OK I have the Aladdin chip installed and everything boots up fine but it still boots to the original Xbox screen what do I need to do now that I have the chip installed

Hello, long-time Xbox user here, and you may recognize my username from many other forums.  I softmodded my console ages ago using SID 5.1.2.  Recently I wanted to try it out on Xlink Kai, but I couldn't join any games in Halo or Halo 2.  When I launch Halo, I get an orange ring for 15 seconds before the menu arrives.  My profile is no longer there.  Halo 2 tells me the DLC is damaged.  Strange.  So based on a few guys in the Xlink lobby suggestion, I went and used Rocky5's soft mod Quick Upgrade, which seemed to work.  I had to fix a few things to restore the UnleashX dashboard skin I was using before.  Anyway, I'm still having the same issues with the Halo games. 
1. First question, why would I be unable to join System Link rooms?  I verified Xlink can see my console fine.  I even tried to create a game but was told I appear to be "offline."
2. I'm wondering if the Game Saves are screwed up and causing the issues, but I don't know of any good Save Managers to try.  I attempted to open the MS Dashboard, but I get a Service Error page.  
3. The system is hooked up to a CRT in 480i, so I cannot load XBMC or XBMC4Gamers because they seem to be defaulting to 720p, and the picture is a scrambled mess.  How can I change that?
Thanks!

Looking for help with my modded Xbox. I had this done by someone (can’t remember who) back in 2005/2006 and I haven’t started it up in over 5 years. I have tried a lot of button combos and it won’t boot up. It won’t even boot up in regular mode either. No matter what I do it turns on then Immediately shuts back off. It is a Halo edition with the X3 and control panel like the one pictured above. Any help would be appreciated. Also looking for recommendations for someone that could repair it if necessary.
