This has happened to me once and I recall someone else on the forum also had that issue. Just turn off the phone by holding the power and volume up together. The power button should work as normal after that.

Seems a software bug. Happens to me sometimes too.

How do I hard reset locked phone?

Hi,
I just purchased screen locked phone (requires password to unlock). I thought hard reset will fix it but it does not do anything.
I hope volume UP and volume DOWN buttons simultaneosuly while phone if off then press Power button and release it while continuing holding VolUP and VolDown but nothing happens - phone stays on locked screen. Does this procedure works on locked phones?
Mmmm...
Make sure you're holding the buttons in firmly while you briefly press the power button. It doesn't matter that the device is password protected, all the data will be cleared and set to default ROM settings.
If the device just switches on, it means that one or both of the volume buttons weren't completely pressed when you hit the power button
I tried like 10 times already. I hold both buttons very tight but after pressing power, it just comes back to unlock screen.

hold volume button down and press power button. if you can do this just flash a new rom from the sd card.
This does not do anything either. I hold vol down button while phone is off and press briefly power while still holding button and nothing happens. It comes to load screen.

its starts booting windows mobile? or tri color screen?

Hard reset
Be sure first that device (not the screen) is turned off, then:

Thanks,
I figured this out. I was so stupud, I understood phone is off is like screen is Off. It actually meant the whole phone is off instead (had to remove battery for that).
The First thing you need to do: Power-OFF your device.
since it's locked, software interaction may not possible. you need to take the battery out, and put it back in 2-3 seconds later
Then, hold VOLUP and VOLDOWN tightly, and hit the power button to start the hard reset procedure.

Thanks I solved my problem..

[Q] Flashed Rom. Now touch screen wont respond

I flashed this rom ( Sprint_HTC_One_1.31.651.2_Stock_Rooted ) . Phone booted and touch screen stopped working. I'm in a rough situation because the phone also will not reboot. I've tried holding all buttons, just the power button, the power and volume down button. No resolve. Anyone have any suggestions on how to make this phone reboot (besides waiting for battery to drain lol )so I can try to install another rom and see if touch screen comes back. Thanks
You need the newest firmware it sounds like

I cant do anything with the phone though because its stuck on the lock screen. Cant touch anything and cant get it to reboot
Oh and I accidently posted in the wrong section... wasn't sure if I should just leave it up or delete it
Just ask the dev to move it....hold the power button and volume down then release power after about 7 secs and press it again but keep volume pressed the whole time to get to boot loader then go to recovery from there

that would work great if the phone was off...but the phone is on the lock screen... When I hold the buttons It counts down 3....2.....1 then hangs at 1.. Ive held the buttons for over a minute no dice..... It seems the only way to reboot is through ADB but I cant allow my computer to connect to the phone because of the screen being locked... wish there was another way to reboot this phone without waiting for the battery to die

Hold the power button until the home/recent apps buttons at the bottom stop blinking...if it reboots let go of the power and hold vol down this will get you to the bootloader
If it does not reboot press the power and let it start to reboot and hold vol down
The buttons just continue to blink.. no reboot just stuck at lock screen

If you hold the power button down long enough it will power down or reboot
I held the power button down for over 2 minutes... should I hold it longer? Here's what happens, after holding the power button... on about 5 seconds in a message pops up and says continue holding power button for reboot. I continue to hold it and a count down starts.... goes from 3 to 2 to 1.... the phone just stays at one no matter how long I hold the power button in for

hmmmm never seen that before, try holding power and vol down see if it gets you to bootloader
Yeah tried that... pretty much tried all button combinations for all amounts of length....this is how stumped I am. I've been a member on this site for years and I think this is the first time I ever had to post a question about a phone. I seem to always find an answer but this time I just couldn't I'm baffled as to what can be happening and why this phone wont reset.
Yeah I mentioned that in an earlier post. I cant adb because I cant unlock the phone to allow the computer to be trusted by the phone... I have the phone sitting on the table with a piece of tape holding the power button in causing the screen to stay on and keep the endless countdown going... hoping that kills it quick..... I guess that's the solution to this problem if anyone else may happen to come across the same thing lol

How did you get yourself into that situation, lol. This is why I slightly perfer the Galaxy's because you can just pop the battery off. I get a HTC and just try and do as little as possible, and quad check everything.
Did you get it done atleast?

When you are holding the power button down and it starts to count down shine a flashlight at the light sensor to the left of the speaker on the top (or hold it under a bright light). I had this happen to me before where it wouldn't simulate the battery pull. Just sat there. Apparently the phone has a built in defense to not reset in low light situations in case you accidentally hit the power button while the phone is in your pocket. The flashlight on the sensor trick works. http://forum.xda-developers.com/showthread.php?t=2314952

Are you pressing and holding power + volume up + down? Takes about two minutes.

Power button not working

Hi to all.
I'm new about this phone. I have purchased It only 3 days ago and i have an issue.
When i press the power button for shutdown or restart the phone, the menĂ¹ not appear.
Nothing appen.
For shutdown or restart the phone i have installed the shutdown app from the store .
Anyone have this issue?
Thanks a lot
I've heard that Power button + vol up does the trick
It's a very very annoying feature. A power button that has no correlation to powering off the phone.
To shut down. You have to press and hold the power button and volume up key together and you will get the option to switch off/restart your phone.
Before you ask. Lockdown mode doesn't exist. Very useful feature that isnt on this phone.
They made it like iPhone...it was better on x2 pro like all other Android around untill now .
Thanks a lot ..
Works vert well
