anyone tell me this build (10166) call and sms work correctly? because i want to install this biuld in my primary phone (lumia 930).
It should but you never know before you try. Some people "lost" the data connection. So it's up to you and you should know it is not advices by MS to use it on your primary device.
But first download and check the WPRT because that's your only way back. And during the download and update be sure your battery is fully loaded and keep your phone on the charger. Furthermore get your phone out a case to prevent "overheating".
Good luck and "Don't do the crime if you can not di the time".
