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.

Fantastic! Recovery backup is restoring as I type. Now to Sunshine, S-OFF, updated HBOOT and THEN CM12.1.
Thanks!

Hey guys
I'm running MrGarak's fantastic MIUI rom however I've found that the kernel is booting my phone into that white HTC diagnostic screen by default. Unfortunately my volume down button is dead and so I can't navigate the menu; the only way I can boot my phone at the moment is to boot it connected via USB as that makes it boot to Recovery and I can reboot from there.
Any ideas? I think this and another rom I tried both used LordMUE's kernel, could that be the reason the boot preferences don't default to just booting the OS?
Any help and/or pointers would be greatly appreciated
So you can access bootloader and recovery!
So just flash another kernel. What's your problem?
Put a zip on your SD (with a SD reader or ADB pull), then go in recovery, navigate with the 4 keys under the screen (or vol+ and power)... and flash.
What is strange for me is that it seems to happen sudenly... so how do ou know it's the kernel. Anyway...
I have clockwork recovery, and can navigate it using the soft keys (home menu etc). You should also he able to use the vol up key to get to the bottom of the list, (depending on the recovery you're using I suppose)

Unfortunately it boots into the white HTC area (dunno what it's called). The one where you can see if your phone is S-OFF or not.
Also, I'm not sure what is to blame... but I've only just recently noticed that my phone cold boots this way so I assumed it was a recent rom that I applied. Will test this theory later.
Sounds to me like your volume down button is stuck in.
Definitely not a ROM issue, as it has nothing to do with the bootloader.

Hey, i had this issue like a month ago. You can check my previous threads. It's hardware I'm 100% sure. Basically if you're in warranty you need to flash the stock rom with S-On so you can get a new phone. You can get it to boot but it's really a pain. You have to play with the volume up when first turning on your phone. It took me about an hour. Then when it boots you'll be in a "Safe Mode" (no clue whats limited all seemed fine to me). Then do your backup if you wish.
Also note: Flashing the S-On rom is a PAIN, took me about 2-3 hours of rebooting, holding vol up, tapping vol up, to get it to boot right, but with patients you'll get it to go.
Good luck to ya.

Ah, I'm definitely beyond warranty. The thought of vol+down being stuck down makes a lot of sense!
I'll just take it to one of the dodgy Asian repair shops, if it's a hardware issue I'm sure they'll know what to do.
Cheers for your help everyone!
I have unlocked my bootloader then install the recovery.
And I am flashing a ROM ,but as I came from Atrix the step was to flash from recovery
I didn't read the instruction and flash the ROM through recovery without flashing boot.img first
Now, I can't boot to my ROM (It stuck at HTC quietly brilliant screen)
So, I reboot it and try to enter fastboot ,but not either. I can't get to fastboot. pressing volume down and power
Then, I was unable to turn it off. I disassemble and take the battery out. and charge it for an hour now. But, still no luck can't get to fastboot.
Anyone can help me.
I am so dumb if I have read the instruction, I wouldn't brick.
I don't know what pure doing wrong, but holding down power and volume down will get you to hboot. From there you can go to fastboot and then flash the boot.img.
Not even hboot too. press volume - and power doesn't do anything for me. or do they need more battery?
Then you're doing it wrong or your buttons are broken.
Keep hold of volume even after it reboots. Don't let go until you're in hboot.
When I first installed custom ROM I made the same mistake and didn't flash boot.img separately, causing the device to just hang at HTC screen you described, or being in a constant bootloop. However I was able to get into bootloader and sort things out. I know it's something basic, but are you making sure you hold that volume down + power button long enough?
Oh GOD! I got it! It boot into hboot and I can fastboot now. I think the button are hard to press so, I can't press it correctly the first time. THANKS
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.
Hello,
I installed a custom ROM (ViperOneM8+4.6.1) on my M8, which is the international edition M8QL_UL.
I now suspect this ROM is not compatible, as the phone is stuck in a reboot loop - the white screen with the red text at the bottom appears, and then about 35 seconds later the screen goes blank and it restarts.
I've tried holding the power button down to try and turn it off, but it won't stop restarting.
I've tried holding the volume down + power buttons to enter recovery and it doesn't work.
Adb and fastboot don't work either - the phone isn't on long enough to appear on my PC.
Please let me know if there's anything I can do at this point?
Cheers.

Your device is not a M8 but a different device called M8s ....

There is no button combo that boots into recovery for this device. I believe you mean the button combo to enter bootloader. Folks will often call this recovery, but bootloader and recovery are 2 completely different things (and this is an important distinction), and folks need to stop thinking they are the same.
Since the phone is bootlooping, just hold the vol down button during the next "loop" and you will enter bootloader.
Once in bootloader, then you can select to boot into custom recovery. Then restore your stock nandroid, if you made one before flashing the custom ROM (and you should always make a nandroid of the stock ROM before flashing a custom ROM).
If you didn't make a stock nandroid, you'll need to use RUU or find a stock nandroid that matches your firmware number.

Fastboot only works in bootloader-fastboot mode; adb only works in OS or recovery. So neither is ever going to work while in a bootloop. Get into bootloader as I've described above (and select fastboot); and you should at least be able to use fastboot.

Thanks for the suggestions and advice - I've got the Pandora Rom back on it now and won't be fiddling anymore I think.
I actually managed to get it sorted by holding vol-up and power for a good 15 seconds based on advice from the M8s thread, just in case any one has the same problem and vol-down doesn't solve it: http://forum.xda-developers.com/showpost.php?p=63177320&postcount=658

Power+vol up reboots the phone. You stated the phone was already in a bootloop, which means it was already rebooting over and over.
Vol down (just vol down, no need to hold power button) during any reboot will put you into bootloader. If it doesn't, its because you didn't hold vol down long enough.
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.
