prodinfo must be the one that you already got before you booting incognito and if you have restored your original firmware just go to setting and check the switch serial number
yes it is and it's no longer xaw000000000000
i just did think that i had to go to buy another switch but luckily i did use recover software to take prodinfo back that i had accidentally deleted and do exactly what you instruct me
i have prodinfo backup so what should i do now
auto
i do have my prodinfo backup but i don't know how to restore it
can you show me how to do it ??
Thank you
