I'm trying to change to splash-screen / boot logo of my Sony Xperia Z4 tablet (SGP771)
I have already rooted my device.
With the help of the bootimg.exe tool I unpacked the boot.img - exchanged the logo.rle and repacked the boot.img.
My custom logo.rle I created with boot_screen_logo_creation_package.
However, when flashing the new-boot.img to my device (with fastboot flash boot new-boot.img) the logo is not changed. Still showing the Sony logo before the bootanimation appears.
My tablet runs the Marshmallow firmware and I'm using the corresponding AndroPlusKernel v31 (Z4T_SGP771_AndroPlusKernel_v31.zip).
I tried already different tools like bootimg_tools from this xda forum, or split_bootimg.pl from the android-wiki.
The one mentioned in my question I found in several forums (wordpress, miui, dark-cyanide-devs ...)
Most of the tools I tried already did not repack the image correctly (fastboot reported "remote: dtb not found")
The tool I used, mentioned in the question, seemed to work for correcly unpacking and repacking. But as I said - the logo does not change -.-
Any suggestions what I am doing wrong?
