HELP!!!!!!!!!!!!!!

sorry if im not in the right forum section....but my xbox was recently softmodded it worked fine for a while then quit...i softmodded with the SID SPLINTER CELL GAMESAVE THING.then with evox.
like i said it worked for a while then stopped all together, Now i reloaded the origional ms dash and all but as i started backing up everything we experienced a power outtage.

in general my xbox boots past the green flubber thing then says its "XBOX LIVE IS LOOKING FOR SYSTEM UPDATES" AND THEN GO'S FURTHER SAYING "XBOX LIVE IS NOT RESPONDING. PLEASE TRY AGAIN LATER." and theres no way to get past it. I tried hooking up an ethernet cable to a router and still nothing.....

can anyone help me revive my xbox if there is a way???

 

rebuild your hdd using the hdm or hotswap tutorial. your ms dash got messed up, so you need to rebuild your ms dash. if you can boot an original game, use a post 2006 game and update the dashboard from the game!

 

ive tried using other ppls tut's but for some reason my disks never work properly....i can get to the point to where the hm looks for a partition but fails to find anything. as for #4 unlocking/locking hdd.... its all disabled....ive tried these disks many of times and not once did it work along with hotswapping ...

 

repair as for error 16 or 21.. duh!!
