Hi
Check you power button.....maybe stuck

I don't think it's cause by the power button. Once the phone is in the process of booting up, you can't shut it down with the power button. Only by removing the battery.
Is your phones battery ok? I had a similar issue with an LG P350.
Sounds like a hardware problem though.

1)The power button is not stucked !
2)I even tried with another battery, same !

can you get into recovery by holding the volume down button when the phone is off and then powering the phone up while still holding it down?
as long as it turns on and screen comes on, you are not bricked .. it's almost impossible to birck this phone ..
can't get into recovery at all, phone is not responding to anything just constantly stuck on initial white htc screen. have backup on sd though no way to get there through phone
how can pulling the battery not work? If there's no power to power up the screen it should die instantly
Try keeping it out for like 10 mins or more.
Then go to recovery and wipe/reinstall from backup.

And to get to recovery you have to start with the phone turned off (by pulling the battery). Then put in the battery and before you press the powerbutton, press and hold the vol- button down. When you're holding the vol- button, press powerbutton until the screen turns on, keep holding the vol button until you get into the bootloader just in case. From bootloader you can choose recovery with vol+ and vol-, powerbutton to select.
And as long as there's something happening on the screen (e.g. HTC logo) it's not bricked.
cheers Hawks556, all is good now

Your phone should not turn on by itself after inserting the battery.
So it's definitely something related to the power button.

S4 keeps turning off after a few seconds

hey!
I own a Samsung Galaxy S4. Since today I cant boot the phone up anymore!!!
while watching youtube videos it sudddenly was dead, I didn`t even drop it. turning on again with the power button doesnt work, advanced boot with power button + other button doesnt work as well. only if I reinsert the battery the phone vibrates and it turns on for about 2-3 seconds, the samsun bootloader logo appears and its dead again. I have already replaced the battery with a working one, doesnt work. I removed the sd and simcard but that did not help.
Sounds a lot like a power button problem.
The exact problem is that the button is stuck or shorted, which causes the circuit to be constantly closed. In other words, it's always "pressed".

can't make hard reset nokia 6

hi
my little brother made a pattern lock and forgot the pattern, after many tries the phone erased everything
he doesn't know the email he used it on phone or the password
now it boots welcome screen and asks for the old email, i did tried make new but it doesn't works.
so i figured i should just wipe everything with hard reset
from what i read and saw some videos, i should turn off and then connect to power then wait a little, then press power and vol up for 10 seconds then release my finger from the power button.
i tried it many many times but it doesn't works.
any help?
Switch off your phone,then connect the charger to your phone and quickly press and hold volume up and power buttons,after the screen is blinking a bit release power button,but hold volume up until you are in recovery mode.
it doesn't works, it's like the vol up doesn't work when the phone is switched off, but when i power on the phone and finish booting i can vol up.
i can enter download mode (vol down + power) but it doesn't do anything.
