(using a data cable)
If you want to unlock one of these Nokia phones:
2100, 3210, ,3310, 3330, 3410, 402, 5110, 5210, 5510, 6110, 6150, 6210, 6250, 7110, 8210, 8250, 8850, 8890
(I don't have a list of US variants but they have very similar names 5110 = 5190)
then please read the Nokia unlocking tutorial below:
UPDATE YOU CAN NOW UNLOCK THE ABOVE HANDSETS WITHOUT A CABLE READ MY NEW
These phones are classified as DCT3 (or DCT-3) handsets and have now been fully cracked. You can flash them (upgrade the software), unlock them and even modify the flash to create your own custom menus! In this section we will concentrate on unlocking them.
Unlike DCT4 Nokia's there is no free software to calculate unlock codes for DCT3 Nokia's (not yet anyway :-))). If you want to unlock a DCT3 Nokia WITHOUT a cable you must pay for an unlock code (visit my site advertiser by clicking on the banner at the top of this page). To Unlock theses phones yourself you must use a data cable!
Having said that unlocking DCT3 handsets is still very easy and there is a vast range of software that will do it. In my opinion the best is Nokia Tool by Rollis 1.8 (rollis works fine with either pure mbus cables or m/f bus cables!)
Download and run the rollis software. Connect the phone to your data cable and switch the phone on. This software is very clever in that it will auto detect which type of data cable you are using (either pure M bus or auto switching F/M bus). To get the software to auto configure itself for the data cable and com port you are using just press the following button (found at the top right of the tool bar):
After a few secs you should get a "Found Phone" message. (if not check you data cable is well connected to your handset). Now the software is configured press the "read phone info" button at the top left of the tool bar.
You will see the phone information displayed in the text boxes. Most of this is not important. But do have a look at the status of each of the four locks. If any one or more of these are closed then the phone is locked. To unlock the phone just press the "Clear SP Locks" button.
THAT'S IT!! Your phone has now been unlocked. I would not recommend playing around with the other features/buttons unless you know what your doing!!!!
Having problems with the above tutorial??
If for some reason you are having problems with the above tutorial you should post any questions in my forum. Also it is well worth checking out the following unlocking tutorials from other GSM sites (which use different unlocking software but just as good)!
Unlocksmith DCT3 unlocking tutorial (his web site has disappeared)
An excellent tutorial from unlocksmith, not only does this show you how to unlock your phone but also how to re-lock it!
Another very good piece of DCT3 unlocking software is Eeprom Tools 3.1 / 4.0. This can be used to unlock all DCT3 handsets but also includes 9210 support! I will write a tutorial for this software when I get time. (if you know a good link to an unlocking tutorial that uses this software mail me and I will add it here)
If you know of any other good DCT3 unlocking tutorials please contact me and I will place a link here!
