My friend obtained mentioned phone. He's able to install the needed files and rsap app. But the app doesn't connect. It connects for moment and then disconnects. He says that Sim diagnostics says: X CONNECT_REQ Parameeter "StatusChange" is not " Card reset"
Seems like this is the baseband issue, like in newer baseband like in nexus5.
Does anyone know if there is baseband for this phone that supports rsap?
