The command he wrote was this:
sudo perl -pi.bak -e 's;\xff\xff\xff\xbf\xbf\xbf;\xff\xff\xff\x00\x00\x00;g' bootI understand that with this command, basically I change all the three 191(grey) colordata to 0(black).
My question is, this should really work? I searched the internet many-many times for this background color thing, and never ever found anything, and everyone said that it's not possible to change the background color of the bootscreen. So, it is really that easy to change the background color?
I wanted to ask before I try this, because I don't know how to recover my "boot" file if it gets broken.
