How do I downgrade a Homebrewed 3DS from 11.14 to 11.13?
My 3DS is set up for homebrew. I saw there was a new software update, and (foolishly) decided to install it. When it came time to restart the system, it gave an error stating:
An exception occurred
Processor: Arm11 (core 1)
Exception type: undefined instruction
current process : pm(000000000000000000)
crash dump (hex) is:

I shut down the system, and turned it back on. Same error. I also tried booting it into safe mode with no luck (Same error).
What can I do to fix this?

Eris the guest has it right, but for idiots like me, here's a step-by-step (assuming you followed the 3ds hacks guide):
- Download the latest Luma3ds files onto whatever you use to read/write your SD card (https://github.com/LumaTeam/Luma3DS/releases/tag/v10.2.1)
- Unzip the files and place the contents of the zip folder (NOT the folder itself) into the root of the SD card.
- Put the SD card back into the 3Ds, then boot the chainloader by pressing the power button while holding START.
- Press HOME, select "Scripts", select "GM9Megascript", select "Scripts from Plailect’s Guide", select "Setup Luma3DS to CTRNAND". Unlock the SD card to do so.
- Press "B", then select "Cleanup" the SD card.
- (May not be necessary) Press "B", select "SysNAND Backup", wait for it to finish, then press HOME and select "Power off" to exit Godmode9 and finish the fix.

Should I update my homebrewed 3DS?
Yes it's perfectly safe to update.What happens if I brick my 3DS?
At the most, it'll freeze and you'll have to hold the power button to turn it off. No. Just like with HBL, you can't brick your 3DS by running Homebrew games/apps (with the exception of downgrading) unless you're really trying to. It might freeze or refuse to boot, but there's no way to actually brick your console.What is a homebrewed 3DS?
What is homebrew ? Homebrew is what we call unofficial software made by amateur developers for closed systems such as the 3DS. This includes both games and applications, and in practice getting homebrew on your 3DS means you'll be able to : Play Aperture Science 3D, a free adaptation of Portal for the 3DS.Does 3DS Homebrew still work?
You can still play all your games, connect to the eShop to download new titles, and play online with others. It's apparently even safe to install an official firmware update with it installed, though again, it's unlikely any more of those are coming down the pike.[11.13-11.4]Nintendo 3DS Downgrading Guide (English)

Answer 2
I had the same exact issue with the same error for the same reason, last night.
I went to https://github.com/LumaTeam/Luma3DS/releases/tag/v10.2.1 and downloaded the zip file and replaced the boot files on my 3DS sd card (inserted into computer) with the two boot files from the unzipped file. As a precaution I copied all the data from the SD card including the original boot files to my computer before I replaced them.
I then safely ejected the SD card, put it back in the console and followed the Prompt to boot into the main screen (I think I pressed start or A, but it’ll tell you which one) and it started right up like nothing ever happened. The only thing that’s different is I don’t see the Luma splash screen anymore but everything else including godmode works fine
