U-Mos is the only luminoth that isn't in stasis, right? The one that isn't a hologram, right? Well I opened that door already but after when you go a little in there is this barrier that has some purple cristals on it and it says that it needs to power up in order to open and when that happens my way is clear to torvus. I will try something else that's been in my mind, like using the light beam on them like we can on those pillars that also had some crystal on it. Btw when you went through to Torvus did you have the super missiles, or power bomb, or any other beam?
Edit: Nevermind, I got through it now. Afterall I just had to do how I was thinking it might be which was with the light beam. Btw, I've got the Super-Missle now.
