I should of been more clean in my Question.
The EU Lg bootloader Unlock that is available. would it work on the 815K compared to just a 815 or 815EU.
As far as i can gather from the state of these threads the phones are the same. (besided bands you mentioned) when it comes to unlocking the bootloader.
~Thanks in Advance.

Unlock only works for 815EU models currently.. No other models are supported/unlocked...

[LG-H81220U] I want to downgrade from MM to LP so that I can root my LG G4 (H81220U)

Hello, I want to downgrade my LG G4 (Software Version: H81220U) from Marshmallow to Lollipop so that I can root my phone. Could anybody guide me to achieve a downgrade AND a root? My carrier is Telus/Koodo in case it's relevant information.
Thank you in advance

first you need to nkow if tou can as in some models antirollback changes and makes it imposible to downgrade. so first make sure that antirollback versions they are if the same then you may if different then youll hard brick phone.

Hi @syphlect
Did you manage to downgrade it?
Have searched all the forums, did not find a way to root the LG G4 H1220u Koodo version.
let me know if you found any links

Use ...
Use ... LGUP - NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to downgrade from MM to LP. You want H81210 for your Lollipop KDZ. Once you've done that, you can install a pre-rooted image (easier) or root your own extracted KDZ. Note: You will not be able to obtain root through any of the Root-Apps - check out the link in the next paragraph for the general how-to for the H812, if you have not already done so.
Refer to [Canadian Guide] - Complete Source for the LG G4 H812. Linux VM/Root/Tools&Files at: https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449 for the how-to on rooting the H812.
Follow the Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks (https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586) ONLY for installing the rooted image and use the command for the H812 model in the 2nd post here: https://forum.xda-developers.com/g4/...ot-lg-t3164765 found in the following box: Command to Flash System.img (All Variants):
Once done, because you still will have a locked bootloader, you will not be able to install a regular version of a custom recovery or flash a custom rom (that may come eventually when efidroid is managed to be ported to the locked LG4's). However, you will be able to install a non-regular version of a custom recovery with TWRP-in-FisH that has been tested on the H812 and is working just fine with Version 3 Beta 4 and 5 (you can find those links in the later posts in that site): [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048
Good luck.

See if you can ... find KDZ's that that are particular to your region in the event there may be differences in bandwidths that are operational, etc.

Yeah could not find specific to koodo Canada. Need to see if its safe to go with something similar to it.
Also I see my current software version is H81220Z. It got updated overnight even though I un-checked to install updates automatically.
Will the LGUP process still work to downgrade?

Koodo is on the ... Telus network. You can use Telus KDZ's (doesn't specifically have to be H81210Z and they seem to be available (check the Canadian Guide) - others have indicated you can use other Canadian providers (read the Canadian guide). I can't confirm this personally.
Use LGUP-NEW for sure as you are less likely to brick from what I understand if an anti-rollback provision has been put in on the latest firmware upgrade.

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
.
Sent from my LG-H815 using XDA Labs

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.

theres antirollback version .. find out what antirollback you in.. find it using the hidden menu code. for your phone. check on software and bottom antirollback.. theres i beleive 0-1-2-3.
if 0 i beleive that means thers no antirollback if on 2-3 then if you are on 3 and lollipop its on 2.. then you cant.. so check on whats your antirollback. and if you can downgrade.. then if you can download your variant KDZ file and LGUP to flash.

It sounds good to me, but when I felt the impossibility of not being able to downgrade I was forced to sell it as a tmobile device, since for some strange and not logical reason, it did not register on the sprint network in any way and the only option that sprint gave me is to send it to warranty:crying:
