Some of these phones are branded and come with an ugly splash screen from the carrier, and you might want to change that into your own. The only things you need is a Engeneering SPL or a Hard SPL, which you should how to get from the previous blog posts I made, and either a Linux operating system with Imagemagick installed and this application for Windows or this application for Linux (has to be build from source) to create your own splash images.
First step is to convert an existing image with the dimensions 320×480 pixels. The image file has to be supported by imagemagick, so it has to be either gif, jpg, png, bmp or whatever is supported. This image file has to be converted into a 256 colour 8-bit raw image file:
convert -depth 8 splash.png rgb:splash.rawCheck that the splash.raw file is exactly 460800 bytes.
When you have the raw with the correct size, we need to compile the rgb2565 application it is done by running:
gcc -O2 -Wall -Wno-unused-parameter -o rgb2565 to565.cWhen you have the application compiled the raw image has to be converted to a format the phone understands:
rgb2565 < splash.raw > splash.raw565Check that this new file is 307200 bytes, otherwise do not flash it to the phone. We have now created the splash image for the phone. You can do the same in a Windows environment with the application mentioned in the start of this blog post. It should be obvious how to use it.
Second step is to flash the splash image to the phone. Start the phone in fastboot mode by holding back+end/power, also make sure you have the AndroidSDK on you computer installed and have the tools in your PATH.
Then make sure that the fastboot device shows up on you computer:
fastboot devicescd to the folder where the splash.raw565 is and execute the following commands:
fastboot flash splash1 splash.raw565fastboot rebootIf you want it to show up for longer (only for pre-cupcake):
fastboot flash splash1 splash.raw565fastboot flash splash2 splash.raw565fastboot rebootThe phone reboots and you should now see your splashscreen, enjoy 
This is how my current splash looks like:

If you want me to do the work for you, you upload the images somewhere and send me the links.
The first part of this how-to is for a Linux based operating system. For windows use the application mentioned and linked to. Direct link:

You should start the exe located in bin/Debug/

Hi,
I really want to thank you for this awesome tutorial! I managed to change my ugly custom Vodaphone splash image.
I was wondering if there is an application for Mac OS that can do this, in case I want to use my custom images?
Thank you.
