M8 Dead- No Response at all. - One (M8) Q&A, Help & Troubleshooting

Hi,
While using my M8 all of a sudden the screen froze and after few secs the phone went blank.
Since then there is no response at all, only LED blinks(Red for few secs) sometimes when connected to a power source.
I've tried all the Power and Vol Button combos, nothing seems to work .
There is no vibration too.
When connected to PC it says"Qualcomm H-USB".
The phone is rooted.
Any suggestions or workarounds???
Thanks in advance!
Regards.

Try leaving the phone on a wall charger for several hours. Then try holding power+vol up for a minute or more (folks often don't realize they need to hold the button combo for so long in some conditions). Try it with and without the charger connected.
If still no response from the phone, you my have a hardware failure. Its getting more common as this phone ages.

[Q] Desire won't turn on after market crashed

Hi there!
I have got a really strange problem with my desire. Here is what happened:
I opened the market app whilst using mobile internet. The app froze on the loading screen and the phone was unresponsive.
I pulled the battery and powered on again. All seemed fine.
I opened the market again and the exact same thing happened, only this time I can't turn the phone back on.
I have tried pulling the battery. Tried plugging the phone into a charger without the battery then reinserting the battery. Tried charging the battery until the led went green, still no luck.
I had plenty of battery when this happened.
When the phone is on charge, when you press the power button, the led goes out, but the phone does not turn on.
Does anyone know what this might be? or how I can turn my phone on again?
Thanks all!
Bump, does anybody have any idea?
The only idea I have is a hard factory reset:
Try to start phone with pressed volume down and power button, navigate with volume button to "clear storage" and enter with power button.

Thanks for the ideas guys. I actually can't power on the device at all. Can't boot into recovery, can't do anything as far as I can tell.
Any other ideas?

What the hell are you doing to ur desire?
Try removing battery for a minute, then re insert it
Then press volume down and without release it, press also power button and wait 5 seconds with both pressed to see if it boots into bootloader and go into recovery too

I removed the charger before putting the battery in. I saw someone recommend it on another forum with a similar problem.
I have tried to get into recovery after leaving the battery out for 12 hours, after charging the phone until the led was green, it seems I've tried everything to get this to work but nothing.
I'm really annoyed as well because I'm 2 weeks out of warranty. It just seems so odd that a software crash could cause all this.
Anybody else got any ideas?
what happens when you press.. volume down and power.. can you see the hboot screen.. is your phone recognised in ur pc?

Absolutely nothing. Totally blank screen, no vibrate nothing. Phone is not recognised by pc. The only things that happen are the following:
When plugged into the charger the orange led comes on, and eventually turns green.
When plugged in, if I press the power button the led turns off, but nothing else happens.
I'm totally at a loss. I called HTC and am sending it in for warranty repair. They said they have extended the warranty to 2 years which is a bit of a turn up for the books, so hopefully they will fix it for free and not charge me for it
Try this:
Boot into hboot
Count (slowly) to 20
Then press the power button once
Connect the usb
Start command prompt
Type "fastboot devices"
For this to work you need to install Android SDK see here http://wiki.cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK
If you get anything than somebody can help you. I read somewhere about this issue but I can't find it anymore.

[Q] [ION] Please help with possible hard brick, I've read other threads

Hi, today while I was browsing on Firefox, the app closed by itself and the home screen got distorted (the wallpaper got black and some icons started to show up in the background). Since it has happened before, twice in the last week, I tried to reset the phone. However this time the phone did not turn on. I put it in the charger and the LED is also not turning on. I've had it plugged in for about 9 hours now and the LED is still off and the phone is not even getting warm, like it usually does when it's charging. The charger is also not warming up, and when I tried to connect the phone to the computer USB port, Windows doesn't report any power consumption.
I've read some threads about bricking, so I know people mention longer times to get the LED turn red, but is it normal that it doesn't warm up and doesn't suck any power from a USB port?
For anyone familiar with AT&T operations, if I sent it as warranty replacement, would they bother running diagnostics? I have it with LT28i .68 firmware, rooted and with CWM.
Also, is there a way to retrieve the data from the internal SD card? I tried connecting it to the computer and nothing happened. Nothing happens when I press either volume button + power button. An nothing happens when I connect it to the computer pressing either volume button.
Any help will be much appreciated.
Have you tried the Hard reset?
Holding Power Button and Volume button together for at-least 3-5 seconds and you would feel 3 vibration.

I tried that too, the phone also doesn't respond.
Does ION has removable battery? If yes try to remove it for a while.
If not. Then try the buttons combo with the phone connect to charger...

The Ion doesn't have a removable battery. I already tried all combinations of power+volume buttons, while disconnected and connected to the charger, and nothing. Maybe the battery somehow got disconnected internally, I don't know if that's even possible.
I've called AT&T, they'll send another warranty replacement, the second replacement I get. Hopefully this one will last enough at least for an early renewal.
I don't know if AT&T still does this but back when I was in the states last year I had them give me an early upgrade because two of the handsets they gave me were faulty (original and one replacement). Try talking to CS Reps sometimes it pays off. You might be able to get an early upgrade if you tell them how this can't keep happening you have important data blah blah blah.
Anyways good luck!

Phone just stopped turning on..

well...this kinda ruined my night yesterday...I went to a concert yesterday around 8 and my phone had 70% and I was checking facebook or something like that and without no notification or warning it froze and turned off on me. I figured it was a normal freeze..and I attempted to turn it back on and nothing happened. Went to my car to try to charge it and nothing. Not even a charging light. A day has passed after the concert was over (could not take pictures, thanks htc..) and now the "dead battery symbol" comes up and the orange light keeps BLINKING..to my understanding it means that it is not charging? What could it be..anybody could help me out .maybe a soft reset? no charging it for a couple of minutes?
Anything would help. Thanks
Try pressing and holding power and volume up?
I'm sure you've already tried that, but can you confirm that you have left it plugged in atleast for 5 hours continuously after this happened.

And hold the power and volume buttons down in a well lit environment, there's a "pocket check".
You can also try by hold the power and volume buttons UP
Thanks for the replies , i have tried those opctions. Holding the power and volume UP and thencanother try wih the DOWN the with both. It just blinks orange now. I just woke up and plugged it in again, am going to work and going to leave it like that, hopefully that does the trick. Should i call htc ? It hasnt even been a month since the phones came out.. I did not do anything to "kill" the battery
Ofcourse you may call Htc.
the same happened to me now.did u find a solution?????

Get flashtool and drivers plug phone into it and see if flashtool detects anything on it. If that don't detect it unplug.
Hold the up and down vol button and press power button and see if it vibrates or anything. If still nothing then get a t6 or t8 screw driver remove the back of it and remove the battery and get a ohmz meter on it and test the battery or connect to a battery tester. Sounds like battery dead on it.

[Q] Galaxy Tab S - LED Flashing - Won't turn on

Hi, was wondering if anyone else has/had similar issues?
Got the Galaxy Tab S today and was spending time setting it up. Connected to the PC and charge was at about 57%. Suddenly the window displaying tablet contents on the PC disappeared and the screen went black.
The power button didn't turn the screen back on. I held it down, thinking that it required a hard reset but nothing happened. I disconnected the tablet from my pc and went to use it's dedicated charger. The battery icon came up, stating it was 57% charge, and shortly after the LED light on the back of the tablet started flashing rapidly. I quickly took out the cable.
I've tried holding down the home key, volume down, and power button and nothing happens. I then tried the same and having a finger on the screen. Then I repeated the process again with the cable connected to the charger, and then computer.
No matter what I try, the device won't turn on and the LED keeps flashing repeatedly when connected with usb charging cable. I also tried using another cable.
I'm thinking of phoning up where I got it from tomorrow and asking for a replacement, unless there's something I'm missing here?
Any thoughts would be great, thanks.
My guess would be, you are not pressing the buttons correctly.

That doesn't work either. The only response I get from the tablet is by plugging in the charging cable and then it goes on to display an epileptic inducing light show with the LED constantly flashing on and off

Never seen this problem before. Could be a bad partition making it not boot. Replacement may be your answer as its better to get a new one and be safe.

I've used various tablets before and never encountered any of them not booting at all. The led flashing business is very weird. I'll phone up the store I got it from and ask if I can get a replacement.
Thanks for the responses
