I was modding my friend's xbox 360 today and i must have done a bad flash because when i plugged it into the tv i get system error E65. I've modded mine fine with no problems and he has the same drive as I do, but with his i am running into loads of problems. I have a disk made in iPrep with the orig.bin to flash it back to make it stock again and it won't flash it. I do the bad flash recovery 10 second trick and everytime it just hangs on Port: f8e0, Master/Slave: a0. I know I must have had it right some how because i have the original firmware, but some how i just can't seem to flash it back onto his drive. Please help, I let him have mine until i can fix his, so i need this fixed. any help is appreciated. Thanks!
