and it showed me " UNROOTED " and i try These Apps " Root Checker " AND " Simple Root Checker "

i put 2 photos of those appsm, see them .

Please help me with this :o

thanks :good:
[G2 Q&A, Help & Troubleshooting] d00lz:
You are most likely rooted. Do you have SuperSU installed? It is recommended you install that as it allows for advanced management of Superuser access rights.

There is one definite way to find out if you have root.

Download Terminal Emulator.

Open it and type "su". You will get a SuperSU prompt to grant it root access (see below).

After granting it root access, you will now be shown as the root user (see below).

.

If you get a "permission denied" message, you do not have root.

I Typed "su" and this page was opened .

You're right :) my device has been rooted. thanks man :good:

i want to know how can i unroot my g2 (d802) completely ? do you know any simple way to do that ?
[G2 Q&A, Help & Troubleshooting] d00lz:
There are 2 ways to essentially remove root.

Method 1:

1. Open SuperSU

2. Click on the Settings tab on the top right corner, and then click Full Unroot.

3. Choose "Continue" and wait for the unrooting operation to complete.

4. Reboot your device.

5. Uninstall SuperSU.

6. Confirm having no root access by using an app like Root Checker.

Method 2:

1. Return to Stock firmware. I prefer this method as it will 100% remove any traces of root.

2. Confirm having no root access by using an app like Root Checker.

Correct me if I'm wrong but you said a few posts back you flashed your kdz, then rooted with IORoot, and now you've taken the OTA. Perhaps try flashing the kdz again, not rooting, and then take the OTA update.

As i said in the previous post I'm not quite sure why you would still have ROOTED after flashing a stock kdz. Perhaps someone else may be able to give you a more in depth answer.

I've got my LG G2 32GB today. It has D80220H firmware and came from Germany (but my language, polish - is in there). I managed to perform a root modification, with help of Stump Root. It took about 5 minutes to go. But now, I want to install Cyanogenmod 11 (and in future - 12), but:

- I don't know how to check if I have locked bootloader?

- how to install TWRP on D80220H firmware (I read that it was corrected by LG to avoid loki method)

- I'm strongly afraid of modyfing aboot and abootb files (I used to have D620r - LG G2 mini and I bricked one with such modification).

- in case I have unlocked bootloader (phones from Germany probably don't have it locked, they have?) - how to install TWRP anyway...

Please lead me to proper threads, or let me know method how to achieve my goal :) tnx in advance!
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
The boatloader on these phones is locked down. Not unlock able. You can flash a recovery with Loki on your firmware but you must modify your aboot img for that. There is a way to do it without touching your boatloader if your interested in hearing about that though.
[G2 Q&A, Help & Troubleshooting] twinsen.net:
Thank you for reply. So, please let me know how to omit bootloader lock and flash TWRP recovery, which allow me to flash CM11 (and in future CM12) into my new phone. I'm somehow lost in many threads here at xda. As CM11 is compatible with LG G2, so must be a way to flash it over locked bootloader?

LG G2 and StumpROOT

Hey guys. Not really new here and understand the basics of rooting, before anyone asks, just in case. Anyway, I have a LG G2 VS980 running 4.4.2 VS98027B and I decided to root it. I used the Stump Root method and Bruteforced the root. Upon reboot (I had a moment of worry here) the phone rebooted as normal, but then immediately shut off and rebooted again without any input. As of now, everything seems to be going smooth, other than the startup lag I always get, and I am typing from it right now. I just wanted to know, is it okay to go ahead and work on my LG G2 now, or should I be worried that something went wrong? Last time I rooted I used towel root, but now that doesn't work, and I never had problems with it. Right now, StumpRoot successfully rooted my G2 and Root Checker belives so. Thanks for any support guys.

Lollipop update?

Hello guys, i wasn't on the news for LG G2 last month. I last knew that there is stock update to Android 5 for the Korean version. But is there already update for our LG's (d802). I know about CM12, but i mean stock. I'm sorry if it is silly question, but i wasn't able to find any information in the forum or in the news. Thanks guys.
[G2 Q&A, Help & Troubleshooting] twinsen.net:
I bought it brand new, from the market, but not from big one, rather it was stall in big market (in the corridor) - but it is gsm seller and reseller network in Poland. My G2 was produced for Germany as I checked my IMEI on some page taken from here. It had all foils on it, front screen sticker and all accesories. IMEI starts with: 3541. Ok, I'll go through thread you linked. Then, only bootloader is from JB, rom could be KK of course (like CM11 is)?
[G2 Q&A, Help & Troubleshooting] d00lz:
Yes that's correct, using the AutoRec uses the Loki exploit and downgrades your bootloader to Jellybean, however you will still be running KK firmware as it's included with CM11.

---------- Post added at 11:46 AM ---------- Previous post was at 11:41 AM ----------

Ignore the dialog window, or simply press okay and let your phone do it's thing. Happened to me once and I looked down at my phone and to my surprise, it was upgrading the firmware regardless!

If this doesn't fix your problem, try running the application as an administrator and double check your /etc/hosts file to make sure the intended server can be contacted.
[G2 Q&A, Help & Troubleshooting] twinsen.net:
But, I think I have to downgrade original stock ROM from D80220H to something lower, because as I read, loki exploit does not work with this version. What version do you recommend for my phone? (D802, 32GB)?

Do IR blaster and FM radio work in CM11? FM radio probably would work with Spirit FM, but IR blaster?
[G2 Q&A, Help & Troubleshooting] d00lz:
AutoRec should work with D80220H, where did you read that it wasn't compatible? #1502.

As for IR and FM Radio functionality on CM11, I can't comment on that as I have never used CM11. However, you can find a list of known bugs for CM11(d802) on the Cyanogenmod wiki, http://wiki.cyanogenmod.org/w/Known_Issues_page_for_d802.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
For FM you have to switch Kernel, AFAIK. Best if you search in the official CM Threads. The IR Blaster works just fine, using either a G2 or G3 Port of the QRemote App. Keep in mind that the G2 one doesn't support ART.

[G2 Q&A, Help & Troubleshooting] d00lz:
Terminal access can be found in the PlayStore. Search "Terminal Emulator" and download it.

The reason your build.prop is not saving is because it's a system file and you don't seem to have read-write access in /system. This is also why you could not delete lteconfigs.apk.

Run the following code in terminal,

mount -o rw,remount /system

After successfully mounting /system as read-write, edit your build prop file and see if it stays on reboot.

If unsuccessful, try my method 2.

Remember to revert the changes made earlier and remount /system as read-only when finished,

mount -o ro,remount /system

If I understand it correctly, when performing factory reset under stock ROM, you basically erase everything you've put in the phone. However, I just noticed recently that factory reset does not seem to remove directories such as DCIM, TWRP and TitaniumBack (as well as the files underneath) under a custom ROM. At least that's what I saw in CM12 ROMs. Of course this is convenient when we flash different ROMs, but why is the difference in factory reset between stock and custom ROMs? Thanks!
[G2 Q&A, Help & Troubleshooting] UserofAndroid1813:
Factory Reset

This is entirely based on how the ROM handles Factory Resets. On a Custom ROM, it will save those files because it is attempting to keep a backup of your stuff. The stock ROM was coded to overwrite everything, no matter what the file is.

Helllo guys,

I'm a newbie and today i accidentally deleted my CAMERA folder on my phone assuming that im deleting only a single photo :( Now in order to rectify this, ive learnt that i have to root my phone in order to try solutions.

My phone info :

4.4.2.

Kernel : 3.4.0

Version : D802220c-TUR-XX

I'm using stock rom and everything.

I'm planing to install "Towelroot" first then from the google play store i will install "SuperSU" and after i gain Root access i will install "DiskDigger undelete" from google play store and try to recover my lost photos.

I will need my Warranty later (because of a yellow g spot on my screen ) so I'm assuming after rooting with Towelroot, i can still go back to being unrooted right ?

What do you guys think about this ? Can you please help a newbie out ?

Thanks
[G2 Q&A, Help & Troubleshooting] d00lz:
You have many options to root, IORoot, StumpRoot, TowelRoot. Whichever one you choose just make sure you follow their respective guides thoroughly and pay close attention to specific model compatibility.

You can easily go back to stock unrooted leaving no traces of root by following the Return to Stock Guide. I recommend unrooting this way since you are planning to send your phone back under warranty.

On some rare occasions, after returning to stock unrooted, your download mode will still show ROOTED on the screen in plain text. It's worth checking download mode after you return to stock to see if you are affected by this problem. However, if you are don't worry. Theres a solution to easily change it back to saying UNROOTED which can be found here.

Good luck with getting your photos back.

Well why not? Root, custom recovery (autorec), and flash kernel. All guides linked in the second post of this thread. Just never flash any zip that isn't made for your variant (VS980).

Everything that can happen is that your phone reboots. Why don't you undervolt btw?

Reflash the gapps. That should solve your problems. Btw: At the moment you have to reflash the gapps after every update. Sadly it is like this since there is no backing up system-apps function yet.

Seems like the TWRP Terminal Command isn't as functional in recovery as I thought it was. Correct me if I'm wrong here, but wasn't this based on a 'what if' situtation, incase TWRP's MOUNT option didn't mount your OTG Cable? Have you tried just using the MOUNT > OTG Cable option included with TWRP? It really should work flawlessly.

Download your 2GB .kdz file. Store it on your computer. It's an invested and justified download since you aren't 'wasting' that bandwidth. You're essentially using it on the heart of your phone. Once you have your .kdz file you can use a Win32 application like the KDZ and TOT extractor to extract the .dz file from your .kdz file. After that you can go even further to extract your .dz file to be given a list of all your devices stock files, including recovery.
