LG G4 bricked? - G4 Q&A, Help & Troubleshooting

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.

Thats odd was ur phone rooted or runing xposed?? by flashing through lg bridge is OTA so thats why the black screen... Download the rom from below and flash it via lg flash tool 2014 by going into download mode or u could use LGUP

LG G3 D855 Country lock update no update center problem Pls HELP!!!

Hello Friends, i just brought LG G3 32GB D855 model from ebay. The seller says that it is imported from European country and it is unlocked phone.
After receiving i check that their is no ota checker in mobile.
Hence I contact to seller then he told me that i cant upgrade the mobile software. If i do so then i will lose the unlocking and i will not receive any network signal.
mobile will again get lock.
I have an LG g3 D855 .So I have a problem that I dont have any update center - which means i cant upgrade my system or anything. i tried to update from LG suite or the lg mobile support tool but the both failed. another thing to point out is that there is no update center also when I go to "About Phone" tab in my options.

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
