Guys, Citel has closed off the avenue for directly accessing software and firmware files of any kind without money changing hands. It was much different before Citel purchased MCK, but then again, it was much different before the AT&T breakup as well. I do not know of a legit source for these files. Like most things, one needs to pony up the money or do without. It would probably be less expensive to simply buy another unit on the grey market than try to fix one. I have 8 or 10 of these things sitting in my garage, and no, they are not for sale. LOL
