i seem to have hard bricked the device and i have been attempting to find a way i can fix it for hours.. i seem to be stuck. Its stuck on the boot animation cyanogenMod logo. I am unable to get into the recovery mode, as well as fast boot mode. i let it sit on that boot logo for hours without anything at all happening. No progress what so ever. Now the biggest thing i am trying to figure out is how i even managed to get this to happen. there was a software update notification that i received, so i figured it may have been the Android L update or something, so without taking into considering what exactly i was agreeing to i accepted, and continued. Let it reboot, and thats how i got to come across this issue. Any suggestions.
So if you hold down "volume up", "volume down", and then press and hold the power button, does it not boot into the bootloader? You may have to hold all three down for 15 seconds or so... Based on the fact that you can see the boot animation, it tells me that your bootloader is indeed functional, so, once booted into the bootloader, you can easily flash the factory images (as per this) and restore your device to working condition.

Yeah ive tried that, and nothing is working it just keeps going back to that same boot animation & im out of ideas. Iknow there has to be a way though.

What I find strange is that it boots to the boot animation -- that means the bootloader has loaded up the kernel and Android is attempting to start. The bootloader loads up before anything, so it is obviously working. Don't know why you can't access its menu though with the 3-key press. Maybe one of your volumes keys is not working properly? By holding those three keys down, it should not boot to the boot animation...
Can you get into download mode? Hold only volume down and press and hold power. If so, then you can use Odin and flash a stock ROM as per this thread.
In any case, if you can't get into the bootloader or download mode, then your only option is using OMAPFlash (as per this thread). That will re-flash your bootloader. If you still can't get into the bootloader menu after that, then there is a hardware issue.
Hi there,
So recently I just tried rooting my HTC One M8, with the All-In-One tool kit. It was successful, I was messing around with it for a while, removing bloat wear, ect. Then I figured out about custom roms, and heard about CyanMod11. It turns out that it couldn't read my sim card for whatever reason, but it still worked and loaded up. Then, I tried Android Revolution. THAT one worked flawlessly, besides the fact that I couldn't take screen shots for whatever reason. I should of just left it there. Here's where things go wrong. Then, I tried ViperOneM8. After that, it failed to load up and is now in a endless boot loop. I can't get into fast boot either. However, one time I somehow did manage to get into fast boot, but I didn't see the "recovery" option anymore. So... I'm out of ideas here. I'm really worried I bricked my device for good. My device powers on and everything, it just won't load up any OS, and I can't get into fastboot/recovery. Why I'm mainly worried is I failed to create a back up also. I'm running out of ideas here, and if ANYONE could help me that would be great.

first you posted in the wrong forum this goes in Q&A
second what do you mean it won't go into fastboot / recovery ? what happens when your in the bootloader ?
I need the results of fastboot getvar all to determine what files you need to fix your phone ( not you serial no. or IMEI)
most likely your on an older firmware and you have s-on and the Rom you flashed requires s-off and the latest firmware
Gah sorry, I find this forum layout kind of confusing. So this is another problem. I cannot access "getvar", it just says device offline, and I close that command prompt and then the next one just says "please wait," and nothing happens.
What I mean by it won't go into fast boot, is when I hit power + volume down it won't load anything. Here's a pic I found off Google, I can't get to this screen here.

Easy way to get into boot loader
Turn on your phone
When it gets into bootloop
Press and hold power+vol up+vol down until screen goes off
As soon as that happens press and hold power+vol down
You'll be in boot loader
And I must say you are a major noob
Navigate to hboot using vol buttons then press power button to select, you'll find recovery
These are just 2 modes hboot and fastboot
From fast boot you can select hboot and vice versa
And also getvar will work ONLY when you're in fastboot mode
Hboot mode is used for accessing recovery

I fixed my HTC One M8! Followed some advice on another thread and I just reflashed my TWRP, then I flashed the ROM again and everything is going smooth now!
Okay, stupid and impatient me wanted to update to CM12.1 without realizing some of the technical issues that I have now discovered....
Long story short, the last thing I did (and first really) , was flashing the boot.img from the CM12.1 zip using fastboot:
Code:
fastboot flash boot boot.img
What I now have is the white HTC boot screen with the red development build text block, and that's it. No recovery, no bootloader, no love.
Am I screwed?

No, you are not. Nor do I think you did anything stupid, as simply flashing boot.img (as long as you are sure its the right one for the M8) will almost certainly not cause any permanent damage to the phone.
This is simply a no-boot condition; not a brick. Hold power + vol up for 10 seconds or more, until the phone reboots. The moment the screen goes dark to reboot, let go of the buttons, and just hold vol down. Do not let go of vol down, until you see the bootloader screen. Failure to get into bootloader by this method is almost always a matter of just not doing the button combo correctly (the timing if a bit tricky) so just repeat until you get into bootloader.
From there, boot into recovery, restore your nandroid, flash a ROM, etc.

Hello,
My friends own an htc m8. A non professional lab has flashed him Android Revoultion Rom (without making a wipe, he used to use stock rom before that)
Since than the device suffer from a lot of problem,we would like to flash a stock rom.
What's the problem? the device refuses to go into bootloader at all & than refuses to turn on, only after a while in the charger it does turn on.
But any attempt to make the device go into the bootloader, has failed.
tried also RUU - it won't load the bootloader, and the pc recognize him as QHSUSB_BULK if the device is off, which is soft brick as far a i know.
The device actually turn on after a while, than when i connect it to the PC, the pc does recognize him normally.
What's the best option to flash a recovery and a stock rom?
Thank you.

There is definately some information missing here. Flashing a ROM without wiping will never get you into this state, unless maybe the ROM was meant for a different device.
It sounds more like a deleted bootloader partition, or borked eMMC.
It's bricked. You need to take it to a shop to see if they can JTAG it back to life.
Sorry.

Hey,
We don't know what they have done exactly
They device does turn on after a while... Can i just flash the whole bootloader through the computer anyhow? If the device is on, the computer does recognize him and i can use adb/transfer files.
In a few minutes when the device will turn on i'll write the software information

Have you tried turning off the phone, and booting it by holding down power + vol down? That should take you to bootloader. It's not bricked if you can boot it.
Tried that already...Doesn't work. The device refused to turn on that way.
Tried also through adb/an app when the device was on (yeah it's rooted), than the device turned off and the computer see it as QHSUSB_BULK.
Than i have to plug it off the pc, connect to AC and after a while it's just turn on by itself....

Not sure about this. If you didn't have a bootloader, I don't think your phone would boot at all.
It does boot, but not normally.
Anyway, there's no way of getting into bootloader
Did you enable developer options and within those option check USB debugging, so it's enabled. If not got to "settings > about > software information > more" and tab the build number entry several times until you get prompt the developer options have been enabled. Then got to developer options and check USB debugging. Try running the RUU again. Many this already works. Otherwise we'd have to look further.
Send by the swarm intelligence of my coffee machine ?.
I hgve already enabled dev options. once the ruu tries go get into the bootloader, the device just turn off and i can see on pc device manager it's QHSUSB_BULK

Meaning what, specifically? Stuck on HTC logo screen, or something else?
As long as the screen is on (on any screen), you can:
1) Hold Power + vol up for 20-30 second, which will force a reboot.
2) The moment the screen goes dark, let go of those buttons, and only hold vol down. Don't let go until the bootloader appears.

I'm still confused about what you are describing, and I think others trying to help are confused also.
You said the phone boots, but not normally. I asked what that meant specifically (which you did not answer at all). Stuck on HTC screen?
So the screen is on, when you try the button sequence I suggested? Then when the screen goes black to reboot, it just stays black?
Hard to help, if you don't provide details and specifics.
The phone boot and you can use it, that's how i have provided information from the settings. If i try to reboot, the device does not turn on. only after about 5 minutes.
same for bootloader. if you try to get into bootloader from adb for example, than there is only a black screen and after a few minutes it's just load the OS normally. but no bootloader.

So if you try the button combo I suggested, it eventually boots to OS? Are you still holding vol down when it boots to OS? If not, you should be (and let go too early).

What's the exact adb command? I'm sure you probably have it right, but just want to confirm.
It doesn't boot when i try the button combo... and after a few minutes it boot to OS.
also tried though an app because the device is rooted.... and also through RUU. The RUU restart the device and should make him to go into bootloader but it failes doing it.
adb reboot-bootloader
when the device is turned off the pc only see it as QHSUSB_BULK

It still really confusing how you are phrasing things "It doesn't boot . . . after a few minutes it boot"
Either it boots (just takes a long time; or boot OS, but not bootloader) or it doesn't.
Holding power + vol down makes it shutdown, right? Once the screen goes dark, hold only vol down and don't stop until you either see bootloader or the OS loads. Its not clear from the way you've typed it, but it sounds like you are pressing vol down for a while, then give up and let go, then it eventually loads OS.
I understand that it doesn't look like it wants to boot into bootloader, from any method. But we really need to eliminate all possibilities and be sure you can't do it with the button combo.
Its really unusual to see a device that can boot into OS, but not go into bootloader at all. I've never seen this once, after being on these forums extensively over the course of 4 different HTC Android devices.

Yes, Holding power + vol down makes it shutdown. After the screen goes dark, i tried to hold only vol down. nothing happends. tried to hold it for a few minutes. nothing.
When i release it, only after a few minutes, the device load the OS by itself (if i try to press the power button it doesn't work at all)

So how do you know whether releasing the button is a condition of it booting, or a coincidence?
For that matter, how do you know it won't go to bootloader if vol down is held when it finally powers on?
I'd say the answer to both those questions is: you don't know. At least, not for sure.
How long is a "few minutes"? 3 minutes? 10 minutes?
Maybe hold down the vol down button with some tape, if you can hold it down manually the whole time?
It's doesn't really Matter, as the adb/ruu/quick bot app should have be able to load the bootloader....

It does matter. As I already explained, you should eliminate all possibilities. At least I assume that someone who genuinely want to fix the phone would try every possibility.
You spent about as much time replying, as it would have taken to try my suggestion.
I agree, I don't think it will work. But you don't know if you don't try.
I was at work the night before, and my capacitive buttons stopped responding, so I went for a restart in hopes they would kick back on, this just caused my phone to enter a boot loop. Soft resetting and hard resetting both continue the loop, trying to enter recovery mode throws me back into the loop, entering download mode locks the phone on the small HTC screen. I tried to flash the current RUU onto the phone, but it won't proceed with the install due to a low main battery error despite the fact I've had it charging for 6 hours. The only thing I can think of doing now is sending it back in hopes they fix it, but theres a lot of information I ignorantly haven't backed up, and now can't access before sending it back.
If anyone has any helpful tips or ways to move forward I would be grateful.
you might be able to intervene in the process. when the phone restarts (ideally right after it restarts), hold Volume Down until the grey HTC logo appears, From here, you are in the download menu (or what is now basically the fastboot). If you are stock, you can unlock the bootloader if you havent already and flash a custom recovery (TWRP). Being in TWRP will give you USB access to your phone. And it will provide the ability to flash ROMs, including stock ROMs. Beyond that, you could always try a factory reset from either the download or the bootloader, but not much else I think you can do.
Someone might have more information than me though

Try the same thing, but this time with Volume Up, hold it until the FTM menu appears. From here, you should be able to access the bootloader.
If that also does not work holding Volume Up and Down at the same time takes you straight into the bootloader. Sadly, unless you are S-OFF, there is not a lot you can do from this menu. I dont think it accepts the fastboot commands, particularly fastboot flash commands. But if you can get into the bootloader, and then try each option, download, recovery, etc.
If you get into the recovery, it will be stock (unless you flashed a custom ROM). You have to press volume up twice to access the options, but if you get stuck, hold volume down and power and the touch keys on the bottom flash. After about 15 flashes the phone reboots.

Holding Volume up just continued the loop, I can get into the bootloader like you said, but theres not very many options, download locks the phone onto the HTC logo and doesn't proceed, the recovery option just restarts the phone into the loop.
Im afraid then, that I am out of suggestions for the time being.
Presumably your phone was charging whilst off, and not boot-looping?
Otherwise you can power down from the bootloader and try charging it. That may give you a better chance with the RUU

Mine does not charge either...and RUU does not work because of the battery < 30%
The funniest thing is that I've never touched this phone either (stock, no s-off, no unlock, no custom recovery, just updated via OTA to get Nougat), it just ran out of battery during the night and found the boot loop the morning after when I plugged it. Can't believe it could turn into a f...ing brick by itself.

My friends s7 completly bricked doing the N update. If you havnt done anything to your phone just take it back and get a new one.
Same exact issue here after the Verizon OTA update.
Failed after the first reboot after the update.
The storage was pretty maxed, wonder if that has something to do with it.
