I powered it down and tried to turn it back on... but the screen is just black nothing will bring it back.
tried volume + power to get into recovery... nothing
is this thing dead? or am i missing a hard reset?
Help?

Take the battery out for 2 minutes. put it back in. Do not turn it on. Then plug it into the charger for 10 minutes and then power it on. Might sound like joke but I'm dead serious.
**EDIT**
Its possible the things battery just died. If its completely dead it wont do anything I've scared myself like this once as well. If this does not work try download mode. The fact alone its not rooted tells me it might just need some more charging time.

Try out the T-989 Toolkit posted today in the Development section. Maybe that can help kick it into Download mode
Sent from my ICSed T-989

The battery works tried another one and tried removing it with the charger connected and it seems like it is a power issue because it also vibrates with the charger and no battery

For anyone, when your phone vibrates every 2 seconds while off and connected to a power source, unplug it, replug it and DON'T DO ANYTHING! Wait for the battery to charge up and it will boot itself.

SGS2 Dead - Vibrates only

I have a Galaxy S II (I727) that is just vibrating (after it dropped from a desk to the floor). I can see a hairline crack in the glass at the top right corner if you hold it at the right angle. Though the buttons all still click, it doesn't respond to any combination of buttons. The battery is fully charged and tested on a voltmeter. Connected to a power source with the battery out, it still just vibrates every second or two. The only way to stop the vibrating is pull the battery. It's out of warranty, so I'm up for trying anything. Help?

My phone wont charge at all - urgent suggestions needed pls! :(

Woke up this morning after leaving my phone on charge to find that it wouldn't turn on - I unpugged it for half an hour and then tried charging it at the mains again, still no orange light after leaving it for an hour - then tried differemt cables and points, no luck - then tried a power pack and car charger, no luck - before I send it to get repaired, is there anything else I can try? Really don't want to be without my phone for a week or 2 as I don't have a spare

Try using a different USB cable, try plugging into pc n see if it is picked up and also try holding vol dwn and power while plugging it in that worked for my mate

HTC One X Won't Power On Or Charge

Hey, I got a HTC One X today and used it for about 2 hours, and after going into location settings the phone froze for a while, then eventually it switched itself off. I couldn't get it to switch on, and when I connected it to the charger, I noticed the LED was no longer lighting up when connected to the charger.
So I done some reading, and heard that if you hold the power button for 10 seconds, its basically the same effect as pulling the battery on other phones. So I held it for 10 seconds and the phone booted up, it got the the lockscreen straight after booting up, when I tried to unlock it, I realized that it was frozen again. Then after a while it powered itself off again, so I tried to power it on, once again it was not working. So I tried holding the power button for 10 seconds, this time its not working, no matter how many times I've tried it doesn't work.
The phone wasn't rooted, I never done anything to damage it, I read that if you hold the power and volume down it will go to the bootloader, where I would be able to factory reset the phone, but even after hold those 2 buttons, still the phone is showing me no sign of life.
What should I do?

try to put in under charging, is the led red?
if it is, wait 10-15 minutes and try to go into fastboot with power button and volume down, and do a factory reset, or fist you wipe all your things try again to boot it up, maybe it was just without battery charge. is your phone new? or it's secondhand?

The phone is second hand, but condition wise its practically new, there's doesn't seem to be any damage, and its still under warranty, the seller said that he never had any problems like this.
When you says "put in under charging" do you just mean charge it? If so I have done that with both the computer and the AC adapter, and the LED is not lighting up.

remove this post plz

Try plugging the phone into your PC via the official usb cable,
I know you've done that, but Whilst it's plugged in, press volume down & power at the exact same time and keep them held until your bootloader screen shows.
The good news is, I've had this happen to me - i just kept trying.

Tried this, didn't work, tried again to be sure. I can't believe I have such a nice looking phone infront of me and it won't even switch on.
Some people say leave it connected to your computer for about 10 mins, so I'm going to try this now.

Yeah, I you should be leaving it plugged in.
Next step is to get Android SDK installed on your pc, even though it appears to not come on, you might still be able to run a fastboot charging script that will force your phone into its bootloader.

I have SDK installed, used to use it for my G1, not sure if things are the same for the One X. But what your saying kind on sounds promising.
I will look around to see how I can force that, or do you already know how?

Update your packages on Android SDK
place the fastboot charging script in the same folder that fastboot is located on your pc
Usually: C:/Android-SDK/platform-tools
Double click the script
I have the script, it but won't let me share it to you.
It's on XDA though somewhere.

I'm looking for it, but I can't find it.
Doing a search for "fastboot charging script" doesn't find me much to do with it.
Would you be able to upload it to mediafire, or anywere else?

Ok, downloaded, and tried it now, but it only says waiting for device, so I guess its ain't being detected at all in this state.
The phone was connected for about 30 mins now and still the LED won't come on.

Leave the phone connected to the charger for a few hours. If it doesn't want to work, try pressing various combinations of volume and power buttons. Otherwise I suspect you have a brick.

Does you phone (charging light) give one blink after you connect it to charger.
My does after 10 sec. But still no power up

I left the phone connected all night last night, and still the LED didn't light up, I tried every combination. I don't think its a brick because I wasn't doing anything at the time, and the phone wasn't even rooted.

Mine doesn't blink at all.
The thing I notice aswell after leaving it charge all night, is that it doesn't even get slightly warm. I can't believe HTC get away with releasing faulty crap like this. I had a 2 hour teaser before this started... Good job HTC.
Edit : Oh well, I gave up, I tried everything and anything and it wouldn't work, so I've sent it to HTC for repair since its still under warranty.
Edit2 : It took them a while, but there finished repairs now, and its on its way back to me. They replaced the Mainboard and the battery.

hello..just for sharing,.just now i woke up from bed and see that my phone cannot turned on.. you know what, during charging last nite, i forgot to off the screen(press the on button) so that my phone screen was kept turning on all the night,,.. i'd try to connect it with the charger but it still didnt work.no LED at all. after i read the comment from some of u, i decided to connect it to the PC .. fortunately, the red LED came out..
after wait for sometimes it was turning on..but sometimes can turn off back... its because of the bttery.. anyway, im so happy now.. hahha :laugh:

htc one x red light flashing and phone won't start

I have bought a htc one X a day ago, which was imported from some eastern country. The phone ran well for an hour or something.. and after that, it just dropped dead. The battery was about 60% when it dropped dead. And when I charge, the red light keeps on blinking. It won't turn on, or the red light will not be stable.
When i try to boot into bootloader, the phone does go into bootlader. But I have to keep my charging plug on. If i remove even for a second. the phones switches off again.
I can't go to warranty as this is a replacement. Some guidence will be appreciated. Thank you.

1. Charge the device for at least 10 minutes
2. With the device truly OFF (NOT ON STANDBY) , push in and hold volume up and volume down AND power button And HOLD for 2 minutes and let go once 2 Minutes has passed.
Doing this will calibrate the Circuit within the battery charging system.

If the phone doesn't power on & If the red led doesn't turn on while charging your phone then you should take it to service centre.. Might be a problem in battery or the motherboard

There is a batch file running about that helps charge from boot loader.
On phone so can't find it currently.

Did you ever get to the bottom of this? I'm currently in this situation myself. I read the thread suggested here, but it helps very little if you can't even get to fastboot. For what it's worth, I do have a custom recovery, but a stock image. And the mother board is okay - I've swapped in a different battery and that seems to work, but I do want to get my original battery to work...

guys i have a solution i guess .. put your phone connected to laptop or computer for several minutes dont remove . it might take sometime and afterwards you will listen the usb connecting voice and the blinking will stop and will be stable and then you can turn on the mobile

If you have a flashing power light
This is when your device has overheated and wont let you start up your OS.
Plug your phone in for afew minutes then hold down the power, volume up and down buttons at the same time untill a white developers screen comes up, disconnected your device from cable and click on recover and leave for a minute then plug you power lead back in and leave again. When you come back to you phone it the LED should be a solid color and you can then boot your device.
Any problems Message me, any time.
Thanks

And then?
After doing reset\calibration of battery circuit we put phone on the wall charger and wait until green LED.
Right?

In most cases, must to change the cable or adapter, or both. I had the same problem twice.
