Hey, Problem, Deus Ex: Human revolution doesn't allow me to play (I installed on the HDD) because it asks for an update. I'm on 2.0.9199.0 Dashboard, and I have a Lite-on DVD drive, I believe 1.1 or 1.7LT flashed (the one that ignores waves). I can only tell you the last major game release I had no problem with was Two worlds 2, released on November 2010, PAL. The next game was this one released like 2 days ago and it doesn't work. Gives me an update request. Updating from the DISC questions 1) Is it safe to update if one day I want to get a mod-shop to install LT 2.0+ in the future ? Something to do with extracting the keys problem. 2) Will it still allow me to play FABLE 3 and HALO Reach after the dashboard update backed up and original ? 3) Will it allow me to play non-ap25 games ? Ergo all my original and backed up disks ? Thank you. I DO NOT care for ONLINE/LIVE. My console is STRICTLY offline. I have never taken it online ONCE.
