Reset nokia security code

[HOW TO] Reset Nokia Security/Lock code to 12345

Sponsored Links

We previously discussed about this trick in the past here . Today I am going to explain the same method in more detail.Download the mdl file from the link given at the end of this article.


(You will need a card reader for this)

1) Remove memory card from your locked Nokia mobile phone.

2) Put your card into card reader and connect it with your computer. Create
the directory System\\Recogs and copy thc-nokia-unlock.mdl into this directory. So at the end your file will be in System\\recogs directory of your mmc. (System folder will be hidden by default, so make sure you can view hidden files and folders)

3) Remove the Memory Card and place it into the locked phone.

4) Now start your locked phone and wait for some time when it asks for the code. Let this tool reset the code for you. Wait for 2 minutes and then enter 12345 in the code box.

5) Done. Your security code will be reset to 12345.

This method is tested on Nokia N72 and it’s 100% working. Ask me if you need any help on this.

    my keypad is locked with a security code. i changed the default code and now i can’t open it. either i pressed the wrong numbers when i changed it or i forgot what i pressed. how do you create a directory in a memory card? i can only create folders.

    create System/recogs in root directory of your mmc. Put it in your mobile. Restart your phone. Wait for a minute when it asks for code. Then enter 12345 as your code. It should work.

    Both the links given here are working.

      how do you create system\recogs in root directory?
      the only folder that comes up on mine sounds like a temp folder.

    Hey bas

    I tried using it on the Nokia 5310b and it doesn’t seem to be working. I created a System/Recogs directory in the Root of my card, then I tried just creating a Recogs folder and I also tried putting the thc-nokia-unlock.mdl file directly into the root directory of my memory card, but they all didn’t work. I waited about 5 minutes in the security codes screen then entered 12345 and pressed ok, but it says code error.

    Can you help me with this?

    Hi Bas, thank you so much for the respond but I tried the free user one, it says, the file you download only available for premium only, so do you know how to solve my problem, please ? Thanks

  18. bas

    @ Bobby
    Yes it will work on nokia 5310
    and the site which you are talking about is I guess. There is an option available to download as a free user. Select that one and try to download.
    You can extract the downloaded file using Winrar or 7-zip extractor. After extracting that file read this post

    Hope this will help you. If you need any more help plz feel free to ask here.

    n what to do if i want to reset nokia 6300’s security code.plz reply if u have any solution for it . thnx

      insert your memory card in card reader. Connect your card reader to your PC. Now open your memory card drive using my computer. There go to system folder. It might be hidden. So first unhide it. To do this click on Tools->Folder Options-> View
      There uncheck “Hide protected operating system files” and check “Shoe hidden files and folders”. Now see in the systems folder. There must be directory named “recogs”. If it is not there create one. And paste this mdl file there.

        1. eget

          dw about that, i found the solution.
          but my memory card doesnt have a syste folder?
          do you want me to create one?
