A question that has been asked a lot lately is what is the difference between Android FRP Lock and Samsung Reactivation Lock?

Well, many of the most recent Android Phones including models from Samsung, HTC, and Sony can become stuck on activation screen requesting for your ID and password, while others are requesting your Google Account. Samsung phones will ask for a Reactivation Lock ID & password, so that people can be identified along the same lines as apple iCloud Lock. To clarify things, here we provide detailed information on the difference between the two.

What is Factory Reset Protection (FRP) Lock ?

Android Factory Reset Protection (FRP) is a new feature designed to protect your device. It has been added to several Samsung devices that are running Android OS 5.1 or higher.

This feature enables you to set up your device to prevent other people from using it in the event that it has been reset to factory settings without your permission.  For example, if your device is lost, stolen, flashed, or wiped, only someone with your Google account or screen lock information can perform a factory data reset and use the device.

When a device is factory reset, the device will not be able to be setup without the user entering the Google Account associated with the device (for hard reset) or screen lock information (for reset in Settings menu). It’s essential that you set up a Google account in order to use the FRP feature.  It is also highly recommended that you set a secure screen lock on your device.

What is Reactivation lock and how do I use it on my Samsung?

Similar to FRP, Reactivation lock lets you use your Samsung account to prevent others from activating your device if ever it is lost or stolen. With Reactivation lock turned on, you will be required to enter your Samsung account credentials (sCloud) prior to performing a factory reset on the device, so your Samsung account login should be something you can easily remember.

When you insert a SIM card from a different cellphone operator than the original, your Samsung phone asks for an unlock code and prompts you to enter the “Network blocking control key” or “SIM Network Unlock PIN“. So at this point you decide to go online and receive a cellphone unlock code.

If upon entering your unlock code you receive a message such as:

– “Failed to unlock network”,
– or “Failed to request“,
– or “Your attempt failed“,
– or “Unlock Code Request Unsuccessful

There are three possible scenarios:

  • Scenario #1 (in 90% of cases):

You (or the previous owner) entered too many wrong codes, it’s what we call in our industry “Phone Freeze”. (if so, see the solutions below).

  • Scenario #2 (In 9% of cases):

Non-original ROM. You (or the previous owner) may have installed or flashed your Samsung with a Custom ROM that is not genuine (like Avatar, or Cyanogen MOD to name two), therefore the code provided will not work (if so, see the solutions below).

  • Scenario #3 (In 1% of cases):

The code is actually wrong. Yes, we do not claim to be perfect, sometimes the computerized processing of orders produces the wrong code or, very rarely, even Samsung or the cellphone operator has supplied a false code base.

  • Scenario #4 (New since Summer 2015):

Well the last scenario is even worse than the previous one. Since summer 2015 two networks (MetroPCS and T-Mobile in USA) started to release Samsung cell phone coming with an app install by default called “Device Unlock App”. Those are simply not asking for code, and even if you use some secret code to make those ask for a code, they will simply not work. Do not order code if your phone is one of those since the code you will receive will be simply useless.


How to use the code if your Samsung Cell Phone is “FREEZE”

The message “Network unlock failure” or “Phone Freeze” means that someone has already tried to unlock the phone with a bad code, and the number of attempts has exceeded the allocated number of times permitted, (it’s usually a maximum of 3 trials tries for a wrong code). In this case it is very likely that if you bought a used phone, the previous owner attempted to unlock it out with a bad code by visiting an untrustworthy free unlock website.

At UnlimitedUNLOCK, our codes are 100% correct since they come directly from the Samsung factory.

If you choose a manufacturer code, you receive two codes:

Code 1 => NETWORK unlock code or code (called NCK Code).
Code 2 => UNFREEZE (or Defreeze) Key to unlock the test counter (called MCK Key).

The purpose is to “unfreeze” the phone with the code and thereby unlock the phone from the NETWORK.

Methods for removing Samsung Freeze with MCK code

Depending on your model, several methods exist to unfreeze with the MCK code your Samsung:

  • Unfreeze Solution #1:

Turn off your phone, take out the SIM card and then replace it with a non-compatible SIM card
(if the phone application demands it, type the PIN number of the SIM card).

When the message “Phone Freeze” appears, call for the unfreeze code and confirm with the button “call” or “#” or “OK” (Note: be careful when entering this code, nothing will appear on your mobile screen, this is normal, you must enter this code blind.)

  • Unfreeze Solution #2:

Again, insert a non-compatible SIM card into your phone (if the phone application demands it type the PIN number of the SIM card). When the message “Phone Freeze” appears, enter the code: #7465625*638*UNFREEZECODE# (and replace UNFREEZECODE by the MCK Code we provide.)

  • Unfreeze Solution #3:

Insert a non-compatible SIM card into your phone,
(If the phone application demands it, type the PIN number of the SIM card)
Enter the unlock code 1 (NCK / Network): then press OK. Answer the phone “unlocking the failed network”,
Next enter the second code (MCK/Unfreeze), then press OK. Answer the phone “unlocking the failed network”,
Re-enter the unlock code and the phone will be unlocked,
Turn off and restart your Samsung mobile phone.

  • Unfreeze Solution #4:

Insert a non-compatible SIM card into your phone,
(If the phone application demands it, type the PIN number of the SIM card)
Emergency call only: Press CALL button and enter the unfreeze (MCK Code) directly,
The phone will ask you the code for the network, enter the NETWORK code that was supplied.

  • Unfreeze Solution #5:

Insert a non-compatible SIM card into your phone, and turn on the phone,
(If the phone application demands it, type the PIN number of the SIM card)
The phone is blocked, Click Call and enter the following code *7465625*638*CODE#
(where CODE is the unlock code of the operator)

The phone does not accept the code and returns the error:
Phone Freeze. SIM not available. Please contact your operator

Turn off your phone and remove the phone battery
Replace the battery and turn the phone back on
The phone is now unlocked and everything works

Note that there is no trial “tries” limit to enter the unfreeze code, so do not hesitate to keep trying to enter the correct code and then get the ‘unfreeze’ sign with the display inviting you to enter the NETWORK code.

To received the UNFREEZE CODE, make sure you order “FACTORY CODE” 

If you choose the operator solution, which is the cheapest solution, you will receive only the unlock code (NCK Code). For the network code + unfreeze code, choose the option ‘factory code’. It’s usually more expensive but it’s also much more reliable and faster.
