Bricked and bootloop after running fastboot oem lock - HTC 10 Questions & Answers

HTC 10 was running Viper10 ROM, booted into download mode and ran fastboot oem lock so I can RUU and send my phone back for a return.
Phone now bootloops immediately after turning on, HTC logo comes on for a split second and it just turns off again. I can't access or do anything. I can't boot into recovery, the phone won't let me do anything.
Am I ****ed?

I had a very very similar issue. Was getting bootloops right after the bootloader which is a good sign, fyi. It's only a soft brick.
I fixed the issue by restoring my stock firmware via TWRP. that's always your safe place and seeing you're a senior member I hope you made TWRP backup before you got funky with flashing.

How do I boot into TWRP?
As soon as the phone turns on, it just instantly turns off again or it loops when it's plugged in until I unplug it.
No button combinations work and the PC won't detect it.

should just be phone unplugged and powered off. the squeeze vol down and power until HTC logo appears. also did you use the sunshine for s off then go back to s on?

Phone was just S-on with unlocked bootloader.
I held down both volume buttons and the power button and it took me to bootloader mode, went to download mode from there and the RUU flashed and now phone is relocked and back to stock.
Thanks for your help.

Need some help daorderdillon...I have an HTC One M8
I wanted to flash to the UNROOTED Google Play Edition...so I rooted, TWRP'ed and did the S-OFF
and then tried to flash the ROM while in RUU mode...it gave me back a "41 error"...
so I tried to change the ModelID in the android.txt file...flashed, and then my HTC One M8 kept going into the HTC logo screen with 4 triangle error screen
When I do fastboot oem reboot, it gets me back into the device - but any normal restart after, and I'm back in the HTC logo error screen
I can't go into recovery mode either - using the POWER and UP / DOWN buttons or through the software...
Stuck, and I really don't know what to do
Thanks in advance!

Have you tried flashing a stock recovery via fastboot? Or flash TWRP again then flash a stock nandroid backup from the backup/recovery thread?
m8 white screen
Good evening community
I think I bricked my M8. Tryed to flash a custom ROM, unrooted and installed it but didn't liked and decided to go back to stock ROM. Went to TWRP and wiped one position more than needed - data. So now my M8 booted just into white screen with HTC logo, power off doesn't work at all, hard reset combination doesn't work, power on + volume up - doesn't work. It's always on and CMD says <waiting for device>
Who can help me?
Thank you in advance
Edit: got into bootloader, thanks to Niorun post edit.

For this phone, as long as the screen comes on, its almost certainly not bricked.
Being stuck with OS not booting is a common thing when flashing ROMs. It just happens from time to time for one reason or other. Folks that freak out about this (and think their phone is bricked) need to relax and learn some basic recovery steps.

Wiping data will not make the phone get stuck on the HTC logo screen. Wiping data just erases user data. So the phone would have just booted into the OS, but with no previous user data present any longer. Failure to boot was for some other reason.

Power + Vol Up reboots the phone, this should always function as long as the screen comes on.
Power + Vol Down to boot into bootloader similarly should always work as long as the screen comes on. Failure to do so is almost always a matter of user error, not performing the button combo correctly (either not pressing vol down fast enough, or letting go of it too early).
Power + Volume Down

Pressing Power + Vol Up does show the HTC screen for me, then it goes black.
Pressing Power + Vol down doesn't do anything.
Am I following the instructions correctly?

Try it this way:
1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears, let go of the buttons, and hold the Vol down button. Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.
Clarification
I have to anticipate when the screen is going go from black to showing the white HTC logo? Then do vol down then?
htc m8 brick
i too am having issues with a bricked htc 0ne m8. We purchased the phone as-is really cheap. its freezes while booting up. i can get into fastboot and recovery just fine. i have been successful in installing ruu files but the ruu file doesn't fix the "boot loop" freeze at startup issue. The device is s-on still which sucks because i can't find a method of achieving s-off in fastboot mode. i was able to unlock the bootloader, hoping that it would help and now the ruu files won't work anyone. now i can't get the bootloader to lock through the method that htcdev.com tells me to use. ive also tried to install update through adb sideload through recovery without success.
so i have a s-on, unlocked bootloader htc m8 that i still can't get it to boot up.
any help would be appreciated.

I just timed it (in my head, not with a stopwatch), and you have about 3 seconds while the screen is black, before the HTC logo screen appears. Plenty of time to let go of the power and vol up buttons, and hold the vol down button.
The reason I say "the moment the screen goes dark" is that some folk wait too long, and start pressing vol down when the HTC logo screen is already up. By then, its too late.

What hboot number?
What radio numer?
What CID (or original carrier version)?
What RUUs did you try?
Don't know what method HTCDev says to relock the bootloader, but as long as you can still get into fastboot mode, its simply the command: fastboot oem lock
Also, there is no other currently working s-off method aside from sunshine (which requires booting into OS) so you can stop looking for one.
I "Softbricked" my htc one m8 AT&T
i recently rooted it and made 4 back ups. I deleted two of them and tried to roboot to fastboot. but it says 'No OS installed" . My computers reconize it as a disk drive and when i click on it, it asks me to insert a disk...Please, ANYONE with information that will help, share

Download a ROM on your PC, transfer it to your extSD, put that in your phone and flash it in recovery.

Well, you say you can't get in the bootloader or recovery, have you tried to hold down the power button and volume up button, and then when the screen goes off switch to power and volume down? That should take you to your bootloader! If you can get there I would guess you would have a backup in recovery

It doesn't. The tool is very outdated, and I typically (virtually always) recommend against using it for that reason. The toolkit uses the old firewater s-off method, which hasn't worked since December 2014.
When I said there is no other working s-off method besides sunshine (and to stop looking for one), it was a statement of fact, not a guess.
I need some help, I have a m8 rooted and to make an update from htc (I have te stock rom) I have flash de stock recovery (te old one was the twrp) but now after the update de phone is stuck in the htc logo, I can enter in the fastboot but I dont know what to do and what direction I should take
Follow my steps if your phone is not booting up.
1. Lock bootloader if you have unlocked bootloader.
2. Download HTC One M8 4.16.401.10 Stock Lollipop RUU [0P6BIMG] ( search google because I can not post link since I am new forum member).
3. Rename the downloaded RUU to 0P6BIMG and send the zip file to your phone SD Card.
3.Reboot your phone in to the bootloader mode by powering off the phone and rebooting with Power button and volume down or use fastboot mode command : adb reboot-bootloader.
-This way our phone will automatically detect the RUU file that you pasted in SD card (step 3) and flash it.
Your HTC One M8 is alive

The advice given here is good, except it assumes too many things. There is the assumption of S-On, and of current firmware version. Also, if you are using ADB to reboot to bootloader, the user might as well fastboot flash the RUU.zip, or run the RUU.exe that is also available.
@W_KuP, Post the results of fastboot getvar all (edit out your IMEI and serial# ~ that's private info)
If you are indeed on WWE/International firmware, that RUU.zip will work for you. Download link here.
If you are S-On, you will need to relock your bootloader first. In fastboot: fastboot oem lock. If you are S-Off there is no need to relock your bootloader.

[Q] Phone Bricked - Might not be hard bricked

Hey all, today I unlocked my bootloader and s-off'd. I decided to install 5.0 GPE and convert to GPE. Afterwards, I was stuck in bootloader. I flashed TWRP to recovery and tried multiple roms to no avail. Then, TWRP started flickering and crashing. In a moment of stress and anger, I thought, hey, maybe it will work in the boot partition. I was wrong, and now I'm in a boot loop. I can't get to bootloader no matter what, and it just keeps showing the google screen, then the TWRP screen flickering, then reboot. Any ideas?

If it's in a bootloop press and hold vol down button which will take you into bootloader.
OR
hold power+vol up upto 10 seconds , as soon phone restarts press and hold vol down which will take you into bootloader.

Phone stuck in reboot loop

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.

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.

Stock Boot-Loop, out of options!

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

Doing what you said flashes the grey HTC logo, but then goes back to looping.

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

Whenever I plug it in while off, it shows the low battery icon and tries to turn itself on.

Yes you can RUU with the bootloader locked. Actually it's the only way you can 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.

No, I had to send it back to HTC and within 2 weeks they sent it back to me completely wiped and reset to factory.

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.

Ram Dump

I was on N2G47E stock, flashed N2G47O and my Pixel xl wouldn't get past the dancing dots screen. Tried entering bootloader mode and got a Ram Dump screen. My phone is now on its way back to google. Can anyone explain what might have happened so I can avoid it in the future?

I kept holding vol down + pwr through that screen until it goes black then let go and hold them again and it goes to bootloader

^^Exactly this. I found myself in a bootloop Sunday night and holding vol down + power during the Ramdump screen got me into the bootloader. From there I went into recovery and set things straight.
May I ask, how did you flash N2G47O? I'm gonna go out on a limb and say that the OTA or the image you flashed also provided you with the May bootloader which causes bootloops if you have TWRP as your recovery. A solution was found in another thread to flash the April bootloader instead.

I was stock, not rooted.. I flashed it in adb. I could exit the ram dump and could eventually get into bootloader but adb could not see the device. I tried factory reset and the issue didn't go away.

Once you are in bootloader adb does not work. You use Fastboot while in bootloader. You absolutely could have flashed back to stock at that point. Could have saved your data, settings and apps too. Just edit the flash-all bat file, remove the -w from near the end, save it and run it.

Sorry. I always use adb as a generic term. My devices wouldnt show up. How could I flash if it is not recognized. It almost seemed like the flash completed successfully and in doing so adb debugging was turned off as it usually is.

anybody else having trouble flashing any stock image on ubuntu? i keep getting the ramdump screen and can get into the bootloader fine but i seemed to have screwed up my boot slots a and b and cant flash a stock image for the life of me. any help would be greatly appreciated
Finally had time to figure out my issue...all you do is update fastboot to the latest which is I believe the 12th of May. Fixed everything and now can flash the boot images to slot a and b...

I got the same problem and couldn't boot into bootloader. Finally, your instruction saved my Pixel XL. Thanks very much!
