Hey there, so, i just bought the SX pro kit, and then got my license.dat and loaded it in the micro sd card, along with the boot.dat file. The problem is, when i boot up the switch with the dongle and the jig, it goes into the Sx OS screen, and then when i press the Boot Custom FW button, the switch turns off imediatly and i can't enter the SX Os screen again unless i restart the switch.

Try fully powering off the Switch by holding the power button for 12-15sec, if you have not tried this already.

What is your SD formatted, fat32 or exFAT?​

Once you do that, backup your license file from your SD card if you have not already and the boot.dat file even though you can just redownload that.

After that see if you can boot your switch back to OFW with out the dongle or anything, just normally. If that works, reformat your SD on your Switch, power off, copy the boot.dat and license back and then try again.

I already fixed it, turns out that the version i was using didn’t support the latest update of the switch, so once i updated, it started working normally, but thanks for the answer anyway.

I am having the same problem, on switch fw 9.2.0, and the latest SX OS

Do I really have to format the SD card? I don't want to have to resetup 200GB...
