Not able to revert back to 8.1 after updating 10 insider preview I upgraded my Lumia 520 to windows 10 Insider preview. Now the phone hangs a lot and its getting too slow. It also displays message of low storage space even there is lot of space left (about 3.12 gb) on the divice. Now I have decided to revert back to 8.1. I tried resetting to factory, hard reset and even I tried the Windows Device Recovery Tool. WDR tool shows the same version on server which is installed on my device which is "Firmware Version: 3058.50000.1425.0001" saying You have the latest available software version. Even though I tried to reinstall, the download process is never completed. It starts and then after reaching about 8 percent, it stops saying there is error in downloading. Can any one suggest a full-proof way to downgrade windows 8.1 from 10.? 8.1 insider-preview lumia-520 windows-10
