I've just brought a new 360 to replace my banned one, liteon 7xxxx
Should have read this thread 1st, as I flashed it with 1.6 with ck3 for power and went online for some MW2 original.
1 hour in and I was disconnected from live, tried to reconnect and was told I was banned.
This Console was brand new and never had a backup in it, online for no more than an hour playing original of MW2 and got banned.
To me this is obvious that they're detecting the firmware.
I'm not bitching as it was my choice to mod the firmware, well done M$. M$ 2 BM 0.
At least now I have my brother Chrimbo present sorted.
