No, you should not rename the files. Within this thread, if you read it, it does not matter.
Yes it will reset on eject, this was pointed out at the beginning of this thread, please read it in its entirety. To get around the reset on eject, the dvd tray must be open before pressing A on the xbox live tab, and once evox or whatever dash you put on loads, you may then close the tray. It clearly states the tray must be open before going to "xbox live" in my readme (atleast I thought so, sorry if I was confusing). As for the old dash loading, did you place a 'evoxdash.xbe' named xbe in the root of your C drive? You did not specify if after the old 4034 dash executed a xbe loaded.
P.S. I am using the Halo SE Xbox also.
