The spinning cogs issue is one that seems quite common when a Windows Phone smartphone is reset. When a user initiates a reset in the Settings menu, during reboot, the display gets stuck on the spinning cogs. Before now, if you got stuck perpetually this way, the only solution was to take the device to a support centre to be flashed. Now, Nokia has updated its Software Updater tool (to version 4.0.1) so you can deal with this problem by yourself.
Simply download Nokia Software Updater for Windows 7 and 8, and install on your PC. After installation, plug in your Windows Phone to the PC, launch the Nokia Software Updater and choose “My device doesn’t boot up” option. When the display indicates that your phone is connected, press and hold the power + volume down buttons simultaneously until the phone vibrates and a firmware download will be initiated. But this is where this procedure knocks me. The firmware to be downloaded is a whopping 1.2 GB in size!
At this point, personally, I will rather send my Lumia to Nokia Care than subject myself to this download. Think cost. Think download hiccups. Think endless breaks and countless hours (if not days). Think misery. Users in other parts of the world who experience much faster and reliable internet services will find this to be no issue. But for the most part of the emerging world, this 1.2 GB file download will be a pain in the behind.
If this floats your boat, download Nokia Software Updater right away.
