I have tried, tirelessly to put os 7.0.0.439 on my 9900 but it just wont work. I'm not a rookie at this as I've updated many berries in the past. I have deleted the vendor file as per usual, but still as I try to use the app loader to load the OS, the only thing that pops up are the apps when the whole OS should be there. Then you can check and uncheck everything you want loaded.
I've tried it on 3 different computers as well. There is no other previous OS's on these computers, no lurking vendor files...it just won't work.
Please, if anyone can help, id sincerely appreciate it.
