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.

Phone suddenly switched off. Dead, not charging, orange led blinking.

Hello all,
I have a htc desire 820 single sim. I had absolutely no problems with baterry etc.. This phone has only 4 months - i didnt put it into water.
I have unlocked bootloader and rooted my phone 3 weeks ago but it was running with no problems. I didnt install any aggressive software that may brick the phone. I just wanted to get access to all files.
So two days ago in the evening i just installed Skype app and wanted to download a file sent by my friend then in the moment that i was downloading my phone suddenly went off - just like there was no batterry etc (i remember it was more than 30% of batterry). I couldn't turn it on - 0 react. I tried to charge him - the orange led is blinking with 1 sec frequency. I left this phone overnight and still nothing - now its 2nd day that its charging and still nothing. I doubt it was a virus becouse i recieved this file on other phone without any problems.
I tried:
-volume buttons - booting in loader = nothing
-plenty chargers, cables = nothin
-charging via pc usb = nothing
-phone is not detected in pc after i connect it (just orange led blinking)
My question is, what actually happened? What else could i do to try to unbrick my phone?
The day before it got bricked i accidently let it fall down on the ground but frim 40cm distance (i have a silicone cover around) = but i didnt notice anything after falldown.
Thank You for any advices.

I think it's battery problem. I had something similar with One X. You can try leave your phone plugged in to charger (try every micro-usb charger that you have in home) for a night. LED should turn green, if not I recommend send it to htc for battery change or to "professional service" in your city Good luck!

Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to bootloader.Telefon must be connected to kompyuteru

Im trying plenty chargers and cables at the moment - for now= 0 results @vuk1963 i tried your method but 0 react from the phone - just like before.. totally dead- just this god damn blinking orange led..
Edit:
WOW... my phone is alive!! All i did now was:
I tried charger from my galaxy core (same amperage like htc 820 = 1A) but i used original cable from my htc charger. The led was still blinking so i decided to "knock" the back panel (around the place where connector from batterry is), then i pressed vol+ and vol- and power button for around 20-30s, then i pressed vol- and power button for around 30s then i released everything, then i pressed power button for 10sec and my phone turned on!!! im so happy! my phone is still on warranty but i live abroad now so i need to send it to my country to start warranty procedure but no im free of this!
Thank You guys for pushing me to try once more the magical tricks with cables, chargers and buttons
Btw.
My batterry is now 100% = that means it was charging all the time?
i don't know what was that but i am happy that it work now.
Thank You guys!

The phone was overheating and it stopped!
Leaving it for a while, then the combination of buttons did the trick.
Great to hear.

Send it back to htc, mine had the same problem. There is no way they will find out u are unlocked or rooted since it wont start. The problem is the motherboard failed. I got mine back with the motherboard replaced.

htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4)

About six minths ago, my htc 820 had bricked.
When I connect the phone to wall charger or computer, it only responds blinking a orange LED.
At that time, I tried push a power button, volume - + power button and volume - + volume - + power button, but it failed.
A few days ago, I disassembled the phone cover, and I disconnect battery from the phone. I waited for a day, and I reconnect the battery to the phone. But.......... It didn't work.
Now, my htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4). My computer even cannot recognize it correctly. Is there anything I can do to revive the phone, please.

I tried as above. But I failed. I pressed vol+ + vol- + power button, and then released. Then I pressed vol- + power button. Then pressed power button as you quote. Was I wrong?
My htc 820 won't wake up.... and thank you for the reply.

no your case is different, showing up as Qualcomm HS-USB QDLoader 9008(COM4) means your phone has been hard bricked and I dont think there is any way to make it work again as far as I know, there is no fix for hard bricks except for some phones(not D820)
----
but if you connect charger and LED still turns on, there may be a way, take it to a repair store I guess

Thank you for your answer. I want to know what QDLoader 9008 means and you gave me a cool answer. I'll give up reviving htc 820. :crying: There are no htc service center in South Korea.
In the meantime, the phone has been connected to wall charger for 6 hours, but still orange LED blinks.
Something I am doubt about charging process, I found a charger and the phone became hotter. Why they are getting hotter?

My HTC 10 just died today :(

So my 10 just died today.. what happened was... it still has around 41% battery but I decided to change is already since I will be going out. after 30 minutes I checked the phone but it was turned off and not charging, led is turned off. I am using a Choetech quick charge 3.0 charger with original HTC type-C cable. I already tried some possible fix around the internet but none of them work. So I assumed this is a hardware issue caused by maybe an incompatible charger. Although I use this Choetech charger for over a month already without any issue whatsoever.
My question is.. Which part/s would be possibly damaged of using an incompatible charger? (battery, charging board?). HTC devices are no longer released in my country anymore so no HTC repair services are available. Sending it to country where I bought it for repair might take months so last option I'm thinking is to repair and replace defective parts myself.
Hope someone with HTC hardware expertise will help me...

Maybe you could only ask HTC about this issue, they could have an idea. But, for sure, you won't be able to make it repair with warranty as you used a non-htc charger.
Unfortunatelly, I really don't know about it.
As you had still 41% of charge, there is power in so rather sure the battery is down but what about the rest?? I hope someone can help you more

So it doesn't power on at all, even with holding the power button for 20 secs?
Download mode also?
I would definitely contact htc about getting it replace/repaired...a bit expensive of a device to not use its warranty...which has to be honored.
You used a QC3.0 compatible charger...that is the requirement; OEM is not the requirement.
Unless someone can prove a defective charger is the cause (it's not like OEM equipment can't be defective or break), it would be an assumption made in bad faith.

I will try to contact HTC Taiwan. Sure they can help but I am concern on how long the process would take to ship my device to them for repair and send it back to me.
just for info.. this is the charger I used > Choetech
And this cable I used in the office to connect my device to my computer > Choetech cable

Incorrect. There is no way for HTC to know what type of charger was used.

Yeah, I think that HTC should be a nice option. even if you don't send the phone back to them, they could give helpfull informations. And maybe, ask other users that live in your region if they already had to send a phone back to htc and see with them if the delay is acceptable. As HTC will be thet best for it for you to keep your warranty safe

Their service is actually very fast. The offer an option where they will send you a replacement phone right away and put a hold on your credit card and remove it once the device is in their hands. If you do not choose that option and send the phone in and wait for repairs (which i have done before) it took less than a week.

With the 10, try power + vol up + vol down. A bit different than on previous models. The capacitive keys will blink several times, then the phone will reboot. If you need to get to download mode (or bootloader which you can access from download mode), switch to power + vol down immediately after the phone shuts down to reboot.
I had to use this method myself twice today while testing a beta ROM and getting a black screen after the flash.

The capacitive buttons don't blink holding down all buttons (vol up and down plus power)? Crappy. It sounds like you've got a hard brick. After my response, I got black screen four more times and was able to get back running. Six times in total. If they are blinking, keep holding them down 'til reboot

No response at all. It's a hardware issue I think.
Already contacted HTC SEA (Singapore.) They just redirect me to their HTC TW counterpart as my device came from Taiwan. Unfortunately, after days of trying to chat, no response from them until now . Really disappointing!

No! The volume buttons are a rocker and if you hold both of them, you may break the button. There was a case review video that showed this happening (no idea which one; I've watched many).
You only need to press power + one of the volume keys (I don't remember which one, down I think...for download mode) to get the effect you described.
It worked when my phone was comatose from the PC BSODding during an RUU.

Incorrect, but I was too.
Vol up + down + power forces a reboot. I was responding after beers, and didn't realize/notice that he was trying to boot up from a powered down device. That's why I said as soon as it powers off to switch to power + vol down.
It won't break the buttons. It's the way that HTC has made the 10 to force reboot. I don't think they would do that if it would break the volume rocker.
Power + vol down from a powered off state should boot to download mode in the situation he is having.

Tell htc to update their documentation then:

HTC 10 not responding?
If HTC 10 does not respond when you touch the screen or press the buttons, you can still restart it.
Press and hold the POWER and VOLUME DOWN buttons for at least 12 seconds. HTC 10 then restarts.

And it works. Thanks for that.
When I tried this a few weeks ago when having issues, my phone didn't respond to it. I had to ask in the Venom Beta Hangouts chat what was up. I was told press both vol up and vol down + power, and that did work for me so I stuck with it. Maybe it was a problem with the situation I was in at the time.

Thanks for all your suggestions.. but none of them work.. the device does not respond..

Daughters phone is completely dead, will not switch on. Please help

I have had it plugged in all night, and tried the following ;
Hold power for 1 minute
Hold power and volume up for one minute
Hold power and volume down for one minute
Hold all 3 buttons for one minute
None of these worked.
I have plugged it into a PC but there is no connection.
Is there anything else I can do?
*EDIT* Fixed it! https://forum.xda-developers.com/showpost.php?p=83649851&postcount=7

Its dead phone. What do you want some magic to turn it on? If it dosnt want to turn it on its dead phone and you cant do anything about it.

You might be right, but in the 20 years of owning mobile phones I have never had one that simply "died" before. I've ordered a new charge port as I think it might be to blame.

Pressing pwr + volume down or volume up won't turn on device.
You're not saying if device can enter to recovery nor fastboot or If your device is unlocked or not or if you have some screen as the logo or if you have some vibration, some led blinking, or if you let it charging with screen on (it must be screen burning) or if device was off while charging...

The phone has no sign of life. No led, no screen on. Nothing.

Well, there is not much you can do here, it could be a damage at the hardware level, probably in the port charger or at emmc/motherboard.
Also the overcharging or the kernel panic produced for some overheating can make that device won't boot.
The only you should try at software level is this https://c.mi.com/thread-1479882-1-0.html

I fixed it! After replacing the charging port it still didn't work.
However I read somewhere that disconnecting then reconnecting the battery connector inside the phone would work so I tried that and it worked.
Phone back working fully.
