Just wanted to put a note out to the users...
On a 4034 xbox, with a hyundai TSOP, when flashed (4978, 4978 fixed, or any of nghtshd's hacks) the box defrags.
Symptons are: No video.
Green led stays normal, and flashes normal sequence as if bios was totally cool. Box doesnt ping/connect, so im assuming that there is nothing going on that i cannot see (i thought perhaps it was just a video confliction, and that it was really booting in the background)
The flash was definitly good, as i reflashed 4976.02 after testing multiple flashes of the listed bios's above, and it booted normal as should.
So the moral of the story is, if you have a 4034 hyundai TSOP and your doing a flash....dont =p
