I rooted my phone, then installed CM12 Lollipop ROM. Now my phone is no longer rooted. I thought that after installing a ROM the phone remained rooted. Now I can't root my phone, the adb command doen't work to root it again, also tried the TowelRoot method, but it doesn't work. Any suggestions? I want to root it so I can reboot into recovery and install other ROMS or backup my current ROM (using TWR manager or Clockwork MOD ROM manager) and run other tools.
If you installed CM12, then you have root and recovery. I'm not sure what you did wrong or what you've missed, but it's all there. Did you go in Developer Settings and make sure that root access is enabled. Also, you need to have SuperSU installed as well. Good luck.

Adb reboot recovery doesn't require root. So that's an option. Also cm supports advanced reboot into recovery when you enable it in developer options.
Off topic. How well does cm12 run on this device? Thinking about putting it on my d850.
Never mind. Don't worry about my question. I'll look through the thread and see what I can find about what's broken.

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.
Just flashed the factory Rom and got everything set up. I flashed TWRP then tried to flash the latest SuperSu to get root and it installed it but when I went to open it it would say that I don't have any binaries installed and I can't uninstall SuperSU either. I tried to install CWM Recovery and refresh it through there but I still have the same issues... :/ What am I doing wrong or how can I get my phone rooted properly? Thanks for any help!

You need to flash a kernel that is permissive and then flash SuperSU there are a few in the forums if you search you shall find them
Instead of a permissive kernel, simply use Chainfire's AutoRoot, which will flash a more secure kernel and SuperSU automatically. You don't even need TWRP for this. http://download.chainfire.eu/363/CF-Root/CF-Auto-Root/CF-Auto-Root-hammerhead-hammerhead-nexus5.zip
Go to http://autoroot.chainfire.eu/ to get AutoRoot for other devices.

So I flash this in ADB? Is the secure kernel the same as stock? and if I were to flash a customer kernel like FK would I lose root? Sorry for all the questions just trying to clarify some stuff so I'm not completely ignorant to what I'm doing lol
There's a batch file that does it. You run it in the bootloader, not ADB.
FK has a Lollipop compatible kernel, but try and root stock first. Then flash FK's Lollipop version (it's different) and run CF AutoRoot again. Just to be sure things are working. Personally, I'm going to use stock for a while, understand the performance and then try FK or EX or whatever, so I'll be able to tell the difference.
Phone was acting sluggish, used moto device manager from my PC & did a software repair on 24.3.7 running 4.4.4. Now I have no su binary installed. Still showing rooted qe 1/1 but super su will not take. My boot loader is unlocked, any help would be appreciated. I need my hotspot back since we have no home internet. Thanks
Droid Max (hopefully still rooted ) and unlocked running latest stock 24.3.7,

Your saying when you download supersu from playstore it wont load when asking for root?
I would load a custom recovery (TWRP) through ADB. That should get you root if you are BL unlocked. Reboot into recovery and TWRP should ask you if want root.
I may do that, still debating holding off until root for 4.4.4 comes hopefully with lollipop we can get root again. I don't need the ROMs I just liked the hotspot option. On the flip side ROMs u can customize pretty much anything. Busybox installer says I'm rooted but I have no write privileges so it won't install binaries.

If you are unlocked, you can simply install a custom recovery (TWRP) as mentioned and you'll get root back. I've never run a custom ROM on my Maxx, but am unlocked, fully updated on 4.4.4, rooted and running hotspot through Xposed.

So I have the wife's new d850, which we will be suing over straight talk.
- not able to get the OTA updates
- at KK and she wants to be on LP
So far, I've done:
- rooted with towelroot
- loaded TWRP from the playstore
- loaded Superuser from the playstore
- loaded Busybox from the playstore
- loaded Flashify from the playstore
I have tried to flash these 2 roms will no luck.
[ROM][Stock][Rooted] D850 20f Stock ROM Debloated
http://forum.xda-developers.com/att-lg-g3/development/rom-20f-stock-rom-debloated-t3059610
Stock LG D850 20F Lollipop 5.0.1
http://forum.xda-developers.com/att-lg-g3/development/rom-lg-d850-20f-lollipop-5-0-1-extras-t3052041
So using Flashify or TWRP I have been unable to see the ROMs to flash and I have been getting the unable to mount external sd card.
I've gone through the forum several times trying to figure out what I am doing incorrectly and I haven't been able to figure it out.
All I wanted to do was debloat the phone and get it on LP.
thanks for any assistance.
Are you on 10d? Are you sure that root was successful? Does SU install properly? If so then are you able to grant Flashify SU permission? If so then you want TWRP from this thread, http://forum.xda-developers.com/att...recovery-twrp-touch-recovery-2-8-3-0-t2981108, by 777Jon. Follow his instructions for flashing TWRP through Flashify.
If root was not successful try Stumproot also here on XDA.
Are you on 10d? Yes
Are you sure that root was successful? It says I am rooted, so I assume yes.
Does SU install properly? Yes
If so then are you able to grant Flashify SU permission? Yes.
That TWRP did it. The flash worked and its on LP. The only thing is that the debloat didn't seem to work and I still have the carrier apps, which is easy to correct.
Thanks for the help. It's much appreciated.
Glad to help. Titanium backup will get rid of most of those carrier apps. Some you can simply freeze... Good luck.
This post is to get TWRP running properly on a G2 that has updated to 5.0
There is an apk called autorec.apk that is supposed to install TWRP, and it does, but when you reboot, it gives you a security error and shuts the phone down. Basically soft bricks it. This method is what i used to install twrp and allow flashing of custom ROMs.
First, downgrading to 4.4.2 is not only fairly easy, it is also necessary to get TWRP working properly.
Download and install the LG flashing tool here
then do the same with the LG driver found here
Then youre going to need 2 files for the flashing tool
1: LG Flashing dll
2: the 4.4.2 image that the flashing tool installs here
instructions for using the flashing tool are found here
Make sure to follow all of the instructions including changing the port # for the device to 41
After flashing back to 4.4.2, using towleroot to root takes mere seconds to complete
after that, download TWRP and place the file somewhere easily located on your phone.
Install Flashify, and use it to flash the TWRP 2.8.6.0 D800 image file for your custom recovery.
VERY IMPORTANT!! Reboot your phone to recovery and once in recovery, be sure to reboot recovery from within TWRP before rebooting system.
After that is done, you are ready to flash custom ROMs.
This is the procedure I used and it worked like a charm. There might be other methods that work, but this one positively worked for me on the D800 i dealt with.
I know this set of instructions isnt as pretty as other tutorials, but it works. Let me know if you have any issues with the links or process.
The way I have done it on my 5.0 d800 G2, first root with One Click root from Windows, then install SuperSU from play store, autorec, then install TWRP. No problems whatsoever.
Im glad that your method worked for you! The G2 i was working on belonged to a friend of mine and it kept bootlooping using your method. So, i guess for those who encounter the same issue that I did, they can use the method listed above
