Should probably know what you're doing before you do it..

Hello may be i can help..
First tell me are u familliar with recoveries,flashing,boot etc
Do u knw how to get to recovery mode in lg g4?
The most simple way to root ANY DEVICE is to use vroot.apk. it can root almost evrery device. Downliad it fro google not from Playstore.try itand tell me if it works.or if not works u can try iroot version of v root for computer windows.

Don't **** with your device if you have no experience with root. Your version H818, as far as I am aware; has not been unlocked or rooted yet.

I have rooted most all of my android phones in the past. I am no stranger to rooting and messing with my phones. I was just looking for help with my phone from a better mind then mines on this one. Ive never used an unlocked device before. And yes the bootloader is unlocked.

Well it's not, as the only device that can have the bootloader unlocked is the H815 EU unlocked variant. The is no way to unlock bootloader and fit any other variant yet.

It is the EU VERSION

Softbrick after downgrade

in device manager qualcomm hs-usb qdloader 9008. how to fix?

Had someone I know have this happen. 9008 is an emergency mode. They weren't able to fix or get any information in or out of it. Some information found was to jump an IC connection on the board, but this is not recommended, will void your warranty, and the diagrams for this device cost more than it's worth to get it replaced.

need AP files for BoardDiag from MSM8996, where i can find it?

no one come across such a problem?

Nothing yet?

I have a phone in my hands, can I help to speed up the solution of the problem?

Any help ???
i have same the problem !!!

also i have the same problem??!!!!

no, the problem is that i flashed a wrong firmware on my mobile and it ends with a black screen and no power either
I couldn't find a program such (boarddiag) can deal or recognize MSM8996 LG RS988 processor.

If u plug it to pc. Does it show qusb 9008. If so its hard bricked. I dont believe there is a method for repairing that either

hope someone can find solution for this as my phone is still new

Eventually. Some one will. U will need the orig firmware it was on so if it was on zv8 u need zv8 tot lg firmeware extractor and diagtool. To extract zv8 or which ever u were on orig only. To make a debrick image. Then we need a firehose.bin for qfil in qpst. If that method will even work for g5. It was touchy on g4. But worked on all but sprint i think just because we had a outdated firehose.bin file. I made a few debrick .imgs for g4 but again were basicly useless withouth the firehose bin. If u could find that there is a chance. Now if u were on zv9 or zva as of rite now ure outa luck. Thank sprint for that not releasing those .tots yet

You might have more luck in the LG G5 forum than the Sprint LG G5 forum. As you have the American unlocked model you might have more luck finding a solution there.

Plug your phone to your PC, and start LG Bridge to check for update.
LG Up also works, but you'll have to find a corresponding KDZ( not that easy )

Get LG Bridge from here: www.lg.com/hk_en/support/support-mobile/lg-H815T
Don't flash other variant‘s KDZ，or you’ll risk BRICK your device or get a null IMEI
H815T is not a common device and there're HK version and AUS version,use LG Bridge for safe.

Ok thank you... One last question Can i use cyanogen mod rom?? If yes which one?? I will b greatly in debt

no i think your phone cant be bootloader unlocked.
you cant root MM only LP thats why you had it rooted.
LP and MM system is different and on LP there was a hole that you could xploit it to rooted this changed on MM. in blocked.
so only in LP can be rooted with locked bootloader. wich am 100% your phone is. also if you plan to go back to LP make sure to know wich antirollback you are because different antirollback hard bricks phone..

still haven't managed to update mm... update file downloaded (1.67 gig~..too slow connection 4 hr to download this file) it started updating went to 9% than phone restarts into download mode and error pops up in bridge saying report recover error
can i download the update manually AND install it because stock downloader takes too long (normal downloading @150~200 kbs/s when my peak connection speed is 500~600 kbs/s)

update ** now my phone doesn't show up on my laptop anymore ****

Hello, same problem here, the official website giving a bad end, so I have tried the xda tuto here : https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586 but for me it fail to the step 1, directly fail or infinite wait for the system.img backup so I haven't tried to flash...

The only ways to achieve root on a H815 SEA are
USU method steadfasterX USU unofficial bootunlock
Downgrade to Android 5.1

Ok thanks, I will try this week end

I have tried to downgrade to lollipo last night but my device will however stuck with the message at lg up saying "invalid command" tried other stock firmwares from the cow storage but still the same problem pop up. Lastly i use lg bridge to recover my device. Seems like all the firmwares in storage cow are incompatible with this variant.

IIRC, its recommended to stay on marshmallow when using the unlock as those who unlocked using lollipop faced lockscreen and a few other problems.
