Hacking Black screen when loading a backup (Flashed XB360)

[rave43]

Recently burnt a backup from a friends GTA San Andreas and want to play it on my flashed Xbox 360.
I've patched it successfully with abgx360, however upon booting/loading it on my 360, it goes to a black screen and freezes. I've checked Xval and i'm not flagged.

Was wondering if anyone had any pointers? is there a chance that it could be the ISO, I haven't got the tools anymore so won't be able to reflash or access any logs unfortunately.

Thanks in advance

Mulleted ISO or untouched ISO?

It's been a long time since I done anything original xbox related on flashed 360 and I remember something about LT firmwares not supporting it anymore.
Could be wrong on that tho.

I managed to solve it.
Basically my Samsung drive was flashed to the LT version that can only run pre- AP25 games. I tried another, older game and it worked fine.

I think the latest is lt 3 0.
