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.

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.

What can you do with TWRP-in-FISH without Efidroid? It's like a car without an engine, right?

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

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)

Assuming that you unlock the bootloader, root the phone and change the splash screen....

If Asus logo splash screen is black your bootloader is locked.
If Asus logo splash screen is white your bootloader is unlocked.

Why do you want to unlock the bootloader?
For the time being, there is no way to unlock the bootloader in MM. May be in the near future.
If you want to unlock the bootloader in MM, you need to temporarily downgrade the bootloader to Lollipop, unlock the bootloader and upgrade back to MM by the patched bootloader.

No.
To upgrade to MM from LP your firmware has to be at least 184.
You can use OTA or download the MM from ASUS site and install the MM in ADB environment with adb sideload command.
Do not upgrade MM via TWRP. MM install package does not compatible with TWRP. However, there is guide to modified the installation script in order to work with TWRP. The guide was written a year ago for Lollipop .
If your intention is to use custom rom in MM then you need an unlocked bootloader with custom recovery like TWRP.
In that case you need to unlock the bootloader in lollipop before you upgrade to MM. Like I said, there is no direct way to unlock bootloader in MM.
If your intention is to have rooted MM, then you do not need to unlock the bootloader.
You do not need to install the TWRP. You can use tethered TWRP to flash the super su zip file.

I answered your question in the other post.
As the title says is it possible to root, install modifications to stock ROM and is there a fast way to revert everything is something go wrong? I'm asking because support for 5X has ended, and I can't permanently unlock bootloader. I don't want to hard brick this phone by mistake and also I don't want just look how this device is being wasted.
So here's some probably noob questions that I want to ask:
1. Can I install TWRP on NO RPMB bootloader and boot it without issues? If so, how?
2. What recovery version should I install 4-core or regular 6-core?
3. Can I root device and hide it with magisk?
4. If an security update appear how to install it since stock recovery is replaced with TWRP?
5. If something go wrong like 2nd death loop how to revert everything? Can I simply flash stock system image in TWRP to "fix" device?
Thanks in advance.
You might try the solution the user in this thread suggested, https://forum.xda-developers.com/nexus-5x/help/rpmb-bootloader-locked-t3481906/page2
So I have to unlock bootloader, then flash TWRP, Super SU, compatible Magisk in one attempt, then I'm ready to go? Will TWRP boot and work like nothing happened?
Sent from my Nexus 5X using XDA Labs
I haven't tried it but based on the steps I would think it should work. It won't hurt anything. It also won't stop the bootloader from locking upon a reboot. But as long as you can unlock it prior to flashing any of the partitions as the reddit thread suggests you could be ok.
Locked bootloader won't allow to boot custom kernels that's sure, but will it boot modded stock kernels from this thread https://forum.xda-developers.com/nexus-5x/general/modified-boot-imgs-android-n-t3495169 since they're stock kernels

So there's still hope, cool! Are there any side effects (will Jolla's multiboot and drivedroid work)? What if device suddenly stop working? Flashing stock image doesn't count since we have locked bootloader, so what to do if CPU die again? I prefer to have an emergency plan just in cause. You made my day. With locked bootloader we can't boot customs, right, just asking because it was possible on my Xperia J.

As long as TWRP is installed and "stuck" (ie: boot directly into TWRP after flash), you can basically flash anything (custom ROMs/kernels etc.).
The worst thing that can happen is that you brick the ROM without TWRP installed and the ROM is bricked/the oem unlock flag is reset (not tripped). Even then there's a .tot file somewhere here on XDA that can recover the phone.
I'm assuming that an upgrade to O is also possible via stock images (unlock bl, flash stock images, boot into O, trip the OEM unlock flag, unlock BL and follow the steps described).

Haven't tried Jolla's multiboot or drivedroid. As long as you can get into fastboot, you can just unlock it again and flash stock (though you will obviously lose everything that's on the device). Haven't tried flashing custom ROMs but as custom kernels are working, I don't see why custom ROMs wouldn't.

In short unlocking bootloader JUST allows to flash system images in fastboot, nothing more nothing less? So if I flash TWRP then Lineage it will boot and work like nothing happened (like on 5X with unlocked bootloader), it's sounds so good that I can't even believe.

Did you then do a factory reset and flash root? That should make it stick. If not, you can always just use the TWRP app to get into TWRP when needed.
Edit: You also booted to recovery straight from fastboot after flashing, without rebooting the phone?

Never tried, but even though root may not be needed, unlocked bootloader probably is. Magisk non-system works by patching boot img... If you unlock bootloader you probably can use it.

You can unlocked bl by official Sony method, then flash recovery with adb. Boot to recovery and flash Magisk.

So, if you was wondering it, no, cant flash it with locked bl.
At the moment Backup ta didnt work, will check that thread
And thanx the help, nice to have you on z1c forum :good:
perfect. thx! i was already wondering, if i had to downgrade my z1c in order to get the recovery back. but now, how i do i flash magisk from here?
when i try to flash, i get an error message saying, that the ftf is in sony elf32 format and that i need bootbridge from @AdrianDC to flash.
anyone ever did that or has a better idea?
just tried it now and ended up in a bootlop
It is many months after this post, but in case this helps anyone, here is the answer.
BootBridge method is pretty simple and it worked for me.
On an un-rooted device. (important)
Just rename magisk zip to "install.zip" put it in a folder called install.
Then with 7zip, create a zip-file, include the bootbridge folders, "META-INF" and "scripts" with the "install folder" you just created.
Then name it "anything_you_like.zip" and flash with TWRP
Basically Magisk is SuperSU alternative and provides SuperSU service for your device. ( roots it )
No problems for me at this point. Working on 14.5.A.0.270 and can also get working on 14.6.A.0.236 but have other problems related to getting compatible recovery on 236.
Eventually in recovery, system mount and unmount break for me, then other mounts eventually fail after trying to get Nanodroid working (My Goal to UnGoogle my Z1c) and can't wipe format or anything (only way to fix is reflash with flashtool)
Deodexed ROM seems to be necessary for Nanodroid and this is causing additional problems for me.
If I have to run with unlocked bootloader, I think AOSP may be a better starting point.
