Run BIOS checker to see what your current BIOS is, then you can make an informed decision about whether it's worth upgrading or not, rather than just guessing.....
IGR (left trigger + right trigger + back + black) is a BIOS function, so knowing your BIOS version might help answer your new question....

I've never used an Aladdin, but all but one of my Xboxes have one of the BIOSes I suggested, and they all reset to my preferred dash, not to the MS-dash.
