HELP! One will not turn on. Only blinking buttons - One (M7) Q&A, Help & Troubleshooting

I was flashing my One today with a custom kernel. All seemes to go okay. When i rebooted my phone, the screen would not turn on. I tried to enter Hboot by holding down the power button for a minute and then pressing the down volume button, but the lights would continue to flash. Ialso tried using the HTC One toolkit to enter the bootloader though my PC, but it says no device found
Please, please, please help!

which kernel did you install and what ROM are you using?

Try pressing and holding the vol down button before pressing the power button and keep holding vol down

Bootanimation loop

Hello everyone.
I got a new Galaxy Ace S5830i today.
I rooted it and installed CWM (http://forum.xda-developers.com/showthread.php?t=1552792).
After that I did install Retribution beta 4 (http://forum.xda-developers.com/showthread.php?t=1806471).
Then after rebooting I ended up getting a boot animation loop and neither the recovery mode would work nor the download mode.
Could anyone of you please help me? I feel very uncomfortable with a brick in my pocket. :x
I'd be surprised if neither were working, particularly if you are getting as far as the boot animation.
To clarify, to enter recovery mode: Switch off your phone (pull out the battery and re-insert if its looping and the power button won't work), hold down power button AND home/rectangular button AND volume up button. When you see the Samsumg GT-S5830i logo, let go of the power button but continue to hold down the home and volume up buttons for around 5 seconds then let go of everything. Recovery console should appear on screen.
To enter download mode: Switch off your phone, hold down power button AND volume up button AND volume down button. Warning about custom OS's should appear, followed by download mode after pressing volume up again. If this doesn't work try taking out battery, sim card and SD card, connecting USB lead (screen will be completely powered off) and then trying the key combination.

Hold power and vol down until it turns on and once it gets to the lg logo, release the buttons and press and hold them again until it gets to the factory reset screen. Hit the power button three times and it will boot into your recovery

Thanks fellas!
The phone has to be powered OFF for the stated and linked methods to work for recovery access.
To power the phone off (if, say, you're stuck in a bootloop),
Press and hold the power and Vol- buttons for 10 seconds do not release, hold for an additional 3-5 seconds. The LG logo will flash briefly. When the screen is black, let go of all buttons. Now the phone is off, you may process to use the previously stated commands to enter recovery.
Hold volume down + power until the LG logo appears....once it appears release the power button and repress it and hold until youre into recovery... :good:

HTC One only HBOOT working - Vol down and power unresponsive

Good day all,
I have a HTC One M7_UL stuck in HBOOT and cannot enter fastboot or recovery. The vol down and power buttons are not responding so I cannot enter any other mode when it gets stuck in HBOOT. I can only move down by using the vol up button (strange), but cannot press power to enter any of those modes. When I try to reboot by pressing vol down and power, the back and home navigation buttons start to flash and the phone goes straight to HBOOT again. Can anyone offer some help with this? I appreciate.
