Bricked LG G2 Mini D620R Locked Bootloader

Hello. First of all it´s my first post. I really don´t know how to do this. But my problem is that I´ve tried to unlock the Bootloader by a aboot.img and aboot4.img files and later flash the TWRP Recovery and the Resurrection Remix ROM. When I tried to unlock the bootloader the phone turned off and it not turning back on with any method. I tried the Download Mode, the Hard Reset mode and the Fastboot mode. Nothing works. I read a little bit I found that the LG Mobile Support Tool will help me, but the phone it´s just dead and the tool don´t detect the phone. I tried to reboot it by adb way but dosn´t recognize the device. I really don´t know what to do. I have the LG Flash Tool and the KDZ but I can´t use it cause the phone don´t turn on. Why can I do?

Thanks to who can help me and Sorry for my bad english too.
