Im having a somewhat similar problem with gta SA. I own a korean modded xbox with evox +3935 and the current dash is :1.00.5960.01 and kernal 1.00.4817.01 . I own the retail version (version 2 w/o the hot coffee) of GTA SA. The game used to run fine either on my hdd or direct off the disc. I went onto xbox live (to download those new halo 2 maps, and I used one of those free 2month subscription cards). When I went online I updated my xbox via xbox live. I poured over the internet checking if xbox live would srew up my xbox, I could not find any documentation saying not to do it. Of coarse I updated and reset my xbox. After that I could not play either GTA SA, Star Wars KOTR, my xbox states "Region Error". It doesnt work through exox either, the screen fades out like its loading then fades back in like it was rejected. If I play it off the hdd it freezes at the evox loading screen. The weird thing, I can play most of the other games I have either on HDD or disc (Half Life:2, Halo 2, Gun, DOOM 3 collectors, brothers in arms)either through exox or M$ dash. What should I do I went to a gamestop the told me they can be fired for talking about modded consoles which is rediculous since the supreme court ruled modchips and modded consoles legal. Should I upgrade evox or downgrade my M$ dash does any one know excatly what I can do? PS: Im not sure what modchip I have but i do have samsung dvd drive and 120 gig hdd. PS how exactly do you upgrade evox, I know how to ftp and transfer files but cant figue out how to upgrade the evox dash.
