I will make an official post soon but I hear that Kospet will firstly release a hybrid firmware as an OTA. V2.0.
It is a mixture of the custom firmware and the original firmware.
However, it is not possible to use Google the same way as the international firmware we worked on with Wiitee.
But, they will follow up with the international firmware we have posted here as an OTA in a few weeks time.
We will post the latest version of the Prime 2 international FAW firmware in the next few weeks.
To be able to receive the OTA you need to flash back to a stock version like 1.4 first.
I will make sure that it is available any way.
