Update from 8104 to 8107 or later

[NairobiWP]

Hey there Lumia 900 owners.

Did any of you remember whether your Lumia 900 was shipped to you with a 8104 ROM? And if yes, how did you upgrade to 8107? Was this included in the ROM update released by Nokia in April/May?

I have a friend who has a Lumia 900 that has 8104 and he cant update it to 8107 using the WP7 Cab sender process. He keeps getting a 8018004d error.

Thank you.
