[Tutorial] Create your own bootup logo for Amlogic based android devices. (S912, etc)

[cOOLio]

It cost me days to find out how to create my own Full HD bootup logo, for my upcoming custom Yundoo Y1 S912 ATV rom.
Because the build in function of the Amlogic CustomizationTool (I used the latest one v2.0.8) didn't work properly.


Needed (free) Tools

• Gimp (or any other image program that could create 16 bit bmp files)
• 7Zip (or any other compression tool that could create gzip files)

The making of ....

1. Create your own boot logo with the image resolution of 1920 x 1080 (Full HD / RGB color)
2. Export the image as bootup.bmp with the color setting 16 bit - R5 G8 B5
3. Compress the image with 7Zip and select gzip as file compression container.
   File input = bootup.bmp (size 3 - 8 mb)
   File output = bootup.bmp.gz (size 30 - 80 kb )
4. Rename the compressed bmp file: bootup.bmp.gz >> bootup
5. Replace the bootup file at the folder ..\tmp\level2\logo_res\bootup
6. Pack your rom with your own tiny custom bootup logo, that needs less than 1 sec. to load

Done

This is a couple months old but i found it to be very helpful so here is some additional steps if you are a new linux user.

By the screenshots it looks like you are running ubuntu. For anyone interested here is the linux info needed:

Get 7zip & GIMP
sudo apt-get install p7zip-full gimp

3. Compress
7z a bootup.bmp.gz bootup.bmp

4. Rename
mv bootup.bmp.gz bootup

cOOLio thanks for the info!
