Hard bricked HTC one M8 - One (M8) Q&A, Help & Troubleshooting

So it has been 2 years since my M8 got hard bricked, however staying home during this quarantine got me thinking if i could try and fix it or not, so 2 years ago
i took my M8 out of my pocket it was not responding and slow so i restarted it and since them all my phone shows is a black screen, when i try to charge it the battery icon doesn't appear still the same black screen, just for a brief second after plugging it to charge the orange light up there flickers and then nothing more, when i connect it to the pc it's recognized as qualcomm hs-usb.
My M8 was with unlocked bootloader, but S-ON, had TWRP installed on it.

Maybe you can replace a new battery, which will give a hope.

Exactly the same issue here, but tried a new battery, no go. Have you managed to find anything since last April ?

When the brown light blinks and doesn't turn on it usually means the battery is too low to turn on the phone to display that its charging, normally it takes a few seconds or minutes depending on your charger, if it does turn on in a few minutes in my experience it means your battery is dead.
Another trick I was told about is holding the power and volume down button for 15secs while plugged in then hold the power button for 10secs.

Any chance you could confirm that when plugged in to the pc it's recognized as qualcomm hs-usb. I got a feeling the bootloader got creamed, i believe it should be showing up as a HTC something...

Have you tried to leave it in the charger and see if the blinking brown light turns green indicating full charge, alteast that way you can rule the battery out as the problem.
From the little googling this is the best answer I could find
Qualcomm HS-USB QDLoader 9008 is all that is left from my M8

HTC One M8 Hard Bricked - help

The phone won't boot at all, I've tried all the volume+power button combinations possible, not a single response/vibration. I installed the htc sync/drivers and it's not recognized on my pc, doesn't appear in device manager or adb devices. The power led turns on when I plug it in at least.
Backstory as you'd ask how someone could manage this: I was running a mostly stock 4.4.4 rom for the past month, no problems here. Decided to upgrade tothis 6.0 rom (MRA58K.H11), opted for some tweaks in aroma, nothing too special,
it ran with no problems for the evening. Today the alarm ringed at 9am, I disabled it, woke up at ~11am and here we are, black screen.
I was running TWRP and had no problems with 6.0 roms in the past.
Does the charging LED come on, and stay on? What color LED?
Try charging for several hours (overnight) then hold power+vol up, or holding just power (for a minute or so) with and without the charger connected.
The red led stays on if it's plugged in, which it was for most of the day. Other than that there's 0 feedback from the phone, black screen, all the button combinations do nothing, not recognized on any pc, etc.
I'll take it to warranty and hope they don't care about the unlocked bootloader and stuff.

Orange light blinking and phone won't turn on?
Hi guys give this a try next time you're phone has a orange blinking light. Especially for those phones that have a non removable Battery in there phones like htc 820 or an iPhone. Ok so unplug your phone press the power button 10 times at 1 second intervals to discharge it, then hold the power button for 16-30 seconds until it turns on. Then plug it up to the charger to properly charge even if it says it's charged. Hope that helps you guys out.

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.
Hii...I'm facing exactly same problem...Did you fix it?
My phone goes to bootloop everytime I start it. HBOOT and Fastboot are working fine although!

January 2017 patch bricked my Pixel XL 128GB?!

Hello everybody,
2 days ago, my Google Pixel XL received the January patch and downloaded it. It installed the first step flawlessly, but the second phase took a lot of time (the progress bar was staying around 50% for at least 60 minutes). Since I was not watching my phone during the rest of the process, I cannot say precisely what happened, but as I wanted to look how far the progress bar is, the phone did not respond anymore.
here is a summary of the situation:
- it is the pixel XL with 128GB of memory directly bought on the Google store
- the battery was fully charged before the update began, an it was approximately around 85% as I looked at the progress bar for the last time
- the phone was not hot during or after the update
- the screen is now black and does not display anything (I have tried everything I thought about: it is definitely black and nothing happens anymore, even when plugged for charging, or when connected to a PC (the USB communication with the PC is not building up anymore))
- the phone react only when the power button is maintained pressed for several seconds: it vibrates briefly, but nothing more happens
- the phone was never rooted, there was no "unknown sources" app installed (I had Cerberus installed but have uninstalled it 2 days before the Android patch was installed), and the USB debugging is not activated
- I called the Google support and they immediately proposed to ship a replacement device (they did not ask me to do some tries)
I have tried to discharge the battery by maintaining the power-on button pressed during hours: the red led then turns on when the charger is plugged in, but the screen stays black.
If somebody has an idea of a test I could make, I would appreciate the held.
Thanks a lot in advance for your suggestions.
Best regards
Vincent
Have you held power and volume down for 14 seconds?

How long have you had it plugged in? It sounds like the battery is empty.
Try to leave it on the charger for a couple of hours.
If it does not boot by pressing the power button, you can try to boot bootloader by pressing volume down and power at the same time.
The battery has been fully charged, so I am pretty sure that it is not the battery (the phone has been plugged in for more than 12 hours to recharge it).
I have also tried every button combination that I know and that I found on the web: there is nothing else than a short vibration when the power button is pressed, but no reboot and nothing is displayed.

I would try pressing and holding the power and volume down buttons until you get the short vibration. Hopefully after vibration you will be in bootloader. Then connect to a PC and try and flash-all the factory image.

Thanks for your response. Unfortunately, after the vibrations, I do not get anything on the screen. In my previous phones, I was used to flash ROMs and so on. I never bricked a phone. But with the Google Pixel XL, I must admit that I do not have anymore ideas how to rescue it. I have tried the following:
- holding only the power button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume down button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume up button for several seconds --> short vibrations after several seconds, but nothing else
- holding the power button and the volume down + up buttons for several seconds --> short vibrations after several seconds, but nothing else
I have made these tries with the charger plugged in, plugged out, and removed at different instants. Nothing more than just the short vibrations.

Your screen may be black, but there is a small chance your still in the bootloader. I have read that other people have recovered from a black screen. I still think its worth a try to connect to a PC and see if the factory image flashes after holding power and volume down and after vibration. Those vibrations have meaning.
Thank you, I gave it a try: the PC does not even ask to install a driver, when the phone is connected. I made several tests, exactly as it is required to flash it, but there is no communication with the PC. :crying:

I thought there might be a small chance. At least you will get a new phone. Best of luck.
I hate to tell you this but I had the same issue with a 32 GB 5 inch pixel...It was dead...Everything you have said is what happened with mine.
What happened was the slot the phone was trying to boot into had no bootloader or it was a bad flash...Either way, the slot didn't have a bootloader on it when it tried to boot and that black screen is the result...Google sent me a new one and all was well and they will do the same for you.
This is why I don't trust OTA updates...I manually flash everything and I'm sure to flash the bootloader to both slots anytime I update my phone...Good way to keep this from happening again....Best of luck man
You keep saying several seconds. You gotta hold the power and volume down for a pretty long while. Just saying.
Probably a bad boot partition though..
Thank you very much for your kind support, guys.
Your explanations is very interesting. This means that the strategy implemented for the bootloader itself is not very safe. I would be interested in knowing how such a faulty flash can happen and what are the possible reasons behind. Is there a procedure that can increase the chances for a successful flash by doing some things before the OTA update is allowed to be installed?

Believe me, I pressed the button for a very long while also (hours) by blocking the button in such a was that the phone boots up until the battery is discharged. So also such an extreme tray was made. The only consequence was the red light flashing.
Iam having similar(exactly) situation as stated by OP. Phone dead, only short vibration, no boot loader, no dshub qualcomm either detected while plugging USB to pc. Charging still ok.
update: now phone can be detected as Qualcomm HS-USB QDLoader 9008 in Device Manager.

Phone is in Qualcomm Emergency Download mode. What happened? Also a bad OTA flash?
You only have two options:
Press power button for ~ 30 seconds to get out of EDL. If it's completly bricked then RMA. You're under warranty yeah?!

HTC 10 Unresponsive & Can't Restart But Alive

I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.

One Plus-3 Black Screen. No LED No Vibration. Hardbricked?

So I had kept my oneplus3 on charge at around 10:00 Pm yesterday and fell asleep. Woke up around 12:00pm to see it was fully charged so I unplugged the charger kept the phone beside me and went to sleep. Today when I woke up I saw that the phone has a black screen and is completely dead. The LED light is not on. Plugged into the charger no response. Tried holding power button ..nothing. No vibrations or home button lights
Currently, there is nothing going on with the phone. No flashes on screen no LED. Absolutely nothing. Tried connecting to laptop (windows 10) dont see anything. It was working perfectly fine last night and i had used it for nothing but music then.
Question is.. is the phone hard bricked or completley bricked? what might be the reason? I searched youtube only to find 1 person with similar problem who had said that he kept the phone for 48 hours and when it was completely discharged he pluged in charger again and it started working.
I am confused. Have a lot of work documents inside and what if it stays the same after 48 hours?
Appreciate any help on the matter
update: Tried plugging in the charger a few min ago. The led turns red and Vibrates. Nothing else
Update 2: so after 24 hours of setting the phone aside. i plugged the charger and it went into charging. But now am facing a new problem. My bootloader is unlocked and the power button is busted hence whenever I press volume down and plug-in the charger it takes me to bootloader warning screen from where either it goes into charge or i press volume key and it goes into option which I again cant select cause power button is busted. Tried holding down the power button and connect to laptop(windows 10) no device detected and it works like normal charging. Tried to charge for a few minutes unpluged charger and start again .. it was stuck on oneplus screen. Any ideas??
