If somebody want to replace provider/operator/or any other splash screen on Huawei device just do as follow:

Root required

First way:
  1. Install Adb and Fastboot
  2. Download this utility to ADB folder on PC
  3. By Windows CMD go to ADB folder and use this commands:
    (observe phone and make appropriate permissions if needed)
    • adb shell su -c "dd if=/dev/block/platform/hi_mci.0/by-name/oeminfo of=/sdcard/oeminfo"
    • adb pull /sdcard/oeminfo oeminfo
  4. Make copy original oeminfo file
  5. Download stock HW splash (logo) or make your own picture *.bmp. Bitmap resolution should match your device resolution (1080x1920 pixels). Put it to ADB folder.
  6. In ADB folder use commands:
    • oem_logo.exe oeminfo logo.bmp
    • adb push oeminfo /sdcard/oeminfo
    • adb shell su -c "dd if=/sdcard/oeminfo of=/dev/block/platform/hi_mci.0/by-name/oeminfo"
    • adb rm -f /sdcard/oeminfo
  7. Reboot
More options described here.

Second way:
  1. Download this (translated bye me) utility
  2. Unzip and use it

Additionally:
  • If you want to use Huawei stock splash screen you can install this file by custom recovery. It replace any splash screen you have installed by original HW.
  • Off course you can use this script to installing your own logo. Just replace file \dev\block\platform\hi_mci.0\by-name\oeminfo in downloaded zip by your own file created accordingly to above first method (by oem_logo.exe).

Are you sure? I'dont think so. At least, I was unable to find IMEI there. And it would be too easy to change IMEI if it could be in oeminfo partition...

hi Kostyan_nsk and z!log80 !
I have recently flashed oeminfo.img without isssues (thanks again Kostyan_nsk)
I wanted to give it a try and ask please Kostyan_nsk or z!log80 for a brief explanation about how oem_logo.exe performs the bitmap replacement. Is it possible to mount oeminfo.img browse its file system and replace a particular file, or is it by searching bitmap signature, …?
Thanks Ziolek67 for starting this thread :laugh:

yes, same as before
if no file system or mount then I guest search for a pattern or dedicated tool to package... I have been trying to find further more precise information about oeminfo.img but had not found much so far. I would appreciate if you can contribute to make this a bit clearer for me
thanks
[Edited]
After a bit of research I have found other mods for factory device location, etc. writing to particular offsets, tools to modify, backup and restore oeminfo.img. It is a data store. No embedded code. Thnx!

I flashed whole oeminfo partition from other device and my IMEI stayed the same. As I supposed, it's somewhere else, but not in oeminfo partition. You are wrong.

Do not worry, I also used HW-OEM_LOGO.ZIP to change the booting logo for the original one, and my IMEI is the same as I bought it in the store, so do not be alarmed !!!!:laugh:
