Latest Master Code To Unlock Any Phone without Losing Data

Anytime I purchased a locked phone, mostly Android phones, my go-to move was to factory reset the device. Resetting the device to factory settings worked fine, at least until Google introduced Factory Reset Protection (FRP) lock.

What I didn’t know for a very long time was that these phones had secret codes programmed into them, which you could use to access hidden features such as unlocking, testing, displaying IMEI numbers, etc.

These codes can come in handy depending on your situation, which is why this article will show you the master code or codes you can use to unlock your device and some alternatives you can use in case the codes don’t work.

Part 1. What is The Master Code to Unlock Any Phone?

As the name suggests, a master code is a combination of digits you can use to access hidden features or settings in a phone. It enables you to unlock your Android phone without losing data.

To say that there’s one master code to unlock any Android phone may or may not be valid. It could be true because most Android phone brands tweak stock Android to meet their needs. If that is the case, then the code below should work for every Android phone.

  • Reset Android
  • Delete Google account settings

On the other hand, it could be false brands because some of these Android phone brands might change the master codes while modifying the stock Android to meet their requirements.

With that in mind, let’s look at some phone brands and the various master codes you can use if the Android restore code doesn’t work.

Nokia Master Codes

Code Function
*#7370# Remove security code (Format completely)
*#7780# Reset settings

Samsung Master Codes

Code Function
*2767*2878# Remove security code (Format completely)
*2767*3855# Reset settings
*2767*688# Sim unlock

LG Master Codes

Code Function
*#9999# Formatting

Alcatel Master Codes

Code Function
###337*07# Reset
**0102# Formatting

Sony & Erickson Master Codes

Code Function
>*<<*<* Unblocking
*70*80*700# Formatting

Motorola Master Codes

*#311# Remove Security Code

Master Codes for Chinese Phone

Code Function
*#66# Format phone
*#987*99# Reset
*#12345# More format codes

It is worth mentioning that these codes may not remove the lock directly, for example, removing the screen lock. Instead, they reset or remove the feature that the lock is built on.

Part 2. How to Use The Master Codes?

You’re probably wondering how one uses the codes we have mentioned. When locked, Android phones will only allow you to make emergency calls. That is where the magic happens.

To use the master codes mentioned:

Step 1. On the lock screen, tap the dial or Emergency call button.

Step 2. Enter the appropriate unlock code, then dial to unlock the phone.

Part 3. What If The Master Code Doesn’t Work?

Like every other tech solution, the codes we’ve seen mentioned may not work for everyone. In such cases, you should consider using professional unlock tools or brand-specific solutions such as Google’s Find My Device.

If the codes didn’t work for you, then try the following alternatives:
