Sony Ericsson 218 Codes And Sony Ericsson 337:

To view IMEI number *#06#To view Software Version enter -> * <- <- * <- * CLR (Use with Care)

To activate operator lock <- * * <- (This locks the phone to one carriers SIM card – Use with lots of care)

Press Yes to lock and No to notlock. You can also use the codes below to undo this function. USE AT OWN RISK

I have tested the function Lock to SP… At least on the 337 there’s a submenu: Enter SPCK-code. There are 5 attempts, which is showed (05 attempts). At final attempt the phone beeps as a warning, ‘this is the final try’, when entering the menu… Wrong code exits the menu, so you are not stuck in something… When you have tried to enter the code (wrong) all five times, the menu is deactivated, and you’ll get: ‘Not allowed’ when entering <-**<-

A “secret test mode” can be accessed on the GH337. There seems to be two methods:> * < < * > * displays software version, such as 940810 1310

> * < < * < * displays software version, such as 951024 1054

After entering this mode, the < and > keys scroll through a menu. There seems to be different menus for different versions of software.

Software version number are apparently a date and time stamp.

940810 1310 version commands:

TEXT CHECK – shows 254 messages in current language

INIT EEPROM MMI – resents NVRAM settings (User Settings).

Other, probably more recent version:

FLASH – will restart the phone, to the point of entering PIN numbers.You can’t kill a 337 when pressing YES while it says “FLASH?”, you must connect it to 5/12 volts first to be able to erase the flash-memory.

1-ROW TEXTS – scroll through 174 single line text messages with < and >

n-ROW-TEXTS – scroll through full-screen messages with < and >

950626 1405 version commands:

CXC (number) – The Application software’s “product number”. The GH337/GF337 is always “CXC 125 005″

PRG – Indication for Programming

Programming 337

Set ComPort to 9600bps, 8 data, 1 stop, no parity.

Power on phone by pressing “NO/ENDpwr”.

When performing its powerup sequence the phone will send two “>>”

(ASCII 62 decimal) characters. Within 1 second, reply to it by

sending the 4 character sequence “TP1″.

(I used Procomm Plus with this script “eric.asp”)

[proc main ]

[start: ]

[ ]

[ waitfor ">>" ]

[ pause 1 ]

[ transmit "TP1^M" ]

If everything went fine you should get the “OK” prompt back.

Test the TEST PROGRAM by sending the commands terminated by a :

PROG 0 (shows Test Program product number info)

PROG 1 (shows Test Program product date info)

PROG 3 (Shows Main Application product number info)

PROG D (Shows Main Application product date info)

Programming Calculator and Channel Indicator/RBS

Press # to review

to exit the short NAM- programming mode.

NB:

The Number Assignment Module (NAM) is programmed through the telephone keypad. There are two NAM-programming modes available; the short and the long. The short programming mode is all that is required in most cases. The long programming mode is required if a value set by the short mode is not desired. Either mode may be used stand-alone, or the short mode can be used to set up most of the values and then the long mode can be used to make any changes desired. To enter either of the two NAM programming modes, press and hold down the FCN key while entering a specific series of digits. You must enter the digits within ten seconds. In each programming step, you can either keep the displayed setting or value, or you can change it.

a. To go to the next step, without changing anything, press #. b. In some steps, you can “toggle” a setting from ON or OFF, or vice versa. To change the setting, press any numeric key. In other steps, you can replace a displayed value. To replace a value, enter the digits on the numeric keys. If you enter a wrong digit, you can erase it by pressing FCN CLR.

Pressing * key restores the original value in the display.

Press # to store new setting/value and go to next step.

Press END/PWR in any step to leave the NAM-Programming mode. If you have changed anything in a step, you must store the setting by pressing # before pressing END/PWR.
