My money is on a hardware failure. Do you have a stock ROM ?

hey yea i went and unrooted and reinstalled my carriers stock ruu....still same problem.looks like taking it back to the shop for them to fix

Hey actually exactly one week ago my Desire started the same exact thing, and I could not find help anywhere. Best info I can find is that it might be moisture, but at least for me I don't think that is the case.
I ended up taking the whole phone apart (been taking stuff apart all my life, but i was still nervous) to clean it out since I've had dust in the screen for a while... I think I cleaned it out pretty well, but did not take the plastic tape off the button. This did not immediately help, but after playing with it for a while it now works most of the time, but is quite sensitive usually.. the button "presses" before it mechanically "clicks".
Anyway, If you were to become desperate enough to try this, I would recommend pulling that black plastic tape off the button when cleaning, then stick it back on. Good luck
I've been lusting after the Sensation anyway

yea im not into pulling stuff apart that i got no idea about...took it back still under warranty n its getting sent in for repair...now stuck with a piece of **** samsung omina icon....windows phone sucks the big one very hard...ill be going back and asking for at least an android as a loaner while its in for repair

ohh well that's good that it's still under warranty. I was actually using the camera at a beach during hurricane Irene and that night the power button went berserk.. continuously turning the screen on and off... before eventually just staying "pressed" all the time again. So maybe the moisture theory isn't all that far fetched in my case (I was at a beach the first time it happened, but never went near the water)
Currently trying to get a broken Desire on ebay to harvest for parts :/

Moisture - Htc Desire Power Button.
Hello,
I've met with that problem.
I've unscrewed the device, I've remove the black tape, and I've used a cotton swab to clear it.
But the problem was solved, but later withing the 24hrs, It's back to auto on/off without pressing the button.
I would like to know, Should I remove the yellow transparent tape on the button for cleaning?
Thanks.

[Q] Stuck in Bootloader

My phone's volume down button appeared to be stuck. It's not physically stuck but the volume pop up would come up all the time and turn my volume all the way down and vibrate. I installed Quick Settings hoping that would override whatever was causing the issue and it seemed to do the trick except I'd still get the random vibrate from before it just wasn't turning down my volume. Then I tried turning the volume down with the volume rocker and it didn't respond. I could still turn the volume up, just not down.
I unlocked my bootloader yesterday in hopes of rooting but I never got around to actually rooting my phone. I was going to do that this morning so I pulled up cmd and threw in the command: fastboot flash recovery r1-modaco-recovery-clockwork-touch-endeavoru.img. Then I realized my phone was still on *facepalm* so I tried to power down but the power down options weren't popping up like they're supposed to. So I held the power button down to force the power down but instead of powering down, it went straight to the bootloader screen.
Now here's the problem... my volume down button still does not work and to make matters worse, my volume up button and my power button are acting as the volume down button. In other words, I can only scroll down. I'm unable to select anything or power down.
Any ideas?

After pondering for a while, I'm thinking that this is a hardware issue and the volume down button is defective. I notice that when I push either the volume up or power button, the cursor doesn't move until I let go. That leads me to believe that the volume down button is still stuck so when I push another button, the other button doesn't do anything (similar to power windows in a car where the driver is trying to roll a window up while the passenger is holding the window down button and the window just sits there) but when I let go of it, the volume down button resumes and moves the cursor down.
The worst part is, I've been in Germany for three days and I've only had the phone for two. I don't speak German (I'm a lazy military husband who figured submersion would be the best way to learn) so turning this in for warranty is going to be a major pain in the ass. *sigh*

Hi, sorry to hear you are having problems,
Since you haven't actually rooted the phone and haven't made any modifications, you should be able to return it for warranty. This would have happened even if you weren't trying to root the phone; just powering it down. So yeah... Seems like warranty is your only option I'm afraid....
Good luck

I figured the warranty should still be good. I'm just hoping I can do the warranty exchange in the store like they do in the US. If not, then I hope I can call the US customer service. If I have to go through the German customer service, it won't be fun (because I don't speak German, I'm sure they're helpful if you can communicate with them).
I was able to "unstick" the button about 30 minutes ago. I read that there's a creaking noise if you squeeze the lower corners of the phone. I squeezed the phone and sure enough, it creaked, but only slightly. Nothing to worry about. But I did see that familiar rainbow looking wave in the screen. So I squeezed all up and down the sides (to this day, the rainbow distortion of LCD screens still mesmerize me) and that inadvertently unstuck my volume down button. It has still stuck a couple of times since but it stops when I squeeze the screen near the button.
I'm still going to turn it in for warranty, but at least I can play with it until then.

Ah did you got it booting then?? I would get it to an O2 store ASAP if you bought it from your carrier. If its an unbranded phone you could try going into a German phone shop to see if they'll replace it. Most people working in German shops should speak a fair amount of english, so that won't be a problem.
EDIT: Oh and before you go numb looking for one; Germany has no O2 stores I think...

Hey,
I'm happy you were able to fix it. As for the warranty thing. Technically you void it by unlocking your bootloader, no matter whether you rooted it ore somesthing. But as this seems to be a hardware issue that can't be caused by software (like frying your CPU by overclocking it).
Welcome to Germany! Normally stores won't return it, but sometimes they offer to send it to HTC for you... If you're lucky and you bought it at "Media Markt" you should be fine though. They usually do that kinda stuff, if you got it from O2, chances are low they will just give you a new one. Sorry

Yes, I am able to boot back into the OS. There are O2 stores in Germany, that's where I bought the phone.
Thanks for the info guys, I appreciate it.
Sent from my HTC One X using XDA

I wanted to give an update to this situation in the rare case that I'm not the only one who has experienced this problem. I ended up taking my phone back to the O2 store and they sent it off for a warranty claim. During this time, I was given a Motorola Milestone as a loaner. It was small, slow and frustrating but at least it was a Google phone. Two and a half weeks later, my phone was back. The verdict? They could not duplicate the issue and therefore did NOTHING! I was so frustrated because I felt like I went without my phone for absolutely nothing. The O2 staff did tell me that if I send the phone back to the warranty claims a second time and they don't find anything again, they will replace the phone. But did I really want to be without my phone for another 2+ weeks? After all, I did find a quick temporary fix for the issue. I decided to hold onto the phone in hopes that I could better understand the issue or even live with it.
After a few more weeks with my phone, the issue was getting more and more difficult to "fix" until eventually, it wouldn't fix. I still used the phone for a couple days until it froze up, rebooted and went straight into the bootloader where it stayed at full brightness until it died. I couldn't shut it off nor charge it. Essentially, it was bricked. I went back to the O2 store again to send it off for warranty. This time it took an agonizing 3 weeks and again, they couldn't fix it. But this time they sent me a brand new phone! Yay! So now I'm sitting here with a fully functional awesome Android phone. It was rough going 5+ weeks without my phone but I'm happy now.
Recap of key points:
- HTC One X
- Unlocked bootloader
- Rooted
- Custom ROM
- Had a hardware issue
- Sent in for warranty... twice
- Phone was replaced after second warranty attempt at no cost

screen black, but phone works. Help please.

Hello everyone,
phone was fine, then took it out of my pocket to find the screen is black. I was low on battery, so charged it for a bit, but no difference. When I press power, it becomes a brighter black, but thats it. Phone works when someone calls, obviously can't pick it up though, and I see the notification flashes. What can I do?
The phone is unlocked, but S is on. I don't have insurance, but previously Sprint helped out with the 35 dollar flat rate fee. Will they do that again if unlocked?
What are my options? Thanks everyone.

First off, reboot the phone. Either use adb reboot or just pull the battery and put it back in. If that doesn't work, boot into the bootloader. (hold power+vol-down while the phone is off.) If both cases don't give you anything on the screen, chances are your backlight is just dead. Even those tiny LED's burn out, but they're supposed to last quite a while.
edit: by "unlocked" do you mean you unlocked the bootloader? If so, then the warranty got voided when you did the unlock.

dohyste July,
I pulled the battery multiple times, didn't work. Tried booting into bootloader, didn't work either. When I press the power button, it gets a bit brighter, but don't see anyting. yes, I unlocked the bootloader. The warranty would be void, but how can they even check if the screen is not showing anything? Also, they said my warranty was up at the year mark, so would they fix it or replace with the 35 dollars

Check to make sure the "getting brighter" isn't just light leaking from the haptic buttons at the bottom (home/menu/back/search). Otherwise, I dunno, sorry.

do you guys think if I changed the upper half of the phone or just the screen, the problem would be solved, or possibly a software issue?
thx

Perhaps it's something simple as getting a new battery?
How old is the current battery?

the battery is the original. It's a two year contract and I'm up in January, so about a year and a half old battery. The phone was a replacement I got last week due to bad speakers on the first one, but the battery is from the original phone.
I also tested to see if the touch screen works by calling myself. I was able to pick up, so it's the screen only as it seems.

[Q] Power/Lock button unresponsive

Hi everyone, so my Power/Lock button on my Gnex came unresponsive as of last night.
When i woke up this morning it worked! but only once , then randomly it just started working again, and then 10 minutes later nothing.
When i pull the battery, and put it back in it will power on immediately.
At the moment, if i press it, it will work once, then wont work again for another minute or so.
I'm running a custom rom, i did a reset, cleared all my data and it still persists. Running CNA, was thinking of trying to flash back to Stock but the custom rom allows the option to wake the device with the volume buttons, which is the only reason i can even wake it at the moment.
Its still under warranty, however i would go a atleast 2-4 weeks without seeing the phone and have to send it away.
I was thinking of opening it up myself (following the dissasembly videos on youtube, only need to remove 6 screws and use the little plastic pryer to seperate from the screen i think.)
Heres pretty much my question:
With the Galaxy Nexus, is there some sort of sticker that will be broken once i open up the phone that will void the warranty? If i can't fix it, will they know that its been opened?
If not, i'm going to open it up, see if the connector has come loose or something which is what i hope, otherwise for $5 i can get a replacement button & ribbon off ebay, which i would prefer to do then go through the hassle of sending away for warranty.
EDIT: Also think the reason the connector has become faulty is due to water, it was raining last night and was using my phone as a flashlight to walk up the backyard of my house. It got exposed to the rain, Everything was fine, but when i plugged my phone into the charger was when the button stopped responding. I'm guessing some water must have got into where the power button is.

"Do or do not, there is no try." I was gonna suggest the ifixit or adam outler's vids as to if there will be signs its been opened, but it seems you've already watched those videos.. supposedly the led will be lit red if there is a more serious internal water damage issue, which would completely void your warranty, i believe, so it seems like you may have to tear it down.

[Q] Disable the Power Button

Ok, so I got stuck in the dreaded stuck power boot loop. After mashing the button for a bazillion times, blowing on it, spraying it, hitting it with various objects, it worked! And so far it has been working. But I don't want anything like that to happen again, where it will just shut off on its own due to its own crappieness.
Can you disable the power button, so that the only way to turn off the phone is by using power tools or some other widget?
I want nothing to ever happen when I press it, or when it decides to magically make contact with the inside of my phone.
I can't get inside the phone to deattach the connectors, because here is me -----> (O.O) here is my screwdriver ------> [=====+ and here is the screwdriver tip when I tried to open the phone ------> *snap*
So I now have a screwdriver tip stuck in one of the screws, and I am locked out of its innards, which may be a good thing
Any way to modify the code to disable the power button?

Please help! My phone went bananas again and after shaking it around I got it working again. This is an urgent matter, I can't use my phone like this.

It sounds like you tried most of the stuff in this thread already:

If nothing there works you may have to send it off for repair.

Ach! Do I have to unroot PA and reset the flash counter if I give it to T-Mobile? My phone is a refurb, it's replacing a broken, really old HTC that no one makes anymore. What a hassle! All for one tiny defect with HUGE consequences! I am still under warranty. I don't know of any good local phone repair shops here in Hawaii, may have to mail it in.
FML, today's my birthday, and I may have to pay for another phone.

Well, at least you are still under warranty. I am not sure what happens when you send it to T-Mobile. Hopefully someone with experience with that can chime in.
Good luck and happy birthday.

Heh, been eyeing the nexus 4, even with its flimsy back. I can always get a case.
Yeah, hopefully it doesn't decide to go bonkers on me again. So far it has not been turning itself off and on or getting itself stuck down, but you never know...I'll see what my options are from here on out.

I can tell u from a friend that works for tmobile service department that when u send it back for repair they most likely won't even turn it on, especially with your issue all they'll do is their it in the refurb pile and send ua new "refurbished" phone so no it won't matter if u leave it rooted, your going to get a different phone back anyway unless u personally bring it to a 3rd party repair place

The power button's function is hardware based. No way to disable via software.
