***Its my first Thread here, i m just a member, NO developer***

***forgive me for my bad english***

***Links etc are NOT my work, i just complain several Threads in 1. from stock --> rooted device!***

***So THX to TWRP, Wolfgart, Poster in the links etc. MOST THX for Wolfgart, by them all a beer :D! http://xdaforums.com/member.php?u=608699***

*** If u dont know what u do and dont know the meaning of the words in the Header... DONT TRY this!!!***

*** and also for all other: do it on ur own risk, it worked for me, maybe not on u...***

Like the Header says: JUST H815 (European Version LG G4), Tested on my own device, works!

1. i tell u my little Problem

2. i link much with little explain HOWTO "unlock bootloader"--> "install TWRP"--> "root with SUperSU"

3. all is tested on Windows 8, so on all WIN it will work! and i cant help with other OS!!!

INFO and my little Problem at the start:

First i tried on my Laptop from work and that was the ONLY Problem i got to get my LG G4 H815 to root.

--> be SURE u real local admin on your computer! on my Laptop me local admin, but there also some Grouprights, domaincontroler and some more **** to get this save :p

*** just Info what problem i got, explain HOWTO later... ***

- i connected my phone to the Laptop with the right driver and SDK-tool.

- I started CMD in the folder where the "fastboot.exe is located (like: C:/Android/sdk/platform-tools/*fastboot.exe*)

- i tried to see my device, wrote--> "adb devices" *yeah i see it* :)

- i tried "adb reboot bootloader" to see if it boots into it *yeah me in the bootloader locked*

- i tried "fastboot reboot" NOTHING happens! i tried the commands u see in the bootloader, NOTHING happens! i tried Hard reset (10sec Powerbutton... 20 sec Powerbutton) Nothing happens! OMG... but THX LG for changing Battery, so got out the Battery and started the phone again. All was fine. I tried this more than 5 times, every the same result.

So i changed my computer, to my real privat PC. there i know 100% me local Admin with no restrictions, no special Grouperights, domaincontroler, Firewall i can handle etc.

And that helped me! :fingers-crossed: so keep in mind, u got 100% adminrights on ur computer!

in the next steps there are links with explanations, REALLY go STEP by STEP how it is written there, IMPORTANT

HOWTO

1. install LG Driver install the right LG Driver Version3.14.1 http://www.theandroidsoul.com/download-lg-g4-driver-for-windows-and-mac-mtp-adb-download-mode-77723/

2. download sdk-tool download sdk-tool https://developer.android.com/sdk/index.html

- u need the "fastboot.exe, AdbWinUsbApi.dll and AdbWinApi.dll" which are on normal install located maybe: C:\Program Files (x86)\Android\android-sdk\platform-tools

3. Test adb and fastboot!!! TEST if u can use adb and fastboot on ur device!

--> open CMD (shift+rightclick = "commandline open here") in the folder where the "fastboot.exe" is located maybe: C:\Program Files (x86)\Android\android-sdk\platform-tools

--> type in commandline "adb devices" (all without the "", also the following steps) --> u will see ur H815

C:\Program Files (x86)\Android\android-sdk\platform-tools>adb devices

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

List of devices attached

LGH815cc833317 device

--> if u see it like that, type in CMD "fastboot reboot"

If u can boot into bootloader AND reboot ur phone with the command, u can go to 4. if NOT, DONT go on, try to look for some fixes or solutions in the Forum!

*dont close CMD, we need later and u are on the right commandline where the fastboot.exe is located (C:\Program Files (x86)\Android\android-sdk\platform-tools)

4. unlock the bootloader

- go to the LG Developer Page and register (if u are not registerd) as "LG Developer Member" http://developer.lge.com/main/RegisterCheck.dev

- open the HOWTO unlock from the LG Page http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS

--> the first steps are Important: OEM unlock! and USB Debugging on ur device!

- on the botton of the Page u confirm go to the next Page

(open it with rightclick --> "open in a new window", that u can switch between the "howto" and the "starting to unlock)

where u start to unlock. U need the IMEI and the Device-ID. U can click on "?" to see how to get the IMEI and how to get the Device-ID

U will recive a Mail withe unlock.bin

- i pushed this unlock.bin into the folder were my "fastboot.exe is located" (on me C:\Program Files (x86)\Android\android-sdk\platform-tools)

- follow the steps with "adb reboot bootloader" and in bootloader "fastboot flash unlock unlock.bin" (if ur unlock.bin is located in the same folder, like me (C:\Program Files (x86)\Android\android-sdk\platform-tools)

Ur bootloader is now unlocked :)

5. install TWRP recovery

- download modified TWRP with simlink from Wolfgart: http://techerrata.com/dees_troy/p1.img

- follow the steps how to install, but remember, we use the TWRP from Wolfgart "p1.img" http://www.theandroidsoul.com/how-to-install-lg-g4-twrp-recovery-easily-79553/

- i did my TWRP (p1.img) again into the folder where the fastboot.exe AND the unlock.bin is located (C:\Program Files (x86)\Android\android-sdk\platform-tools), so u need to type in the Step 9. on the Page "fastboot boot p1.img" NOT "fastboot boot g4-twrp.img" like it is called there, because we have the "p1.img" and the downloaded on page is called "g4-twrp.img"

- just follow ALL the steps and u got TWRP installed :)

--> important in the steps on the link: u need TWRP (p1.img) on LGG4 and PC!

--> IMPORTANT Step 10.-15. in the link! 1. u JUST boot into recovery and in the (just booted) recovery u install the recovery!

- if u do the steps right (10.-15.), u can boot into recovery with the *knowing* "Power and Volume Down" combination or the fastboot command "fastboot reboot recovery" (do u want a factory reset "yes"... u really want? "yes" --> recovery :)

- if DONT do this steps right (10.-15.) and may JUST boot the TWRP (p1.img) and try the *knowing* "Power and Volume Down" combination u REALLY RESET ur device and may got bootloops

6. install SuperSU to get root

- download SuperSu and get it on ur phone https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

- follow the steps http://www.theandroidsoul.com/here-is-lg-g4-root-79569/

and all is fine, u got unlocked Bootloader, TWRP and u are rooted :)

Now the most important thing i have learned over the years: MAKE a NANDROID/Backup in recovery AND TEST IT, if u can recover!!!

- connected phone on PC --> CMD started from the folder where the *fastboot.exe* is located TYPE: "fastboot reboot recovery" to get into recovery.

than u can try more things u want, BUT dont Test XPOSED arm64 for now, IT DONT WORK, u get bootloops.

Other and me tested, i was happy because i got a NANDROID... others not ...

so do a BACKUP and TEST it

Remember thats NOT MY WORK, i just explained and linked it in 1 Thread HOWTO.

So all THX goes to the other

If me forgot something or something is wrong, let me know, that i can change it!
