So after seeing that 7.1 dropped, I purchased a 9900. I downloaded 188.8.131.52. I couldn't get it to load. I saw on the 9810 thread that .540 was needed before you could load 7.1. I downloaded 540, installed it. However, I still can't get 7.1 to install...
Here is what I am doing:
Add remove programs, and remove all installed versions
install 7.1 on the pc
plug in bb 9900
The only option that comes up is to install wireless music sync.
Without 7.1, I can't use this phone as I depend on wifi calling at my location.
