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.

Your device is not 100% dead, mine was(no led's while charging...). While is pluggen in PC, try and hold few minutes(i held 8 minutes, YES 8 MINUTES) all buttons, volume + and - and power button, and it turned itself on lol.

Hello,
I'm a new user and this is my first post here. I felt the need to "contribute" with my somewhat of a unique case.
I bought the Xperia SL 48h ago, and managed to "brick" it. The phone just died on me during regular use, I was in astro manager at the moment of the brick, the screen gradually turned off, and the phone became unresponsive soon afterwards. It didn't react when I plugged in the charger or when I connected it to my pc, the LED was dead, power + vol up button combo was also useless, and the pc saw my device as "QHSUSB_DLOAD".
I managed to solve this issue by holding power + vol up button combination for four (4!) minutes. I didn't really have a stopwatch, but I was in the bus on road to the store to return the phone, and just thought I might give persistence and stubbornness a chance. Three bus stops later, the phone vibrates and just turns on normally, like nothing happened.
I don't know how bugs like this occur, nor do I know how to prevent them; I am going to pretend this was just a work of gremlins.
Bottom line - if power on + vol up button combo didn't work for you for a 5 second, 10 second or a 30 second time-span, hold them buttons for a couple of minutes and pray that it works. I hope this helps someone.
Best regards
Did it have enough charge?

Seems your phone got stuck and turned the screen off.
Holding power+volume Up forces it to shutdown without messing with the battery-removal.
So you might have been able to restart it successfully.

The battery was at 14% at the time of power+vol up wake up. I didn't charge it though, I plugged in the charger just to see if there was a LED on, but there wasn't any LED response whatsoever.

That must be it. At the moment of the brick, screen gradually turned off, with darker colors becoming instantly black, and brigther colors getting a yellow tint just before everything vanished from the screen. Thing is though, the phone didn't react to the power+vol up combo right away, but two hours later and almost four minutes of holding the buttons.
One more thing that I noticed was, when the phone was connected to my pc, if I held the power+vol up, the pc would add/remove my hardware in a cycle, or at least play the sound of a device connected/disconnected. The phone still remained dead, but returned later for a miraculous wake up.

I'm not an expert, but this is probably your phone entering fastboot mode and then being disconnected due to incorrect drivers on the PC.
Glad your phone came back though. Comatose phones are terrifying, no?

I'm not out of the woods yet.
Got myself a second brick, and I've been trying to work it out for the past 24+ hours. I won't post about it on this thread, I've posted here: http://forum.xda-developers.com/showpost.php?p=39847797&postcount=532 , but I will report back with any advancements on the matter.
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?????
Have you got delvolper options enabled, if so when connected to your computer you could try Adb reboot or Adb reboot bootloader

Well only thing I can suggest is you leave it on charge over night. Then try & power it on if no go try and hold the volume up and power button while plugged in for at least a minute if that Dosent work take it back where you got it from.

Unplug phone. Hold vol up and power for 10 seconds, let go, try to power on phone.
So I got an HTC One second hand. Listing just said user reset it and started bootlooping. Got it for cheap so I figured I'd try and fix it.
Got it, and plugged it in (dead battery). The charge light indicator turns on, and the screen turns on with the charging animation, but only for a split second. Then it goes to the splash screen for about 10 seconds or so, screen turns off for a few seconds, then right back on and up to the splash screen.
Tried holding the Vol down to get into bootloader, but so far no good. The only way for it to stop the loop is for the battery to die. When I plug it into an outlet or a computer, it immediately goes right back into the boot loop.
So, is there anyway to save this? Or am I SOL?

Thanks for the reply. I recognize you from the Rez forums when I used to have one .
So, tried that. I plug it in (device is off now because it ran out of juice apparently), and the light blinks, splashscreen comes up for 10 seconds.
After that, it reboots, and the charge light doesn't come on again, and then goes into its bootloop.
I also tried holding the Vol down for around 3 reboot cycles, both on and off the charger.

Is it a goner?
to me it sounds like there is still hope. as long as you can see the splash screen you still have a chance.
i would put it in a wall charger and just leave it for a bit about 20 min and then try the vol - and power.

That's what I was thinking as well, going from my experience with the Rez anyway.
Alright, I'll just let it sit on the charger for while and hopefully the buzzing doesn't annoy me too much lol.
Still can't get into bootloader .
Tried after about 30 min of being on the charger.
Something weird I noticed, if I press/hold power+vol down while it's on the splash screen, the back/home soft keys will blink 6 times, then the phone shuts off/starts back up again in it's loop (but they won't blink if I was already holding them down before the splash screen came up). Not sure if this is relevant or not, but I figured I would mention it.

Tried it - screen still just goes black, and then repeats the splashscreen bootloop like before.
Should I try contacting HTC and see what they would charge to send it in?

I have this happen to both my max and my kids m8. It was a matter of timing the power and up button combo and then shifting to just vol down the second it rebooted. First time took me twenty minutes to get it right. During which I may have broke a sweat. Don't give up just yet.

So, I should hold Power + Vol UP while on the splash screen, then when the buttons flash, switch to just Vol DOWN? Or am I not doing the correct technique?
So this is what I've tried doing; not sure if it's the correct timing or not:
From a dead battery, plug in and hold power + Vol down, it just goes into bootloop
During the bootloop, held Vol Down during the black screen in between the white HTC splashscreen; still bootloop (tried this at various times in between the splashscreen loops; there's about a 5 sec gap of black screen)
Tried the same above, but with Power + Vol Down
Tried Power + Vol Down during the white splashscreen, the back/home soft keys blink 4 - 6 times, and releasing the power button while keeping vol down held, and then reboots into the bootloop again
Not sure what to do at this point, besides contact HTC, unless you guys have any ideas/proper order to press the buttons?
Edit: plugged it into my computer, and about 3/4 of the way through the HTC Splashscreen, I hear the USB plugged in noise, then immediately the eject noise. For a second I can see "Android Phone" listed under Devices and Printers. Tried running fastboot reboot-bootloader and it didn't catch it. Tried running adb devices during the second it's recognized, but it didn't see anything. Tried in both USB 2.0 and 3.0 ports.
Also tried pressing Vol down during the time its recognized, but either my timing was off, or it didn't work.
Update: Also tried holding the light sensors under a lightbulb and tried the above attempts (read somewhere this has worked for people)... still a no-go.

Still haven't been able to get it after a couple days of trying on and off.
Contacted HTC and I'm going to send it into them.
Since I'm not sure what HBoot is on it currently... if they were to update it to the latest (newest OTA) that's just been released before returning it to me... will I still be able to unlock bootloader/S-Off with Firewater/Weaksauce?
Thanks for the suggestions you guys provided dottat and synisterwolf I appreciate it!
sorry ive been away, work has be busy. If they do update it, there is no way to unlock or s-off ATM. the OTA might be to new for them to care and just flash you back to 4.4.2 sense 5.5

No problem man.
Lame.. hopefully hey don't update it. According to the agreement notice they emailed me with my ticket info and stuff, it says" Please note that all repaired devices will be set to carrier or HTC specifications, and will be factory reset."
Hopefully that means that they'll just reset it back to how it came and not update it.
Otherwise I guess I'll either wait or try and sell it, since the device itself is pretty much mint.
So I got it back today from HTC... and I think they updated it . Can somebody confirm for me?
Bootloader says this:
PVT SHIP S-ON
HBoot-1.57.0000
Radio-1.13.41.0421
OpenDSP-v32.120.274.0909
OS-4.10.605.3
Settings says:
4.4.2
Sense 6.0
4.10.605.3
So there's no way to root, or S-Off, or bootloader unlock right? Neither Rumrunner nor Firewater work? Is an unlock exploit being researched?
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

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?!

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...
