Here is displaying all kind of Ericsson T28,T18 and GF768 codes.You can using this code and repair your phone easily

Ericsson T28

*#06# for checking the IMEI (International Mobile Equipment Identity)

>*<<*<* for checking the firmware revision information (software release) >*<<*<*> 1-row text strings. if pressing yes you can check the phones text programming in currently selected language.

>*<<*<*>> n-row text strings. if pressing yes you can check the phones text programming in currently selected language.

The Service Provider (SP) Lock
The Service Provider (SP) Lock menu is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it! The cell phone will however accept another SIM card from the same operator.

To activate/deactivate this lock one needs a special secret code that is not available to the end user.

Here is how to activate the menu:

<**< >Ericsson T18

*#06# for checking the IMEI (International Mobile Equipment Identity) Information you get from the IMEI:
XXXXXX XX XXXXXX X
TAC FAC SNR SP
TAC = Type approval code
FAC = Final assembly code
SNR = Serial number
SP = Spare

To access SIM-Locking menu of your phone, press: < * [CLR] < >

Ericsson GF768

To return the language back to english on the ericsson GF768, just press left ( <-- ), zero four times (0,0,0,0), and then right ( --> ).

Ericsson AH 230/238 PROGRAMMINGPress and hold down FCN while entering the digits 9 8 7. You must enter the digits within ten seconds.
The text "SER NUMBER" is displayed along with the telephone's electronic serial number. The number contains 11 digits, so the most significant digit is shown for one second, followed by the other 10 digits.

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.

Ericsson 218 and 337 Secrets codes

Ericsson 218/337

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 <> 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 <>

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

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
To enable, send the following:
EEWR 047A 01
Wait for the OK prompt, power off* the phone and disconnect it from the interface cables. Powerup and browse through the menus.
To diasable, send the following:
EEWR 047A 00
Clearing Electronic Lock
To clear the electronic lock you have to clear the EEPROM address range 045B to 0466 by sending the commands:
EEWR 045B 00
EEWR 045C 00
EEWR 045D 00
EEWR 045E 00
EEWR 045F 00
EEWR 0460 00
EEWR 0461 00
EEWR 0462 00
EEWR 0463 00
EEWR 0464 00
EEWR 0465 00
EEWR 0466 00
Disabling the Service Provider Lock
To disable send the following command:
EEWR 1587 00
To enable send the following command:
EEWR 1587 01
Experimental Commands - Use at own Risk
To dump the application software send the following:
PREA

Bank range : 00..7F

Address : 0000..BFFF

Bytestoread : 0000..BFFF
The "additional" value returned at the end are the checksum value
for the returned program memory bytes. Note, the byte-values are
always returned in format 0000 and NOT 00.
PREA FF
Returns the application checksum, takes a few seconds.
Notes on the PH 337
1. Calculator mode is NOT available on all PH sw versions.
2. Invoking Calc/RBS mode not available for GH337 sw versions below
R2A
3. SPCK attempts can be changed to 50 instead of the std 5 tries
4. The instruction LIME returns ERR but does not screw up phone
5. The instruction IMEI returns the IMEI no.
6. Pressing YES in response to FLASH? does screw up the unit.
COOL STUFF TO DO
Set ComPort to 115200bps, 8 data, 1 stop, no parity and watch all t
he phone commands on the screen and so on. Make a call and see what
happens as well as shutting down.

The Service provider (SP) lock is used to lock the cell phone to the
SP's SIM card. Once the cell phone is locked to a specific operator,
if one inserts a SIM card from a different operator the phone will
refuse to accept it! The cell phone will however accept another SIM
card from the same operator.
