LG V10 Port Check Test?
 

I have a LG V10 At&t H900 phone. For me to service the phone I need to enable the diagnostic port by enabling the port check test in the service menu.

Does anyone know what keys to type in?

277634#*# does not work
3845#*900# does not work

Thanks in advance

Hi Andrew,

Thank you for your reply. The codes in the app don't work for this At&t LG V10 phone I have. How did you guys do it? Obviously you guys got it to work since you put IMEI service option in 8.8 update for H900 phone. Please let me know what key input to dial in phone.

Thanks in advance
