HI everyone.
Today, I managed to root my LG G3(D855) that is on the Lollipop version(OTA update).
The reason for this root was to flash the cyanogenMod 12 rom. I found out that I needed a bump'd twrp recovery image which I got from this page:
I tried using flashify to flash this image which flashify claims was a success but when I try to boot into recovery, it gives me a "Secure boot error" message.
does the same methods that apply for flashing custom recovery in android 4.4.2 on LG G3 not apply to Lollipop versions?
if I do a battery pull and boot up the device normally, the device seems to work alright but I can't boot into recovery.
So, please I need help as I want to install this CM12. it bothers me a lot that my nexus 7 seems faster than my G3
-- Problem Solved---
I was able to fix this problem and booting into a custom recovery by going through this thread: http://forum.xda-developers.com/lg-g3/general/guide-update-to-lollipop-root-bumpd-twrp-t3048845
Here are the files I used:
"aboot.img" from a kitkat D855 stock rom. (here is the one I used https://docs.google.com/file/d/0B7fkQwhNpU7YNTdfZUQyZlQzLTA)
oversharpening fix flashable zip (here is the one I used http://forum.xda-developers.com/lg-g3/orig-development/fix-sharpening-mod-script-1-0-beta-t2957648 used the latest version at the time of posting.)
a bump'd twrp recovery image for D855 from here: http://downloads.codefi.re/thecubed/lg_g3/bump/
kikat bootstack from here for D855: https://www.androidfilehost.com/?fid=95916177934540501
after getting all these files, move it to the root folder of your SD card.
attempt the process below at your own risk
Here is how I used the files:
I first used flashify (download from play store) to install the bump'd twrp recovery.img.
Then using android terminal emulator (download from play store) I ran this command
Code:
su [b](no need to retype this if you did not exit from the previous Android Terminal session)[/b]
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/sdcard/lollipop-aboot.img [b](this makes a backup to your Internal Storage)[/b]
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/aboot [b](writes “zeroes” to the partition to “wipe” it out)[/b]
dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot [b](flashes the Kitkat version aboot.img to the aboot partition)[/b]
from this post: http://forum.xda-developers.com/showpost.php?p=59353812&postcount=44
I then reBooted my device into recovery mode which of course now has become TWRP recovery.
in the twrp recovery I flashed in the oversharpening fix.zip file (I was prompted during the installation to choose a sharpening level, I chose 5. this value doesn't have anything to do with the recovery process, we just need it to bump the lollipop boot.img)
After that, I flashed in the Kitkat boot stack and then rebooted my device.
that's it. I am on CM 12 now. Good luck.

I did but it was a very complex solution. see http://forum.xda-developers.com/lg-g3/general/guide-update-to-lollipop-root-bumpd-twrp-t3048845
I am yet to attempt that.
Causes of "Secure Boot Error"
Hi Friends,
"Secure Boot Error" and "Certification Verify" are already "known" errors, and by "known" it means that the causes are already well-established and therefore, can be fixed.
Please visit my thread and read the very first post at Page 1, for the following topics:
1. "The Logic Behind It All"
2. "Troubleshooting and "Q&A"
Heads up: I'm not the type of member who will give a straight answer, so please expect my how-to and posts to be very wordy. I want fellow members to understand what they are doing, not just tell them what they are doing (teach people how to fish, not just give them fish - so to speak).

The explanation is in my how-to thread, Page 1.
I created an easy solution already as well, it's in my how-to thread. I created a script called "Imageprep". It only requires typing a single command in the Terminal. You must have not read the guide fully so you might have missed it. Understandable because you said you have exams.

Very good, @lordzouga.
This is the reason why as much as possible, I explain the logic and force other members to understand it first. It makes the process easier for them because they know what they are doing.
The method worked perfectly after i bricked my device for the 1st time (was flashing the wrong recovery)after it worked i noticed most of the apps i need dont run on lillipop (due to devs not upgrading the apps to run with ART) so i downgraded to kitkat ......tnx alot for ur help
Thanks, this method worked perfectly.

The reason why recovery wont load if you rooted using LG's lollipop firmware is because they patched the hack that bypasses the Security check. You need to downgrade to kitkat or keep on Lg's lollipop

Be careful with this thread, it will brick your phone. On the safe side make sure you remove laf partition and fastboot is working. I got mine bricked.
Does it work for Android 5.0 Lollipop or only Android 4.4 Kitkat?
I'm having problems with the LG Mobile Support Tool. When I try "Upgrade recovery" it gets stuck at "Downloading software..."
It starts downloading fast, but after it gets about 30% or so, the download speed drops to nil. My internet is stable and fast. According to NetBalancer, the LG tool starts downloading at a steady 3mb/s, and then drops to short bursts of 50-150kb/sec. I'm not having any connectivity issues with other programs.
I let it keep going earlier today for almost 4 hours. It got to about 60% and then the tool crashed.
There's been a couple of times it said something like "Please check your internet connection, then press retry." The internet connection is fine, and clicking retry will bring it back up to full speed for a few minutes before it slows again.
What can I do?
What version of Windows are you using?
---------- Post added at 04:16 PM ---------- Previous post was at 04:09 PM ----------
Please don't post about the same problems in two different threads. I'm guessing since you using Volume Up to get into Download mode that you have a VK810 variant of the G Pad 8.3, correct?
If so, try one of the KDZs in my signature for the VK810.4G with LG Flash Tool 2014 (Google for it on XDA). That way you don't have to have a tool re-download the KDZ every time you attempt to recover.
If you want root and custom recovery, it's easiest to get both with the 11A KDZ, then flash my ROM in my signature with the latest TWRP v2.8.7.0. If you just want the latest stock unrooted, download the 36B KDZ.
If you don't have the VK810.4G, don't use the KDZs I link to.

I wasn't sure if this should be considered a new problem, or a continuation of the other. But, I can see how that would split people's attention. My bad.
I will try your steps, and let you know how it goes.
Ok, I succesfully got TWRP and 4.2.2 w/root.
Now I have another problem...
When I flash ViKtory Rom and SuperSU, it will not boot. It just gets stuck at the red Verizon screen.
You mentioned that in your ViKtory rom thread:
5.2.2. One user has verified that on their VK810, that once they flash any version of SuperSU.zip that they've tried, including 2.46 and 2.48 beta, the ROM will not boot. You're ONLY recourse is to get into Download mode and use "LG Flash Tool 2014" to Flash the 35A_08 KDZ, and root it using @Hnk1's thread [VK810][ROOT][Lollipop][5.02] No downgrade required.
Click to expand...
Click to collapse
After flashing, I lose the custom recovery and it boots to 5.0.2 without root. None of the root methods in Hnk1's thread succeeded in rooting...
I did this successfully about 6 months ago, so I know it's possible.
EDIT: I just realized that you said to flash the 35A KDZ, and I used the 36B KDZ. I'll download the 35A one and see if I have better luck rooting then.

Re: 35A versus 36B, I just haven't updated the OP. Actually these days I recommend the 11A KDZ because:
1. 11A through 24B can be rooted easily with the Stump app in brute force mode.
2. 11A is 4.2.2, so the aboot (bootloader) doesn't need downgraded prior to installing the initial Loki'd TWRP v2.7.0.1.
Did you upgrade to TWRP v2.8.7.0 before flashing the ROM and SuperSU.zip? Flashing KDZs always returns your device to complete unrooted stock just like from the factory. You should always use "CSE" mode of LG Flash Tool 2014. "Normal" mode doesn't wipe Data or Internal Storage, but especially if downgrading, you can expect that to cause problems.
35A is just as hard to root as 36B. I wrote that tip in the OP after I thought @Hnk1 's method was more easily reproducible. Sorry for the runaround and out of date directions, but you should go with the 11A KDZ.
If you had upgraded TWRP to v2.8.7.0 before flashing my ROM and SuperSU.zip and still had problems booting, you can try wiping Cache and Dalvik again (after flashing), but I don't expect that to work. You can also use CWM Recovery (just flash CWM from TWRP). There's a thread for VK810 CWM on here plus I think I have it in my VK810 section on Android File Host as a mirror, and wipe and flash everything from there. Like I said, that's only if you tried flashing from the latest TWRP v2.8.7.0 (available in these sections) for the VK810 and still had this problem. If you do switch to CWM, you can switch back after flashing the ROM for backups and such.
Good luck!
Success!
Success! :laugh: I am now running ViKtory rom! It's debloated and rooted and sweet! Thank you so much for your help. I believe this is the 2nd time you've saved my tablet!
One last question: Do I need to flash aboot to access recovery with your rom?
Here's all the steps I took on my path to success, just in case anybody finds it helpful.
===============================================================================
To return to stock, unbrick, or prepare to root.
===============================================================================
1: Open LG Flash Tool 2014
2: Use the following settings:
- Select Type: CDMA
- PhoneMode: DIAG
- Reset time: 33000
- Select KDZ file: Use newest to go back to stock unrooted
Use 11A if planning to root/twrp
- Upgrade with CSMG Client: Normal Flash will not wipe, SCE Flash will wipe
3: LG Flash Tool will open LG Mobile Update tool. If an error window pops up
saying "Cannot connect to server..." Ignore it. DO NOT CLICK OK! It will run
it's course and the tablet will reboot.
4: Done with that.
===============================================================================
To root
===============================================================================
Use Stump Root app. (Bruteforce)
===============================================================================
To install TWRP custom recovery
===============================================================================
1: Connect tablet in debugging mode.
2: Navigate to where loki_flash and twrp.lok is.
3: Open cmd from this location.
4: Run the following commands:
4a: adb push loki_flash /data/local/tmp/loki_flash
4b: adb push twrp.lok /data/local/tmp/twrp.lok
4c: adb shell
4d: su
4e: cd /data/local/tmp/
4f: chmod 777 loki_flash
4g: ./loki_flash recovery /data/local/tmp/twrp.lok
4h: exit
4i: exit
4j: adb reboot recovery
The tablet should now boot to TWRP
===============================================================================
To install ViKtory rom
===============================================================================
1: Boot to TWRP recovery v2.8.7.0
2: wipe system, data, cache, dalvik and internal storage DO NOT REBOOT
3: Go to Mount > enable MTP
4: Copy ViKtory rom and SuperSU zip files to tablet (and debloat scripts if
desired.)
5: Install zip files (may have to switch between IMG and ZIP to see them.)
6: Reboot.
ALL DONE!

Great! You're welcome, I like hearing about successful device adventures.
Yes, the exact directions what I have at the bottom of the first post. I'm unfortunately not knowledgeable enough to solve the boot into TWRP problem with the Lollipop bootloader / getting Lollipop to boot without he Lollipop bootloader on the VK810, although @xdabbeb gave me some ideas to try if I ever find the time.
LG Support tool get stuck at 60% installing new firmware/KDZ files to reset LG ms323 phone to factory settings.
What is the solution to this problem?
Hello I hope someone could help me.
I have an lg g3 D855 international version, with kit kat 4.4.2 and its the 10e version.
I've root my device in order to install new custom rooms. At first I wanted to go to android marshmallow official and wanted to do the flashing with lg flash tool, but in every computer I have, it does not working, its either stuck in 2% and then it fails, or 4% and then it fails, and I tried to erase an install the new drivers and the old ones in the computer... But I couldn't get it to work. So I decided to root my device, and install twrp recovery, so I did. First I try to install the latest version of twrp, this I did it directly from the phone via TWRP manager. It was supose to work... But when I finish installing and went to recovery.. It went to a black screen saying "[700] fastboot mode started" or sometimes "[760] fastboot mode started" to my surprise the phone is not softbrick. I removed the battery and then reboot the phone and it works... But everytime I go to recovery or tried to install a new bump recovery... Because i thought that was the problem is still the same. I tried to install a new recovery with ADB but when I put the file path in order to install it... It said it couldn't find the recovery img in the path... But it was there... And I tried, but couldn't get it to work. I have some experience with custom roms on samsung galaxy s3, but change my phone, and this lg g3 is really making me crazy.
Thank you very much in advanced.
Any updates? Im having the same exact problem (d851)
In which computer you are trying the process. Which windows is installed on computer that you are using for installing stock rom.
Which guide you are following to install stock rom. Have you unlocked your device for bump, if not follow the guide.
http://forum.xda-developers.com/lg-g3/orig-development/bump-unlock-lg-g3-twrp-d852-d852g-f400-t2900614
I am dead sure that your board is not d855.open your phone to confirm this.that is the reason your twrp is not compatible with your board.

Same problem for me.
I was using TWRP for weekly update of LineageOS 16.1 on D855 with no problem.
Before updating to Lineage17, I updated it to twrp-3.4.0-0-d855.img (https://eu.dl.twrp.me/d855/) using TWRP App.
Then I tried to boot in Recovery mode and I got black screen with the message:
[700] fastboot mode started
I tried older version with no success installing them with ADB or TWRP App.

Hello,
So, i was trying to install root on my LG G4, version H815 (no letters/numbers after)
I did successfully unlocked my bootloader (info message on left top corner when booting) - official LG unlock
Booted into TWRP - twrp-3.0.2-0-h815 from ADB
- Installed UPDATE-SuperSU-v2.46.zip (which is located on internal storage) from TWRP - https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip
- Clear cache (dalvik)
- Reboot
Phone started booting, and got stuck on the LG logo
I did try to get it recognized in download mode and I did try to enter recovery mode (but I didn't install TWRP, only boot into it.. so I was left with the "default" one)
My phone doesn't enter recovery mode (I get the dead android bot with red exclamation mark)
At this step, somehow ADB recognized my phone, and I tried installing SuperSU again, and once again same thing happened.. I got stuck on LG logo
After this until now, I'm not able to:
- see my phone in ADB
- download mode with LGFlashTool2014.exe to flash .kdz "Europe OPEN H81510D.kdz" - getting error on LG Mobile Support Tool - "Upgrade stopped due to an error'"
I was following this: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Currently I'm trying all the steps from here http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
I just wanted to ask, is there a better way? Is there a working way?
Thanks, any help appreciated!
What firmware were you on? LP or MM. If the firmware was MM then you should have used SU 2.52 otherwise you end up as you are now.

You should also have flashed any custom kernel first that will allow you to not boot but install TWRP and then easily root. To flash firmware for G4 we use LG UP, nor Flashtool2014 and Mobile Support Tool ( G4 is not even compatible with it! It says on their website that you have to download LG Bridge)
I fixed it by using LG Bridge
- Update error recovery option
It installed android 6.0 on it
Then I used BETA-SuperSU-v2.67-20160121175247.zip for root, and everything seems to be fine
Thanks for your help!
Hello everyone.
I am newbie here.
I own t-mobiles lg g3 and updraded to marshmallow as the ota updates became available. But due to certain reasons, i wanted to install custom rom. The primary hurdle was rooting the device. Through trial and error method i have now successfully installed the fulmics 5.3.
I want to share my experience in this regard.
Device : d851 ( t-mobile lg g3)
Software veesion : 6.0 official marshmallow.
Root :-
Through mobile's browser, google for kingsroot. Download and install. ( donot reboot as this is temporary root, one the cell is rebooted the device will regain its previous status).
download twrp.image for d851 and save in sd card.
Now download flashify from play store and open the app. It will give three options. Select the first option ( browse image file or some thing like this) and select the twrp file you have recently downloaded. The flash will b completed in few seconds.
Congratulations, you have installed twrp.
Download a copy of custom rom ( fulmics 5.1 recommended) and save in sd card.
Now reboot the device in recovery mood ( either by turning off the cell, and then pressing simultaneously volume down+ power button, as the lg logo appears, release the power key and again press it. You will see two options, select the YES twice.
In recovery mode, first select wipe, advance wipe, system and then slide to wipe. Once done, go back and install the custom rom. After the successful installation, dont select the reboot option. Instead go back and again select wipe, factory reset.
congratulations, rom has been installed.
But you will observe sim card is not read by device. This is because cell was not properly rooted. To tackle this problem, download the modem file for D851 and flash it.
Enjoy the new custom rom.
Thanx.
Sorry for poor presentation and, offcourse, my weak english.
Man! Thanks for this! I have been looking everywhere for a way to do this and you are all the help I needed! Thank you!!!

Sure could have saved a lot of time if I had found this first.
I did install TWRP using a kingroot temporary root, got lost in a boot loop installing Fulmics 5.1 lost my data connection and imei information and finally downgraded back to stock Marshmallow feeling blessed to have restored my data connection. Had just finished transferring the flashable modem zip over to the SD card with an idea that I would try to move the mountain once more when I stumbled across your post which is priceless with the wealth of solutions to the problems I've had to overcome with the install. Flashify was the route to go. Lost TWRP on last flash and was just about to go through my torturous route of installing Fulmics 5.1 from scratch (root/adb/twrp/rom/bootable modem/etc.. Instead in the time it took to sign up so I could thank you for the easiest directions to this LG G3 D851 nightmare, I'm up an running on Fulmics 5.1 with full data connection. Your method eliminated a lot of the problems introduced by going the other route. Also you highlighted the main things. The factory reset is crucial and with the tricky temp root of Kingroot, it's easy to get stuck. Same with SuperSU flash/WRP and the modem flash. This should be a sticky on most sites related to LG G3 because it is the simplest way to go.
Jesus christ! Is this the only way to root my t-mobile D851? Seems like this is a dangerous way to live! Lol. But Really...
thank you, i will try it could you please give me fulmatic 5.3 room link for (d851)
Thanks for sharing
I am a newbie and do not have much experience with rooting or installing flash. But I followed your instruction and installed the fulmics.. I am struggling to flash the modem file. Can you please provide step by step instruction to do that pls. I am using flashify app
But you will observe sim card is not read by device. This is because cell was not properly rooted. To tackle this problem, download the modem file for D851 and flash it.
I am no expert either, but I believe you need to flash it in TWRP. Boot in to TWRP recovery and flash the modem zip. TWRP recovery-> Install-> modem zip-> reboot when finished
KingoRoot just seems shady to me, I wouldn't touch it personally. Here's what I did (just yesterday), from Stock MM Unrooted:
Downgrade back to original factory stock image: http://www.androidexplained.com/downgrade-lg-g3/
Root (used PurpleDrake "manual" method as auto script didn't work): http://lgg3root.com/lg-g3-root/how-to-root-lg-g3/
Once rooted, install SuperSU & TWRP Manager from Play Store
From TWRP Manager install latest version of TWRP
Boot into TRWP and do a factory reset/clear cache; flash ROM (Blisspop for me, but same general steps should apply for any ROM) and Gapps from TWRP; factory reset/clear cache again for good measure
Edit: Data works with 20B modem.
How to prevent apps from being unistalled in stock rom? In other roms u can lock the package installer .
In stock simply u just hold and drag the app to unistall button . installation of an app can be locked but unistallation cant be locked . is there anyone to solve the issue . sorry for bad english
i flashed another kernel and it is not that good... is it possible to find the kernel and just flash it ? without reflashing the rom?
KingRoot is not working for me, says Root Failed, somebody know why? What can i do?

You should be able to get the stock kernel back by "dirty flashing":
-boot into recovery (twrp)
-flash ROM *without* wiping anything.
Not to lecture, but this can all be prevented by following this simply advice:
-ALWAYS take a backup before flashing anything/customizing this or that.
-ALWAYS double and triple check that the ROM/Kernel/Whatever you're flashing is for your SPECIFIC MODEL and CARRIER.
Happy modding
