(These are the only ones I have available at the moment so you might need to pick the closest match for yours)

* - This may or may not be the correct country, I've had to guess with some of the firmwares so if not it will probably be close or a general/normal version.

Step 3 – Download all parts of the firmware into the same folder.

Step 4 - Open one of the downloaded .rar files in WinRAR or other archive manager.

Step 5 - Select the 'dload' folder inside the main folder and drag it onto your desktop.

Step 6 - Open the 'dload' folder on your desktop and check that the file 'update.app' is inside.

Step 7 - Copy the whole 'dload' folder accross to the root of your phones SD card (you may want to use a blank SD for this)

Step 8 - Turn your phone off then press and hold the volume up and volume down keys together and then press the power key.

Step 9 - The install process should start automatically so just wait until its finished.

 

Step 10 - Your phone will reboot automatically after the firmware has finished installing and will take some time to load, this is normal so just leave it to do its thing.

Step 11 – Check that the update has worked by checking the Firmware version by navigating to - Setting->About phone->Build number

Note: The [Firmware Version] should match the last 7 characters of the firmware you downloaded eg C00B213.
