I'd like to do that but there comes the next problem: whenever I try to open the terminal (as discribed in https://github.com/digitalLumberjack/recalbox-os/wiki/Root-access-on-terminal-(EN)) the screen stays black and the only thing I can do is rebooting by ctrl+alt+del. I tried all possible combinations I found to open the terminal but either nothing happens or the screen just turns black.
I've saved most of the older releases and always backup my sdcard and roms. I just copied them back to the new install although the games played without them?
