Soft bricked - flash stock

I have a G3 that I tried the 1 click root method on. It said it was successful but on reboot it is stuck at the LG logo.
I am trying to follow a guide to flash the stock firmware. (androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants)
Can someone please tell me whether the guide is still good and whether the link it directs to (androidrootz.com/p/lg-g3-stock-fiwares) is where I want to get the firmware from? It seems to be over a year old at this point.
Also I am a bit confused about which firmware I want, I thought my version was the D855 International version, does that mean I can use either the D855 EUR or HK firmwares?
Sorry if some of these questions are obvious, got the device yesterday and it is my first Android phone! Also sorry the links are clickable, I don't have 10 pots yet.

Got it back to 4.4.2 using the aforementioned pages. Flashed the European firmware after reading some stuff elsewhere.

H815P Root Method?

Hi guys,
I recently got my LG G4 replaced as there was a software issue on my old one (which was rooted, Android 5.1), and the replacement model has been upgraded to Android Marshmallow. It's an H815P model (as was my old one, I think I used LG UP to root it, as there is no unlocked bootloader for it). I'm not really sure how to root my current phone, and was hoping I could get some guidance? Sorry if it's been asked before, I'm not the most well versed with rooting.

Find the appropriate LP KDZ file for your phone and then use LGUP and downgrade back to LP.
I did that late last year sometime.

Full g5 systemui and framework for lg g3

I got my lg g3 fixed running v30b and i rooted it got all the lg g5 apps but i dont have custom recovery so i cant flash a rom and everytime i replace the framework and system ui from the lg g5 it gets bricked and i have to flash a new kdz so can someone help me? Please

what the.... why are u trying to port framework without a custom recovery? it's not hard to install there is a program called g3 autorec that you can find online (not on playstore) that will install an old version of twrp for you and backup your current recovery, just make sure u get the right one, there are diff versions for diff g3 models.

First downgrade to kitkat (with a d852 tot or kdz), then root, then use autorec. After that you can flash what you want.

Pretty sure you just did something wrong. You say your device is a D852 (from your software version), the fact that a D852 kdz or tot is not compatible with your D852 because it was manufactured in 2016 is very unlikely. You also said that your motherboard was "fried" when you tried to downgrade (which is again, VERY unlikely), if your motherboard was fried you phone would be dead right now.
"now i want you to ...(blablabla)", don't ever say that if you want to get some help.

I said it was unlikely that the kdz or tot wont work because your phone was manifactured in 2016, not that your phone was manifactured in 2016.
That being said, I guess you don't understand really well english and that's causing some misapprehension.
I was not rude or anything, I was just trying to help you.
Have a nice day, I wont answer anymore.

I strongly recommend this thread is closed.

LG-G4 us991 downgrade to lollipop?

I'm trying to downgrade my G4 from marshmallow back to lollipop. My anti-rollback # is 2, and according to this as long as the anti-rollback # is the same on both the installed version and the kdz, flashing the downgrade doesn't hard brick the device.
So far I've been unable to either find one, or clarify if one exists for my variant or not. Can anyone help? Thanks.

In any event ...

In any event ... if you do happen to find an LP stock image to try, make sure you use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to downgrade to the stock Lollipop image as it should throw throw up an error regarding the anti-rollback version roll back and not proceed with the rollback, thereby avoiding any brick worries for you ...
You may have to do a bit of trial and error but it would help if you post your exact software version that you are on now for anyone to assist you in at least pointing you in the right direction for LP kdz's to try.

Oh, so LGUP-NEW pretty much let's you throw any kdz at the device and if it would have normally bricked the device, instead it comes up with an error? That's pretty neat.
My specific software version US99125a, and if it helps at all, my end goal is to hopefully root my device.

Well, not any old kdz ...

Well, not any old kdz ... You want to keep to US Cellular versions. This site lists a couple of LP kdz's:
https://boycracked.com/2016/10/14/official-lg-g4-us991-us-cellular-stock-rom/
I suggest you check out: [Discussion] US Cellular us991 at https://forum.xda-developers.com/g4/general/cellular-us991-t3151051
read the posts and then post any questions you might have there and google XDA - LG G4 US991 for additional input.
That's all I got for you ...

LG G3 D855 root problem

Hello!
I've got a little or maybe a big problem with rooting my LG G3. For now i've got android 6.0 Marshallow installed.
I spent on this whole day and I think i tried every possible way.
I tried stump root(i guess it only works for kitkat) , purpledrake root, kingroot..
Moreover I tried to downgrade to android 5.0 but my device is "unknown" for LG UP. Also, I tried LG Lash tool but it returned an error too.
Do you guys know any other way to root this device? Thanks in advance ;c

I got the same problem.

Hi! Sorry that I'm responding so late. I found that i had the problem with downgrading becouse of wrong LGUP zip.
I found correct one here https://www.youtube.com/watch?v=81kb6fqHxUo&list=LLF_c9VT9RRrxMaH_s9qwFWQ&index=1&t=283s in video description.
Now with LP installed root should be possible.
