Codeignitor Session Example

Hi folks!, This simple post will explain Codeignitor session management in a vary simple coding example. In the first controller (s1.php) the sessions will be created. The send controller (s2.php) will print the session data and destroy previously added data. The third controller will again try to print the same data.

S1.php

load->library('session');
  $this->load->helper('url');
 }
 
 /*the first loading function*/
 function index(){
  echo "S1";
  $session_id = $this->session->userdata('session_id');
  echo "Session Id: ".$session_id;
  /*create session variable*/
  $this->session->set_userdata('uname','Anne');
  $data = $this->session->userdata('uname');
  echo "Newly Created Session var: ".$data;
  /*go to anotherpage link*/
  echo "<br>< a href=\"".base_url()."index.php/s2"."\">s2<a>";
 }
}

S2.php

load->library('session');
  $this->load->helper('url');
 }
 
 /*the first loading function*/
 function index(){
  echo "S2";
  $session_id = $this->session->userdata('session_id');
  /*get data from session and print*/
  $data = $this->session->userdata('uname');
  echo $data;
  /*destroy session*/
  $this->session->unset_userdata('uname');
  /*goto another page link*/
  echo "<br>< a href=\"".base_url()."index.php/s3"."\">s2<a>";
 }
}

S3.php

load->library('session');
  $this->load->helper('url');

 /*the first loading function*/
 function index(){
  echo "S3";
  $session_id = $this->session->userdata('session_id');

  if( isset($data) && !empty($data)){
   echo "Session Data: ".$data;

How to unlock Huawei USB modems

Recently I got the chance to play with a Huawei Dongle. That dongle was locked and I job was to unlock it. I know it is not a big deal, but I took some screen shots and took some notes since I was not able to do a post recently on my blog. OK then that is the story lets do some hack!! ;)

Firstly this is what happen when a dongle is locked for a particular service provider. When we insert a SIM form another service provider it will show a message like the below one.

I taught of a method for unlocking the dongle, I came with a solution and when I do some Google searches people out there has also used the same analogy. What is done by the service providers is they take modem form a third party vendor like Huawei of ZTE and the lock it for their SIM and the sell it. Therefore I taught that updating the firmware will do the magic. My taught was correct buy there was a little problem ;). After modifying the firmware the vendor put a password. When I tried to update the I had to give a password. I do some Google searches and found out some very interesting tool and web site which provide the Unlock code and the Flash code when we provide the IMEI number of the dongle which is printed on it.

Let's look at some jargon.

IMEI - International Mobile Equipment Identity - Used as an identification code for a wireless mobile device like a mobile phone or a dongle.
Unlock Code - As the name implies use for locking and unlocking purposes.
Flash Code - firmware or flash unlock code is required when upgrading the firmware version of a modem

Note that here our interest will be the Flash code since, we are going to unlock the modem. I used the little application call Universal Master Code (do a Google and you will be able to download it) to get the Unlock code and the flash code for the modem. There are several web sites which will offer the same feature. Following shows a screen shots of those.

Then I update the firmware for my dongle. The firmware related to your one can be download (Again do a simple Google search ;) ).

Some of the steps are shown in following screen shots. Please note that you have to use the Flash Code for update purpose, not the Unlock code .

Use the Flash Number as the above password.

At last .... 

Your comments and inquiries are well come on this topic.. Mmm.... I wonder how that simple application calculate those codes.... Is there any algorithm?? It will be interesting to find. I think it is better try to reverse engineer that app and look our selves what is hidden in that application.. That will be an interesting upcoming post... Be with GeekTalkz!! bye!!
