you'ld have to download pretty good amount of this to do this. Follow step by step to the following procedure:

• Downloads
  
  1. USB Flash Driver ( http://rapidshare.com/files/137908666/IS O-8859-1__driver.zip)
  2. XS++ 3.1 Darwin
  Please download all of these files before proceeding.

1.) Converting to CID52 (if required)If XS++ detects a DB2020 CID49 or CID51 phone, it will automatically ask if the user wants to upgrade.
CAUTION!!! If You Upgrade To CID52, You Can Not Revert Back To CID49 Or CID 51.

2) Backing up GDFS
Backing up the GDFS isn't something which necessarily has to be done when flashing firmware, but it is a very good way to ensure you don't damage your phone beyond repair.

Step 1.
Take battery out of phone and put back in (do not turn phone on). Open XS++ and click Connect. Hold down the "C" button on the phones keypad and connect the USB cable. If this is the first time you flash your phone you will need to install the Flash drivers.

Step 2.
Click on the GDFS tab

Step 3.
Click "Backup GDFS" and wait (shouldn't take more than about half a minute).

Step 4.
Done

3) Flashing the firmware
Step 1.
Take battery out of phone and put back in (do not turn phone on). Open XS++ and click Connect. Hold down the "C" button on the phones keypad and connect the USB cable.

Step 2.
Select the firmwares (make sure you extract them first) by clicking the "..." buttons or simply dragging the file from the explorer to the box (don't get mixed up with FS and MAIN).
Click "Flash" and wait (this takes a while, 6-7 minutes is normal).

Step 3.
Flashing is done, you can breathe now

*) Recovering from a bad flash
*WARNING* flashing a GDFS that did not originally come from that exact handset may have severe consequences. By exact handset I mean your handset, not your friends unlocked handset, YOUR HANDSET!

If a flash goes bad, two things need to be done:
1. You need to flash the firmware for the model you had before (when you did the GDFS backup), and
2. You need to restore GDFS.

For flashing follow from step 3 above. Do the GDFS restore after flashing and customizing the handset.

Step 1.
Take battery out of phone and put back in (do not turn phone on). Open XS++ and click Connect. Hold down the "C" button on the phones keypad and connect the USB cable. If this is the first time you flash your phone you will need to install the Flash drivers

Step 2.
Click on the GDFS tab


Step 3.
Select the backup you wish to restore. Click “Write GDFS”.

Step 4.
Done

This could be a Hardware Issue, and there are also chances that your Firmware is buggy.
You need to Flash your Phone through USB Cable and a software call Phone XS++
SE phone Firmware has two parts.
Main Firmware which contains all the phone software. Main firmware file has the .mbn extension.
FS is a firmware which has settings and all other data like the default images and Ringtones and all other files that is used by phone. It has .fbn file extension.
Before you flash the main firmware make GDFS BACKUP. GDFS backup is very important and not to be missed. You also need to have USB Flash Drivers Installed.
Download Links For XS++ and everything else is here
Download The Video Guide
Note: There are many things that should be kept in Mind while Flashing your Phone like..Full Battery/No Power Failure during the process...etc.
So If you are Ready then Proceed, otherwise contact someone, who had done it .
