Installing screen drivers

[MoDDiB]

Hello,
I've bought a 3.5inch screen for my raspberry but it stays white under recalbox.
I have to install the drivers with the tutorial here ( http://www.waveshare.com/wiki/3.5inch_RPi_LCD_(A) ) but raspi-config doesn't work.
Does someone know how to install this drivers ?

Thank you

From what I read inside the archive you're supposed to download, you need to extract the right dtb, modify cmdline.txt and config.txt. You also need a new inittab but I can't see what changed
