A trinity slim, xbox live banned console working perfectly prior to opening it up.
Coolrunner Install went perfect, flashed nand with j-runner. glitches within 10 seconds with no dvd/hdd installed.
however once i connect either/both it returns a E64 error. unlocked the dvd, still the same.
I've flashed back to the original nand and it does the same. removed coolrunner completely still the same.
I could really could do with some help on this one!
