Right heres my story , my previous xbox has open tray error so i sent it for repair , waited 3 weeks got an email saying a replacment console is on the way your old console could not be repaired , wait another week for the console to arrive , it arrives today i am so happy i turn it on it does some tut thing tells me to update ( i had my old hdd in with the update already on ) its updating i come back and e81 error no red arrows come on just pure red in the middle .

I have tried a different hdd no help , a different hdmi lead no help , a different plug no help , unplugged everything and turned it on no help the console will not even boot , i press the power button its green for 1 second then turns red shows me e81 @~

after waiting 4 weeks for a new console i am angry i don't no what to do i can send it back for repair but i don't want to i no theres got to be some sort of fix for it somewhere even temp fix , i was looking forward to playing onslaught for ghosts but xbox shit on my head theres nothing on the internet for it i am lost right now and unhappy

Help please
