No, probably the best thing you can do at this point if you don't know what you are doing is just create a new emunand altogether and reinstall all your stuff and don't try to downgrade in the furture.

If that's not something you want to do you should backup your broken emunand before you start messing about with it, then learn to use that program I linked as this is pretty much your last option to fix your current emunand. On the bright side at least it was your emunand you broke and not your sysnand.

Here's a short basic guide;

1: Use NxNandManager to dump your broken nand user partition (right click - decrypt and dump to file)
2: Next, use an old emunand backup which is working, update old emunand backup to 19.0.1 - test it works.
3: Replace user partition in your newly updated emunand with the decrypted one you backed up. (right click - restore from file)
4: Click save as raw dump - then replace the created file with the new emunand you made.

Try to see if this works.

I might have accidentaly deleted my emunand backup...
 
Access the atmosphere folder, then the patches folder, delete the exefs_patches bth patch and replace them with the folders from the Amelia patch. I tested it twice and the error was resolved.

Where do I find the Amelia patch folders?
And by "bth", do you mean bluetooth?

The only folders to be deleted are those in this path: SD CARD > Atmosphere > exefs_patches >. (You may have deleted specific Atmosphere folders.)

I did exactly what you said, exactly like you said. I am still getting the error.

So yesterday, I accidentaly downgraded my CFW to 19.0.1, and now every time I try to boot it gives me this error, with program 0100000000000025.
I was wondering how to safely update my emunand through maintenance mode, since there's no 0100000000000025 file in my atmosphere folder and fixing archive bit through hekate did nothing. I'm currently on HATS 718ca6c and hekate 6.5.2. And btw SysMMC CFW just gives me a black screen.

Any help would be appreciated. Thank you in advance.

If you downgrade from Firmware 20.x.x you user partition get damaged, Firmware 20 introduced a new User partition format so downgrading the firmware, the new firmware can not read it.

The only way to downgrade from Firmware 20 is to restore the NAND.

Also when you upgrade/downgrade your firmware you need to remove all sysmodules and themes to avoid this type of problems.

Is there a backup online? I kinda lost mine.
 
So... If I dump my User partition, or the one that contains all my game and save data anyways (probably USER), and then restore it on a new, up-to-date Emunand, or a factory reseted one, do I get my games back and not lose anything this way?

no, your current user partition if is not damaged can be only read by a nand on firmware 20+ but must be firmware of your console.
