Sprint HTC One won't turn on, flashing Home and Back buttons.

[atkinsman]

I was coming from Cyanogenmod nightlies, and was trying to flash stock, but the phone just randomly shut off and it won't turn back on. When I hold down the power button the only response I get is the home and back buttons will blink white for the duration of me pressing down the button. Thank you for any possible help.

Can you get into the boot loader?

Keep holding down power button. Button lights will blink for about 12 secs, then let go of power and hold down vol down until bootloader pops up.

Hi. This just happened to me as well, trying to flash CM 10.1.3 to get a GPS lock from a sense rom. Problem is, I can't get to the bootloader and the menu/back lights don't stop flashing. So there's no point where they stop flashing and I can then use the volume button to get to the bootloader. And they stay lit even when I am not pressing anything. I could use some help here.. hate to think I've bricked this very expensive slab of metal. Thanks.

Same problem.
Somebody please help.
EDIT:
Solved. Bright light trick.
Shine a bright light on it and press + hold power and vol down. Make sure the twin sensors aren't covered.

Thanks guletz - you just saved me a call (or a visit) to the Sprint store.

Will this work (Reset and/or bright light) if the phone is in a call. I am stuck listening to a recorded message and can't hang up

This is also happening to most of the sprint 4.3 custom roms. Not sure if everyone is building on top of the same rom image or fimrware issues...let me know if anyone is getting the same issues after flashing any of the sprint custom roms.
