Ok thanks for this guys, so lets see if i got this right.
If i can use a post 2004 game to sign into live it may restore the ms dash and then i run the game (splinter cell) and load the exploited gamesave. Have i got this right and is xbox live for the original xbox still working?
As for hot swapping and chipping theyre a no go for me, so its the either the above method or ill have to just write this one off.
Thanks again for the replys, its been a while since i messed around with xboxes and i have indeed f*cked up royaly
