m9 boot loop into recovery

My M9 has been flashed with Viper ROM for several months. This morning, I rebooted my phone as I usually do (it seemed to be running a little bit slow).
It properly shut down; but instead of booting back up, it entered a boot loop. The screen lights up, briefly vibrates, the HTC logo appears for about 3 seconds, then it turns off and reboots.
I am able to press all 3 buttons (+ vol, - vol, and pwr) and get to the bootloader mode (I think) with options to boot to download & recovery modes.
Any attempts to get to any other mode result in the device rebooting after ~3 seconds.
Does anyone have any suggestions on what to do next? In this bootloader mode, fastboot does not detect it (not sure if it should). I am not aware of any other options.
Thanks for any help!

boot to recovery and reflash your rom or restore your backup

I can't get to recovery. When I try to boot to Recovery, the phone bootloops just before the Recovery would appear.

Possibly bricked HTC One M8

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!

Softbrick Looping? S-ON, LOCKED, randomly bricked itself

I have issue with my HTC 10 was wondering if anybody has any information or is having similar issues;
My Verizon-Branded, Bootloader-Locked, Stock, Un-Rooted, S-ON soft bricked itself...Boggles my mind a bit, a softbrick that rebricks itself before you can boot to any menu that would allow you to fix it.
During normal use the phone shut off and stayed off. I attempted a reboot, but it would stop at the HTC splash screen every time. I can get to the rainbow menu by VOL DOWN+ POWER until nav keys flash 10 times then quickly pressing VOL UP+VOL DOWN + POWER before screen goes fully lit and HTC Logo pops up. At this "rainbow menu" I think its the stock recovery for the phone it lists S-ON, Locked, then options;
Power Down
Reboot Bootloader Mode
Recovery Mode
Download Mode
Reboot
I've tried every option but they all end up in my phone hanging at the HTC Screen and stays there until the battery is drained. I've tried different Micro SDs, letting the phone's battery go to 0%, charging, rebooting while plugged in, ect.
Anyone have any idea or experience similar issues? I know this is a verizon model phone, but I thought I'd have a better chance getting answers if posting here.
Brought it in to Verizon, they couldn't get any recovery mode bootloader mode to work either. Verizon rep talkedt to HTC and they are sending me a new phone. I was curious if anyone else has heard of this issue on the Unrooted, Locked, S-ON, HTC 10.

Bricked

My 7-year old was playing a game on my wife's 3a XL tonight and it shut off. Now it's stuck in a bootloop.
I tried to boot into Recovery, but was greeted with the busted android screen. So I tried to boot into Rescue, with the same result. The bootloader is still locked, so all my attempts to flash factory images or boot into stock boot, I am greeted with the "not allowed" error.
Any ideas how I can recover this, or is it completely bricked?

If your bootloader is still locked you should be able to sideload the stock OTA. I've never heard of not being able to boot to stock recovery either. What method did you use to get there?

When you reach that screen on recovery you hold the power button and tap the vol + button and your options should show up. Just factory reset the device.

I tried to boot to TWRP but couldn't because the bootloader is locked. So I tried using ADB commands to sideload through Rescue, but it only said "error: closed".
Ended up doing a factory reset. (running now)
Haven't seen you in awhile

Well well.... thought i recognized that username. Good to see you again.

Bricked help
I cannot get my phone into fastboot or recovery. It stuck on the white google loading screen loop. I hold the power and volume down and it goes into fastboot but if I release the volume down button to scroll (while holding the power button) it will then go black and go back to the google white loading screen. If I hold down the volume down button and release the power button it will restart back to the fastboot page. If I release both then it will restart and go back to the white google screen. If I do power and volume up it goes to the "andriod no command" sreen then back to the googe white screen. In sum, is my phone recoverable?

When in fastboot, don't hold the power button down to scroll. Is your bootloader locked?

I'm guessing its locked because the phone is completely stock. When I get to fast boot I dont hold down the power button, but if I hit the volume up or down it instantly goes back to the google white screen and starts the loop over.

When on the bootloader screen can you fastboot a full image to the phone?
Said another way, try to download the full Google image.. not the ota... Setup a computer with fastboot and driver's boot the phone into bootloader mode and try to run the flashall.bat

Try-Once in bootloader scroll to recovery and press power button. When you see Android on his side hold power button and press volume up button. You should now be in stock recovery. From there you can adb or factory reset.
Edit- to get to bootloader power off phone then hold power and volume down buttons at the same time.
