(UN)LOCKING YOUR ERICSSON A1018s TO SPECIFIC NETWORK :

A way to (un)lock your cell phone on to the network:
1. Press : <**<
2. Then on the display appear and give you two choices:
Lock to Network ? and Lock to Network subset?
3. Enter the NCK number (code is provided by the SP)
4. You have 5 attemps to do this
5. then your cell phone will work 'only' with the network

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

Try these Codes on your DH-368 phone:
1) Power on.
2) Press 904059 + 'MENU'
3) 'TEST SET' display ...
4) Press 'YES' will display @ then press 1 'RCL' will turn light off
and you will see 'DONE'
5) Press 'YES' will display @ then press 86 'RCL' display 'DONE'
also you will hear static...
You can just enter the channel number (up to 1023) by pressing
'Yes' 3 'CLR' XXXX - channel number to enter a channel directly.
You can also see the signal level on channel by pressing 3 'MENU'.
You can see the ESN number by pressing 'YES' 1 'RCL' 96 in HEX format.
6) Press 3 to exit, now you phone will power down and power up again.
You can install the phone number into the phone by pressing 923885 + 'MENU'

Software update, how?
I have been asked a lot about how to update the software in cellular phones.
The easiest thing to do is to go to the nearest Ericsson
dealer and make him do it for you. Just remember that it is supposed to
be free (a receipt is requiet) so don't let him tell you anything else!
Service Provider 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. (not even to you... or is it ? in case please let me know!)
Here is how to activate the menu:
<**< Lock to Network? if pressing yes you have 5 attempts
to enter NCK.
<**<< Lock to Network subset? if pressing yes you have
5 attempts to enter NSCK.

  Warning: Your phone can be locked to a service provider FOREVER by doing this!

If an invalid code is entered all five times, the menu will exit and be deactivated!

Any further attempt to activate the NCK/NSCK lock Menu will result in the response

"Not allowed"! However the NCK/NSCK lock can be recover through a direct clearing

in the EEPROM.
Tips and Info
Shortcut for Last Dialed call menu...
If you for some reason don't want to enter the 'Last Dialed
calls menu' by using the 'YES' key you can use the following
key stroke instead: First '0' then '#'.
Bat. level indicator when turned OFF...
When the phone is turned off and the phone is not changing -
the bat. level can be seen for a short period of time by pressing
the 'NO' key quick once (it has to be quick!) and then wait for
about 2 sec. The bat. level will now be shown in the display
at its normal position.
Access menu without Sim card ...
To access to the menu in your phone without having a card inside do the following:
type **04*0000*0000*0000# When display say "Wrong Pin" press NO and you have access to the all menus: Info, Access, Settings, Calculator, Clock, Keylock On?, Mail, Phone book.
NOTE if you try this on your phone may stop at Keylock On? menu and you?ll have to take your battery out to turn the phone on again.
Alarm Clock Menu..
Go to MissedCall
Empty the list
Press the -> key for a second or two
The option Menu size turns up
Choose 'yes' and go from there.

An alarm clock turned up too but it never rang. I think this was
because there is no clock in the phone.

Free phone calls using the GA628..

NB! This trick has only been reported working on PREPAID GSM CARDS and in some countries and with some sw versions.
The prepaid GSM SIM CARD is a kind of "SIM card" which only has a sertant amount of credit on it (like a normal phonebox telecard)...
if it can be traced? - I don't know...
Well..here's the trick you dial the no. normally and press YES. While "connecting" is shown on the screen, the following procedure should be carried out:
Press CLR then 0 then # and then NO (twice) so as to switch OFF the phone. You can then still speak on the phone while it is switched off but the SIM card does not record your calls which will lead to FREE phone calls in some countries.. we hope!!

Another variant of the code ..
Make a Call, while the phone says Connecting type 083# (the position 83 must be empty! ), when phone says Pos Emtpy, press the NO key and turn off the phone. If you can make the call with the phone turned off you will face a problem when you need to hang up the phone...the only way for you to do that is remove the battery...???

Fixes in Software version<971009>

After receiving an SMS the prompt >>Message read?<< stayed

on the screen until you pressed YES or NO. This new software eliminated

this "feature" and when you receive an SMS >>Message read?<< stays on

the screen only for a few seconds then it changes into an envelope.
 
 Fixes in Software version <970905>

(and Ericsson 788 - software version 970716)

The error is described as "MS unable to find HPLMN if 30 or more competitor

ARFCN+s have greater signal strength than the HPLMN."

In other words:

if there are 30 or more channels belonging to other

carriers which are stronger than the customer's home network, the phone

will not be able to find the customer's home network.
 
Fixes in Software version <970715>

- The bug of the missing arrow on display when all diverting active.

- Key lock key on display turned around , like in manual. (???)

- An updated GSM operators' list.

- Better and more solid reception.

 Software update, how?
 
 I have been asked a lot about how to update the software in cellular phones.

The easiest thing to do is to go to the nearest Ericsson

dealer and make him do it for you. Just remember that it is supposed to

be free (a receipt is requiet) so don't let him tell you anything else!
 
 
 Service Provider 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. (not even to you... or is it ? in case please let me know!)
 
 Here is how to activate the menu:
 
 <**< Lock to Network? if pressing yes you have 5 attempts

to enter NCK.
 
 <**<< Lock to Network subset? if pressing yes you have

5 attempts to enter NSCK.
 
 Warning: Your phone can be locked to a service provider FOREVER by doing this!

If an invalid code is entered all five times, the menu will exit and be deactivated!

Any further attempt to activate the NCK/NSCK lock Menu will result in the response

"Not allowed"! However the NCK/NSCK lock can be recover through a direct clearing

in the EEPROM.
 
 Tips and Info
 
 Shortcut for Last Dialed call menu...

If you for some reason don't want to enter the 'Last Dialed

calls menu' by using the 'YES' key you can use the following

key stroke instead: First '0' then '#'.

Bat. level indicator when turned OFF...

When the gh688 is turned off and the phone is not changing -

the bat. level can be seen for a short period of time by pressing

the 'NO' key quick once (it has to be quick!) and then wait for

about 2 sec. The bat. level will now be shown in the display

at its normal position.
 
 Access menu without Sim card ...

To access to the menu in your phone without having a card inside do the following:

type **04*0000*0000*0000# When display say "Wrong Pin" press NO and you have access to the all menus: Info, Access, Settings, Calculator, Clock, Keylock On?, Mail, Phone book.

NOTE if you try this on the SH888 your phone may stop at Keylock On? menu and you?ll have to take your battery out to turn the phone on again.
