Motorola XPR 7550e firmware update, please help


I need to update the firmware on my xpr7550e, where can I download the latest one? Any help will be appreciated.

Thank you!

P. S. I got the password from the man who sold it to me, very nice guy, has been looking for the former employees of the store that used to service it. Once I update it I’ll be very happy! Assuming I can.
