Haven't seen this before. Did you try to do anything before this happened?

Try getting your bootloader unlocked and flashing a custom recovery. Or if you have a SD card, try placing a firmware inside to let the system install the firmware. I'm s-on so I know not much about s-off. Or you can always send it back to warranty stating that you have no idea what happen to your device

I had that happen to me when I relocked the boot loader your going to have to run the appropriate ruu on your pc with your phone plugged in and on the bootloader screen

Ok think i figured this out was in the same boat you need to :
1:Boot into your bootloader
2:click fastboot
3:goto computer download squabbis htc one toolkit 3.2.x
4:install drivers for htc if you havent already
5:click fastboot got to the flash section
6n your computer download newest custom recovery you want
7:locate file from flash section then select partition recovery should have your custom recovery back
8:install desired rom from sd card if no sd card can be viewed try mounting it if that doesnt work reboot into recovery and click fast boot go back to computer open cmd where from your abd folder is and type in "fastboot oem enableqxdm 0"
hope this helps please report back to let me know if it worked
CHEERS plz click thanks if this helps anyone else

i can't flash recovery because my bootloader is relocked ( if i try ., it'll say "FAILED (remote: signature verify fail)" )
i tried to unlock bootloader but htcdev give me an error ( Error Code: 150) :
<<We're sorry, but it appears your attempt to unlock the bootloader on this device has failed. This could be caused by several factors including simple errors in the entry of the unlock token, problems with your device, or a lack of manufacturer support for the unlocking process. Please see the specific error code listed below, and try again if necessary.
Error Code: 150.

Try the token again. You have to copy and paste everything including the <<<<< >>>>> but none of the "bootloader" stuff on the side.

Make sure you don't have any "spaces" selected in it too.
Should be a problem with the copy/paste of the code, the reason says it all.

I know this is an old topic but for those experiencing the same problem, you need to go through the token request process via HTCDev all over AGAIN. The old token that you used to unlock is not valid after you relock as it has a different value.
Once you get the new token you can copy it to the fastboot folder and then in command prompt use the command fastboot flash unlocktoken Unlock_code.bin to unlock.
Hope this will be useful to someone in a similar dilema.

A5DWG - Phone Won't Boot

Hi there,
I have a HTC Desire 816 dual sim, i've been using CM v13 for more than 1 years, everything smooth after i changed my custom rom to MoKee (Nougat version). I got several isu when using MK, such as camera not working randomly, phone turned off when the percentages still > 20%, etc.
After that, I install another custom rom Lineage v14. I still get the same issues. And 3 days ago, I got my phone can't boot at all.
This is my phone detail :

Okk lets start.......
1st go to fastboot and connect phone with PC and use minimal fastboot and adb to flash recovery on your device. Command "fastboot flash recovery twrp.img"(recovery.img must be renamed as twrp)
2nd type fastboot reboot-bootloader
3rd type exit.
Now phone will boot to bootloader, from bootloader go to recovery and wipe everything including data system cache dalvik cache internal memory external sd card(if inserted). Now flash lineage OS 14.1, wipe cache dalvik cache, flash open gapps pico 7.1(arm) and wipe cache dalvik cache again now reboot
---------- Post added at 09:58 AM ---------- Previous post was at 09:55 AM ----------
Now if u are unable to boot into recovery then last option is to extract the system.img from system.new.dat and flashing the system.img by booting into fastboot and running these commands
"fastboot flash system system.img".
Now try and see if it works or not

:cyclops: after the last step (3rd step), i go back to hboot then choose recovery, suddently my phone restarted and still can't enter recovery.

where do i find the system.new.dat ?? if u mean by extract it from Lineage ROM and rename the system.new.dat into system.img, i've done it.
and still, the phone won't boot into recovery or normal boot, phone still suddently turn off and on again.

No no renaming it wont work. First u have to download Auto tool unpack repack from here https://forum.xda-developers.com/general/general/tool-auto-tool-unpack-repack-rom-t3278393.
Now extract the lineage os zip, u will get system.new.dat, file_contexts and system transfer list. Now open file_contexts with notepad++ and save it, choose the type as "All" and save the file, it should not be saved as a text file.
Now open the unpack-repack tool and copy system.new.dat, file_contexts(new one) and system transfer list to the input-dat folder. Now open the unpack tool and click on unpack, there u will get one file named as system.dat.img/system.img(.img is the format). Okk now the actual work begins follow my directions carefully.......
1st make sure u have htc usb drivers, universal adb drivers are installed on your PC.
2nd Download minimal fastboot and adb package from google.
3rd copy the system.dat.img/system.img file to minimal fastboot folder.
4th Boot your phone into fastboot mode and connect with your PC
5th Inside the minimal fastboot folder press shift and right click(mouse button), there u will see "open command prompt here" click on it.
6th Now in the command prompt type fastboot flash system system.img/system.dat.img
7th after the img file gets flashed type fastboot reboot, hope so your device will reboot

@bigsupersquid plz provide him with the system.img if possible

The hboot variables look like the battery is flat dead.
ROMs won't boot with no battery power, they reboot themselves without starting up.
Recovery might do the same, but it didn't used to.
You try a different usb cable to charge with? Usually mine go bad the other way, they still charge badly but lose data and won't talk to the phone, but could be bad cable.
I'm not sure if you can charge the phone in fastboot, might try leaving it plugged in a couple hours. Then do the getvar command with fastboot again and post that battery voltage it gives you.

HTC M8 Can't get it to boot to the home screen

Hey, whenever I attempt to power on my m8 (bought it from ebay) it won't boot up and the only responce that I can get out of it is when I hold the power button the the volume button down it will go into the bootloader screen but whenever I try to go into the rrecovery section, the second that I press the power button to select that option it wil display the htc startup white screen, It will show that for about 10 seconds and will then turn off again, I'm not very phone literate so any help is much appreciated thanks!

Did you get that phone in this condition or was it working before? If it was working before what did you do?
Can you post your getvar all info? You need fastboot for that. Post this please and remove imei and serial no.

I did recieve the phone in this condition, originally the micro usb charging port was faulty so I fixed that by replacing it but besides that I have done nothing to the phone as I have not been able to.
Can't get that info yet as the phone will randomly not work for a couple of hours.

Can your give at least some info what hboot says like radio, is version etc?
How do you boot into recovery? You need to select that in hboot and wait till you see a phone with a red triangle. Then you need to hold the power button and click only once vol up to entering stock recovery

Sorry the phone isn't wanting to cooperate atm, won't do anything for some reason, will message back after work.

I haven't seen a RUU for this phone. The only option right now you could try is to flash firmware according these instructions posted here
https://forum.xda-developers.com/showpost.php?p=60218734&postcount=5
Your OS is 6.12.61.4 so the first file linked in this post is the correct one. Download and follow instructions at the end of the linked post. Maybe you're lucky.

Flashing firmware alone will not get the phone running. By definition, even on a working phone, flashing firmware makes the phone unable to boot, as it expects an RUU is be run.
Alternately, the OP can try to unlock the bootloader, install TWRP, and restore a stock TWRP backup from the first posts of the same thread you linked the firmware from: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

I have to disagree. There is no RUU for my cid as well and just flashing firmware didn't produce any booting issues. How should he flash twrp and restore a backup when his phone just shuts off as soon as it booted or rather it doesn't stay on?

I agree, he probably won't be able to.
And along those lines, if it shuts off while firmware is flashing (particularly hboot or radio) he will BRICK. Although, the phone may be close to death, anyway.

Seems like hardware issue imo.
Your M8 is blue - have you changed the unibody or it was just a blue model?
Also - was your drawer a dry place? Maybe some moisture somehow got into it.

Yes blue , I've store it in his original box in a dry place

I'd flash a ruu as a last line of defense if it's a software thing.
If that doesn't help then it's a hardware problem, probably the screen. If you're lucky then reconnecting the screen ribbon might fix it, if not - you need a screen replacement.

This error tells that you're trying to flash a ruu that is lower than your current firmware. Try this one - https://androidfilehost.com/?fid=24369303960687057
Also a short guide I've found, just in case

HTC M9 Stuck on bootloop

Hello,
I have a friend's HTC M) which is stuck in the black HTC logo loop, approx 1.5 second loop that goes on and on until it dies from battery depletion.
This happened after some heating up by the phone, so my search points to corrupt data on Nand memmory (or Nand itself died), don't know whter we can reverse it or not.
After some tries, I managed to get it in recovery mode, and wiped cache and data, both completed with errors. I attached some pic of it.
If from recovery menu, I choose reboot into bootloader, it reboots and gets stuck on white screen with HTC logo (not the black one I spoke before).
I have been reading the HTC M9 thread, but I don't know which nex step to take.
This is an unbranded M9, without any rom modifications.
Model OPJA1000,
Software status: Official
Locked
S-ON

I still haven't made progrss, since I got no help and even searching I got no easy solution. One thing I did make was a somewhat easy way to access recovery by trial and error. I disassembled back cover and tied to boot to recovery. If it entered in the bootloop, I'll just unplug the battery and tried again and again. With some tries I can get to recovery. I'll try to install from sd card to see if I can fix it.

While I put into recovery or download mode it shows this screen.
My one doesn't go into bootloop just stuck on this screen.
Do you think it can go to download or recovery mode with your method.
Thanks

If you can't get to download mode then the phone is broken.
