- TowelRoot, but you have to be on NE2 firmware or older. If you have the NG2 firmware you need to downgrade to NE2.
- Not if you installed supersU as a system app, if not yes and if you have superSU Pro installed and enabled survival mode you keep root after an OTA
- Yes, unroot from within the superSU app, flash a stock firmware and data factory reset and after that your warranty is restored (at the moment anyway).

[Q] Is root persistent through OTA update?

I'm looking to root my phone but I don't want to flash any new bootloader or custom roms. I'm under the impression that I'll still be able to get OTA updates if I do this. My question is if I download and install an OTA update will I still have root on the phone or will it remove root? Thanks!

I was still able to receive and apply the OTA after rooting, but the OTA did cause me to lose root. But re-rooting was pretty painless.
Its sure than rooting phone you receive OTA and can install it?? If yes, I want to root my phone, only root, i dont want to change anything more for receiving OTAs.
How can I do? just only root, any link to the safest way?
Is the same way when I receive an OTA and i have to root again?
many thanks.
1. You can use an app called OTA Rootkeeper. Use it to hide root before you accept an OTA, then use it to restore root after.
2. Yes, you can use adb commands (possibly the Nexus 4 toolkit as well) to temporarily flash clockwork recovery and obtain root. You will need to unlock the bootloader though, and that will factory reset your device.

Good advice for OTA Rootkeeper! If I head down this path I'll make sure to use that. I'm still looking around for the best way to root without unlocking the bootloader or factory reseting.
Superuser contains a built in 'try and preserve root' function which worked well when I updated to 4.2.1

[Q] (I9506) Rooted 4.2.2 + OTA 4.3 update ready = ?

Hello,
I've got a new I9506 with 4.2.2 pre installed.
Prior to rooting it with this How-To (thanks for that) I downloaded the presented 4.3 OTA update.
Now my device is rooted and has the update ready.
It is bugging me all the time if i'd like to do the update.
Before I'd do that I would have four questions about what would happen:
1.) Will it even work?
2.) Will the device still be rooted?
3.) Will the KNOX bit stay untriggered?
4.) How do I get rid of the notification for the update, if I don't want to update?
Thanks in advance for any information.
1) You downloaded the update but unique way for install it is via STOCK RECOVERY coz u are rooted.
2) No. Your phone make factory reset when u install a update.
3) In theory yes. Its better unroot ur phone before apply the update avoid problems.
4) Deleting some apps of system/app with root explorer:
LocalFOTA.apk
SyncmIDM.apk
SyncmIDS.apk
Thanks mate,
bottomline I could unroot and update with stock recovery or flash the stock 4.3 directly.
But if I want to root 4.3 afterwards i would trigger the KNOX bit anyway, right?
Regarding the files: Will try to find them, thanks!

(INFO)After updating rooted .314 via OTA to .167 root stays(D6503, stock, locked BL)

My device is D6503. I had stock .314 rooted rom with locked bootloader. I updated via OTA to .167 and root remained except system partition write.
For this SuperSu was moved to system partition before update and also Survival mode was swithced on!
Another useful information is that if you do the SD Card fix on .314 it will remain after the update, so still all apps will be able to write on SD.
I was on Hungarian T-mobil .314 fw, unbranded phone.
UPDATE:
If you run the RIC killer from below, you will be able to mount system rw:
RIC killer
You lose no data during the update, even Xposed moduls works like before.
I thought this can be an useful information for everyone, if not moderators can delete the thread.
Which stock 314 firmware did you have before? Canada / USA stock 314 doesn't let you do ota, it forces you to use pcc for the update and you lose root.

Hungarian T-mobil, but the phone is unbranded. Also it is important to not have custom recovery installed, because then OTA won't install. You can only root if you want to be able to update via OTA in the future.

Hmm.. So flash a stock 314 fw (Hungarian tmobile confirmed) , root but don't install custom recovery, then do ota and it will preserve root? Can you install a custom recovery afterwards?

I'm not fully sure because you lose system partition write access after the OTA, so this have to be checked by someone. I don't install custom recovery because SD card fix and Xposed is all I need and I want to keep the possibility to use OTA updates in the future. I don't like when I have to reinstall everything and set my preferences again if I want to have a new fw with root, without exploit.
If someone checks this I will add the result to the first post.
Did anyone else duplicate this method?

I did another similar way: created my own personal rooted zip file and flashed. I loosed access to mount system..
Hope someone can fix it.

Yes someone in the thinktank thread did the same. So it seems like if you can do OTA and switch on Survival mode it works.
Yes you can, but you won't be able to mount r/w system untill devs find a kernel xploit to make it adbd insecure.
hi mates
more information would be of much more help, please :good:

[Q] Unroot Towelroot without Recovery

Hello all,
I have an LG G2 D80220c-222-88, with stock rom KitKat 4.4.2. Few months ago I rooted the device using towelroot, just to be able to install the xdabbeb's 3.1 camera. I did not installed any recovery.
I would like to know if there is a way to unroot my device, for warranty issue, and to be able to install further stock update. I already try to uninstall the towelroot apk but Root checker still find the device as rooted...
Thanks for any suggestion,
kindly,
Cisky
Does anybody know if 'Unrooter' tool, by bender_007, may works for my request? At least to upgrade to a new stock OTA release?
Search the threat return to stock for full unroot!

If you didnt installed Supersu after rooting with towelroot your phone is vulnerable..it grands root access to ANY app
Try installing Supersu(from Google Play), and then from SuperSU theres an option "full unroot"..and after full unroot use root checker to see if its still rooted
OR you can flash a stock firmware with lg flash tool, you will loose root and all things from your phone... You phone will be like new ( not sure if it will be like new new xD, i mean maybe in download mode it will still say"rooted" because it was rooted before...but even this thing can be faked if you need to return your phone for waranty...but how i said, im not sure that in download mode will say "rooted" after flashing the oficial firmware)

Thanks a lot for your answer, I unrooted the device using SuperSU (root checker confirm that i'm unroot), but still, i'm root on download mode, it means that I cannot update to any OTA stock update

Did you flash the firmware? You can flash the latest firmware instead of taking OTA
Or if you didnt flash the firmware, you are safe to update JUST if your ROM is clean...with clean i mean no mods installed like the camera mod that you installed...so its recommended to flash the firmware instead of taking ota
The latest firmware for d802 is v20h you can follow the instructions from here:http://forum.xda-developers.com/showthread.php?t=2432476

Install root, custom recovery, etc causes small modifications on system, partitions, etc, so LG software detect that and triggers the root flag.
Flash a jb kdz for your phone model, reboot, factory reset, update by ota to kk.
Pure untouched stock phone again!

S4 Question - Messed up root

I used towel root to root my S4, and I somehow allowed an auto update, which downloaded the updated, tried to install but failed. But I lost my root.
I am running 4.4.2 - Kitkat right?
So I don't have root, and I cannot update my phone - Is it possible for me to root it again? If so is there a link to instructions?
Thanks in advance, the DoridForums people sent me here -

I dunno what you are running.
1. You can take a look in your Settings - About device (Pic attached).
2. Try again Towel Root if you still running android 4.4.2 for root again your device.
3. Tell us how it works.
* You can download OTA udpates but you can't install them when you are rooted. Root your device modify system. It changes of OFFICIAL to CUSTOM. OTA detects it and give you a error when you try to install the update.
Ok attached is my about phone info -
I just tried towel root again, and it says this phone is not currently supported. So again, thought I would see what my easy options might be.
I can't post an image or links, Android version says 4.4.2 - If that's what you need? If not let me know which number you need
Use CF-Autoroot to root instead of Towelroot. While CF-Autoroot requires the Odin software to use, it's far more consistent in its results since it temporarily replaces the existing recovery with a recovery that will install SuperSU into the /system partition. Unlike Towelroot, CF-Autoroot is version agnostic, meaning it will work regardless of the version of Android installed.
There is an entire thread on CF-Autoroot. Hit the search bar at the top of the page and I'm sure you'll find it.
