Is there any other suggestion please ??
Find your country's original firmware on this website
and place it on your desktop. Remove the battery from your phone and connect it to your computer with a USB cable, then boot your phone into emergency mode. Open the KDZ program and set your phone to 3GQCT and EMERGENCY. Select the KDZ file that you placed on your desktop and run the program. Wait for the program to finish, then unplug your phone from the USB cable and put your battery back in. Boot your phone up normally and everything should be fine.
