This is a quick tool I threw together in my free time the last two days to make changing avatars to custom ones easier for myself. It works by terminating the account service on your Switch which will lead to a crash. While I have had 0 problems testing it, it does write to system save data, which some might consider risky. Also, guaranteed ban online. You've been warned.

Avatars are 256x256 JPG files. Place them in the folder sdmc:/avatar/. Avatool will only see files with the extension '.jpg'
Once on the main selection screen:

• L and R change the targeted avatar image
• Up and Down control the file menu
• A will overwrite the target with the selected source image

If the write was successful, you will see the target image change. Reboot and it should show on the home menu and profile screens.

Keep in mind this isn't supposed to be anything fancy.

Attached is a hacky build for Avatool for FW 16.0.0 for testing.

Simply unzip the file below and place the .nro file in your /switch directory to try it out. :-)

Sadly, I’m told, this does not work. We will have to wait.

I wasn't aware people still used Avatool to be honest. You can actually pull it off using JKSV too, but it's a bit more complicated. I'm assuming it shouldn't take much to take JKSV's gfx.cpp file and get Avatool functioning again. Perhaps a weekend project?

Avatool was just a quick project to simplify the whole process. Same thing with biggestDump. They're just JKSV under the hood but targeting specific uses to simplify them. I had others too but they're long gone. RIP old laptop.

Actually, looking at it now, it's going to take a lot more work than I thought. Changing PlServiceType does get it up and running again, but I'm not really happy with the rest. I've also found an odd bug I don't remember. I'm thinking since it's such a small quick project, I might just rewrite and rework it some time.

Awesome! Appreciate your time looking into this. Obviously not mission critical but sure is a nice to have.
I have a freshly upgraded V2 and happy to Guinea pig for you if needed.

Hey I used this version on my file based atmosphere emunad, with 16.0.0 firmware and it works, (it does crash the console while doing it but my profile image was still changed, after restarting the console) I don't remember where I got it, because i did a full format of my old sxos emunand, and I downloaded so many things to bring back my console to live again, so I didn't keep track, but here it is, oh and i used this guide to make a working jpg file:

Thank you, I've been searching for a long time。
