[GUIDE] How to Change Boot Logo (Splash Screen) of Mi A1

[GokulNC]

Note:
This is not bootanimation, this is the splash screen (the 'Mi' boot logo which is displayed when device is switched ON)
This is for Xiaomi Mi A1 Only (Snapdragon Variants)..
For other devices, please send me your splash.img so that I can create a tool for you too.

Requirements:
1. Rooted Mi A1 (any ROM)
2. Optional: Terminal Emulator app or Custom Recovery or atleast working fastboot in computer
3. You're proceeding at your own risk.


FOR NEW FIRMWARES FOR WHICH THIS TOOL DOESN'T WORK, TRY THIS NEW TOOL here:
https://forum.xda-developers.com/mi-a1/themes/tool-tissot-splash-maker-mod-5-pngs-t3799701/

Also, try these if that didn't work:

(I don't know if it works; an user seems to have successfully used it to create splash.img for new bootloader)
I never had the latest splash.img from the latest firmware, so I can't create a proper unless someone sends me

For older firmwares, proceed below:

STEPS to create splash.img:

1. Download & Extract this: Mi_A1_Splash_Maker.zip

2. Make sure you have a picture with resolution 1080x1920 or lower.
Note:
Mi A1 logo has a fixed size of 100kB allocated for splash image frame buffer, so only very light-weight pictures can 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.

3. Now rename your picture as logo.png or logo.jpg according to its format & 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:
You'll 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:View attachment 4073256 can be edited to something like this: View attachment 4073257
(Hope you understand what I say)
c. Try some other picture.

STEPS to flash splash.img:

Optional: To backup your original splash.img:

dd if=/dev/block/bootdevice/by-name/splash of=/sdcard/splash.img

(Not necessary though.. You may get it from the stock firmware itself.)

Now, Choose any one easy method to install:

a. To flash from recovery:
Transfer the flashable_splash.zip to your device and flash from TWRP or CWM or Philz or any other custom recovery.

b. To flash from Terminal Emulator:
Transfer the splash.img to your device's Internal Storage, Open Terminal Emulator & enter the following to flash it:

su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash

c. To flash from Fastboot mode:

fastboot flash splash splash.img

Note:
Incase something goes wrong or device doesn't bootup, flash the stock splash.img from custom recovery or fastboot.

Hey, @GokulNC please add options like change bootloader image, charging animations etc, and give a proper way to unpack or extract decompile splash.img file.

 

[tensaigandy]

Will this also change the 'your device bootloader has been unlocked' thingy?

 

[Stoutpuppy GFX]

Say goodbye to white

If there's enough interest I'll make a matching boot animation (Oreo flavor)

Tested and working through flashing via twrp on latest Oreo OTA
Tested and working through flashing via twrp on latest Nougat OTA

If you find yourself stuck in a twrp bootloop - look at the slot you are in
If in A choose reboot - than select slot B - then boot to system to get out of it

any way to remove bootloader unlock warning in mi a1?

 

[Stoutpuppy GFX]

need to find out how to remove or change to black

any way to remove bootloader unlock warning in mi a1?

There's already a couple of us looking into to this but so far no luck
I've combed through system dumps even and nothing to be found
If anyone knows where this screen is located please let us know

@Stoutpuppy GFX, I was reading an earlier reply of yours on this thread, did you flash the splash.img in TWRP instead of fastboot flashing it?

Any luck on anyone getting this message removed?

I tried the splash maker, didn't do anything, instead of a white background screen with the text, anytime I made a splash image and installed it, the screen was then black with the bootloader unlocked text. Has anyone unlocked their bootloader and used this Splash Maker and had it work?

fastboot erase splash works, then we get a black screen and Tux... LOL

I've always considered a Splash image what you see on a bootup, running this command removes this message, but the Fastboot image is also removed in the Mi A1.

It would be nice to not erase the splash and someone comes up with a fix for this?

Please let us know...

Thanks

No luck so far - but I read somewhere the some pixel & nexus devices have the same problem with no solution either
I'm hoping these screens will disappear once we get an official ROM for our device - fingers crossed I hate white screens

And I just flashed the splash screen through adb commands (fastboot splash splash.img) don't use brackets
but unfortunately if you have to leave your device in an unlocked state - all it will do is change the splash screen
to black with message saying your phone can't be checked bla bla - followed by that white unlocked screen shown in previous post

Please look back and read over, I edited my previous reply...

Any news about the splash solution for the tissot? Thanks.

PS: the problem seems to be the new splash format comes with the new bootloader.. Does anybody got luck to guess the format?

 

[robby_tan]

Since this tool is based on redmi note 4's tool and the redmi note 4 ones already have splash maker for newer firmware in that thread, can I use that for Mi A1 too?

The new format for RN4 is:

python bin/logo_gen.py pics/logo.png 100864
mv output.img temp/logo.img

python bin/logo_gen.py pics/fastboot.png 613888
mv output.img temp/fastboot.img

python bin/logo_gen.py pics/logo.png 101888
mv output.img temp/logo2.img

cat bin/header.img temp/logo.img temp/fastboot.img temp/logo2.img bin/destroy.img > output/splash.img
rm output\*.raw

So, I'll test it today for Tissot

Guys!!!! This format is correct!!! Have just successfully tested! :victory::victory::victory:

Just use the correct scripts I've prepared: http://anikos.su/tissot_splash_scripts_new_novicdev.zip

PS:
SPLASH - is a so-called "structured" raw image of the splash device partition.
Each bootloader parses the splash partition as a set of images created in some different media formats and sizes.
So, the new updated bootloader of Tissot is now parses the splash as a set of 4 (four) parts: "header - image - fastboot image - image 2".
