Samsung A707 Stuck at startup screen (loop)

My samsung a707 turns on and gets stuck at the startup screen ( with the At&t sign ) and after a while it turns off and back on again in a loop.

I tried taking the batteries out and wait and putting it back in but it doesn't work...

I dont have any data on it so it is ok to factory restore... I dont want to take it to a store to get it fixed...

Any suggestion like how to hard reset on startup screen will help

    I ususally loops it until i take the battery out, last time i tried it it turns off by itself after a few seconds so I assumed that the battery is out.

    I Pluged the charger in and the phone turns on by itself showing a empty battery screen with the yellow/orange loading bar under it. the bar runs to about 90% and stops, after a while it turns off and turns back on with the normal start up page and loops like before.

    So i left it running for a few hours and when i took the charger off and it keeps on going so i took the battery out but it still doesnt work.

    Sounds like perhaps there's a short on the power button inside. While it's off, even if you plug in the charger, it should not turn itself on and go to the main screen where you can make phone calls.  It should just show a big orange battery charging or when it's done, it should say something like battery fully charged. If the battery never charges to full, then the battery may be dead, you can try a good battery at some cell phone store w/o buying it, if they have one sitting around already.

    This also happens when the battery is close to the end of its life.  Make sure the battery is still in good condition and fully charged.

No hard reset wont help!You should try following to get rid of this problem:

  • Change your phone's battery.
  • Change your charger.
  • Hard reset wont be possible in this case.
  • You should also consider charging your phone for long time but still if does the same loopy thing then change your charger.
Thank you and good luck!
