don't understand. Chances are you will get a nice reply pretty soon.

Good luck and have fun!

I'm really sorry to say this, I know it makes no sense, but you should not link to those images. Yes, your post is very helpful… still sharing Nintendo binaries.
*Sigh*
Copyright laws are stupid at times.

Fixed! Ctrtransfer was easy and fast to execute

Is it just me, or is it common sense to NOT go poking around in the file system of something and deleting things almost at complete random just for more space?

Personally, I think FBI ought to make it more clear that deleting certain things is a bad idea rather than just labeling titles with question marks and hoping people will figure it out. But eh, I'm not a developer.

I mean you are not expected to be going into FBI and deleting things unless you know what you are doing.

And even then, if you're gonna poke and prod around at system shit, why do it in FBI? And not GM9?
