What are all of the brick prevention methods?

[grabbingacat]

There are times when I'm paranoid and bricking a region changed 3ds might be possible, so what are all of the brick protections out there?
Note: Yes, I do have a nand backup , and no my 3ds isn't bricked (yet)

Don't uninstall CFW

Don't dick around with modifying system files unless you know what you are doing.

I dont know how to do that anyways so I should be fine. What other methods are there that can help me recover from a (potential) brick

Backup your NAND just in case. I also backup my SD card ~monthly in an encrypted archive file on my hard-drive and personal cloud. Better be safe than sorry, already happened to my Wii disk.
