Bootloader Unlock Help Lg G4 H818P - G4 Q&A, Help & Troubleshooting

Hello everyone,
I have a rooted LG G4 H818P v10k and wanted to install a recovery tool such as twrp but after digging around a little, I noticed that my bootloader is locked and LG supports unlocking the bootloader of the H815 variants only.
The part thrat confuses me is, does having a rooted device imply an unlocked bootloader and if not how can I unlock my bootloader.

How did you root it?
The lg h818p is impossible to root. You're a hero

your phone is locked for bootloader so no twrp yet.
for root you have use or someone a system.img already rooted. and replace it and phone is rooted as long as you in lollipop you can root.. so nope. you or someone just pushed the rooted . img into phone with commands. so no unlocked bootloader.

For LL you do not need an unlocked bootloader for rooting. For MM you need unlocking to root. The reason is that LL allows system modifications. MM not.

Sorry but that's wrong. There is TWRP available for his device. TWRP in FIsH.

Since you've alread rooted, did you try to install twrp from an android root app such as
Rom installer or flashify
This might work.

Tell me Sir,
What can you do with TWRP-in-FISH without Efidroid? It's like a car without an engine, right?
Correct me if I'm wrong.

you're just kicking in to every post you find just to either useless comment or asking questions which are already answered right?
TWRP-in-FIsH seems to be useful for many ppl out there which you may not understand because you have an unlocked device.
... if you ever would have read (and understood) the TWRP-in-FIsH thread you won't even ask those above questions.
Efidroid has nothing to to do with TWRP-in-FIsH.

Check out: Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks at https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
It's all there - all you need is to 1). ensure that your current stock rom does not have an anti-rollback provision that would prevent you from downgrading from Marshmallow to Lollipop (LP). Use LGUP-NEW for the downgrade - it will throw up an error if the anti-rollback provision is in effect and 2). obtain a stock LP version for your exact phone model (and a pre-rooted version, if one is available).

I checked before I started rooting, but the software version off the pre rooted version is 10D
Mine is, 20h but I'm not sure what will it be if I downgrade to LP

You are on Marshmallow with 20h. Your software version will be 10D (Lollipop) if you use that pre-rooted kdz. It will work if it's for your exact phone model ... However ...see if you can find a 10n or higher version. The 'h' LP version for some models do not have the latest stagefright vulnerability patch, 'n' versions and higher do. You can use the Stagefright Detector app (free on Play Store) to check if the kdz you choose has the latest patch

Will it effect if I get the same model but different software version?
I tested it and it said it's not vulnerable

Other than having the latest security patches and any added upgrades to the firmware, it shouldn't.

O.k. cool
But I had a problem finding a 10c kdz for my device
Do you know how to get one?
I need it cuz if I get a 10D or later, my phone won't accept to flash the root

[Q] How to root LG G3 D855 on Lollipop.

I was wondering if there was some method for rooting the LG G3 on Android 5.0 (Lollipop). I've searched far and wide on the internet but have found nothing so far. I did see that there were methods for the Nexus devices but nothing for LG.
Would like this as well. I thought I could live a while without root.. Seems like I just can't. :crying:
I think that you can find already rooted lollipop version on the forum.
For now, i nowhere found any root options.
Sent from my LG-D855
now it's impossible to root lollypop via purpledrake, ioroot or other programs but you can flash a rooted bumped rom.
I'll wait for this.
Same situation here.
Planned to use the pre-rooted lollipop but to use it you need twrp on the phone. To get twrp you need first root. So its a dead end, a points on b and b points back on a, both needing the other present first.....
Maybe if you flash an older kdz, root it with any of the previous methods, then get twrp on the phone and then flash the pre-rooted lollipop. Im just gonna wait for a lollipoproot without twrp needed.

I am on 5.0 and tried purpledrake (since i used it with 4.4.2), but it did not work, i also tried Stump and got an error too. With 5.0 the structure has changed and the methods for KK are different to Lollipop. So far, even with Nexus, the only way to root is through bootloader/kernel.
Hopefully soon we will see a method that can bypass this.
This is the method that works on the d855 by skin1980 - http://forum.xda-developers.com/lg-g3/development/rom-lollipop-rooted-rom-skin1980-t2936022

Yup, thats the reason why i downgraded it to KK. Downgrade, root and you can install rooted L.
Sent from my LG G3
Does that work then? I'm on Lollipop 20a on the D855. If i install the KK kdz, will it make the phone rootable again? I read something to do with the boot loader not reverting back to how it was before lollipop

(you can flash almost any KK KDZ, v10x of course, but make sure it's for your device)
Root it with your preferred root method (i prefer Purple Drake)

Now you can flash the bumped roms you'll like. Just make sure, it's for your device.

You cannot install a Custom Recovery on the 815P due to the Bootloader being locked and LG has no plans of unlocking it so the best option for you is Flashfire (in the play store). You have to be rooted though.

What? H815SEA and H815EU are both international variants but only H815EU can be unlocked.
The best method is to flash boot.img unpacked from the custom kernel like SimpleGX via fastboot that will allow you to further flash TWRP in which you'll flash full kernel package to avoid software problems and lastly SuperSU
the method i followed was-
1. boot into twrp recovery with adb command(you need to have the twrp.img file in PC and also copy it in internal memory of your phone with SU)
2. flash systemless root with twrp
3. reboot
4. install flashify
5.flash twrp.img from your phone.
6. done
but there aren't as much benefits of rooting as any other phone. viper4android doesn't work. spirit fm doesn't work. xposed doesn't work properly.(these 3 were the main reasons for which i rooted)

The vs986 has a locked bootloader so there is no custom recovery possible and therefore no custom ROMs. And it is very unlikely to ever get an unlocked bootloader.
You'll have to stick with just root. Install Xposed and customize your phone as best you can.

Do you mind giving me the link? Also with the newest update can this FlashFire work with it. Because the seller I always buy from always updates the phones to the newest version.

Is it possible to root LG G4 Nougat?

I've had my G4 for a few years now and I've recently decided to upgrade from H818P 5.0 to the v29 ported for H818P
I would like to ask, is there any way to root this version?
Thank you in advance

Refer to this thread under Proofs: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU
"The only device which is a real special one because of different hardware (2 SIM slots) is the H818 which can be unlocked but has issues (see above)"
This is the above:
H818 (KNOWN ISSUE: TOUCH STOPS WORKING!
To date, this has not been solved and may not ever be. If you can live with out touch (highly doubtful), then go ahead, revert back to Marshmallow and unlock your bootloader, install TWRP and install the Nougat stock rom in the Downloads section and then root ...
If not, the answer is basically No. Your alternative is to try and sell your H818P and get a G4 that can be unlocked ...
