[Q] Can't root LG G3 F400L

I've rooted quite a few G3 without any hiccups but recently I got this F400L with firmware 4.4.2 and version 10u. I've tried towel root, stump root and purple but every time I get this error "Device not supported" tried add commands as well but same result. Tried hard reset but can't get it to root somehow. Any suggestions will be helpful. Thankyou

TWN/TAIWAN V20İ LGD855 - Root Methods Don't WORK :(

Hi everyone,
I have D855 INT, version TWN/TAIWAN. v20i officially released in a few days. I flashed v20i kdz file with flash tool, rom is perfect. When I try to root with One Click Root tool or DP Root, DP Tools and SEND_COMMAND script etc. all methods do not works at this time. Is there a way to root v20i? I use both v20h and v20p, I had not any root problems. How you root when you get v20i?
Thanks.

I am not getting error. SU Binary does not installed, so I could not get the root access. I think LG blocked that.

This woreked for me:

Try several times if you don't get at first

Downgrade first maybe?
I had to downgrade to my carrier's stock ROM for Kitkat and then I was able to root with the methods listed above. Then I could flash a custom recovery with Flashify and flash a nice ROM like Cyanogenmod or something. Proccess took a while as I soft bricked my phone originally haha

Thx a lot, it worked for me (the other solutions didn't work).
It failed the 1st time. After to clean it (clean recent apps), it succeed the 2nd time :good:
Then, you can do this to have SuperSU and to remove Kingroot: http://zidroid.com/how-to-get-ride-and-replace-kinguser-with-supersu-app/
(I confirm that it's ok on my LG G3 32g TWN-v20i)

Help.
Any other effective method to root LG G3 32GB D855 v20i-TWN? I Actually tried every method I could find From one click root to manual and king root. Nothing works with my phone. :crying:

How many times did you try Kingroot? It took me about 5 times to get it to work. You must also be connected to the internet. I have the exact same model and it did work after a few tries.

I tried alot of times more that 10 ans different versions of it the latest one and previous kingroot versions. What happens is that when I try to root my phone it gets stuck on 16-18% then the kingroot app closes when I try to open it again it says it failed.

Need help rooting my lg g3 d855

Hi. So im having a hard time rooting my g3. Im currently running lolipop 5.0.1 and have been trying to root via qbking77 method with zero luck.
The gui version gives me a "could not open the port" error. I tried the script version, but it was missing the root bat file for some reason and it also failed. I even tried to do it manually and it would not even recognize my device. Please help if you know a work around or a better method.

rooting the G3

Been searching high and low to make this work. I have d855 running marshmallow but am in able to root it. Tried several one click ones that has failed (kingroot just ends saying root request and a number just under 30000). Kingoroot doesn't do anything. Iroot I've managed to get the cmd thing to work but not the rooting. Have left the phone with kingroot running to see if this request/adapting thing actually lowers.
Any ideas where I go wrong?

The marshmallow version on the phone may be too new and you may have to downgrade to an older version to root. Which version is currently installed?

6.0 I think the kingoroot page said it could handle it (marshmallow in general)

There are various version of MM so it's important to know the exact version of the phone. Apparently, kingroot can root some early releases of MM based on some threads I saw.

It's an d855 or is there another piece of info you mean?

Look under settings and software information. Marshmallow builds begin with 30x where x is a letter.

I have same problem
Kingroot is not work
V30e-AME-XX

If you can't find a root app that works, a ROM downgrade will be required.

Don't you need to be rooted to do that?

No, root is not needed to downgrade but you'll need to find the correct lollipop ROMs to flash.
https://forum.xda-developers.com/showpost.php?p=64624324&postcount=2

Tried the first option on that thread but I only get update stopped due to an error.
Have tried to install twrp but having problems with adb. I thought the adb kit would be enough to make that work. Any idea what else to try?

Go in general thread and search for root marshmallow 30b that guide helped me root my g3 with kingroot. Tell if i helped

I found (I think) the thread you referred to but it seems to require that you have twrp installed. From reading the twrp website i got the impression you need to be rooted to install twrp? Have tried to load the image file from the SD card but can't find it when I reboot it. Not sure where I go wrong but I cannot get it to work.

You need to downgrade with LGflash tool to v30b and use latest kingroot 5.0. Then kingroot will root your phone and autorec file will flash twrp 2.8.0

Tried to do that (see post above) and it didn't work. No idea why.

Is this the thread we are talking about?
https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268

Yes and the one at the bottom of page one which tells you how to downgrade to lollipop. The downgrade does not work for me. It only tells me an error occured. The thread you refer to, I think you said you need to downgrade first and the root which I can't do as the downgrade failed.

Try flashing the file v30b from this video and then see if rooting with kingroot works.

Thanks. I'll try that later today.

Account closed so cannot see the file.

Pls pls help me?? I bricked my LG g3 d855

pls can someone help me. I would really appreciate and honor you guys. let me tell you already what s my problem
I bricked my LG g3 d855, I bought it maybe 2 or 3 days
from now. and on my previous phone I rooted them
all without any issue and install custom ROM and
recovery which called (twrp or Cwm)
so this LG g3 with running 6.0mm frmwre I tried to root
using kingroot but it was failed bcoz of updated security patch and kigroot does not support that kid of version. so I searched for another method of rooting.
then I found some forum that has the rooting process for LG g3 which I followed his procedure.
then I downloaded the same os marshmallow but lower release date maybe. kingroot does not support marshmallow with v30c up so I downgrade my LG G3 to lower marshmallow version. which is v30b.zdk files.
so the downgrading process was successfully done and flashed through lg flash tools via donwload mode.
then here it comes . so after I downgradey new lg g3
kingroot finally worked, BUT after o rooted my phone. there's still steps to follow according on the forum.
so installed kingroot.
I had to download the following files like he said.
so I downloaded the LG root file.
note: I have root access via king root
then I put lg root files on my phone Internal storage.
then run the autorecovery file which is the twrp. via file explorer
then it booted and bang it says you can now boot into twrp received
but it boot and bang turn off and dead. no power no download mode no recovery no sign of light
I tried to detect it using qhsub Qualcomm or adb fastboot but I think I miss something. computer detects my device with it power off but driver s not installed successfully. pls pls help.

It happened to me 2 days ago.
Google for "Fix hardbrick LG G3". you're gonna find multiple guides showing that you have to create a short between 2 points on the MB.
It worked pretty well for me, my G3 is now working properly.
