To be exact, the device does not boot up, it's just in an endless "reset-hp logo-blue screen-reset" loop.
Found this in HPs forums:
Managed somehow ho power down (or the battery is drained) but have no high hopes.
Ok, hard reset key sequence:
switch down phone and unplugged.
Hold vol up then plug charger: phone should start. Keep holdin till a ! mark appears.
Leave button then press one key once: vol up, vol down, power, vol down
Gears should starting. Let it working and plugged till starts again and asks your attentions
Don't enter insider program, your phone will get AU by itself (it could depends on your carrier, check google)
