As stated in the news section of this website (accessible here: Non-supported phones will see Windows 10 Mobile build 10536, but you shouldn't install it | Windows Central) you shouldnt install the win10 build we were offered. I'd install it yesterday in the evening but had to wait until hard reseting my phone in the morning.
In case the build is still active for you (was active for me an hour ago) don't install.
