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.

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.

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:

[Q] HOX overheat

Hey guys, I download a couple of launchers to try out (in case it matters) and then left my phone on the charger. About 20 minutes later I went to check on my HOX and the power button was unresponsive! I held it down for a few seconds and the bottom 3 touch-buttons flashed a couple of times but the screen was still blank. I then unplugged the phone and held down the power button again, the touch buttons once again flashed a couple of times and then all of a sudden HTC One X screen showed up and the phone restarted. I now have the phone plugged and shut down. Any ideas on what just happened to my phone?? I'm really worried as this is my second HOX and my replacement period has passed long ago.

The phone was hot during the whole process (sorry, I forgot to mention it). And if it's not overheating what is it? Oh another detail I forgot to mention is that when i unplugged the phone, the red led stayed on until the phone rebooted.

It boots up fine now. It started getting hot while i was trying out the different launchers but I thought it was because I was using it, so I decided to let it charge and to cool off. 20 minutes later the phone was unresponsive and even hotter, I held down the power button and the touch buttons flashed a couple of times, unplugged the phone but the red LED was still on, and finally I held down the power button again and the HOX Screen appeared and the phone restarted. That's about it, the phone is cool now and charging just fine, but I'm worried because I doubt that the phone would overheat just by switching launchers, I'm afraid that it could be something bad.

It probably just got stuck calculating something, sending it into overheat, preventing it from charging until it ran out of charge.
I'd worry about it only if it continues, sounds like a software bug.

[Q] Phone doesn't turn on 3 icons blink

So I replacef the LCD screen on my p930. re assembled everything and it does not turn on. i don't feel that click when i hold the power button, If i plug the phone into a AC charger and hold the power button i get 3 blinking keys on the phone.I can't even get the phone to vibrate like when it normally powers on. Anyone have any ideas of what this could be?

Try to open it up again and double check your work, Something might have come loose.
Before you changed the screen was it working properly? Why did the screen break? Was it dropped?

The battery is beyond dead. Let the phone charge for a day, if it hasn't come on by then look at all connections u touched. Last case is try another battery you know works.

if you didn't connect the new lcd properly its not going to come on, also the new one might be defective, did you get it on ebay?
did you make sure you have the right screen? taking the phone apart and putting it back togethere there is alot you can miss or go wrong, when i did mine i was so careful it took me multiple hours, i took my time with every detail these things are worth 400-700 depending on who you ask either way you can't rush it

This. Try this before you go tearing your phone all apart just to find that everything is put together correctly.
Plug it in and leave it plugged in for 10-15 at the minimum before you try using it. If the phone shuts itself down due to the battery running completely down, it will be completely unresponsive to anything unless plugged in; at which point it will only flash the bottom keys when you try to turn it on. Once it gets a little bit of charge to it, it should boot right up.

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.

[Q] HTC One X is on a rebooting loop. How can I stop it?

My HTC One X is on a rebooting loop which I cannot stop. I cannot switch the phone on and it only stops rebooting when I allow the battery to drain. Once plugged into the mains it begins rebooting again. The rebooting only goes as far as the quietly brilliant screen then goes blank and a few seconds later fires up again to the same stage and again goes blank.
I know little about phones so any suggestion please keep simple? Thanks

will it help to reboot if the battery had more power?

when it's off charge the menu appears which has factory reset and reboot but it's not easy to do this as battery level is so low. I think the battery is on its last legs as before this problem happened the phone had been switching off during use and the battery level went critical at 1% power even though it was not being used. and it was recently charged up.
Is it possible to get a new battery for an HTC one X? I somehow doubt it...I may need to replace the whole thing.
Thanks for your help. I'll keep trying off charge once I charge it up a bit but I'm growing weary.

If you let it reboot continuously and hook it up to the pc it should charge the battery up real slowly. That's a chance you can try. You can also put in a hox+ battery.

Hi again
Good to know a change of battery is possible. I've given up now....My other half is gonna take the phone to a IT/gizmo wizard bloke who does repairs on gizmos and maybe he can fix it. The Vodafone guy had little idea but we were told something about a flash that might give it enough of a boost to enable a fastboot to work???
If that doesn't work I'll stick to my bonny wee Desire C for the moment.
Thanks for your help. I'll post the outcome of the rejuvenation or demise of my HTC One X.

Has your HTC One X gotten wet at all recently? This behaviour occurred in mine when the phone became wet. The problem was the Power Flex Cable, which can be replaced very cheaply.

What do you mean by power flex cable?
The top of the phone may have dipped into the bath...bad idea to google whilst bathing especially when one is tired.

Yep... it's going to be your Power Flex Cable. It's a small ribbon that goes from the power button down to the top of the motherboard. There are small circuits on it which get damaged when they come into contact with water. It's fairly easily replaceable. I wrote a post a while ago which should help you out if you want to give a manual fix a go:
