Have changed the annoying bootloader warning logos, the annoying triangles, but take care to know the things combo keys to be hold-released ...

The magic is in the dev block sda5 and it's tar balled with 8 MB trailing size.

Have prepared the ustar tar ball with trailing zeroes ...

Feel free to do anything with it ...

Add trailing zeroes to 8 MB and replace the block.

SDA5 (original, patched)

You must be rooted to replace original file ...

After replacement feel free to reboot ...

Feel free to press -Thank you
