[Q] Turned it off...Won't turn back on.

I did a soft shutdown and now it won't turn on. No response to Vol UP + Vol DOWN + Power. Nothing but black. Its connected to power and was at 80% when I shutdown. USB debugging was enabled. Any hints? Thanks, -RP

Ugh, I had to hold power button for 30 seconds. Its really excessive. Delete this please. Thanks.

funny thing is the old nexus 7 had the same issues

I received mine today and it wouldn't turn on at all. All I got was a flashing white light after holding the button to turn it on so knowing that the same thing was common on the previous generation N7 I tried the 30 second trick with no success so I figured I'd share my experience.
Turns out my battery was at 0% out of the box. It was so dead I had to do the following to actually get it to start charging unfortunately:
1. Open it, I followed the guide @ ifixit: http://www.ifixit.com/Teardown/Nexus+7+2nd+Generation+Teardown/16072/1
Note: The plastic bezel surrounding the screen is incredibly soft plastic I just learned. Even using plastic pry tools I ended up leaving marks the plastic, despite being extremely careful.
2. Disconnect the battery (follow the guide above)
3. Press the power button and hold down for 10 seconds, but don't release yet.
4. Using the supplied AC adapter, apply the power and continue holding for another 10 seconds.
5. Reconnect the battery while the AC adapter is plugged in​This should get you to the point where you at least see the battery charge icon on the LCD. I waited another 30 minutes before moving on and powering the device on. I intend to leave it charging to 100% before I do anything else with it.

I remember on some older devices I've had when they got into 0% state, they didn't want to take a charge from a high power charger and I needed to switch to 500ma USB 1.1/2.0 slot on PC and let it sit a while before it would trickle in enough charge to get some life.
After that it would take charge from any source again.

lol - this happened to me too. Except double whammy - as soon as it was charged enough to turn on, it wanted to do the system update and wasn't charged enough to do that. Back to the USB it went!

Well I got my replacement for the one with the dead pixels, it started up fine and I even configured just to check it had no dead pixels. I had to step away for a few minutes and it was off, completely dead. Tried ever variation of tricks and I get nothing, no white LED, no charge indicator, nothing.
I think I'm sending both the replacement and the original back for a refund, this is just unacceptable at this point.

I bought one but returned it after 3-4 days. Mine was fully powered and I would go through the shutdown procedure. The device would power off. Then I tried to turn it back on. It would not work. I held it down for several variations of time: pushed it quickly, help the power button in for 10 sec, 15 sec, 30 sec... I found that when I connected the device to power through the usb the screen would show 100% charge right away. I would then hit the power button and it would turn on fine. I immediately unplugged the device and everything was fine. i powered it down again and repeated this process 2-3 more times before I said the heck with it. Anyone else know of this issue or did I just have some crazy unit?

Wont turn on!

Hello!
I dropped my LGOG E975 and the screen has cracked. The upper half would still work. But i could not turn the phone off. So i let the battery run dry. When i came back from vacation, approx. a month after, i sent it in to change the screen. It got changed, but now it has another problem:
It wont turn on! At the store they said they could not get the phone to boot. I took it to a charger and while holding the volumebuttons it showed the LG logo for a second, then blinked red a couple of times. This happend twice. Now if i hold the power button for 15 seconds and plug it in, it will quickly blink a red light.
What to do? I suspect it's something with the software.
FIY i unlocket the bootloader, rooted and installed a recovery. Dont remember which one tho'.

Update:
I can now enter fastboot or download mode. But the phone wont be found by kdz. flashers.

Try to access recovery from the fastboot screen, pushing 2 times volume down then power.

The phone turn black, blink red once and thats it.

As a sidenote, i can only put it in fastboot or downloadmode after i hold the powerbutton a while before plugging it in. Else the red LED wont blink.

I have no idea then
Have you tried to put it in fastboot without plugging it in? Volume down + Power button when the phone is off.

No response from the phone. Can it be a batteryproblem since the red LED flashes shortly when plugged in and entering fastboot/download mode or trying to open the recovery?

Maybe. Leave it charging for a while and try again.
My father always lets his phone die out of battery and he leaves it off for a while like that. When trying to power it back on, or when plugging it to the charger, the led flashes just like you described. It's not an OG, but it may be something similar what's happening to you, since you said you left it for quite some time turned off.

Okay, i will try to leave it over night. It will sit in the charger for 6 hours before my next check.

Try to upgrade/recovery with LG support tool in download mode
Sent from my LG-E977 using xda premium

It would still not turn on. Tried multiple chargers and leaving the phone in for a long time. I got a new battery on the way.

Sometimes it helps to hold the power button a bit longer.

I held the powerbutton down for multiple minutes. Still no response. I ordered a new battery from Ebay. Hoping this would fix the issue. The battery have a expected delivery this week. Will update the thread with the results.

Hope it works :good:

I tried everything. Really. Every possible combination of buttons, chargers and cables. The phone would only give a response when plugging it in. So i expect it to be a charging problem with the current battery.

what was the outcome with the new battery?
im an currently experiencing an issue that sounds much the same as this, difference is that i was using the teenybin software and the HS shutdown halfway through the update, and now will not do a thing other than blink the RED LED when i hold the power button down whilst pugged into charger
also to mention, the battery life on the HS prior to this was reasonable..

HTC M8 Doesn't Boot, Red LED Flashing, Not Charging

HTC M8 doesn't boot red LED flashing not charging
Hi,
I have big problems with my HTC M8. It is 11 month old.
I is rooted, has 4.16.401.10 firmware, Android Revolution HD 43.0 and
S-off SunShine.
In the evening I put it on the charger with 61% battery left. The next morning it didn't start up anymore and the red LED was flashing.
The battery didn't charge and so long it doesn't boot up at all, I can't connect it to the PC. It is only shows the big battery sign when I connect it to the charger which disappears some seconds later.
I didn't want to send it to HTC for guarantee, because I couldn't put on stock software.
My lokal handy-doctor changed the battery... nothing!
He changed the USB connection... nothing.
The red LED keeps flashing, the battery doesn't charge, it only becomes warm, I cannot turn it on. I have tried to press the power-volume+ -volume- buttons, nothing.
I think HTC will charge me, if I sent it for guarantee, or does anyone have other experience?
What should I do? Any idea?

Try holding the power and vol up for a long time, maybe a minute or so, and see if there is any change.

That was one of the first things which I tried. It has no effect.

Try power+vol up, and also power+vol down, with and without wall charger connected. I've seen a couple people have luck with that. Otherwise, if it still won't work, its pretty much bricked.
Especially since you've already had a new battery installed, it may be a problem on the mainboard.

Since you've had a 3rd party take apart the phone, replace the battery, and replace the USB port, your warranty is void.

I did that so many times. It doesn't help. I think its a hardware problem.

As you tried all the things I suggested with no luck, I agree its probably a hardware problem.
This would have been justifiably covered under warranty, since its a hardware problem. And since the screen doesn't come on, they wouldn't have known it was ever bootloader unlocked, custom ROM, etc.
But now that you've had a repair shop open it, it will be obvious to HTC the phone has been opened and they will probably charge you for repair.

Replace the old battery and trash the phone. Send it in under "UH OH Protection"

From what I'm seeing, the M8 is only eligible if purchased after March, 2015 (which the OP did not):

This isn't the "same problem" unless you (like the OP) took it to a repair shop, had them replace the battery and then the USB port? I doubt it.
Posting "I have the same problem" is just lazy, and doesn't give us the proper info for anyone to properly help.
How did this condition come about, did you just find the phone in this condition? Or were you flashing anything or any other actions to cause this condition?
Plug the wall charger (not connected to computer) overnight. Then hold the power and vol up buttons for a minute or 2, and see if there is any change.
Also try a different charger and cable.

Ok, sorry for the lazy answer.
So, yesterday the phone works fine, when i go to sleep.
Today, the alarm clock sounds, I woke up, and when i take the phone, the screen is black. Therefore, it didn't work.
I used another charger and cables, but don't work.
The S.O is sense stock, only had custom recovery, but I never used.
If i plug it to the computer, isn't recognized.
Maybe, you can know any solution for that?
A lot of times, I try, with power + vol up and power + vol down, for around 20 seconds.

Thanks for all help, but my phone didn't change the red flashing.
I think I have to accept that my phone died the red flashing death. RIP

I specifically said to hold power + vol up for 1 to 2 minutes. 20 seconds isn't enough in some conditions.

Nothing shows up in Device Manager (if you are using PC)? Such as with an exclamation point by it?
No message about Qualcomm drivers?

I try again yesterday, hold the 3 buttons of 1-2 minutes. After that, hold power and vol + for the same time and any signals.
If i use my PC, doesn't recognize, didn't install drivers, or something else.

HTC One M8 not turning on or charging

Installed Viper Rom 5.0.2 running normally for around a month.
I plugged the phone as usual for charging in night at around 15% battery level.
In morning phone was dead.
Left it charging for a while but unable to switch it back on.
No led comes up while charging.
Did lot of research online and Tried all methods like pressing Power + Up or Power + Down or Power + Up + Down for a while for switching the phone on.
But no response from the phone
Also when I put in the micro-usb socket (when attached to charger or computer) while pressing power + volume up buttons the led flash orange for a second.
Connected with PC shows up as QHSUSB_BULK under device manager.
Please help in reviving my phone.
Thanks

How long is "a while"? Let it charge for several hours (overnight) and try another cable and charger, in case the first one is broken.
Then try to hold power+vol up (or power+vol up+vol down)for a minute or more.
The fact it flashed an LED at all is a good sign. A true brick usually has not LED response.

OoohhhI KNOW...
****...i hope i am doing this rite...
Anyway...what you do is so the volume up , power , and the return buttons all at one time...until it turns on....leave alone so it can reboot.
It should be good to go...
Seriously i found if you do this to any device acting unusual...even for
volume issues...check your devices cpu..if it runs hot a lot,
i found this to be related somehow in the htc..
Call me c r a zy
You have to do it longer...if you have no reply...dude this works ..
Or your phone is Effingham dead dude.....

Naa nothing worked...
led comes on (just for a second) when I keep pressing the power button and put in the cable to the phone.
Also I noted that when I plug in the cable a bit further than the exact slot of charging point led stays for 4-5 second then goes off.
very frustrating it has become...

HTC M8 Completely Dead
Finally I sent the M8 for hardware check and repair.
But unfortunately it was completely dead for no reason.
I left the hope and bought a new phone....

NO Solution at last...
HTC should help me out here...
There phone is completely dead... in just less than 2 years and that to with normal usage (without extreme usage)
I hope someone takes the message to htc for the problems the customers are facing from there devices..
They should just replace such devices with new one for satisfying the customers who had believed in there devices and paid premium amount for the same.

HTC One M8 Totally Dead (No Access to Boot Menu)

Hello everyone,
Thanks for always helping in times of trouble.
I was using my HTC one m8 normally, playing with facebook. The battery was on 82%. Suddenly the screen frooze then the whole phone went dead completely. Not even a screen backlight. I tried to power it up. It didn't work. It had original ROM, with no modifications whatsoever.
Here is what I did so far, without any results.
- Charge it for few days with original charger and cable directly from the wall. No sign of life. No charging flashing light.
- Charge it with another cable. Nothing.
- Tried to access the boot menu to wipe everything clean. Pressed power+volume down. Nothing. Dead Screen.
- Pressed power +volume up. Nothing. Dead Screen.
Pressed power + both volume buttons. Nothing. Dead Screen.
- Connect it to the computer with updated HTC Suite. The computer said no phone connected.
I using a crappy old iphone now, but would love to get this HTC back to life. Any past experience with similar situation?
Any tips to resuscitate the dead phone?
Thanks a lot for your help.

In some "stuck" or powered off conditions, you may need to hold the button combos for a minute or so, before it actually reboots. So make sure you are holding them long enough.
But the fact there isn't even a charge LED, is concerning. Even in brick conditions, you should get at least an orange/red LED (maybe blinking? Can't remember). Makes me think the battery is bad.
Also play around with the button combos with the charger connected. I've seen a couple folks have luck with this, when nothing else seemed to work.
Additionally, the phone won't connect to PC when powered down; even on a working phone. You at least need to get to a bootloader screen to connect to a PC in any way.

I tried to do as instructed but it didn't work. I held the buttons on different combinations for at least two minutes but the phone stayed dead.
The only changed I noticed is one point I saw a very weak charging flash then it quickly disappeared and never came up again even when I repeated the process. Does this say anything?

Hard to know if this means anything specific. The symptoms don't look good. Might be bad battery, or other hardware failure.
