Windows 10 Mobile update crash

On my Lumia 925, originally sold with Windows 8.1, i installed the official Windows 10: at a certain point i made an hard reset and the phone automatically downloaded Windows 10.
The hard reset was done when i was not able to install updates on the Windows 10 preview (from Windows Insider); now there were an update for the official Windows 10 ending for 107, if i remember well, but the phone was not able to complete the install.
I noticed that continuously tapping on the screen, in order to avoid the phone standby, the procedure was able to end, but after the reboot the screen showed 2 gears and then a big sad smile , as this ->     : – (
No way to reset hard or soft, at every reboot the gears and then after a few seconds the dreaded smile: i was already thinking to buy a new phone.
But i discovered the Windows Device Recovery Tool, that after the downloading of 1,65 gb has installed a working Windows 8.1 on my phone; and then using the Windows Phone Developer Registration 8.1 (installed with Windows Phone SDK 8.1) i re-registered the device in order to publish on it my apps developed with Visual Studio 2013.
Thanks to Google sync i lost nothing of interest, but anyway i will be suspicious about updating the 925 to Windows 10..

Microsoft Xamarin

Microsoft has acquired Xamarin.
Interesting project, but you must have a solid mobile business for each major environment (Ios-Android-Windows Phone): even for MSDN subscribers the editions are still not cheap, Xamarin Business is 799$ for developer.

WinPhone 8.1 vm failed to start

I’m trying Visual Studio 2015 in a Vmware Workstation virtual machine , and trying to start an WinPhone 8.1 Hub application i got:

The emulator is unable to verify that the virtual machine is running:
Something happened while starting a virtual machine: 'Emulator WVGA 4 inch 512MB.test' failed to start. (Virtual machine ID <a guid>)

The Virtual Machine Management Service failed to start the virtual machine 'Emulator WVGA 4 inch 512MB.test' because one of the Hyper-V components is not running (Virtual machine ID <a guid>).

After some head scratching i found that in the Vmware vm processor configuration must be enabled “Virtualize Intel VT-x/EPT or AMD-V/RVI”

And in the .vmx file must be added the line

hypervisor.cpuid.v0 = "FALSE"
