Windows 10 preview update failed in Nokia lumia 720

Hi,

I was trying to update Windows 10 preview version from Windows Insider program on last Sunday. And it was successfully downloaded the updates and installation also almost done, but at the end it shown ":-(". And it continuously showing installation icon. I'm unable to rollback my changes. Could anyone help me in recover my mobile phone back to Windows 8.1.

TIA.

I Have This Problem Too But It Happen When I Download WP10 And Decided To Reset Cause It Crash A Lot and When Reset The Bar Is Stiil 1/8 And Suddenly Goes To Full And Show :-( As Well
And It Turn Off By Itself And If I Turn On It Willl Show The Reset Bar And Show :-( Everytime I Turn On

Someone Answer In My Post About Error Windows 10 Mobile Reset To Download Lumia Software Recovery Tool On PC/Laptop And Im Still Downloading 8.1 On My Laptop (93%) U Need USB Cable From your Phone Or Other Compatible's Phone Cable But A Good One And Maybe The Problem Is When U Install It U Dont Charge It So Low Battery Could Be The Problem.

Hope Ur 720 Works.
