*#7780# - restore original (working) smart settings
*#7370# - reset the smart to factory settings (i.e. all software, contacts, calendar, etc. are deleted - the smart becomes clean!)
ATTENTION! To use the last two codes you will need to enter the phone lock code (default 12345)!
Safe Mode when you turn on the phone - “PENCIL” + “Power Buttion”
Loading into Safe:
1. Turn off your phone
2. Press "PENCIL" (and DO NOT release)
3. Press the power button
4. Hold the “PENCIL” until it is FULLY loaded!!!
*#2820# - unique address of the Bluetooth module of your device (may be needed by other devices that cannot display names).
*#7370925538# - clearing the “Wallet” (for 6600 and higher - which have a “Wallet”).
*3370# (phone must reboot) improves sound quality (using EFR), but reduces battery life.
#3370# - resets the sound quality to normal (cancels the *3370# code).
EFR CODEC (Enhanced Full Rate)
This feature, when enabled, should, in theory, significantly improve the quality of transmitted speech, but, unfortunately, it must be supported by the cellular operator. When it works, the phone's power consumption during talk time increases slightly (about 5%). As far as we know, none of the Russian mobile operators support this function. The principle is based on a different speech compression algorithm (ACELP) and occupies a wider frequency band.
*4720# - enable Half Rate Codec (HFR)
#4720# - disable Half Rate Codec (HFR)
HR CODEC (Half Rate)
Significantly degrades speech quality, but saves battery by about 30%. Again, must be supported by your cellular operator.

Codes for determining whether LOC is installed on the device or not
Your Nokia can be blocked by 4 types of locks:
SPROVIDER-LOCK - 1
NETWORK-LOCK - 2
COUNTRY-LOCK - 3
SIMCARD-LOCK - 4

To check the status of these locks, enter the following line:
#pw+(MASTERCODE)+(y)#, where
- p = press * 3 times
- w = press * 4 times (in the original, on the contrary, w - 3 times, p - 4)
- + = press * 2 times
- MASTERCODE = exactly the thing that was used to lock your device. But to check the status, enter 1234567890
- y = number from 1 to 4

If your phone is locked by an SP (Service Provider) code that is unknown, then try the following:

1. The Pin code request must be enabled;
2. turn on the phone;
3. When asked for a Pin code, press C, then the up or down arrow;
4. press C and hold until the display clears;
5. Now enter the command to change the Pin code, but without changing it;
**04*Pin*Pin*Pin#
This operation must be repeated every time the device is turned on.

Half Rate Codec:
Inclusion:
*4720# - Half Rate will be activated after the phone is overloaded (power consumption is reduced)
Shutdown:
#4720# - Half Rate will be turned off after the phone is overloaded
Enhanced Full Rate mode allows you to get much better sound quality with the same number of bits of transmitted information, but it loads your provider’s network more, and the call time is reduced by about 5%

Half Rate mode degrades sound quality, but unloads the network and allows the provider to pass more calls through it, while the call time increases by about 30%

Questions and comments about secret codes for Nokia Lumia 920

Ask a question regarding Nokia Lumia 920 secret codes

Let's look at how to reset your Nokia Lumia 920 to factory settings.

This article is not a guide to action. All responsibility for the service of your device lies with you.

Hard reset

If your phone experiences a hardware failure, it is recommended to first perform a hard reset to factory settings. This does not erase your Windows Live ID account settings or user data.
Since this phone model does not allow the user to remove the battery independently, it has a special electronic circuit that turns off the power to the phone when certain buttons are pressed.

To perform a hard reset, press and hold the Volume Down and Power buttons for 5 seconds. The phone screen will turn black (the phone will turn off). Then press the phone's power button.

Soft reset/
A soft reset through the operating system returns the phone to the state it was just purchased.

ATTENTION! When performing this procedure, all user data will be erased!
The first thing you should always do is try a hard reset.

Option 1: via menu

This option can be used if you know the lock code.

• Select Menu > Settings > About product > Restore default settings (Settings > About > reset your phone)
• Then you will need to enter the lock code.

Option 2: via secret button combination

This option can be used if the phone is locked and you do not know the lock code.

Step 1
Make sure your phone is turned off. Press and hold the Volume Down and Power buttons until an exclamation mark appears on your phone screen.

Step 2

Use the following button combination:
1. volume up button
2. volume down button
3. power button
4. volume down button

Step 3

The phone's settings will be reset and it will turn on automatically.

Sometimes it happens that the phone bricks or freezes (gears spin) for a long time. To get the phone out of this state, you can reflash it according to the instructions “”, or take it to an official Nokia service center, where they should reflash it for you free of charge.
