Revealing the Headphone and Car-Kit menus
Please note that if you do these next tricks, 


the new menus can't be erased without retoring 


the factory default settings. To do these tricks 


you need to short-circuit the pins on the bottom 


of the phone next to where you plug in you 


charger.

1. To activate the "Headset" menu, you need to 


short-circuit pins "3" and "4". After a short 


time the word "Headset" will be shown in the 


display. Menu 3-6 is now enabled.
2. To activate the "Car" menu, you need to 


short-circuit pins "4" and "5". After a short 


time the word "Car" will be shown in the 


display. Menu 3-7 is now enabled.

THE REBOOT TRICK
This should work on all software versions of the 


6110.
1. Go to the Calendar (Menu-8)
2. Make a note or reminder.
3. Enter some text into the edit box.
4. Hold "Clear" until the whole text is cleared, 

then press "Back".
5. Press "0". The main screen will now be 


showing but a space appears on the screen. (you 


can't see it)
6. Enter 4 digits (e.g. 1234).
7. Use the down arrow to move the cursor to the 


left side of the numbers and the space (Down 


arrow twice).
8. Now enter 6 digits and press the call button.

Wait for a few seconds, the screen should start 


to flash and reboots. It should alsowork on 


other menus like the "Profiles" menu.

EFR CALL QUALITY
To activate EFR (Enhanced Full Rate) Enter the 


code-
*3370#
This improves call quality but decreases 


batterylife by about 5%
To deactivate it, Enter the code-
#3370#

THE JAMES BOND TRICK
If you short-circuit theleft middle and right 


pins on the bottom of the phone with all 


connections touching each other, the Nokia 


software hangs! The profile "Headset" will be 


activated. Before you do this just activate the 


"Automatic Answer" in the headset profile and 


set the ringing volume to "Mute". Now you can 


use your phone for checking out what people are 


talking about in a room. Just place it under a 


table in a room and call it. The phone receives 


the call without ringing and you can listen to 


what people are saying.

NETWORK MONITOR
There is a hidden menu inside your Nokia phone. 


If you want to activate it, you'll have to 


re-program some chips inside of your phone.
Check your software version. You can only 


continue if you have v4.33, v4.73 or v5.24.
Take apart the phone.
De-solder the EEPROM (ATMEL AT 24C64).
Read out the data with an EEPROM programmer and 


save it to a file (Backup).
If you have v.33 or v4.73, change the address 


"03B8" from "00" to "FF".
If you have v5.24 then change the address "0378" 


from "00" to "FF".
Write the new data to the EEPROM and solder it 

back to the phone,
Power on your phone and you should have 


"Netmonitor" enabled.
The Network Monitor gives you the following 


information.

Carrier number
MS RX Level in DBM
Received signal quality
MS TX power level
C1 (Path loss criterion, used for cell selection 


and reselection). The range is -99 to 99.
RTL (Radio link timeout).
Timeslot
Indication of the transmitter status
Information on the Network parameters.
TMSI (Temporary Mobile Subscriber Identity).
Cell identification (Cell ID, Number of cells 


being used).
MCC (Mobile country code)
MCN (Mobile network code)
LAC (Location area code)
Ciphering (On/Off)
Hopping (On/Off)
DTX (On/Off)
Discard cell barred information

CHECK SIM-LOCK
Note - If you bought your Nokia on UK Vodafone 


or UK Cellnet you do not need to check this 


because they both transmit on GSM900, and they 


don't lock the phones. However if you bought 


your phone on UK Orange or UK One2one your phone 


may be blocked. The reason is that they both 


transmitt on GSM1800. To make a call on GSM1800 


you need what is known as a "Dual band" phone. A 


dual band phone is able to transmit on both 


GSM900 and GSM1800, so they lock the phones so 


you can't use it with any other network simcard. 


If you find that your phone is locked you can 


try different software to unlock it. (we havn't 


found one that works yet), or you can ask your 


service provider who will gladly exchange the 10 


digit code for about £35.
This is how to check the status of the 4 


different locks. Aslo don't try entering the 


wrong number, because after 3 times it will 


block the phone for good.

There are 4 different locks on your Nokia phone.
COUNTRY-LOCK
NETWORK-LOCK
PROVIDER-LOCK
SIMCARD-LOCK
The code to read out the sim-lock status of your 


phone is

#PW+(MASTERCODE)+(Y)#
# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4
The master code is a secret code. The code has 


10 digits, To read out the sim-lock status you 


can enter every combination you want!
"Y" Shows the status of the network-lock. Here 


you can enter a number from "1" to "4". The "4" 


is for the sim-card lock.

SIM-LOCK CHECKS
#PW+1234567890+1# = GIVES PROVIDER-LOCK STATUS
#PW+1234567890+2# = GIVES NETWORK-LOCK STATUS
#PW+1234567890+3# = GIVES COUNTRY-LOCK STATUS
#PW+1234567890+4# = GIVES SIM-CARD-LOCK STATUS.
