Hi every one,
I currently am using an LG G2 from tmobile (801 model). My device says its rooted but it doesnt have root access because I forgot to flash supersu binaries before i flashed the 4.4.2 version of the software. But now my custom recovery doesnt exist anymore.
I've tried using LG flash tools to flash back to 4.2. stock settings to start over but I am unable to do so for some reason. LG Flash tools isnt able to recognize my G2 in download mode. My computer is able to recognize my G2 when it is turned on though.
So is there anyway to flash a custom recovery without root access?
Or is there anyway to flash supersu binaries without a custom recovery using ADB?
I've tried trouble shooting with multiple threads and multiple downgrade methods but none of them are giving me any luck. I really want to flash a custom rom on my LG g2 and have the benefits of root access.
Any help would be greatly appreciated.

All you need to do is install the towelroot.apk to give instant temporary root. Then install SuperSU from the dev thread here on xda or from the play store. After installing SuperSU go to its settings and select install as a system app and reboot when finished. It might take 2 attempts before it successful (it always takes me 2 tries). Then uninstall towelroot as it's no longer required since you've gained permanent root. Now install the autorec.apk and you'll install TWRP recovery. Now that you have root and recovery and have control of your device you can customise to taste. In my case I always install busybox and a terminal emulator so I can further fine tune my system.
I hope this helps

still got issues :/

However even when i go into supersu, it keeps saying my binaries are not up to date. So i cant install anything and I cant do anything to install a custom recovery without root access.

So you have installed Towelroot, achieved root then having issues installing the SuperSU.apk this is indeed an issue. Towelroot should allow for it to be installed. When you install Towelroot do you get the warnings from the installer and Lookout that the package contains an exploit? Do you interrupt or stop it from fully installing when you see the warnings? The only thing I can think of is you are doing something wrong when installing towelroot which is prohibiting it from doing its job in gaining root.
I can't find a guide for dummies for it, nor any compatible automatized program or a rom created for it...

Been away for a while now so can't vouch if there is a custom ROM available at this moment for your specific K2 variant. However, rooting is very possible. Simply unlocking your bootloader and booting up TWRP recovery is enough to do the job since TWRP will root the device for you. TWRP will or should detect if the device is rooted or not. If it is not then when you select to reboot your system it should ask if you would like to install SuperSU or in lamen terms, to root your device. Obviously you will say yes at this point. When the device reboots then go to the play store to update SuperSU. Once it is updated open the SuperSU app so it can update the su binary. It will ask to update the su binary either normally (by writing to your system with write permissions) or via twrp\cwm. To select the normal option you must either be S-Off or have a custom kernel specific to your K2 variant which has write protection removed. Otherwise, you must select the twrp\cwm method where it will reboot back to the custom recovery and make the change from there. Once the su binary is successfully updated then you are now properly rooted. Do not EVER flash a custom ROM unless the ROM Developer states that it is compatible for your device.
Hi there.
My phone was rooted (used it for xposed installer, titanium backup and tasker). But as I wanted to upgrade to lolipop I've installed SuperSu program from playstore and under settings I chose unroot permanently. It did unroot as titanium backup is reporting my phone isn't rooted. I downloaded OTA file and it asked for upgrade. It rebooted but after a few seconds it reprted error and my phone just rebooted.
So how do I properly unroot or do I have to do something else in order to upgrade from kitkat to lolipop?
I don't use custom recovery.
EDIT: Hm It looks like root checker says root access is not properly installed. So I don't know if it's properly unrooted. Should I follow this guide instead: http://forum.xda-developers.com/showthread.php?t=2542219
Please help.

I've just used this method to restore firmware: http://forum.xda-developers.com/showthread.php?t=2542219 so now I'm unrooted 4.4.4 210.12.40.falcon_umts.Retal.en.GB but when I go under System updates I get: Your device's software is up to date.
Damn. So much fuzz and not OTA won't give me any updates. Any suggestions?
Hello all, I am facing the "super su binary need to be updated" wherever I try to update it it simply does not. I have the pro version also but nothing happens. The next time phone is restarted it askes me the same. Anyway to update or install another updated version? I also un installed the current version and installed the last one from the Market but nothing.
Thank you in advance!
if you have bootloader unlocked, you can flash a custom recovery, then manually flash the latest supersu.
I have root access but not the bootloader unlocked

When I've got this message, I answer "Continue", then "Normal" and Super SU will update...
Possible Solution
How did you root? If you rooted using KingUser, it's interfering with SuperSU.
I do "normal" but it is not possible than it ask me for reboot. And it rebootes but nothing changes.
I have rooted looking at the post "how rooted without bootloader unlock"
I cant flash the update cos I don't have a costum recovery.

Thanks, I've updated the main post, waiting to test another method (https://www.xda-developers.com/root/) and to get a dedicated P2 section on XDA...

Hi kiselina777, I too am searching for a root method that doesn't require unlocking the bootloader (most because of the 14 day wait), have you had any luck in finding one?
Hello Colloseo,
do you have any news regarding the systemless rooting?
Thanks!
Any progress at all regarding systemless rooting?
Does anyone tried these methods already? Any update on that?
when comes method 3?
and is this really also possible with the P2?
At this time, the only available methods are described here:
Lenovo P2
I had a problem
I've tried the first way:
unlock the bootlader (and wait 14 days)
get adb
flash TWRP
put the SuperSU .zip file, found here supersu.com/download, in the normal memory (i don't have a sdcard)
open the recovery, that now is TWRP recovery, search the supersu .zip file that i previously put in my phone and click install
reboot the phone
and NOTHING, absolutely NOTHING, I've done it so many times, reflashing the recovery, installing SuperSU from the play store before installing from the phone, but whenever i enter the SuperSU app it says "no root found".
Even if TWRP recovery said "installed succesfully" my phone still doesn't have the root privileges, did I miss any passage?
EDIT
I've tried with me.phh.superuser.apk, found in the xda developer instead of the SuperSU official site, and using the superuser256.zip found in the same site (forum.xda-developers.com/showpost.php?p=73667960&postcount=5).
Work perfectly
Thanks medwatt !!!!!!!!!!!
