[Honor 5X Themes, Apps and Mods] metpolds:
Tired of looking at that honor 5X standard boot logo? Well here are 8 different ones I've made for you to chose from. This has been a bit of a challenge due to the different and occasionally strange 5X OS. I must thank @deadman96385 for pointing me in the right direction to where the 5X has it's boot logo stored.

Before using you must be aware that it is possible to soft brick your device, however I have changed my own boot logo 8 times using each one of the posted examples successfully.

At this point I must emphasise that I am not responsible for any ills that may befall your device, including soft and hard bricking through to Aliens landing, mating with your dog and then trashing all your devices.

It is not possible to upload .mbn files to XDA, therefore I have renamed the file extensions to .img, AS SOON AS YOU DOWNLOAD THE FILE rename the extension to .mbn

UPDATED 2/23/2016

I've had a request to give a guide for creating the oemlogo.mbn files to complement what I posted in respect of installing new boot logos. To keep it in logical order I have done a rewrite of the first guide and put in the new points at the appropriate places. If you are not bothered about making your own .mbn files but instead are just happy to use ones that I or anyone else post then you can just pick up at the appropriate point in the install part of the guide.

To create .mbn files for the honor 5X you will need the following..... (1) A graphics manipulation program - the one I use is the free "Paint.net" which can be downloaded from their web site at http://www.getpaint.net/index.html..... (2) You will also need a program which can remove the 54 byte header from .BMP files. Those of you proficient in code/scripting can probably do this with a good hex editor but I needed to find a program to do it for me. I use "bmp-header-remover.exe" from here http://karpolan.com/software/bmp-header-remover/ .... to be honest there is a lot of dispute and controversy on the Web about this type of program so I won't tell you to use it but for what I wanted it did the job.

When you get to the installation stage you will need on your 5X a File Manager and a Terminal Emulator.

OK let's get started ....

1) Firstly you have to find an image you want to use, this can be any of these .JPG, .PNG, or .BMP, personally I prefer to work with .JPG's. Bear in mind that the 5X default image size is 1080 x 1920 so if you start with a small image let's say 300 x 300, by the time it has been blown up to the full 5X size you are going to lose some definition and you will likely get an unwelcome degree of distortion.

2) Open the "Paint.net" program and click on the heading "Layers" then on the drop down menu click on "Import from File" then in the window that opens, navigate to where your image is and click on it to open it in "Paint.net". Don't be disturbed by the size or appearance.

3) Click on the heading "Image" then on the drop down menu click on "Resize". In the "Resize" window that opens enter the size of 1080 in the width box and 1920 in the height box. Then click "Ok". Your image will now be resized to the 5X parameters.

4) At this point you can use the "Paint.net" tools to adjust colors or add text and if you experiment you should be able to stretch or contract the image to how you want it. I make no apology for the fact that I am not giving a guide to the use of "Paint.net" here (their help page should answer any questions you have).

5) Now comes the juggling bit. In "Paint.net" click on the heading "Image", a drop down menu opens so click on the choice "Flip Vertical". Your image now takes what I think of as an "upside down and inside out" aspect, you'll see that it's upside down and in effect is a mirror image.

6) Now you need to save the file. Click on the heading "File" and from the drop down menu click on "SaveAs". Now it is important to save the image as a .BMP file irrespective of whether you started with a .JPG or .PNG or .BMP original. In the "SaveAs" box "Paint.net" tends to default as its own file format(.PDN) so change this by selecting .BMP. At this time you can leave the filename as it is or change it, it doesn't matter. Make certain that it is being saved to the folder location you want then click "Save". The next screen you get is the "SaveConfiguration" window, on the left hand side of this window you must click on "24-bit", leave everything else alone and click on "OK". Exit out of "Paint.net".

7) Now you need to run the program "bmp-header-remover.exe". A small window opens up and you will see two empty slots (to be honest you only have to read the screen and you will see what you have to do). In the top slot enter the path to your newly created .BMP file - In the bottom slot enter the path and name that you chose for your modified file. ***VERY IMPORTANT - YOU MUST GIVE THE FILE NAME AN .MBN EXTENSION*** So just to emphasize in the top slot you will have a .BMP file and in the bottom slot you will have an .MBN file. Click on the button "Remove BMP Header" and you have successfully created your .MBN file.

Now we move on to the "INSTALLATION" phase

8) Transfer the .MBN file to your device putting it in whichever folder of your SD Card you prefer. Use your File Manager to copy or Move the .MBN file to the Internal folder...../cust/hw/usa/logo..... If you want to keep the standard boot logo (as a safety precaution), rename it now or it will be overwritten. Rename your new .MBN file to oemlogo.mbn and change the permissions to match the original.

9) Come out of File Manager and open your Terminal Emulator. At the $ prompt change into superuser mode by typing su and pressing Return/Enter. You will then get the # prompt.Type load_oemlogo press Return/Enter and several lines of text will display, when this stops exit out of Terminal Emulator.

10) REBOOT and enjoy your new boot logo.

I have posted .jpg's so that you can see what you are getting.
