I have it. Why do you need v1.2?
Because need update my Switch in 5.1 (without Internet, no want ban), and with TX update 1.4 no can.

With games in XCI can update, if put a cartridge (no can in 1.4, just in 1.2, but no can donwload old version) i can update my old version Switch witout Internet, and can play new games, do you understand?

I'm not sure I understand. There is no reason to use an older version of SX OS. 1.4 is the latest at this time.

If you insist on using the older version, you can download it here: CLICK
i didn't understand a single line of that xD

People like me, used SX OS 1.2 to update the firmware offline using a .XCI backup, and he wanted to do the same.

There is a tutorial for doing this.
