So I'm stuck on the HTC logo (with the This build is for development message..) and it looks like I can't do anything about it. I can't get into fastboot with the whole Press volume down + Power button. Buttons are unresponsive.
adb doesn't recognize any device when I attempt to reboot the phone into bootloader with the command 'adb reboot bootloader'
Any solutions?
What I did before this happened: Ran CM 12.1 for a good month then decided to go back to stock rom. I unrooted, flashed stock recovery, and locked the bootloader (did not flash stock rom yet). I decided to try another custom rom so I went to unlock the bootloader again. All seems dandy when it starts to reboot when I unlocked the bootloader, but now it's just stuck on that screen.
Edit: I just got around to reading some guide that tells me I should just wait until the battery dies since it's likely frozen. What a bummer.

Hold the volume up button and power simultaneously (for 15 seconds) to restart the device while on the HTC logo. If you can get into fastboot mode (Volume down and power button while phone is powered down), make sure you're running the stock recovery and have locked bootloader to run the RUU.

Hello,
I have here a Desire HD which was running Ice Cold Sandwich. The ROM became unstable, so I wanted to give CM 10.1 a try. This Desire HD was been HTC Dev unlocked, but is still S-ON. So, I can't flash the boot partition from recovery. I rebooted the phone into fastboot and flashed the boot partition. (fastboot flash boot boot.img) I thought it was possible to reboot to recovery with fastboot, but it seems to be not possible. So I did "fastboot reboot". And that's where the misery started...
Although I was able to navigate through the bootloader with the volume rocker, I seem to be unable to boot the device in fastboot nor the recovery. It keeps booting ICS. However, the volume down seems only to work occasionally. Because it's not running the ICS boot.img, it's stuck in a bootloop. When the device is "booting" and I try to reboot the device using adb, I get the message that my computer is not authorised.
I do the following when attempting to boot in fastboot or recovery: (I don't really care if I get the device to boot in fastboot or recovery. I can get the device to work in fastboot or recovery.)
I make sure that the device is turned off completely by removing the battery. Then I hold the volume up (that seems to be the best working one) and after about half a second I press the power button. I hold both until the white HTC screen goes away. I also tried to let the powerbutton go at the moment that the HTC screen appears.
Quick summary:
State of the device:
HTC Dev unlocked.
Running Ice Cold Sandwich.
Recovery is 4EXT.
CM 10.1 boot.img.
Bootlooping.
Not responding when holding the volume button when booting.
Unable to connect to it using adb.
Can someone please, please help me? I'm usually not a noob, but I really f*****d it up this time.
The worst part is: it's not even mine...
I fixed it. The volume rocker seemed to be the problem. I removed the sticker under the battery cover and popped the buttons out. While holding the battery with my left thumb, using my left hand for pushing the volume down button and pushing the powerbutton with my left index finger I got it to boot to the bootloader. Yes, it was pretty awkward. I flashed the ROM from the SD card and it boots.
My problem is solved!

Well that's one of the perks of flashing a 3.xx.xxx.x ROM on 1.xx.xxx.x(4.4.2) firmware. You get to have extremely long boot up times and you won't have a proper working radio which leaves you with no wifi, data, gps, bluetooth...
Your OTA probably didn't work because of a custom recovery, not because it was rooted. Root does NOT prevent OTA updates from installing, though you might lose root access after the OTA.
If you're stuck at Boot screen hold Volume UP + Power button for 10seconds, as soon as the screen goes black press volume Down + Power button to enter into Bootloader.
Flash a custom recovery like TWRP. Go into recovery and restore a nandroid backup for your device.
first thx alot for replaying
i already got TWRP installed but the screen is stock on boot screen but still manage on the back ground to load my current rom as i'm hearing the log in sound of the rom :S
so i tried to power it off without seeing by holding the power key the power option pop up and touching random parts of the screen but i failed
i even waited for the battery to empty and factory reset the phone with no use
is these is any way even by adb to power off my phone
plzzz help
thx again for replaying

By the look of things you are booted in OS but have no screen, hence why try and hold power button in and randomly tap to shut off?
I told you already to Hold Volume UP + Power button for about 10seconds and then hold volume down + power to enter bootloader.
You can of course also just plug it in and try to reboot to bootloader using adb, if you have USB debugging enabled. adb reboot bootloader
As already said just hold power and volume up for around 12 seconds then immediately press and hold power and volume down. This will always get you into the boot loader.
However if adb is working just use the command above. Reflash the original boot.img and you should be good.

Use that to get back to the stock rom for your phone. Then after installing the right one, get the OTA

Never leave your device with an empty battery. In any circumstances.
Because you might not be able to charge it. Recover the device while you have some power on your battery.
Remember, this is a unibody device. It's not so easy to pull out the battery.
Ok,
Was installing the viper rom on my M8, and for some reason, now my phone is stuck in a boot loop. Obviously the install went pear shaped. But now I cant even boot the phone into recovery mode.
Boot sequence now is: Google lettering appears on screen, followed by green android with the blue spinning shape in its chest, then the green android with the red triangle and black exclamation mark appears and the whole thing loops again.
When plugged into the PC its not recognized so I cant use adb to boot into recovery or try load another rom/wipe cache etc.
I've tried all combinations of power button & volume up/down to break the boot sequence, no joy.
Any ideas how to resolve, or do I have a very expensive paper-weight?
Cheers,

Rest assured, if the screen comes on, the phone isn't bricked.
Red triangle with exclamation point is stock recovery.
What was your exact sequence, in detail? From bootloader unlock, install custom recovery, etc.
Was the phone on Lollipop when you unlocked the bootloader?
To reboot into bootloader (not recovery, there is no button sequence to boot directly into recovery on this device):
1) Hold power and vol up for several seconds to force a reboot
2) The moment the screen goes black to reboot, let go of the buttons, and only hold vol down
3) Don't let go of vol down until you are on the bootloader screen
4) Failure to get into bootloader is virtually always user error. You either started pressing vol down too late, or let go of it too early. Just repeat until you get it right.
But from there, as mentioned it sounds like you are on stock recovery. You will probably need to flash TWRP again via fastboot in order to do much more.
Did you flash a custom recovery before you flashed the rom?? Can you boot in the bootloader mode (turn of Device completely- turn on again and hold volume down all the time.. then you should be in the bootloader)?
And your phone is not really bricked
Edit: damn to slow should not write on the phone

My friend, did you flash it using stock recovery or custom recovery? if you did flash it using stock recovery you will meet this kind of problems. I suggest you try power button and down if im not mistaken and go to hboot and fastboot usb and connect to adb, type fastboot devices in cmd if it detects your device then you can flash TWRP , find any kind of custom rom for M8 and flash it. I also assume your bootloader is unlocked and driver is installed in your PC.
Problem solved. Redpoint73's key press combination worked!

Hey guys,
Ok, this is a tough one for you. I'm actually not 100% convinced that my phone isn't hard bricked. But every where I look for, it says, it's only hard bricked if your phone wont turn on at all and that's just not true in my case. So here's the story:
My volume-up button is kind of screwed, I don't know, what happened to it, but one day, it just started being triggered randomly until it just didn't work at all anymore. It wasn't that big of a problem, since I was still able to change the volume by hitting the volume-down button once and changing the volume by the on screen slider. I was running SkyDragon GPE V5.5 for quite a while now.
But now I wanted to upgrade to Android 6.0, so I downloaded the firmware from here. Next I rebooted to bootloader switched to fastboot and used "sudo fastboot oem rebootRUU" and "sudo fastboot flash zip firmware.zip" twice. So far so good, everything went fine and I actually even am able to see the new Google splashscreen.
So now I want to flash this ROM. But, for some reason, the touchscreen doesn't work anymore, even though it's activated in the CWM Philz Touch GUI settings enabled. Alright, so I "wipe to install a new ROM" and navigate to the zip file to install it and it starts the aroma installer, which I can't control since the touchscreen doesn't work. So, I'm kind of frustrated by now, I flash TWRP, because, maybe here, the touchscreen works. I flash it and try to reboot into it. But it doesn't work, it just stays at the Google splashscreen, I can restart by holding down the power button but it will just go back to the Google splashscreen. After a couple of tries I actually get it to turn off, so I hold down power and volume down to get into the bootloader but it just goes back to the splashscreen.
I can't get to the bootloader, I don't have a ROM installed and I can't get into the recovery. Is there anything I can still do or is everything lost?
Which TWRP version ? You need to use 2.8.7.0
You can't get to bootloader because of the timing when pressing power & volume down button.
If you can turn it off, press and hold volume down button then press power button until it vibrates then release the power button.
Hello All,
my phone was bootloader unlocked, rooted, installed with custom ROM and custom recovery.
Selling it to my friend, I did a phone reset in the phone setting menu.
Seems like I have done the wrong way? should have done in the custom recovery menu (TWRP)?
Now seems like I can not boot up to recovery mode anymore, by pressing power & volume down button, it always boot up straight to normal state.
Questions:
Have I lost the custom recovery?
How do I re-install? go thru ADB mode?
Thanks!
That button combo reboots to bootloader, not recovery (which doesn't have a button combo to boot directly to). Its a subtle difference (recovery vs. bootloader), but important. Its nearly impossible for the phone to not be able to boot into bootloader (if the bootloader was damaged, you wouldn't even have the screen coming on). If that is what you are experiencing (can't get into bootloader), you are probably just doing the button combo incorrectly: Hold vol up and power buttons until the phone reboots. When the screen goes black, but before the white HTC logo screen appears, let go of those buttons, and only hold vol down. Don't let go of vol down until you see the bootloader screen. If the phone boots normally, you likely just got the timing wrong, either started pressing vol down too late, or let go of it too early. Just repeat until you get into bootloader.
Alternately, within OS (and debugging enabled) you can do:
adb reboot-bootloader
or
adb reboot recovery
Now, if you get into bootloader, select recovery, and TWRP still doesn't boot. Then yes I'd recommend fastboot erase cache, and re-install TWRP by fastboot.
Pardon me,
I used the wrong term, I mean boot to bootloader.
I also pressed the wrong buttons, vol down and power instead of vol UP and power.
Many thanks for your advise.
