Galaxy s4 boot loop problem

[DavidCool]

Hi,
My galaxy s4 do boot loop.
when I put the battery inside, the phone turn on (I don't touch the power button) and do boot loop, like someone hold the button power.
when I enter to download mode, after a few second the phone do boot loop again.
the power button can be pressured.
thank you very much.
(sorry for my bad english).

Had this problem ("grey battery icon"). Different battery WILL NOT help. Phone needs to go to an AT&T _REPAIR_ shop. There was one near me in Los Angeles and they fixed it in 10 minutes.
