[E 2015 General] AbrOXEr:
bricked device, need help

Hello guys. I did the most stupid thing which i could. I tried to flash xt1526 USC with xt 1524 firmware without unlocked bootloader and without checked (allow oem unlock) setting in dev options. So flash of course failed and i also can't unlock bootloader.

I found the firmware from boost mobile which i could flash without errors that is

"SURNIA_BOOST_5.1_LPI23.29-18-S.11_cid9_subsidy-DEFAULT_CFC"

But after flashing and pressing "start" or rebooting device or "recovery" all i can see is black screen. It looks like phone is switched off. Could someone tell me is this hard brick or there is a small chance to restore the device?

Here is the log of flashing process:
