So you fancy generating your own unlock codes? And why not you can make a few quid by selling unlock codes to friends and family etc. Recently the software that generates these unlock codes has become available for FREE!!!!!!!!!!!!!!!
Free Software (JIC Unlocker)
At present the most mainstream DCT4 unlocker is a piece of software from JIC. This unlocker was actually stolen from a company called JIC Electronics a little while back. It is very easy to use as it consists of only one button!
Nokia are continually improving the software within their handsets. Mainly these improvements consist of small bug fixes but recently Nokia improved the service provider lock protection.
What this means is that if your handset has a later version of software it may be more difficult to unlock. (You can check your software version by typing
*#0000# into the phones key pad)
Download the JIC DCT4 Unlocker
This software works on all operating systems, BUT on XP you may need to right click the executable file, select properties and change the compatibility mode to windows 98.
JIC software works 100% with pure Mbus cables and does not work with M/F bus cables. (The software cant put the phone into test mode when using M/F bus cables). But there is a way to make the program work with auto switching M/F bus cables, so read on!
What if you have an M/F bus?
If you have an auto switching M/F bus cable then as mentioned above you cannot use the JIC unlocker. The reason for this is that the program fails to put the phone into test mode. So before you can use the JIC unlocker you must use another piece of software to send your phone into test mode. Download and unzip DCT-4 TestMode By SAJ1UK
Connect your handset to the M/F bus data cable and run DCT-4 Test Mode By SAJ1UK. Press the button "Put Phone in test mode". After a few seconds the phone should display the words "Test mode" on the screen. With the phone now in test mode you can exit from the Test Mode program and run the JIC unlocker. (leave the phone connected to the cable at all times)
When you click the unlock button on the JIC program the phone is already in test mode therefore the program can now successfully unlock your handset.
What software versions can be unlocked using the JIC Software?
The JIC software can unlock the following software versions:
3510: All versions
6310: All versions
6310i: All versions up to but not including 5.10
6510: All known versions
8310: All versions up to but not including 5.57
8910: All known versions
NOTE: 6610 and newer models CAN NOT be unlocked using this software
