This is just a small thread with a list of dialer codes known to the LG G Stylo These dialer codes work for me. If I am missing anything please let me know and I'll add them to the list Disclaimer: I am not responsible for anything you do with these menus or features. I am not responsible for bricked devices or damage to your carrier connectivity. If your phone blows up it's on you THESE WILL ONLY WORK ON SPRINT VARIANTS! (Boost/Virgin/Any carrier who goes through the sprint network) Metro/TMO Codes: *#*#4636#*#* Dialer Codes: 5689#*770# LG Hidden Menu ##3282# (DATA) Service Programmu Menu (Requires MSL/Master Lock Code to edit values) ##3424# (DIAG) DIAG/Diagnostics mode toggle (Requires MSL/Master Lock Code) ##786# (RTN) Accesses the RTN menu ##72786# (SCRTN) Erases OTA provisioned Information (Forces Reboot and a Reactivation on boot will be required) ##873283# (UPDATE) (Forces an Update [Activation/PRL Update/Firmware upgrade]) ##564# (LOG) System Error Log Menu ##8378# (TEST) Accesses the test data menu (Requires MSL/Master Lock Code) ##33284# (DEBUG) Accesses Hardware Debug Menu All of these have worked for me and should work for all of you out there.
