So, long story short, I followed this tutorial: www . htcmania. com/showthread.php?t=1024045 (remove the spaces in w.h and .com) and it didn't go very well.
I flashed TWRP and SuperSU as told, using both download links (TWRP 2.8.7 & SuperSU 2.46), and my phone got stuck in a bootloop at LG bootloader unlocked logo. I recovered my phone by using LG Bridge and after that, when i tried to enter TWRP using the phone keys, it resulted in a factory data reset (no TWRP after recovery, didn't know that). I then followed the exact same steps but using what I thought was the lastest SuperSU archive (SR5-SuperSU-v2.82), flashed the archive and when finished, TWRP asked me to flash it again (so I did), then rebooted, passed LG bootloader unlocked logo, got into LG animation and... Bootloop again, so I recovered again with LG Bridge but I din't attempted to enter TWRP because this time i knew it wouldn't work and I ended it there, reinstalling all apps and configuring my phone as I had it before my unsuccessfull attempt. I continued using my phone as usual but sometimes, when I enter Pokemon Go, it says that it couldn't log in and that my phone's OS is not supported. As I said, the app does this sometimes whenever it wants, so I researched a bit and turns out it doesn't work with rooted android devices (I didn't know that). I knew my root attempt failed so I downloaded and app called Root Checker and checked: Root status-Not rooted; SafetyNet Status-Failed. I don't know what should I do know, last time I rooted my phone was a Sony Xperia XL and it wasn't so tricky.
I asked for advice in the forum and got no answer, so here I am, hoping for a solution. What I want is to have a permanent custom recovery, a rooted device and to have SafetyNet status passed. Any ideas, hints or whatever? Please, help

I have a Verizon LG G3 and wanted to root to change the ROM. I used kingroot to root and then was able to add superuser, root checkers showed I had root and superuser access. I read online a few people were able to use flashify to put Twrp on their device. I selected the VS985 and after it was done it would not boot into recovery. The phone loads and runs fine but now ot shows the phone does not have root, superuser says it needs update and fails, and I cannot even do a factory reset.
How do I fix the recovery so I can either finish the root and recovery installation, or just go back to stock?
Thanks!
Phone is on Marshmallow. Guides I found to fix say you need to be on lollipop. Phone boots right now, so I do not want to risk trying too much since it boots now.
Fixed it using lg flashtool but with this dll file http://forum.xda-developers.com/show...4&postcount=84
Today, I did everything which was in this article:
http://htc-one.wonderhowto.com/how-to/unlock-bootloader-root-your-htc-one-m8-0154444/
Possibly I forgot about turning on "usb debugging" after unlocking bootloader.
I used the newest TWRP and SuperSU.
After all I restarted phone and now it stucks on the HTC logo.
I tried to perform factory reset (I have access to bootloader) but it doesn't help.
What should I do now?
solved, I flashed CM 13 and everything is ok.

I know you got the phone running another way, but what version numbers TWRP and SuperSU specifically? Folks often claim they used the "latest", but when prompted for actual version numbers, we often found they are not even close to using the "latest".
Hey all
First of all, this is the first time that I'm trying to root a phone, and it didn't go well.
I have an LG G4 with Marshmallow installed on it. Found out that I needed to do, and it didn't look too hard to me, so I tried it.
I managed to unlock my phone's bootloader, and get TWRP onto it. (Which apparently was needed in order to get root access on 6.0)
I flashed the system image. Got a confirmation that everything went well, so I restarted (via the TWRP menu).
And now, my phone is stuck in the booting process. (displays the logo + "Bootloader unlocked" in the left upper corner.)
I tried a factory reset via the system recovery, didn't change anything.
Since I voided my warranty, is there a way to fix this myself? (I haven't found anything that helps me so far)

why did you flash system image.? rootedsystem.img are used on locked bootloader..
if you unlocked bootloader and installed twrp. all you had to do was flash superus in zip format or a custom kernel.
does download mode works? turn off phone pres vol up connect usb cable.??
if so then flash stock firmware. with LG UP. you need to flash the same android version you are on.. theres antiroll back security on some phone and if you use lower android it hard bricks phne . so if you download KDZ make sure its the same you have..
What model phone (H815, H811, H812, etc) do you have and what did you flash?
Can you boot to the bootloader?
I cant get to download mode/bootloader
It's a H815
Hello
I tried rooting my LG H815 and it didn't go so well.
I managed to successfully unlock the bootloader following the steps on the LG developer website.
I downloaded SuperSu (UPDATE-SuperSU-v2.46.zip) and placed it in the internal storage of the phone.
Afterwards in order to root the device, I booted into TWRP with "fastboot boot twrp-3.0.2-1-h815.img".
In TWRP I flashed SuperSu. After it finished flashing I rebooted the device. After it attempted to start up again, it froze at the LG logo. I waited around 10 minutes and figured it's not successfully boot.
I removed the battery and tried to fire it up again, but it didn't get past the Logo screen again.
I managed to send "adb reboot recovery" to it, but all I get is an image of a little dead android. I guess this is because I only booted TWRP and did not flash it.
When I get it in fastboot mode, "fastboot boot twrp-3.0.2-1-h815.img" does work anymore now. I just says < waiting for any device >.
I managed to get into default recovery with power up + vol down where it prompted me to do a reset by responding Yes twice, but after it rebooted, it still got stuck on Lg logo.
If you cannot get to the recovery then follow these steps:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
This shouldn't delete your data (no guarantees) but you will have to grant app permissions again and reapply any changes to system files e.g. root, viper4android, xposed ect.
If you have problems try this method instead:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
If successful and you're brave enough to try again. Then make sure you actually flash TWRP. I think you are right in that you only booted TWRP .
You can follow my TWRP/root guide here: https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
Good luck
Thanks a lot for answering.
LG Bridge wasn't detecting my device. I don't remember if I was in download mode when I tried this, though. I might've not been.
I didn't know how to fix it and asked a friend for help. He managed to flash the h815 stock firmware through some Taiwanese/Korean flash tool (Edit: It was LGUP and he flash a kdz file with the stock firmware).
I followed a similar guide to yours when I flashed SuperSU from TWRP, except I didn't install twrp permanently after booting it from the .img file. I thought it was not possible to install twrp if the device is not rooted first.
I still kinda want to root the device since I voided my warranty by unlocking the bootloader, but I'm afraid I'll break it again if I use the same method.
Edit: Managed to successfully flash twrp. Booted into recovery again after rebooting system. I am now creating and saving a full backup with TWRP. Will try flashing SU again afterwards.
Edit2: I flashed SU after properly installing TWRP and it worked like a charm.
Hello members of XDA,
The issue I'm having is pretty rare and found few or non threads about it, so I will try to be the most precise possible.
Yesterday I decided to change the ROM of my LG G4 H815, I was previously on LineageOS, since LineageOS on H815 wasn't developped anymore. So I asked myself why not trying Android Oreo with CypherOS. Before any changes I was with the latest version of LineageOS for H815 and I had TWRP with the version 3.0.2.1. Bootloader was obviously unlocked.
So I starded to download all the required material to switch to CypherOS 5.3.1, while the download I've made a backup of my actual lineageOS installation on my internal storage. Once every thing was downloaded I tried to install CypherOS I had an error 7 in TWRP install box, so I was pretty worried, scouted XDA threads about the error but i was redirected to the solution where you modify the update binary with txt but still didnt worked. I've found a thread talking about updating firmware of the H815 ( https://forum.xda-developers.com/g4/development/v5-8-5-n7-1-2-resurrection-remix-t3704450) While panicking I've done a wipe of everything (dalvik, data,cache and system) .I applied thge firmware update but I also re-read the thread of CypherOS and figured that I needed a newer version of TWRP, installed it so. THen magically CypherOS installed without any issue.
After installing the Gapps (Arm64 8.1 Nano) I rebooted and the first weird thing appears, after seeing the LG screen while the boot I have another screen telling me that the bootloader has been locked and that i should visit g.co/ABH for more information, then CypherOS initialise, CypherOS worked like a charm. So I wanted to go to my TWRP and make a backup in case. I launched ADB and use the command adb reboot recovery, the phone restarted and had the following events : LG logo, warning message about the bootloader, LG logo again and then a black screen. However I was in recovery mode since adb found me with the command fastboot devices. I had no TWRP logo or anything linked to it. Few minutes later, I had the basic recovery mode where you move yourself with the volume buttons and select with power where the functions are pretty limited.
Then I rebooted the phone with adb (fastboot reboot), CypherOS still working perfectly. Thaught that it was the bootloader which back to scratch when he was blocked, I figured out that he was still unlocked, I used the command "fastboot getvar unlocked" through ADB. THen I thaught i had to install back TWRP, tried through the fastboot mode but I had an error
Code:
FAILED (remote: unkown command)
since i tried everything i could even in the basic recovery mode, the only working command in the recovery is "fastboot flash recovery twrp.img" but still does nothing.
I mean it's not that terrible since I can use my phone and i'm about to change phone in 2 months for a Oneplus but i would really like to be able to install magisk on the phone to grant root access and be able to use TWRP on it like I used to. By the way the backup of lineageOS has been deleted while performing unecessary wipes.

It's clearly written on the official website and in the official TWRP support thread for the g4 what you have to do when on Nougat bootloader and want to flash TWRP... and keeping it.

Yet, this still doesnt help me to solve my issue. Do you think there is a way to fix it or no ? If not, I'll just deal with it for the few months lasting.

Okay if it doesn't work for you you must do something wrong. It works 100%. If you really want help you should explain in detail exactly which steps you took as otherwise it's all just guessing what you're doing.

Indeed, I didn't followed the procedure exactly, didn't do the step after flashing TWRP (removing battery and boot manually to recovery). Well thank you, was my bad on that.
Should I do a clean new install of cypheros or should I keep it like that, what would be your advice ? Knowing that at the moment CypherOS works like a charm. I also plan to install Magisk on it to root it.
