Changing Boot logo on Android

Post by Argentum_90 »

Hello, I am a bit lost in this proccess following instructions on the Wiki.

1. VFAT
Copy the new boot-logo.bmp (or boot-logo.bmp.gz) to VFAT partition.


How can I access to the VFAT partition?

2. Android Logo Partition
If you want to replace the logo data in logo partition, please follow this guide.
First, you must get into your U-Boot command line while pressing the ENTER key when your ODROID-N2 is powered up.
And execute fastboot command from U-Boot and connect it with your desktop using a USB cable.


I press ENTER when the Odroid boots but nothing happen. It keeps starting Android.
How can I connect the Odroid to a PC with a USB cable? Is it like SSH?

Thank you in advance guys

It will be the visible partition if you connect the media to a Windows PC.

I have changed both logo and animation on Odroid N2 and it is quite easy. Assuming you have pushed the gzipped logo/animation file to sdcard or any other location (change path in command as required). Run the following commands:

// ****** To change logo *******
mount -o remount,rw /odm
cp /sdcard/boot-logo.bmp.gz /odm/
chmod 755 /odm/boot-logo.bmp.gz

// ****** To change boot animation *******
mount -o remount,rw /system
cp /sdcard/bootanimation.zip /system/media/
chmod 755 /system/media/bootanimation.zip

I could copy the boot-logo.bmp.gz in the VFAT partition in my Windows PC, previously I had changed permissions to 755 in the file.
If I use chmod 755 /odm/boot-logo.bmp.gz, I get an error message. I think this is because I am not root?

Anyway, when I boot the N2, now the boot logo screen is dark grey, now I have not the Harkdernel logo, and not my logo, just dark grey screen.

Any ideas about what am I doing wrong?

No, because VFAT partition does not support permissions. Check for right image format.

I have had some improvements. But I notice one problem. The logo shows less than a second and later I get a gray screen of 2 seconds before the boot animation. Is any possibility of make longer the boot logo instead of the gray screen? Here you have my boot sequence:

If you want to display logo image, the kernel must draw logo too like u-boot doing.
