A "Total" factory reset?

Hi all

My MBL had really got its knickers in a twist… i want to install Serviio and have done successfully in the past… however MBL now reports various errors so I have tried various methods to reset it…

I have done the button reset, used ssh and Putty to force a reset etc… these are all well and good but they don’t seem to work… for example my sources.list file remains the same and the previously Serviio folder still exist.  I want a factory reset that wipes absolutely everything so that I am starting with an “out the box” drive…

Any suggestions please?

This script works for me everytime to restore back to factory firmware and settings
