there was no update to the console after the server upgrade. the software update wont come until later this fall.
after running debug software on my drive along with other people in the firmware modding scene, no one picked up any changes to the challenge/responses that the drive is tested on.
also, the problems are mostly not caused by the new firmware. anyone using a hacked drive online should be using iXtreme 1.2c, not anything in the Xtreme or before. You do run the risk of getting banned since each release is in response to a new check that MS sends out.
