I have an HTC One M8 AT&T unlocked, rooted, ARHD 34 installed.
The other day I used the phone until about 9 AM and when I pulled it out of my pocket the very next time there was no response. I tried Volume Up + Power, Volume Down + Power, and Volume UP +Volume Down + Power no response. Tried all three again with power cord attached and still nothing. finally after about the 20th try with power attached I got a charge light to light for about a full second but then it goes off immediately. This now happens every time I plug it in. sometimes it's a full second of the charge light others it just flashes on then off immediately.
I need some help, because I am not sure what is happening and I don't want to just tear it apart and throw parts at it. I am thinking the battery took a crap on me but I need someone else to confirm my suspicions.

Have you tried using a different charger? You can also check if there is a damage on you charging port.
Try using your charger to a different phone and if it works then there is a problem with your charging port. You may want try plugging in the charger to your M8 and try to move the cable near the port. If it works, then you must charge your phone in a specific position. The best thing to do is call HTC to process RMA.

Need help /advice please
Im on M9 rooted,s-off, viperone 3.5 rom, supercid, firmware 2.10.401.xx and twrp 3.0.0.0. all fine beforehand.
I was planning to do firmware upgrade, so thought i better check the laptop connections first.( So I haven't done any firmware upgrade or rom change yet.) but..
heres what happened
(note - all was working fine last week, recovery, adb, reboot function were all ok.)
- Yesterday i connected my phone to laptop and my laptop suddenly was not detecting the phone (!). strange. it worked last week. (but the laptop was still able to charge the phone then). Tried different cables same thing. strange.
-so i thought its been ages since a power down. probably needs a proper shutdown and then clean reboot right?
-i shutdown the device using the power button. (I might have accidentally pressed the power button too long and forced a shut down - cant recall )
-but the device shutdown like normal and then just would not reboot. nothing. no charge light even when connected to charger now.
-I tried hard reset press all three (vol and power) buttons for 30seconds (up to 1minute) - nothing. phone still "black screen of death". wont boot. (tried vol up+power or vol down + power all no boot no nothing.) Never happened before. No idea what happened. Any ideas?
Any advice much appreciated
Try holding all three buttons for a couple of minutes while it's plugged into the charger.
If that doesn't work, leave it plugged in overnight. HTC phones can have these weird power issues where the phone appears to die, then comes back to life the next day.

OK I will try that. My battery was 90% charged before it died. but will try your suggestion and get back to you. hopefully my M9 is not irrecoverable....
{edit}[Update]
When I plugged into charger the charge light does not go on.
but i tried hold all three buttons while in charger, the charge light did begin blinking on and off times, but no reboot.
(i tried that over 10 times, holding upto 3 or 4 mintues till my fingers turned white, sadly no reboot.)
So I left it plugged into charger overnight but same this morning.
Any idea what it could be? I was rooted, S-off and unlocked bootloader so my warranty is history anyway.
Appreciate any ideas/advice. tia.
Having power issues as well..starting to think this m9 is a piece of junk..3 of my USB chargers stopped working on my m9 (they worked before)..one charges on and off very slowly.
ya my M9 just died and still would not boot. So strange, because it was almost all was fine beforehand. it was just it suddenly could not link to my laptop. and after a power down just died.
So after hours and hours of holding all three buttons while charging, not able to boot for days, and leaving charged for nights and no boot...I gave up. Took my phone to HTC service. They said it might take a month and I have no warranty. not happy with this at all and very confused. My guess is it could be the Power IC or some capacitor that just died. No idea. Makes me begin question quality of the M9. I saw a few guys on youtube comments say same thing. Their M9 after shut down would'nt reboot. So its not just me at least.
I saw this same thing happen on the M7. Some weird power/battery gremlins. Annoying they haven't fixed it.
after 5 months of my phone in and out of different HTC services they could not fix my phone power issue and seems they gave up and
replaced with new phone.
so almost 5 months I had no M9. . the power issue really disappointed me.
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.
Hi Guys,
Strange problem here.
My M8 does not respond to any button combination at all.
But when I plug in the charger, the red LED Light comes up, the battery icon comes on the screen, the red LED gets brighter, and then everything goes black and the process starts again.
I was wondering if any of you guys experienced this, or know what this is? It suddenly happened.
I was thinking of a problem with the battery, but not sure?
M8 is running the latest insertcoin.
Charge the phone for several hours (overnight) on wall charger (not connected to computer). Then hold power + vol up button for a minute or longer, and see if any change (even if it's just the HTC logo screen). Folks often don't realize you need to hold the buttons what long in certain "stuck" situations, including battery drained/power off. That includes myself, I thought my M8 was bricked some months ago, as I was simply not holding the buttons long enough.

Thanks for the reply. Tried that already, but will try again later today. If there are more suggestions, always welcome.
Hey! Few days ago my M8 has stopped working. Just picked up the phone in the morning and it was dead (didn't charge it at night). Only charging diode glows orange when the charger is plugged in.
I've checked battery voltage with multimeter and it was 4,04V. Tried to hold power button with every combination with VOL+, VOL- and still nothing... Charging icon doesn't appear on screen. I've also checked every possible connection inside and everything is OK. Do you have any suggest? I really want to rescue it cuz it's the best audio recorder I've ever had Please help:crying:
Try holding just power button for a minute or so. Or try power+vol up for a minute.
Most folks don't realize you have to hold the button for so long, in this situation (battery ran down).

Try leaving it on the wall charger a few hours, and try again. Or try it with the charger connected.
I know you already tested the battery voltage as being good. But folks have had luck trying the various things I mentioned above. It's all you can do short of replacing the battery (which may not be the issue).
my device always red light is blinking. not open
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.
