I have an Xbox 360 slim, 250gb with the manufacture date of 2011-10-14. I am 99% sure it is Corona, and it has a LiteOn Drive. I was looking around for someone to flash my drive for me, and on craigslist someone wrote "---The Price for Slim Models is $40--- Note: Slims With a Manufacture Date of August 2011 or Later require a more expensive procedure, including installation of a $40 part. Inquire for details I was wondering if this guy is just ripping people off, or does it really require a $40 part to flash? Also, can someone lead me to a guide on how to flash this?
