Please only connect the cable to your computer and phone when the manual states you should.

A note about 'repairing': a software solution can NEVER repair hardware damage. If your phone has been damaged by water or dropping your phone on a hard surface we can not help you. With repairing we mean that we can fix 'Phone freeze' and 'Phone locked, return for service' messages which often happen after using free 'unlock codes' or after using bad (free / cracked) Samsung unlock software. Messages such as 'User fault on illegal trial' or damaged IMEI's (Check; *#06# - all zeros or ones) can only be repaired using SRSpro accounts.

Difficulty rating: easy
Estimated time: 5 - 8 minutes

What you need:


What to do:

  1. Uninstall 'Samsung PC studio' software and 'Microsoft Active Sync' from your computer
  2. Disable Bluetooth on your phone; this is very important
  3. Disable AUTO KEYPAD LOCK on your phone; also very important
  4. Put the original working simcard inside the phone (if you don't have the original simcard or your phone is in 'phone freeze' mode don't put any simcard in the phone)
  5. Start the SRS client ('Start' -> 'Programs' -> 'Simlock Remote Client' -> 'SRS Samsung Remote Unlock Client')
  6. Login using your SRS username and password and select your model (at A and B)
  7. Now in the white log screen at C you will see short instructions telling you that your phone has to be 'ON' or 'OFF':
    SRS Samsung U600 unlock, phone ON
    Or
    SRS Samsung J700 unlock, phone OFF

    At this moment turn your phone ON or OFF according to the instructions.
  8. a. If your phone is ON and the instructions in the SRS software look like the first picture in step 5 please install the Samsung 2G drivers
    b. If the instructions in the SRS client say '3. Make sure the phone is ON and use Serial or FTDI cable you need an FTDI USB cable and install FTDI drivers
    c. If your phone is OFF you need an FTDI USB cable and install FTDI drivers
    d. If you are going to use a Serial cable you don't need any drivers; connect the cable to your computer and phone and you can proceed. (if you cable has a 9v battery connector you will need to connect a 9v battery also)
  9. After installing the correct drivers Hit the 'Rescan' button at D, the client should detect your Samsung modem driver if the phone is ON.
    An example for a phone that is turned ON (COM numbers can be different and more or less detected ports!):
    Rescanning Ports...
    Detected COM3 - Status: Ready
    Detected COM12 - Status: Ready

    Samsung Modem Detected on COM12

    If the phone is turned OFF you will only see something like (COM numbers can be different and more or less detected ports!):
    Rescanning Ports...
    Detected COM3 - Status: Ready
    Detected COM12 - Status: Ready

    It is not possible to detect FTDI drivers or serial cable. To check on which Comport your FTDI driver is located see -How to check your drivers?- so you can set the 'Comport' at D manually or just try all available ports. If you are using a 'Serial cable' the Comport number will likely be 1 or 2. You will also have to set this manually. You can also try setting the Comport number to both 1 and 2 and try to unlock to see which port works.
  10. When the driver is properly installed and the Com port numbers are set correctly you can Unlock and Repair:
    Repair + unlock ALWAYS use the 'Read Unlock Codes' or 'Read E2P' option and enter repair code and unlock codes manually on your phone as stated in the log screen at C.
    Unlock use any option you like
    *'Reset user code' does NOT unlock your phone, it resets the so called 'user code' or 'security code' to 00000000 (8 times zero) and also costs 3 credits.

5. Driver installation instructions

Installing the drivers is vital for the unlocking / repairing process of your mobile phone. We have learned that if people have any difficulty with our product it mostly comes down to having trouble installing the drivers. That is why we now dedicate a complete section on how to install the drivers with screenshots to make it as easy and understandable for our customers as possible.

We highly recommend Windows XP in favour of Vista because Vista can be more difficult to install drivers. Mainly due to Vista's behaviour of thinking it knows everything and does not allow you to install the correct drivers because it thinks it already has the correct drivers. The only solution to this problem is uninstalling the wrong drivers from your 'Device Manager' and then reinstalling the correct ones. Check -How to uninstall drivers- on how to uninstall drivers.

If you have any questions or trouble concerning the driver installation don't hesitate to contact your reseller's support department.
Please choose which drivers you want to install:


Install Samsung 2G drivers
The 2G Samsung drivers are needed when unlocking / repairing a 2G Samsung phone using the Original Samsung USB cable (which often comes with the phone).


Install Samsung QXDM drivers
The QXDM drivers are necessary to unlock / repair Samsung 3G mobile phones using an original Samsung USB cable which often comes with the phone (cable is also referred to as 'data cable' and 'data link').


Install FTDI drivers
The FTDI USB cable drivers are needed when unlocking a Samsung phone that has to be turned OFF when starting the unlock / repair process. The FTDI USB cable is an alternative for using a Serial cable as many modern computers don't have a Serial port at the back anymore (especially laptops).


Install Vodafone USB PCUI Interface drivers
The drivers needed to unlock the special Vodafone models using the SRS Vodafone add-on client.


Install Broadcomm drivers
These drivers are needed for Samsung phone types identified as 'BCM' or 'BCM2' in the SRS client software.
When you connect the phone with the cable turned on you will get the 'Found new hardware wizard'.


Install Swallowtail (or Shrewsbury) drivers
These drivers are needed for Samsung phone types identified as OMAP2 in the SRS client software.
When you connect the phone with the cable turned on you will get the 'Found new hardware wizard'.


6. FAQ / Troubleshooting

The most asked questions by SRS customers answered, and some very useful extra information in case you have any problems with unlocking / repairing your phone.


What is a FTDI USB cable?

A FTDI USB cable is often also called an 'unlock cable'. This is a special USB cable used to unlock certain Samsung models which can NOT be unlocked using the original Samsung USB cable (the cables that often comes with the phone).

This special cable emulates a serial com port (serial cable) and is needed when a Samsung model has to be turned OFF for unlocking. This cable is used as an alternative to the Serial cable because many modern computers don't have a Serial port anymore.

How to get your FTDI USB cable;
There are many websites selling such cables. Have a look at www.unlocksamsungonline.com/links.php for some good websites with such cables.

How to check your drivers?

Sometimes people have trouble installing their drivers or our software detects the com port numbers wrong due to built-in modems and you need to set the com port numbers manually. Following the instructions bellow will help you check if your drivers are installed and on which port numbers so you can set them manually in our software.

Connect your phone to the computer (in case of 3G phone put it in QXDM mode first)
On XP go to: Start -> Settings -> Control Panel -> (Switch to Classic view ) -> System -> Hardware (tab) -> Device Manager.
On Vista go to: Start -> Type in the following commando in the 'Search box': devmgmt.msc and hit enter.
On Windows 7: Click the pearl button (start button) then in the search box type 'Device Manager', you will see 'Device Manager' in the search results. Click and it opens.

Now press the '+' at the following:
- 'Modems'
- 'Ports (Com & LPT)'

In case of 3G phones
In case of 'MSL' or 'Qualcomm' models using Original Samsung usb cable:
At 'Modems' you should see a device called 'Qualcomm proprietary modem' (or 'ZTE proprietary modem' or 'Samsung HS-USB Modem 9002'). Right mouse click on it and choose 'properties'. Browse to the 2nd tab ('Modem') in the new screen to see on which com port this driver is located. Write this down. This is the number you must select in the dropdown box in the SRS client under 'Select Modem'.

At 'Ports (Com & LPT)'you should see 'Qualcomm diagnostic interface (com xx)' (or 'ZTE diagnostic interface (com xx)' or 'Samsung HS-USB Diagnostics 9002 (COM xx)'). This directly tells you on which com port number it's located. Select this number in the SRS client software in the 'Select Comport' dropdown box.

In case of 'OMAP' or 'BCM (2)' models using FTDI USB cable:
Go to 'Ports (Com & LPT)', you should find the FTDI drivers for your cable here.
This can be identified by different names but search for 'FTDI' or 'USB serial port'. You can directly see on which comport it sits.
Select this number under 'Select Comport' in the SRS client.

In case of 'BCM2' models using DUAL cable (SERIAL + USB)
The Serial part is usually on com 1 or com 2. For the USB part the Broadcomm modem driver is needed (this driver comes with the SRS installer in de folder 'drivers') and you can see this under 'Modems' in your device manager' which can be identified by 'Samsung Broadcomm'.

In case of 'OMAP2' models using Original USB cable
You will need to install the swallowtail (or in case of Windows Mobile phones the Shrewsbury) drivers and search for 'SAMSUNG Mobil Modem Diagnostic Serial Port' under 'Modems'. Right click the device and choose 'properties' and go to the 'Modem' tab to see on which com port it sits. You have to select this number under 'Select Modem' in our SRS software.

For 2G phones:
For 2G phones you only need to select a comport in the dropdown box under 'Select Comport'.

In case you have a trident phone and you are using Samsung original USB cable:
Go to 'Modems' and find your Samsung device here (Name differs per phone model but it will by identified by 'Samsung')
Now right mouse click on the device and choose 'properties'. Browse to the 2nd tab to see on which com port number it sits.
Select the com port number you found in the dropdown box under 'Select Comport'!

In case of Sysol / Swift / OMAP / Trident using an FTDI (unlock) USB cable:
Go to 'Ports (Com & LPT)', you should find the FTDI drivers for your cable here.
This can be identified by different names but search for 'FTDI' or 'USB serial port'. You can directly see on which comport it sits.
Select this number under 'Select Comport' in the SRS client.

Tip; Select your Samsung model faster from the dropdown list

As you might have noticed we support over 1000 different Samsung models, finding your model in the dropdown box can become somewhat annoying especially if you unlock phones on a regular basis.

To select your model much faster you can do the following:
1. Click on the 'down arrow' right of the dropdown box with your mouse. The text 'Select Phone' will now be highlighted.
2. Now type your phone model, or just the first letter of your model. You will see the list jump to the models starting with the letter you typed and if you type more of the characters of your model you will see the list jump closer to your model.

What is a Serial cable

A Serial cable is a cable made to connect with the Serial port on your computer. Many modern computers, especially laptops, don't have this connection anymore. If your computer has a serial port it will be located at the back of your computer. It looks like:
Serial Port

How to uninstall drivers

If you have problems with our drivers this could be the result of a conflict with other already installed drivers. If you are using Vista it might think it has the correct drivers for unlocking but it actually doesn't. In that case you need to uninstall the drivers that are wrong to be able to install the correct drivers.

To uninstall drivers go to:
On XP: Start -> Settings -> Control Panel -> (Switch to Classic view ) -> System -> Hardware (tab) -> Device Manager.
On Vista: Start -> Type in the following commando in the 'Search box': devmgmt.msc and hit enter.

In the example we will uninstall the 'Samsung CDMA driver'. Uninstalling works the same for all other drivers (Note that some of the drivers only show when the phone is actually connected).
Device Manager

Right click with your mouse on the device (Samsung CDMA driver in our case) and choose 'Uninstall'
Device Manager
You will receive a warning asking you to confirm you are removing that device from the system. Please confirm and you are done.

System Requirements and incompatible software list

The following System requirements and restrictions are needed to run our software:
We highly recommend Windows XP pro SP3, but other Windows XP versions will work without problems also. Apple Mac computer are NOT supported by our service.

Our solution does also work on Windows Vista but we do not recommend this as Vista is a very bad OS and it can give you difficulty with installing the drivers. To run our software on Vista you have to run it as 'administrator' by right clicking the 'Samsung Remote unlock client' link in your start menu and then choose 'run as' and then choose 'administrator'.

Other supported operating systems:
Windows 98 (with VB runtimes installed)
Windows NT (with VB runtimes installed)

Windows 7

Technical specifications:
Min. 128mb internal memory
Min 128kbps Upload and Download stable internet connection*

* When unlocking 3G models do NOT use a 3G modem and uninstall any software related with 3G modems. These conflict with the drivers used for unlocking

**64 Bit Systems are NOT recommended. Some people have made it work while unlocking 3G phones with QXDM driver but any other drivers will NOT work.

Incompatible software
Software that can conflict with our software while unlocking. If you have any of this software we highly recommend to uninstall it before unlocking / repairing:
-Any software that comes with 3G (USB) modems (fast internet via 3G dial up USB modems)
-Samsung PC studio
-Microsoft Active Sync
-Windows Defender (worthless software anyway)
-iTunes connector (*only in some rare cases)
-Nokia Suite (*only in some rare cases)
