Flashing your Nokia 3110c handset

Hi,

I am writing this blogspost to share the procedure to flash your Nokia 3110c mobile handset. Last week I was synchronizing my contacts with Gmail using Nokia suite. It asked me to upgrade my firmware, I clicked ok and suddenly after upgrade my Nokia 3110c started showing abnormal behaviour. When I switched on a white screen flashed 3 times and phone gets switched off. This is due to the fact the upgrade wasn't successful and your nokia 3110c files are corrupted.

I followed few steps and got my phone back just free of cost. If you go to Nokia store they might take huge amount for this.. So here are the steps:
1. Download Nokia Pheonix setup.
2. Download RM-237 files from http://www.mediafire.com/?gdjv2ej1m9328so. Nokia 3110c product type is RM-237 hence downloading firmware files.
3. extract these files and create a folder with name "RM-237" under "C:\Program Files\Nokia\Phoenix\Products\" and paste extracted files in RM-237 directory.
4. Start pheonix. Make sure "NO CONNECTIONS" is selected in connections dropdown.
5. Goto "File> Open Product". Select RM-237 from product type.
6. Goto "Flashing>Firmware Update". Select RM-237 from Product type in dialog that opens on hitting browse button next to product code.
7.Click "Dead phone USB flashing" and connect your phone to your PC with USB cable.
8. Click "Refurbish" and wait for pheonix to flash your phone. Please be patient since it takes 10-15 mins.- don't interrupt in this step.

You will see such logs in output section:

Creating Custom Apex SOAP based Web Service in Salesforce.com's Force.com platform

This blog describes how to create a Custom web service in Salesforce using Apex.

Steps:

Navigate to Setup>Develop>Apex Classes and create new class by clicking new button.
Write a class with "global" access modifier with methods (to be exposed) with "webService" keyword

eg.

global class KartikService
{
    webService static String hello(String Name) 
    {
        return 'Hello '+Name+' ! :D';
    }
}

Then save this class. After saving the class you will view a button "Generate WSDL". Click on that to get WSDL for web service you just created. Save the WSDL file. Let say file name is "KartikService.wsdl"

Now we will consider how we generate clients to call this service in Java and in .Net.

For Java:

We will create new project in Eclipse with name "ApexCustomWS"

You need Enterprise/Partner WSDL to access your Salesforce org. by getting a valid sessionId.

Import Enterprise or Partner WSDL file into the project and generate the web service client for that.

Import the "KartikService.wsdl" into project and generate web service client by right clicking on the WSDL file.

Image below shows code generated for Partner WSDL in Blue box and code for Custom Web service in Red Box

Above step will generate few Java files. Now add a class "Test.java" and write following code:

package com.sforce.soap.schemas._class.KartikService;
 
import java.net.URL;
import org.apache.axis.AxisFault;
import com.sforce.soap.partner.LoginResult;
import com.sforce.soap.partner.SessionHeader;
import com.sforce.soap.partner.SforceServiceLocator;
import com.sforce.soap.partner.SoapBindingStub;
 
public class Test 
{
   public static void main(String[] args) 
   {
       try 
       {
         //Get a stub for calling partner WSDL's login method in order to get SessionID
         SoapBindingStub bind= (SoapBindingStub)new SforceServiceLocator().getSoap();
         LoginResult lr=bind.login("your_username_here", "your_Password+SecurityToken");
 
         //Create a sessionHeader object and set its sessioId property to sessionId 
         //received in loginResult object                        
         SessionHeader sh=new SessionHeader();
         sh.setSessionId(lr.getSessionId());
 
         //Create a service locator object for your custom web service
         KartikServiceServiceLocator locator=new KartikServiceServiceLocator();
 
         //Get URL for your custom web service
         URL url=new URL(locator.getKartikServiceAddress());
 
         //Create a stub for your custom web service with URL for your service and locator as parameters
         KartikServiceBindingStub stub=new KartikServiceBindingStub(url, locator);
 
         //Set the header property of stub with name "SessionHeader" and value as sh-sessionHeader 
         //object created above 
         stub.setHeader(locator.getKartikServiceAddress(), "SessionHeader", sh);
 
         //now make call to custom service-in our case its "Hello(String name)"
         System.out.println(stub.hello("KARTIK"));
        }
        catch (Exception e) 
        {e.printStackTrace(); }  
   } 
}

Its output:

Hello KARTIK !

For VB.NET:

Create a new Winows project or ASP.net project with name "ApexCustomWS"

Add Web Service Reference using Partner.wsdl with namespace name as "sForceService"

Add Web Service Reference using KartikService.wsdl with namespace name as "MyCustomApexWS"

Now the project in solution explorer with these references will look like :

Now we write a procedure "callCustomApexService" that first calls login service and get a sessionID and then make call to custom web service.

Code:

Imports ApexCustomWS.sForceService
Imports ApexCustomWS.MyCustomApexWS
 
Public Class Form1
    Public Sub callCustomApexService()
        Dim stub As New ApexCustomWS.sForceService.SforceService
        Dim lr As LoginResult
        Dim sh As New ApexCustomWS.sForceService.SessionHeader
 
        'make call to login service to get sessionId
        lr = stub.login("your_username_here", "your_Password+SecurityToken")        sh.sessionId = lr.sessionId
        stub.Url = lr.serverUrl
        stub.SessionHeaderValue = sh
 
        'Create stub to call custom web service
        Dim myserviceStub As New MyCustomApexWS.KartikServiceService
        myserviceStub.SessionHeaderValue = New MyCustomApexWS.SessionHeader
        myserviceStub.SessionHeaderValue.sessionId = sh.sessionId
 
        MsgBox(myserviceStub.hello("KARTIK"))
 
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        callCustomApexService()
    End Sub
End Class

Output of above code will be a MessageBox when the Winform will load in memory.
