Sorry Franco just saw this! Yes you have to be careful to keep the cable pulled back when in stalling the cover and putting everything back together. If you happen to hit the handle when everything isn't buttoned up the ramp assembly will slam shut then not have any tension to open it back up hence the limp lever!
Glad you got it figured out, trust me I became a pro at it after tearing mine apart what seemed like a 1,000X lol!
