X360 software help needed

I was given an x360 with RRoD, I fixed that but now everytime I turn on the console it loads to just past the start-up screento a black/grey screen that reads ''Update failed'' ''Could not find your xbox 360 hard drive'' I have tried with the HDD on and off and the same message. I found out that the system will not update unless the exact same update that is currently on the console is re-loaded. Does anyone know where I could find a list ofGames that have system updates and which version? The update I'm looking for is 2.0.7363.0 any advicecould help. I've tried to update the console with GTA4 and Gears of war 2 and both failed the update and gave the same message. :cry:X360 software help needed
Go to google type in something like ''xbox 360 archived updates'' and maybe even the update you're looking for. Find said update and burn to disk. That will probably work.I googled that and the first thing I saw was people that had updates to burn to disk.
