Codes

Note that you can assign shortcuts to most of these applications ran by these codes using Anycut. For example, *#*#4636#*#* -> Battery information can be accessed directly by creating an "Activity" Anycut shortcut to "Battery information".

Reset

  • Factory format: Remove SIM and microSD cards, start the phone and enter *2767*3855# into the dialer. This deletes all files, including those on the 7GB internal storage, and reinstalls the firmware. This will not affect the camera firmware.
  • *#*#7780#*#* - Factory data reset (same as Settings -> SD card & phone storage -> Factory data reset)

Info and phone settings

*#*#INFO#*#*
  • Phone information (IMEI, Phone number, Current network etc.). Has toggles for ciphering and turning off radio (the latter doesn't turn off the phone radio, however). Extra options are available after pressing Menu: Select radio band, View SIM address book, View fixed & service dialing numbers, Get PDP list.
  • Battery information (status, level, health, voltage, temperature, technology (Li-Ion), time since boot).

Somehow duplicates the Service Mode app.
