Just like major smartphones like Nokia Symbian, Android, and iOS Devices, you can as well hack/unlock your Nokia s40 java phones. Now when I am talking about Nokia s40 I am talking about old and new Nokia java phones such as Nokia3110c, Nokia x2, c3, asha 201, 301 e.t.c. And what I am focusing on in this post is how to unlock Nokia S40 Phones. I hereby present 3 methods of hacking your s40, s40v3, s40v5 Nokia java phones

Introduction to the benefits of unlocking Nokia S40 Phones

Through a custom User certificate being installed on your Nokia S40 java phone, you can now run any Java application that you can personally sign in your PC.

This method lets you bypass permission questions like “Allow network access?  This “application is not from a trusted supplier.” If done correctly, this will get rid of the annoying questions or security prompts from java application. I will provide some screenshots.

Requirements

• A Personal Computer (Desktop/Laptop) with the following software installed:
• DOWNLOAD OxyCube or from this link

OR

• DOWNLOAD MobiMb

This two PC software is used to access Nokia S40 hidden system files. Either of the two will work fine with your phone.

• In addition, Download behappy. This PC software will allow us to sign our java applications. Extract it later.
• Lastly,  Download Darkman.zip. The Darkman Certificate (Is also known as a hacker’s certificate to some web articles). Then extract the zip file.
• An S40 phone I personally tested it on  Nokia 3120 Classic phone. It works finely with S40v5 and newer s40 phones.
• Phone USB Cable

Steps to Unlock Nokia S40 Phones

Step 1.

• Install OxyCube or MobiMB Media Browser on your PC. Get to know more about the software I just mentioned.
• Next, go there to phone “C:\Hiddenfolder\certificates\user” and extract and copy the contents of user.zip to the above path after copying files from the zip archive. “C:Hiddenfoldercertificatesuser”, install the certificate by double-clicking on it. It’ll guide you step by step to perform the installation. After the certificate’s been installed, restart your phone.

Second Step:

• Install “BeHappy“. To use this app, you need a Java app. Drag and drop the java app file (xxx.jar) to the BeHappy Window. I used File Explorer Java App here. The filename is “FileExplorer.jar“.
  An xxx.jad file will be created then–FileExplorer.jad

Third Step

• Rename the two files now–the xxx.jar and xxx.jad to “xxx_jar” and to “xxx_jad“. Just replace the
  “.” (dot) with “_” (underscore). FileExplorer.jad to FileExplorer_jad and  FileExplorer.jar to
  FileExplorer_jar.  Now, Save the two renamed files to Memory Card or Card Reader. Just make sure you copy and paste the files into the root directory.

 

Fourth Step:

• From your phone,  go to the Menu>>Gallery>>Memory Card. There verify the files you earlier copied from your PC.  You should be able to see the two files: FileExplorer_jad and FileExplorer_jar with icons
  marked with question marks.
• Now, Highlight first the FileExplorer… “filename alphabetical .jad” .jar. After highlighting, press
  options then rename.
  “_” (underscore) FileExplorer_jad to FileExplorer.jad.
• Furthermore, Now rename the other file, FileExplorer_jar to FileExplorer.jar after renaming the.jar.

 

Fifth Step

• While renaming, the desired app, Press option then navigate down to Application Access>>Data Access>>Read User Data>> –set it to “Always allowed“
• Do the same to Application Access>>Data Access>>Read User Data>>Add and edit data You can use other apps like BlueFTP, to give your file additional full permission. And under Application access>> Communication.  FileExplorer_jar to FileExplorer.jar after renaming the.jar.

Step 6

You may now try and run the signed Java Application.

Seventh Step:

Proceed to move the app(s) to your desired location on phone. You can now just repeat the Drag
and Drop method in the Second Step until the Sixth for other java applications you may want to
sign. And do not forget to enjoy this wonderful hack.
