Hello, with this method, it may be superuser on devices with MM and locked bootloader?

MM Root it's not possible in any way locked bootloader devices. only way unlocked bootloader and custom kernel. Stock kernel root impossible.

Thanks for the reply.

It is knowing that commands operating in MM, thought he could do the same in LP, have root eventhough have locked bootloader, all for ADB commands.

"I die" wait to unlock my bootloader; but my model is not unlockable officially. H815P

I understand the language. It is indeed instruction to get root on MM with locked bootloader. Only tested on f500 and OP is the only 1 with success so far. Lets wait and see if more will come up

Edit: this is NOT root for locked bl on MM. OP just made it clear to me on the other site

No. Currently and for the forseeable future it is NOT possible to root Marshmallow with a locked bootloader.

Do you want me to quote all three posts again?

Root on Marshmallow requires a modified kernel. You cannot boot a modified kernel with a locked bootloader.

Rapunzl · Mar 11, 2016

I don't know about other models, but H811 allows you to unlock the bootloader and root on Marshmallow, but it's not via supersu injection.

Well months have been passed. Any news about to root H815P? I still have my Bootloader locked and LG's site says that my model cant be unlocked. Any idea?

TheMadScientist · May 9, 2017

Guys. This is for sending files to the phone kinda like adb. Not root. It more like for executing files that are already on the phone.
IN No WAY IS THIS A ROOT METHOD
YOU CANNOT ROOT MM WITH A LOCKED BL. ITS NOT GONNA HAPPEN ANYTIME SOON

Rooting MM with Superuser ...

heros_45 said:

Rooting MM with Superuser ... is not possible with locked bootloaders as Chainfire's method requires modification of the boot partition and that equates to a brick with bootloaders that are not officially unlocked through LG.

Downgrade to LP, root and install steadfasterX's TWRP-in-FisH @ https://xdaforums.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048 if you want a working custom recovery version that will work on LG G4's with locked bootloaders. Version 3 Beta 4 & 5 are very stable - download links are in later posts on his site.

He is working on porting EFIdroid in FisH, that if successful will eventually allow one to boot custom roms, i.e., you may be able to have your rooted MM with a locked bootloader at some point ... just not yet.

If on MM you will first have to downgrade to LP with LGUP-NEW at https://xdaforums.com/g4/help/lgup-install-kdz-mm-lp-t3249803 if you are able to. You will have to search for an H815P10 stock rom. Then see if you can find a pre-rooted image of that rom. You can follow this guide to obtain root or install a pre-rooted image if you are able to find one: Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks at https://xdaforums.com/g4/general/lg-g4-100-root-success-directives-root-t3180586.

If you want a custom recovery for your locked bootloader, check this out by steadfasterX: [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at https://xdaforums.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048

You will not be able to install a custom rom, however, but steadfasterX is working on EFIdroid-inFisH that, if successful, will eventually allow the installation of a custom rom on a locked bootloader.

Hope it helps.

hey guys,
Hope I am not too late, I found a way around this.

What I did was downgrade from Marshmallow to Lollipop.

I did it by using the LGUP program and following this:
https://xdaforums.com/g4/general/fix-unbricking-lg-g4-h818p-stuck-t3707485

In short what I did was:
1. Download the kdz
2. Download LGUP and install it, then the dll thing that comes in the archive.
3. Install LG drivers
4. Put device in download mode by pressing up and inserting a usb cable when device is powered off
5. start LGUP and select "Refurbish"
6. in the path select the kdz (even though its looking for tot files).
7. Flash Lollipop and boot
8. Go back to download mode, now you have Send_Command.exe

Then I flashed "H815L 10F.kdz" which gave me stock Lollipop on 815L. I am not sure where I got it, It was sitting on my disk. But basically anything which has H815L (for the model), and 10 which means its Lollipop should work.

Then I could go in to download mode and run Send_Command.exe

NOTE: All LG G4's (with the exception of H818), can be unlocked unofficially now with steadfasterX's: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU, provided you are on stock Marshmallow and your ARB is less than or equal to 2.

I.E., you can now install a custom TWRP recovery, root and upgrade to Nougat, Oreo etc.
