I need a little help with my W980. Thanks :)

Well. My English is poor, so forgive me if you do not understand anything :)

I got my W980 flashed and it's new again. But I copied things to my phone, and the next day I tried to shut it down and tried to turn it on to see if anything is OK, when I turned it on, it was not on, It just keep automatically restart when a little vibration appears. What happened? So every time I turn off my phone I need to flash it again?:a005 Please give me some best solutions. Thanks for your time :)
