[GUIDE][Redmi 4 Pro/Prime] How to Change Boot Logo (Splash Screen)

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 Redmi 4 Pro/Prime Only (which has 1080x1920 resolution)..
For Redmi 4 or 4A, please send your device's splash.img as given in link below.
(For other devices, please send me your splash.img so that I can create a tool for you too.)
Requirements:
1. Rooted Redmi 4 Pro/Prime (any ROM)
2. Optional: Terminal Emulator app or Custom Recovery or atleast working fastboot in computer
3. You're proceeding at your own risk.
STEPS to create splash.img:
1. Download & Extract this in computer: Redmi_4_Prime_Pro_Splash_Maker.zip
2. Make sure you have a picture with resolution 1080x1920px.
3. Now copy your picture inside "pics" folder and rename your picture as logo.png or logo.jpg (according to its format).
4. Finally, run the 'CREATE_LOGO.bat' to create splash.img and flashable zip file, which you can find inside the "output" folder after completion.
STEPS to flash splash.img:
Optional: To backup your original splash.img:
Code:
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:
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:
Code:
su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash
c. To flash from Fastboot mode:
Code:
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.

You're welcome to post the splash images that you created..

Nice. Do I need re-flash everytime I change rom?
And where can I find stock splash.img in my device?

Works great!
(I put a personal picture, so I prefer not upload an example, but it came out great).
I never dreamed that suddenly pop up an official guide for my model,
And certainly i never dreamed that the credit I deserve.
All credit goes to you!
Thank you very much! :good:

nice !

I'm try this guide on my redmi 4 prime… but why the end bootsplash no change…?? Still mi.com…

I followed the steps carefully, i'll say that this works like charm!

um... How do you think it would apply to redmi note4x?

Assuming yes to both, as this is before we get to system startup, but:
1) this will work regardless of rom?
2) this will work on encrypted phone?

Thanks a lot dear! Very useful!

Built custom splash screen and flashed on stock rom, it worked fine. Dirty flashing Epic ROM didn't replaced splash screen, can't say about fastboot flash.

How do I extract the .png/jpg image from stock splash.img ?

You may try Android Image Kitchen. Both pc and Android version are available on XDA.

Thanks for the great tool! It worked great on my device.
I made some Google Logo Spalsh images, the original images were extracted from here, and I made some changes with PS.
Hope you guys would like it

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

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:

https://forum.xda-developers.com/mi...change-boot-logo-splash-t3681033/post75978168
(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:
Code:
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:
Code:
su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash
c. To flash from Fastboot mode:
Code:
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.

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

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

@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

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?

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?

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".

[MOD][SPLASH][OP5t] Splash Screen Image Injector

This is a program that I wrote to decode and re-encode the OnePlus 5T "logo.bin" file. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've found this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel horizontal line in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 133 /// we've reached the top left corner of the red line /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red line the encoding was decoding to 255 zeros over and over, until finally 133 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is ONLY good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(243, 243, 243) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.​
The attachment contains the executable that was compiled using mingw32 on a 64 bit Windows 10 PC. The PNG library that I used is LodePng, the source is in the download.
Big thanks to @RajGopi for sharing his logo.bin with me and requesting this mod, and testing it as well!:good:
To use the OnePlus 5T Logo Injector:
Decode your logo.bin:
Code:
OP5tLogo -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNG(s) that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or a different style, then the program will tell you and exit.​
Inject the image(s) back in to the logo.bin:
Code:
OP5tLogo -i logo.bin -j fhd_oppo fhd_at
To list whats in your logo file:
Code:
OP5tLogo -i logo.bin -l
For a more detailed list:
Code:
OP5tLogo -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
OP5tLogo -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
OP5tLogo -i logo.bin -j image_name -s
Note:
You can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though​
The size of your modified.logo.bin will displayed along with the original size, if everything went good. The 'splash' partition is 16 MB on the OnePlus 5T. If you use too much color on too many of the images you will easily go over 16 MB. The program will tell you and delete the "modified.logo.bin" that was created. If for some strange reason you would like to keep it, use the "-B" flag on the command.
The last step is to flash the modified logo file via fastboot with the command
Code:
fastboot flash LOGO modified.logo.bin
Use this at your own risk.
Always make backups.
Always.

Please forgive my ignorance. I think I got everything done properly. I just don't know what you mean by the above statement.
Normally, if I flash a new recovery in fastboot, I use the phrase fastboot flash recovery xxxx.img

Thanks,

P.S. Where on my OP5T is the original logo.bin file located?
P.P.S. I believe I found my logo.bin file; however, it appears I made some kind of mistake and now I simply have a black splash screen, and nothing I do gets the default splash screen back, including Nandroid restore. It always remains black. Does anyone have an original OP5T logo.bin file they can give me to download? Also, the file I found is called LOGO, not logo.bin. It's in the following directory:
/dev/block/bootdevice/by-name/
P.P.S. I also believe I found the right command in fastboot. Is this the command to flash the logo.bin file:

Thanks for the question, but 49 out of 50 times I do not have the device that I am working with. When you use fastboot program, you flash `x` partition with `y` file.
It doesn't matter what `y` is, but `x` is the name of the particular partition that is case sensitive. You can rename `y` whatever you want. It is hard to find partition dumps or names, so I can not worry about what the actual partition name is for a particular device. I could of asked @RajGopi when he tested, but I did not. With nearing 9 million people on XDA, I will gladly let people do their own research or what not before flashing anything for unsaid reasons which others will understand unsaid. In the past I have guided people to this thread. But thank you for wanting more clarification on the actual command with fastboot, I will include it in the post since this program is made specifically for the OP5t.

Argh! While your zip file worked perfectly, I'm now trying to modify the PNG file. I got everything done correctly (I think), but when I flash it, I still have your logo, not mine. Obviously there's something I'm doing wrong. Is there anything special about the PNG file? When I copy the modified logo.bin file back to the ZIP file, do I use standard compression or no compression?
Any ideas?
Peter
P.S. I'm trying to get the following PNG file as my Splash Boot image. If someone could create a flashable zip, that would be great, but I still would like to know what I did wrong. I want to learn how to do it, as I did with my OnePlus5.

I hope you are renaming the output file to logo.bin and replacing it in the zip
- Check for image resolution
- Normal/standard compression will do fine

Yes, I renamed it to logo.bin, and I tried both normal/standard compression and no compression, but it's not working. Your splash continues to display.
What about the image itself? Must it be 256 colour gammut? I'm also assuming that it has to be a PNG file.
Peter
P.S. I even tried flashing the new zip AND by the fastboot method: fastboot flash LOGO logo.bin

I'll give you flashable zip tomorrow with the image you provided.
Yes, it must be a PNG

Thank you. In the meantime, I'm going to try and figure out what's going wrong. I simply can't let this go. I have to solve the problem.

Peter
P.S. I figured it out. I had to modify the encoding command to make it all work.
Was using: OP5tLogo -i logo.bin -j fhd_oppo fhd_at
Changed to: OP5tLogo -i logo.bin -j fhd_plus_oppo fhd_plus_at
Now everything is working perfectly. Thank you for your assistance.

Hi, I'm interested in doing this, but I never edited my bootlogo, any help on how to get the logo.bin from my phone?

Sorry, I meant there's instructions there on how to extract your logo.bin, use the tool from here to extract and inject images with your dumpling logo.bin

I'm preparing a detailed Guide on how to prepare and implement a custom boot splash. I should have it ready for download within the hour.

Okay, as mentioned in my previous post, below is a detailed Guide on how to create your own custom boot splash for the OnePlus5T.
Download the PDF file here: https://www.dropbox.com/s/t45ld1abip5orhv/OnePlus5T Custom Boot Splash.pdf?dl=1

[GUIDE] How to Change Boot Logo (Splash Screen) of Razer Phone (cheryl)

Note:
This is not bootanimation, this is the splash screen (the boot logo which is displayed when device is switched ON)
This is for Razer Phone Only.. (codename: cheryl)
(For other devices, please send me your splash.img so that I can create a tool for you too..)
Requirements:
1. Rooted Razer Phone (any ROM)
2. Optional: Terminal Emulator app or Custom Recovery or atleast working fastboot in computer
3. You're proceeding at your own risk.
STEPS to create splash.img:
1. Download & Extract this in computer: Razer_Phone_Cheryl_Splash_Maker.zip
2. Make sure you have a picture with resolution 1440x2560px.
Now rename your picture as logo.png or logo.jpg (according to its format) & replace it inside "pics" folder of the extracted folder.
3. Finally, run the 'CREATE_LOGO.bat' to create splash.img and flashable zip file, which you can find inside the "output" folder after completion.
STEPS to flash splash.img:
Optional: To backup your original splash.img:
Code:
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:
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:
Code:
su
dd if=/sdcard/splash.img of=/dev/block/bootdevice/by-name/splash
c. To flash from Fastboot mode:
Code:
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.

You're welcome to post the splash images that you created..

You can just change the boot animation.zip located in system /media and set permissions to rw-r-r.
Here I renamed the original to stk-bootanimation.zip then added what I wanted.

Splash screen is different from boot animation. The one which appears before boot animation

Oops sorry, brain fart.
I guess I wasn't paying attention all that well.

@GokulNC, does this also disable the Qualcomm verified boot/5 seconds to boot message? And if not, is there any possibility to do so?

I would guess the splash screen is reading the bootloader state from somewhere so if that's the case disabling it or at least hiding the message might be possible since the image can be changed

Nope, the splash screen is just a BMP picture (in RGB24 format) with an empty 16kB header before the picture.
You could see that in the batch file's code.

The warning message actually is from the bootloader itself.
Most probably, it will be present in the 'aboot' partition, but it's not as easy as changing splash screen.
The same issue was also present in Nextbit Robin. (a company acquired by Razer)
Because, the bootloader is just a raw file when dumped, which needs to be checked using hex editor or whatever tool to see if it has an image and find its offset and patch the image accordingly, or even, it might be possible to find the location of where the amount of warning time is present and make it 0.
But the problem is, since it's a raw dump and the bootloader is the code that brings up the kernel, it's highly possible that if we do something wrong, the device might be hard-bricked (even fastboot mode is from bootloader). Also, today's bootloaders might even be signed, so patching the bootloader for warning picture might not necessarily work since the device won't be able to verify the integrity of bootloader partition after its contents change.
So, if there's a tool with which you can flash and recover a hard-bricked phone, and if you're willing to test the modified bootloaders that I create, send me the bootloader partition dump. I'll take a look at it

@GokulNC, thanks for your highly detailed explanation, but I'm not taking the risk of having an 800 USD brick :)

Lol I remember doing stuff with my Droid RAZR and Bionic for dhacker back in the day. It was worth it in the end, but took time for the recover from hard brick processes to come about.

Hi, can you please upload and share the default bootanimation here? I have deleted mine and would like to get it back.
