[Q] Phone freeze, hold down power to reboot, BLACK SCREEN FOREVER - Sprint HTC EVO 4G LTE

I have heard of this problem before but I can't seem to find any way to fix it.
I was in an app, the app froze but haptic feedback was still working, held down power to restart, phone vibrated but nothing on screen.
I have not had any screen problems before.
What do I do to fix or troubleshoot this?>
Thanks

can you access recovery?

Did you try holding it down for 30+ seconds? It can sometimes take a really long press to trigger reboot.

It looks like you may have a hardware issue (on the board). Did the phone get wet or damaged in any way?

I know that the hardware starts acting funny if it get wet since the contacts for the buttons can short out. I would get HTC to take another look at it. Also, make sure that you are not damaging the device accidentally by crushing it in your pocket or things of that nature.

Can't get a shutdown menu on my CM7 touchpad.

For some reason I can't shut my touchpad down. If I hold the power button down, not much happens until I release the button. Then the screen turns off. Tap it again and it's back.
Any ideas?
thats strange try a hard reset, hold the power button and the home button down for literally a minute or so or until it resets. it will reboot into moboot hopefully. you might have to do that and go back into webos to completely shut down. good luck
Thanks for the reply, I was just trying it when the battery ran out!
But I'll give it a go if the problem returns, thanks.
Ran into the same problem today. The power menu, along with various power/reboot widgets wouldn't work, but after about 20 seconds of holding home+power it worked and booted to moboot.
I had this happen to a coworker, after I had recently upgraded her to alpha3. I tried everything to repair it before deciding to start from scratch. The best thing to do is restart using the power and home buttons (hold them until reboot).
Then think about reinstalling.
Good luck!

I had this same issue today. I downloaded Quick Boot from the app store and it allowed me to restart. Worked great
just happened me too, it MAY have something to do with low battery, i noticed someone above had the problem with low battery. mine happens to be low too
also, i turned off lockscreen earlier, maybe that was related.

[Q] Power button problem

Heey i have a problem with my power button. Had this problem before but it was gone after one day. The problem is my powerbutton isnt functionaly like it has to be. It changes from time to time.
Sometimes it doesnt work at all when i push the powerbutton.
Sometimes it works slowly. And when i have pushed te button couple of times, i get a phone with screen on, off, on off etc. Like it has lag or something.
When my powerbutton wasnt working yesterday, I saw that the button was pushed the whole time. I mean when you push powerbutton and homebutton you make a screenshot. If i only pushed the homebutton it was making a screenshot.
This things change from time to time. Any one got any ideas????
Im not even sure if its my button that is failing or it has to do something with software.
btw i already tried reflashing rom and kernel with no result.
thx in advance
It's the button, not the software that is the problem. Try taking off the back cover and cleaning out whatever dirt/lint that could be under the button.
i tried that already but it doesnt seem to work. Looks like i have to go back to stock rom for warranty. Hope this is going to be possible since my powerbutton isnt working.

Phone started acting buggy. What can i do to fix?

Stock
It stays on a black screen unless i plug the charger in. I can then operate it for a while. But then all the sudden a message permanently stays on the screen saying "to restart your phone, press and hold the power button and volume up button for 10 seconds". also after this message appears the home button reacts by taking a screen shot (weird).
I have tried rebooting it and updating PRL check for software updates. Don't know what i should do.
I can't even boot into stock recovery because it won't power down it will just reboot. So i can't turn the phone completely off.
Anything i can try?
Try pushing your power button rapidly many times. It is probably stuck you may feel it... This has happened to me a couple of times. Maybe try some compressed air around it.
Ahhhh... Max Venom injection! Much better now...

Issue has been solved but looking for explanation

So my friend's stock s3 started randomly rebooting recently and just couldn't get to the home screen without many tries. And it got worse this morning as she had spent about an hour to no result. The problem is the phone would keep rebooting during the GT-I9300 screen.. Most of the time it wouldn't get to the Samsung boot animation.. If I charged it, the battery logo would be shown as loading instead of charging.. After trying the hard reboot combination a few times which didn't work, I noticed that I could see the battery with green bar every time I pressed the power button!
So I tried something silly.. I kept pressing the power button repeatedly during boot and surprisingly it booted up to the home screen. However, without being charged, the phone would still suffer from boot loops (at that moment we confirmed that the pressing power button repeatedly would 100% work) . As we were desperate to understand the problem, I got to know some apps that she installed recently and uninstalled them. These are the apps that she recently installed and later uninstalled:

https://play.google.com/store/apps/details?id=com.fourricegroup.mc
https://play.google.com/store/apps/details?id=com.naturalmotion.clumsyninja
Guess what?! The bootloop has not happened till now! So the reason I'm writing this post is because of curiosity xD
1. How does pressing the power button repeatedly help the phone to boot up? If I stop pressing it before the locksreen, it would fail.
2. Can an app really cause a weird issue like this? Or is it just a coincidence that the phone magically got better after uninstalling the apps?
Hope to get some answer from you guys for learning purposes thanks in advance!
Sounds like your power button is faulty.
