Unhappy [Q] My Galaxy Legend is on Boot Loop HELP!

Hi

Sorry to be very obnoxious but when I took off the battery from my HDC Galaxy Legend which is a Samsung S4 1:1 Clone and restarted the phone starts till the home screen and goes on a boot loop.

I went to recovery and erased cache and factory reset and yet its persisting.

Any suggestions and my phone is not rooted. Please HELP
