Hacking Uninstall from older CFW?

[chillandserve]

I installed CFW on my N3DSXL a few years back. Things were going smoothly until I closed the system and opened it. The screens were both black and the power LED flashed blue for a second before turning back off. I had assumed for years it was bricked and put it in the closet. Recently I discovered my unit has an IPS screen and decided I would try to save it. Long story short I was missing a file in the root of my SD card called "arms9loaderhax.bin". I was able to find it and now my 3DS works again. Unfortunately, the laptop that had my old files was reset and given away and the SD Card I used with my system was formatted and has been moved to another system. Is there anyway to uninstall the CFW on my system at this point? The only things on my SD Card at this point are the default folders the system adds and the arms9loaderhax.bin file.

You should follow this guide first to upgrade to the more modern boot9strap: https://3ds.hacks.guide/a9lh-to-b9s
After this you can uninstall CFW using the guide from that same website, but there's really no reason to uninstall CFW unless you want to sell the 3DS as a stock unmodified system. Uninstall at your own risk, it's safer and better to keep the CFW on the 3DS.

If I update and keep the CFW is there a chance of getting bricked through an update?

If I updated and kept CFW could I get bricked with updates?

There is a chance that the CFW will temporarily stop working because of an update, like it has recently happened with the 11.14 update and bad code in the Luma3DS CFW. If it ever happens, you can get it working again by just putting the updated CFW files on your SD card.

Also, the newer CFW setup installs a boot.firm file to your NAND, which makes the console boot even without an SD card.

The tutorial mentions a /luma/payloads folder that I am missing. Do I just add it to the root of my SD card?

Just create that folder if you don't have it.

I think I’ll keep the CFW. Installed everything and don’t do the point of undoing it. Just have to backup the SysNAND with a bigger SD card. Probably get one tomorrow.I appreciate the help.

Well I got the SD card and copied some files over. I had to start the guide over because some files weren't copying over. For some reason I can't get the first part of the guide to work now, when it says boot to safe B9SInstaller my system boots directly to the home menu even though I followed the steps in the same way.
