nxdumptool VS aio-switch-updater

If you have a modded switch, you can dump it yourself using nxdumptool

I would use NX Dump Tool to dump games. It's been a while since I used it, but when I used it, it worked like a charm.

You buy your own eshop games/cartridges and use nxdumptool to rip them into either nsp or xci files along with any updates or dlc that you installed along the way.

use https://github.com/DarkMatterCore/nxdumptool/releases

It's possible to dump switch games from a hacked switch using this tool: https://github.com/DarkMatterCore/nxdumptool/releases

NX Dump Tool: Only useful if you have physical copies of games you want to dump - https://github.com/DarkMatterCore/nxdumptool/releases

After you've done all that, you need to install NXDumpTool and use it to transfer your games to your micro SD card.

Have you checked AIO? There is a good chance that FW its already there.

You can also grab it from their GitHub, you should be able to get some info there

put this on sd https://github.com/HamletDuFromage/aio-switch-updater update

Now as for the 2nd section you can just get the official firmware through AIO updater. After getting the OFW just follow the third section and you should be good to go.

Use AIO Updater
