HTC ONE S keep rebooting all the time! Help :<

My phone keeps rebooting all the time. It goes up to the logo screens and the shut downs and reboots again ad infinitum :// Is there any fix for this? Phone is not rooted or anything. This blows so much im out of the country for 2 weeks so i cant get it fixed :///
Hold Power button, all screen buttons will flash for about ten secs. Release, phone should turn off phone.
Hold power and volume down. That should take you into your bootloader menu.
Select "reset". This will wipe your SDcard.
should work on your stock device but try at your own risk. Just remember, google is your friend.

Yeah, just Power-On button + Vol - and then Factory Set. Use Vol+/Vol- to navigate in the menu and power button to select. :good:

Phone won't boot up

I have researched the "related threads" and none are similar to the issue I am having.
The phone turned off midcall and fails to turn on afterwards. I thought it was the battery, but it still fails to turn on after charging over night.
It boots up to show the logo, after a battery pull and turns back off.
If I I press down the power button + down volume+ menu, I get the warning about a custom install of an OS may damage the phone and if i want to continue to press the volume up, or cancel.
The phone only lasts about 5 seconds, after every battery pull, other wise it won't turn on again.
I haven't gotten a blank white screen nor the Android logo.
Thank you.
Update: I believe I confirmed it is a power button issue.
What I used to confirm it was pressing the volume down button and menu without the power button and was able to see the Warning as if I had pressed all three. Also, the phone vibrates as soon as I place in the battery.
Issue now is: Supposedly the cause is due to a stuck power button, but physically the power button is not stuck. It clicks when pressed.

but as my phone did not support monitor mode so I just uninstalled the nethunter and qll it's apps but I think it did not remove the downloaded 4GB data with it so I thought maybe I should hard reset it so my phone would also refresh.but as I went into recovery mode by pressing the power and volume down keys then pressing the volume up key and the power key again (that's how I always goto recovery mode in this phone) then I came down and selected the wipe/data reset and again pressed volume up key (for selection) my phone at first kind went blank then I pressed the power button and it showed the android guy settings logo with a yellow line in the bottom "wiping data" I left it like that for about 10 minutes but as it wont go forward I pressed the power button for about 15 secs and my phone got restart and went to that very same android guy logo with the settings pentagon but this time the yellow line and the text were gone and it's been 5 hours since my phone is stuck with that android guy logo.even If I try to connect it to pc after turning it off using both the volume keys and the power key that android guy soon restarts after getting pc connection. what do I do please. any kinda help would be appreciated
and thanks a lot in advance
