Broken recovery?
Reflash your recovery in fastboot and try again

try some fastboot command once plug to Ur comp. like fastboot devices.
if right answer (serial number phone) could tell that it s just software failure and not hardware...
hope for you it s only software issue

Device Bricked

Hi,
I had unlocked my boot loader to flash TRWP. But after unsuccessful attempt of H2OS installation I tried relocking my boot loader. Now device is not starting and its just showing blank screen. White Notification LED is there but nothing on screen. Need urgent help.

You...locked it with H2OS and...what recovery? What did you even do

I had official TWRP installed. I booted device into Fastboot mode and run "oem bootloader lock" command

Why? there is no real disadvantage to having unlocked bootloader and relocking often results in problems,. I have read of people recovering from this after contacting opo CS so that would be my advice

Hi, this is my first post but I had a similar problem after flashing H2OS and relocking bootloader. I solved it by holding down the power button until the white LED went out and then I booted into fastboot (power + Vol up) . from there I unlocked the bootloader and since then the phone seems to be working fine.
I hope that helps, at least in the short term
I am using OnePlus 3 with TWRP recovery and H2OS.

try re-open bootloader and flash last image(or try with old verrsion like MM)

I try but flashing the first 7.1.2 image but the phone still bootlooping so I let it bootloop all night long and this morning, I'm able to configure it (because of the factory reset).
I hope I have fix the problem.

Bad luck. After setting Android (email, Wi-Fi, ...), the phone start to download apps and then reboot and bootloop
I have flash Marshmallow 6.0.1 but still bootloop.
And I can't enter download mode to try flashing TOT file.
Don't know what to do, apart buying a new phone.

HTC 10 boot loop

Tried so many things and read a lot of threads..
Battery just died and when I tried to start it up, just goes in boot loop.
Only place I can get into is the bootloader (white screen). Unlocked and S-on.
Have TWRP and rooted rom..
Won't go into download mode or recovery..
Anyone any ideas?
Possible to kinda make it 'stock' anyway to give it back into warranty?
Thank you..

Joined the bootloop club, what can I do?

5x got hot and turned off. Won't turn back on. Am I screwed?

Well, hope you have your bootloader unlocked or some sort of warranty, otherwise you're gonna have a tough time flashing custom boot images.

Bootloader is unlocked and I have twrp, no warranty. I flashed but it freezes mid-boot or doesn't power on at all.

Which images have you tried? The only ones that worked for me was the Oreo 8.1 update, after that the phone ran smoothly.

I'm going through the same problem, here are few symptoms : 1. Phone doesn't boot. It gets stuck between boot to doesn't boot at all.
2. I can access boot loader but cannot flash recovery. The phone dow not boot into recovery.
What should be done? Any help is appreciated. Thanks!

Search for 5x bootloop fix here and elsewhere. Was heavily covered when it was really bad starting around June. Too many things to try to repost, like putting it in the freezer for a while to get it to temporarily boot.
Try this fix which disables the big cores if you can.

Phone won't start but it keeps booting to TWRP for some reason.
