Windows Device Recovery Tool is Microsoft's official tool for resetting and recovering software on phones with Windows Phone 8 or later. This desktop application is aimed at Acer, Alcatel, BLU, HTC (One M8 and 8X), LG, Lumia, NEO, UniStrong, VAIO and Yezz phones, as well as HP devices. However, before we decide to use Windows Device Recovery Tool, we must try to restart or reset the phone.

If this does not solve your problem, there is nothing else left to do but to install this tool. However, you should bear in mind that Windows Device Recovery Tool not only installs a new version of Windows mobile version, but also deletes all data from the user's phone, so it is extremely important to back up the history of calls, messages, applications, games or multimedia contained in the memory of the portable device.
