[Tutorial] Edit your Note 4's Boot Splash Screen!

I've tried to find a tutorial for this, but seems like it doesn't exists. So I've learned about S6, Note 5 and even a russian Note 3 Neo tutorials to make it work. So let's start!
What do you need?
-Patience
-A PC with a Photo Editor (Paint.net should do the trick)
-Terminal Emulator with a little of practice
-(Optional) an external keyboard, since you have to execute quite a lot of commands and there's no way to copy paste into a terminal like in CMD.

1)We start by pulling "param.bin" file out:
It's located in /dev/block/mmcblk0p8 so we have to execute these commands:

Code:

---

su
dd if=/dev/block/mmcblk0p8 of=/mnt/sdcard/param.bin bs=4096

---

2) This will extract param.bin to your main sdcard folder, then we have to create a new folder and then untar it, by executing this:

Code:

---

mkdir /sdcard/param
cd /sdcard/param
tar xf /sdcard/param.bin

---

3) If everything went fine, you should see a folder called "param" with all the bootloader's images. We will focus on logo.jpg, but you can change the others like download.jpg and warning.jpg. Extract these files to your PC and edit them, make sure that the images doesn't go up to 400 kb, otherwise they will not show in the device. To achive this you can downgrade the JPEG quality from 100% to 80% or any % you feel confortable to use. Once you finish the editing process, place them inside your main /sdcard folder.

4)Now we have to paste your edited images inside /sdcard/param folder and retar param.bin, we have to execute these commands:

Code:

---

cp -f /sdcard/logo.jpg /sdcard/param/logo.jpg
(OPTIONAL) cp -f /sdcard/warning.jpg /sdcard/param/warning.jpg
(OPTIONAL) cp -f /sdcard/download.jpg /sdcard/param/download.jpg
rm -f /sdcard/param.bin
cd sdcard/param
tar cf - `ls | sort -t.` > /sdcard/param.bin

---

5) Last but not least, we have to place param.bin back again in the system, so:

Code:

---

dd if=/sdcard/param.bin of=/dev/block/mmcblk0p8 bs=4096

---

If everything went fine, reboot and you will see the new logos come up! Make sure to backup param.bin once it gets extracted, in case if something goes wrong. There's no way to brick the device, the major risk is a blackscreen while booting, but the device will boot fine so you can repair it without problem (IF you made a backup, otherwise you will have to reflash the bootloader in ODIN).
I hope you like it! Leave your questions below and I'll try to answer them ASAP. Cheers!
