LG G4 bricked?

Hello,
After installing the Marshmallow update proposed by lg bridge my lg g4 h815t (from Hong Kong I think ) don't start any-more , I have a black screen and apparently no download mode just the notification LED that flashes and sound of a tap on screen that repeats every few seconds , is my g4 bricked? Unfortunately, the phone isn't under warranty so if you have a solution please help me.
Thank you in advance.

How to turn back from h818 to h815 recovery!!?

PLEASE ANY HELP!!!
I have LG G4 (F500S) version
first i had ILAPO problem after upgrading...i used a method of disabling big cores but i had to choose TOT for H818 since TOT for H815 didn't work (WORKED!!! PHONE BOOTED thou i had to remove battery and plug in usb cable to phone, after NO BATTERY icon appear returned back battery and press VOL DOWN + POWER and remove usb after LG LOGO appear then phone boot successfully )...
after solving a problem of ILAPO i had another problem of VERY WEAK network signal, so i decided to change another kdz (H815)
now my phone has changed from 815 to 818 but whenever i try to boot it i get a blackscreen thou i can hear it booting...then after searching my IMEI info i found it is F500S i am a bit confused on what to do now!!

Same problem
