Nokia Mobile Tips and Tricks:
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.
1.
Check your software version. You can only continue if you have
v4.33, v4.73 or v5.24.
2.
Take apart the phone.
3.
De-solder the EEPROM (ATMEL AT 24C64).
4.
Read out the data with an EEPROM programmer and save it to a file
(Backup).
5.
If you have v.33 or v4.73, change the address "03B8"
from "00" to "FF".
6.
If you have v5.24 then change the address "0378" from
"00" to "FF".
7.
Write the new data to the EEPROM and solder it back to the phone,
8.
Power on your phone and you should have "Netmonitor"
enabled.

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.
