aio-switch-updater VS Ultimate-Guide-to-Migrate-SXOS-SX-Core-to-Atmosphere

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

I also came across this guide (https://github.com/dsync89/Ultimate-Guide-to-Migrate-SXOS-SX-Core-to-Atmosphere) but again, outdated info.

If you need examples of boot ini pointing to Hekate or straight to Atmosphere, someone did it alongside slightly older guide to switch from SX CFW to it

I was an SXOS user that's come back to see SXOS no longer exists, and the slog of upgrading is a horrific, multi-day long process involving 50 page long guides (https://github.com/dsync89/Ultimate-Guide-to-Migrate-SXOS-SX-Core-to-Atmosphere), and watching awful tedious youtube videos.

Yes, you can install atmosphere on your console. Follow this guide very thoroughly: https://github.com/dsync89/Ultimate-Guide-to-Migrate-SXOS-SX-Core-to-Atmosphere

Now i wanted to migrate from sx os to atmos and update the switch, so i followed this tutorial (i know files inside is outdated) https://github.com/dsync89/Ultimate-Guide-to-Migrate-SXOS-SX-Core-to-Atmosphere Until step 2.1b and the switch wont boot only blue light blinking (to turn if off i press power&vol+)
