Chony - you may have all the answers you needed by now - lots of great support on here. I too had a problem w/my T2 - It was my fault - I was moving a Bose Roommate speaker and it slipped from my hands and just as I caught it, the corner of the speaker smashed one of my variation buttons down inside the case. When I turned it on, I had the problem you have - never ending variation looping and no option to change it.
I took matters into my own hands....took the board apart and removed all the 25 or so screws on the motherboard. Once that was out of the way, I saw that the plastic "hinge" that held all 4 buttons had been compromised. It wasn't broken but the button that got smashed had been weakened. So I took some strapping tape and placed it across the flat part of the 4-button segment that was compromised and then carefully put it all back together. That was 2 years ago. Haven't had the problem since (knock wood).
I must admit that I had a sinking feeling in my stomach when I pulled the motherboard out. Hated to do it but I didn't want to part w/the T2 for a couple months, so I went ahead and did it. Looks like you have had the board just about to that point. If I were you I'd wait til I got a new 4-button segment to replace the one you have. The other thing you could try would be to put some tape across the button, pull it back up flush w/the surface and then use the pedal til you get it repaired.
Good luck and keep us posted!
