Our instructions are GLOBAL instructions for all unlocking services. Instructions about unfreeze are meant for people who have purchased a FACTORY SAMSUNG GENUINE UNLOCK CODES service, which include UNFREEZE code. If you have purchased a carrier unlock code (from you network provider): this service does not include UNFREEZE code. If you have FREEZED your phone, the unlock network code won't help to unfreeze, only unfreeze code will reset freezed phones.
Step 1: Determine the lock level of your Samsung GT-S3770K
If you have ordered unlock codes from our website, you will have been pleased to see that every possible unlock code has been emailed to you.
The unlock codes emailed to you will look something like this:
Unfreeze: 12345678 NCK: 12345678 SCK: 12345678 SPCK: 12345678
Most networks only lock their Samsung handsets with the NCK lock enabled. Therefore you should only need to use this code when following the input instructions (see step 2). However some networks will have dual locks in place (whereby the NCK and another lock is enabled) or they may have just an alternative lock level such as SCK or SPCK.
It is best practice to be 100% sure which lock level is present on your Samsung GT-S3770K, to do this follow these instructions:
Enter the following code into your Samsung GT-S3770K while it is turned on and connected to its locked network.
By this, we mean the connected to the network your Samsung GT-S3770K is locked to (if you are locked to Orange, insert an Orange SIM card into your handset)
Once connected, enter this code: *#7465625#
A menu will be displayed that will resemble the following:
(xxx = Value ON or OFF)
If only the Network lock is displayed saying ON then you will only need to use the NCK code with the instructions below. If you see the Subset lock value as ON then you will need the SCK code and if you see the SP lock value as ON you will need the SPCK code.
The unfreeze code we send you should only be needed if:
Now you know the correct lock level of your Samsung GT-S3770K and thus the correct code required for input, you may continue...
NB: If your Samsung GT-S3770K does not accept the code to locate your lock level, simply move straight on to step 2 of this guide...
Step 2 : Input Instructions
OR (if phone show "Insert Correct SIM Card")
Step 3: Troubleshooting
If your Samsung GT-S3770K freezes for whatever reason and displays the 'Phone Freeze' or 'Return for Service' message then you will need to use the unfreeze code that was issued with your unlock codes.
Below you will see a list of instructions for entering the unfreeze code into different models of Samsung handsets.
Choose the handset instructions closest to your own model if it is not directly available. (i.e. if you have a Samsung i900, consider using the Samsung F480 unfreeze instructions).
NB: Unfreeze instructions are given as an added bonus to your unlock service. This is not the service you purchased and therefore it is provided free of charge.
