We both have the same problem. We both have partition error and unable to boot the phone and causes the hardware to malfunction. We also don't have IMEI which I used the lgflashtool and stated null. So we have to wait for a really good solution to unbrick this hardbricked phone

H818P for now. If your phone is similar to H818P and you could successfully flash H818P firmware in your phone. You can use the patched aboot.

Yes I can do that.. Let me try and update you. Thanks again

i will test it tonight but the Q here can i relock the bootloader or what ???
oh and thanks man for your hard work i thought that i will wait for ever for the unlock.

Can someone give an example how to find Out what to Type for "<your aboot partition>" ?

pvineeth97 said:
Hi guys!
Disclaimer:
No more secure boot error!
I thank my friend @cerg2010cerg2010 for helping me out in patching the aboot.
-> Requirements:
LG G4 LGH818P
Rooted Phone
-> Steps:
(1) Downgrade to Lollipop version of the Android. Download here.
(2) Root your device.
(3) Download the patched aboot file. Click Here.
(4) Connect your phone to the computer. In command prompt, type "adb shell".
(5) Transfer the aboot file into /sdcard/ folder.
(6) Type "su" to enter the root shell. Then type "dd if=/sdcard/aboot_237568.bin of=/dev/block/<your aboot partition>".
(7) Restart your phone by typing "reboot".
You have unlocked your bootloader!
Refer Notes for more information.
-> Notes:
1) The aboot_237568.bin is the patched version of aboot partition of your device. Secure boot validation has been patched such that secure boot is always valid, so you can flash your own TWRP and Custom ROM.
2) Don't upgrade to any updated version of Android if you get any through OTA update. It might brick your device.

Sounds amazing. Please provide the details about the patch meaning what have you done exactly to get that patched aboot?
Could you please download my latest TWRP beta(!) and provide me the recovery log? Or someone else of course
My latest beta is a unified variant and so should work for h818 as well but maybe I need some small adjustments..

Well I have to say I'm impressed. Share your method with us and spread unlock for all variants! G4 might finally reborn!

When you flash the patched aboot, the bootloader is unlocked. You don't need to do anything else.

Patched the secure boot validation function. The patched aboot has the secure boot set to always valid condition no matter what image you flash.

And after flashing KDZ the bootloader will still be unlocked ?

Proably not. Aboot is part of kdz flashing.

This is fantastic news! H812 user from Canada here hoping you can make this patch process work for our aboot too!

As in case of g flex 2..
Everyone be warned..
The aboot on lg k10 is not signed
But in lg g4 there is a hash verification to aboot.
It may result in a hard brick.. so be warned

first of all , thats great news. this is the same method we use in h815 with the unlock.bin from lg but instead of pushing the file directly, we flash it in bootloader. clever and nicely done.
since its public you should share it the right way not like this. i mean this is not a development project, this is about unlocking and flashing twrp. it should be a DEVDB thread in general under utilities section so that everyone can find it. Also the title should be: "Unlock Bootloader H818".
As it is, in a week or two its gonna fall at a second page and in search results also almost noone is gonna find it cause of the title.
in the op tell them about mmcblk0pX. They are not all expert , they don't know mmcblk0pX in g4 is like our sdX in linux.
Tell them the ls command to find which mmcblk0pX is the right one or how to find it with a root explorer. As it is, its just gonna give them an error and gonna ask you everyday about that.
We need h818 users too. To be able to start developing for more variants its important. Cooperate with steadfasterX to correct bugs in twrp (if there are any).
This would be the 1st step to start flashing together with us , custom roms.
Finally , Welcome H818 users

if the tot or kdz are for H815EU, then it will works for any other H815x (including H815p).
I'm a H815p's user too.

AFAIK, the H815p don't have anti-rollback... so you should have ARB v0

Hey..
I have exact the same Problem while upgrading to 7.0 via tot File. After update stucks after 21% and get same error - 0x2000 invalid command response.
After Battery pulling i´ve used LG Bridge in Software Update Tab and use Correct update error, but LG Bridge tells me there is no Update Error, my System is up to date
I changed some LGUP 8994.dll files, there are some out there...nothing is working.
Try to "downgrade" H81520D_6.0.00_0115.kdz via LGUP, but after 21% it fails too.
So, what next ? Any one a working Idea for me ? Thank you.

Hey the_naxhoo !
Thank you for Helping, 20p was my Key.
I´ve flashed the H81520p_00_0314.kdz.
There are some 20p Versions out there and tested them all, but only the H81520p_00_0314.kdz was worked for me after i´ve extracted the LGUP_8994.dll from the H81520p_00_0314.kdz file with the Tool Windows LGFirmwareExtract-1.2.6.1
Puhhh, i´m so Happy now.
Thank you all PPl here in XDA and wish you all a Wonderfull Christmas !

LG H815 - error on every firmware
Hi guys,
I have same problem, already been through all the solutions that I have found, including H81520p_00_0314.kdz and replacing DLL from this firmware. Still got error 0x2000 :/ Any ideas? I have checked mainboar and model is H815 without any letter after.
OK, some update - extracting DLL helped, I can flash firmware, but phone stucks on LG logo and don't want to boot up :/

Hello,
Thank you so much, this method worked - H81520p_00_0314.kdz.
Now how can I install another version of android 6, which is officially in Romania? I honestly do not know which version I should install! (V20?-EUR-xx)?
Please give me all the steps to follow to install an official version.
Thx.
PS: my phone is LG H815 International version, Carrier less.
