Post Reply Email Thread
Note:
This is not bootanimation, this is the splash screen (the boot logo which is displayed when device is switched ON)
This is for Alcatel OneTouch Idol 3 Only..
For other devices, please send me your splash.img so that I can create a tool for you too.

Requirements:
1. Rooted OneTouch Idol 3 (any ROM)
2. Terminal Emulator app

STEPS to create splash.img:

Before proceeding, make sure fastboot is setup properly in your computer (just incase something goes wrong)..

1. For Idol 3 4.7 inch variant, make sure you have a picture in PNG format with resolution exactly 720x1280px.

For Idol 3 5.5 inch variant, make sure you have a picture in PNG format with resolution 1080x1920px or lower.

Note:
For 5.5 inch variants, OneTouch Idol 3 has a fixed frame buffer size of 1MB for splash image, so only very light-weight pictures should be used.
It's recommended to use picture with 3 or 2 colors only, like Black & White pictures.
So you'll have to try many pictures till you get a successful one.
Here's an example.

2. Download & Extract this:
For 4.7 inch variants: Idol_3_4.7inch_Splash_Maker.zip (thanks to @persona78 who created this for 4.7inch idol 3)
For 5.5 inch variants: Idol_3_5.5inch_Splash_Maker.zip

3. Now rename your picture as logo.png & replace it inside "pics" folder of the extracted folder.

4. Finally, run the 'CREATE_LOGO.bat' to create splash.img , which you can find inside the "output" folder after completion.

Note:
For 5.5inch variants, you might get an error like "PICTURE IS LARGE IN SIZE" if it's not possible to create a logo with that picture.
In that case, try any one of these below:
a. Try compressPNG.com to reduce no. of colors in PNG picture.
Upload your picture, click Settings, reduce number of colors to 2, Apply & download it & try again.
b. Reduce the picture resolution.
For example, this picture can edited to something like this.
(Hope you understand what I say)
c. Try some other picture.


STEPS to flash splash.img:


0. Optional: Backup your original stock splash.img by the command:
Code:
su
dd if=/dev/block/bootdevice/by-name/splash of=/sdcard/splash_backup.img
(And transfer to computer, might be needed in future)

1. Transfer the splash.img that you created to your device's Internal Storage.

2. Open Terminal Emulator & enter the following to flash it:
Code:
su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash
(You can also flash from fastboot as given below)

Note:
Incase something goes wrong or device doesn't bootup, flash the stock splash.img from fastboot like:
Code:
fastboot flash splash splash.img
Or flash the attached stock splash zip file from custom recovery.


Credits:
1. @persona78 who provided the splash.img for 4.7inch variant and modified the tool..
2. @GokulNC (myself ) who wrote this script
3. Based on logo_gen.py script

Thanks for your effort

There's something missing in your modification..
It only generates the boot logo..
The splash.img also contains the download mode image..
So if you flash the splash.img created by your tool, when you boot into download mode, you won't see any image..

Anyway, I corrected that mistake and uploaded the tool in OP
Thanks again!

By download mode, I mean the mode mentioned here: [TOOL] Sahara & Firehose Test

I don't know what image is displayed while booting into recovery (the same bootlogo might be displayed I guess)
