First of all, take that activate.iso and BURN IT!

Hasn't been needed for ages now, I'm pretty sure.
Simply, the Madden 2012 disk and microsoft update are DOING THE SAME THING! They are simply trying to update your console to the latest dashboard. So it doesn't matter which way you go as long as it's updated. BUT, to update the console you have to flash the DVD drive back to stock.
Make sure you have a copy of your DVD key BEFORE flashing the DVD drive back to stock! This is important. Well, you need a copy of it anyway to flash it back to stock. Then you update your 360 with Madden 2012 or online update. Once the update is complete, then you flash your DVD drive to LT+ 2.0.
By doing the above you will be able to play your new game AND all your backups, just the way you dreamed it should be but was too scared to voice your opinion.

hello all been gone from the scene for awhile no time to play just wanting to get the kids xboxes up to speed.
I have a couple of liteons that I extracted the keys and 1 uses the iso disk on dash 9199 and another that i think i flashed with checks disabled on dash 8955. lol
Last game played was new vegas backup.
These never go online, got other boxes for that.
I stopped staying current when ap came out or the Fable 3 issues.
I just want to be current without security checks because it will never go online, is that possible.
What dash is a minimum or can I go to a hard drive or is that still for jtag boxes?
