Time to root my LG G4 H-815TR v20i. What do I do?

I have boringly used an LG G4 for almost two years now. Just after a few months of using it, I had the bootloop issue, LG gave me another G4 which I've been using for more than a year. But I believe it is time to unlock the true potential of my phone. I've transferred all my pics and vids and similar stuff to my computer, so now it's go time. The only thing is... I don't know what to do.
Model number: LG-H815TR
Android version: 6.0
Android security patch level: 2017-03-01
Kernel version: 3.10.84
Build number: MRA58K
Software version: V20i-TUR-xx
These are the info I think are relevant. I have no experience in rooting whatsoever. What do I do now? (an up-to-date detailed guide also works for me)

Hey,
I still need help for this.
I've checked online and couldn't find anything for H-815TR v20i running Marshmallow.
Can someone come to my rescue?

It's very easy:
You can't unlock your device because LG allows unlocking of the 815 international version and 811 only.
Marshmallow can be rooted on unlocked devices only (so not on yours).
If you really need root you need to downgrade to lollipop.
Downgrading to LL requires a compatible anti roll back version. Search the forum for the code which displays your current antirollback version and the how-to for downgrading and rooting LL
.

Oh okay.
So I can't root my phone as is, I need to downgrade to Lollipop to do that.
Well I was thinking of flashing some custom ROMs and maybe underclocking for more battery life but given that this is my only smartphone I'd better stick to its current state then.

find the service menu for your phone. Google lg g4 service menu. call that number. check anti roll back version (last entry) if 0 you should be ok to downgrade, if not 0 downgrade will likely brick your device.
https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
read carefully and ask a any questions before using LGUP if unsure
after that you can root with https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
or upload your img file and kindly ask someone to root it for you and re-upload it

Anti-rollback version is 0.

you need to go into hidden menu. and go to software and look at antirollback.. am no t also sure but seems a 0 means you can if it has a number like V1 V2 V3 if you in V3 and lollipop is in V1 wich ithink it is. cant.

maybe your phone its not a h815. says it is but motherbpard could be another variant. maybe am just guessing . but could be the reason.

I'm having the same problem with my LG G4.
It has the software version V20d-GLOBAL-COM.
I've seen that someone has solved it by updating via LG Bridge. But when i tried that it always says "Cannot check the software version. Try again.".
Can i just update with LG UP to V20G-EUR? And will that solve that problem?

Exactly the same issue as the topic poster with a recently received refurbished LG H815 (from Aliexpress), the blue case uncheck right after I tick inside. the case.

So it is impossible to enter fastboot in Adb command (I want to install a custom recovery as TWRP), what is quite strange is that Adb (when typing "Adb devices") just see the device as "LGH811xxxxxxxx device" ... Why LG H811 if it is LG H815 ???
I tried everything, messed up with many Adb interface drivers for windows.
Even tried to flash to Stock Rom with LG Flashtool and LGUP, by downloading LG H815 TOT files and KDZ files...and neither it is working.
Should I try with LG H811 TOT files and KDZ files...each file is quite big (1.6 Gb) ? And where to find reliable related files for H811 ?
Thanks for who could help us....

I have just found a way, just published it..

I loaded combination file and it's booting but what to do now ? Cant find FRP bypass file for A320FL. Can you help me ?

Oryginal firmware was adroid 7.0 A320FLXXU1BQH7 all what i found was A320FLXXU1AQA3 i fleshed its working just can't unlock it. Any tips what to do now ?

I didn't have combination file for this version but i downgrade to androi 6.0.1 and i made some trick with keyboard asist can find at youtube.
But after this can't update phone shows phone up to date (android 6) samsung kiess sa,e. So i used odin to flash 7.0 and wiped cache partition + factory reset and still doesn't show updates, why ? Maybe wrong firmware region ?

I would recommend to use z3x support to bypass your lock code. This activation works with almost all phone models. You can read more about it at https://gsmserver.com/gsm/credits-and-activations/. I am sure that it would be helpful for you.

What device is that for? I've never seen that number before.
I just checked Motorola releases, no such firmware is listed.

That's not a model number I've ever seen. Moto G6 play is xt1922- (7, 6. 5, 2, etc) from settings-system- system and hardware.
It looks like aljeter but the numbers don't match anything I've seen.
Build number has no matches.
What update channel, and actual model?
How are you getting the model number? It's in the about phone section of settings.
Is that the boost model? It looks like output that I saw from another person.
Are you using a dongle (smartclip) to try to sim unlock it?
Probably not going to work. And I know of no such firmware for this phone. They're not named that way.
Looks like output from an unlock dongle. Probably need to ask in the place you got the dongle.

If you're sure it's the boost Mobile model, you can use the Sprint firmware. I'm not sure what actual build number you're on. But you can always try the latest firmware, which is pie.
these are all the Sprint firmwares.
Boost uses Sprint firmware.
