One Click ROOT+TWRP Recovery for Lollipop Stock Firmware

-----------------------------------------------------------------------
I recommend you to use AutoRec For Lollipop 20H from @bender_007
@ingoljosh includes all version of autorec (D855, D852, D850, LS990 ...) in his post : Flash TWRP With AutoRec

First use OneClic Script ( by @avicohh ) to root your G3
Then install and use AutoRec to install the recovery custom

-----------------------------------------------------------------------
Only for D855

Only Lollipop (not KitKat)
(16GB/2GB and 32GB/3GB variants)
Use only this tuto in case of failure with the previous quoted method

Credit
- @6ril1 for all his advice and convinced me to publish this method here

@6ril1 thank to him for the bump of the 20P and 20G boot

20P and 20G --> If you are not root having applied this tool, copy UPDATE-SuperSU-v2.46.zip on your SDCARD , restart on recovery mode and flash UPDATE-SuperSU-v2.46.zip

For those who used the LGG3-D855-OneClickRootRecoveryV1.1.zip version (for 20H) on the firmware:
- 20P download this file :
Kernel fixed by @6ril1 (v20p) --> http://forum.xda-developers.com/show...postcount=1019

- 20G download this file : Kernel fixed by @6ril1 (v20G) --> http://forum.xda-developers.com/show...&postcount=220

And use Flashify or your custom recovery to install this boot
For more informations see here : http://forum.xda-developers.com/show...3&postcount=23
Thank's @black_horse_88

What does the automate script do ?

(For people can't use automate script we have to use manually ROOT+TWRP)

Make sure you are enable USB Debuging Mode . See this Method > Enable Debugging Mode


1. Pushing all stuff files

Run file

Quote:

Command Prompt.bat

It will be show command DOS windows
Quote:

C:\Users\M\Desktop\LGG3-D80230a-OneClickRootRecoveryV1.1>

Using command as below to push files to device
Quote:

adb.exe push busybox /data/local/tmp/ && adb.exe push lg_root.sh /data/local/tmp/ && adb.exe push UPDATE-SuperSU-v2.46.zip /data/local/tmp/
adb.exe push aboot.img /data/local/tmp/aboot.img
adb.exe push laf.img /data/local/tmp/laf.img
adb.exe push boot.img /data/local/tmp/boot.img
adb.exe push recovery.img /data/local/tmp/recovery.img



2. Reboot to Download mode

3. When enter to Download mode successfully.We need to send command to connect device with computer
Quote:

Send_Command.exe \\.\COM_PATH

COM_PATH . we can find with ports.bat command

Ex.
C:\Users\M\Desktop\LGG3-D855-OneClickRootRecoveryV1.1>ports.bat
C:\Users\M\Desktop\LGG3-D855-OneClickRootRecoveryV1.1>reg query HKLM\hardware\devicemap\SERIALCOMM
HKEY_LOCAL_MACHINE\hardware\devicemap\SERIALCOMM
\Device\LGANDNETMDM0 REG_SZ COM3
\Device\LGANDNETDIAG1 REG_SZ COM4


A command that send to device when connecting to computer with Download Mode is
Quote:

C:\Users\M\Desktop\LGG3-D855-OneClickRootRecoveryV1.1>Send_Command.exe \\.\COM4


4. When we see this prompt
Quote:

C:\Users\M\Desktop\LGG3-D855-OneClickRootRecoveryV1.1>Send_Command.exe \\.\COM4
Author : blog.lvu.kr
SPECIAL COMMAND : ENTER, LEAVE

#


Try to use this command to ROOT+TWRP
Quote:

# sh /data/local/tmp/lg_root.sh dummy 1 /data/local/tmp/UPDATE-SuperSU-v2.46.zip /data/local/tmp/busybox



5. When we see this message
Quote:

ui_print - Disabling OTA survival
ui_print - Removing old files
ui_print - Placing files
ui_print - Post-installation script
ui_print - Unmounting /system and /data
ui_print - Done !

Please press Ctrl+C, and then type N and ENTER to reboot.

#


Try to use LEAVE command to restart device.
Quote:

#LEAVE


6. Enjoy ROOT+TWRP

2- If you always have errors or blockings try this other manual method

1 - Apply this tuto : [GUIDE] New Root Method for LG Devices

2 - Then this one : http://forum.xda-developers.com/show...&postcount=104

3 - If your G3 don't boot on system but you can go on Recovery and Download Mode
Your boot is not correctly flash and we have to make it by line of commands

Huge Improvement!
HI @jac10000,

This is great! Way better than what I have posted.

I assume that this can be repackaged to cater to other LG G3 variants, by simply replacing aboot.img, laf.img, boot.img (users need to have this "bump'd" prior), and recovery.img (need to be "bump'd" prior as well) from those of their respective LG G3 variants, correct?

EDIT: I have promoted your approach in my how-to thread: http://forum.xda-developers.com/show...&postcount=455

Yes I think it's possible. I don't know the others models of G3 and their specific characteristics for installing custom recovery

HI @jac10000,

Great to hear.

Based on my experience in the Imageprep thread, installation of custom recovery is the same. I'll go ahead and try it out with my D858HK. Will let you know!

Does it make any difference if I have the LG G3 D855 16GB/2GB variant?

Can anyone report back?
