26 / 5.000 Update to 1.0 from script

As I say in the title, I read that someone was working on a method to update to version 1.0 etc using a script instead of USB, I ask this because I have tried many times to update via USB drive following the step by step guide and trying Ubuntu, Kubuntu, Ubuntu Server, Debian, but without success… I have a PC i5 2400 / 16GB / 2TB RAM.
