Yeah i havent got it either yet. Every time i start a run it just seems so stresfull to rush the game and knowing every little mistake could cost you the trophy

Yes, but you could use cloud/usb to backup your run. Backup your save at every end of a chapter of your no death run and if you mess up, you could download your save and continue it that way.

Did you start a new game, or use chapter select to start the run? To my undestanding you need to start a new game to be able achieve this trophy

I have not played the vita version, but i think you need the box breaker gadget from planet Oozla after you obtain the gravity boots.
