overwritten eeprom

my friend accidentally overwrote my brand new xbox's eeprom while switching an HDD from my old xbox to my new one. What do i do??????? can someone please help

 

there r tools u can use to fix that stuff. use google itll help u most i think

 

i dont think that you understand... it doesnt work now at all

 

if you xbox still still turns on than it still works a little bit. if you power on, put in a game reset with game still in will the game boot. if so than you can use a mod chip to fix it. thats all i know of. if its not a 1.6 than u can TSOP but you said u just got it so its probably a 1.6.
