Help with a bricked phone

[inssain]

Hi,

My phone is stuck on a bootloop and I am not sure what I should do to fix it. Any help is appreciated.

The boot screen shows:
** LOCKED **
*** Security Warning ***
M8_UL PVT SHIP S-ON
HBOOT-3.19.0.0000
RADIO-1.29.2145002111G
OpenDSP-v51.2.2-00593-M8974_FO.1015
OS-6.13.666.7
eMMc-boot 2048 MB
Dec 14 2015,17:15:5.0

I have tried selecting the factory reset option and it doesn't help. I have also tried going into recovery option and it takes me to the red triangle screen.

Any help/suggestions are appreciated.
