OTA Update for rooted g pad

Hi!
Has anyone installed the update OTA on a rooted g pad?
Is it safe to do it or it's not possible?
How can I install the update if I am rooted and keep my root?

I have seen people reporting problems in other threads here on XDA. Here in the US they haven't yet released the OTA update. If this is anything like my experience with my phone (a GS3). OTA update of a factory rom when rooted often does seem to cause problems. The only device I haven't had problems with taking an OTA when rooted were a Nexus device (Nexus 7) and something running CyanogenMod.

so I have to unroot it first, install update then root again?

I have a related question - how to unroot and install OTA??
I tried to install, but it didn´t work, tablet said there´s no OTA for rooted devices.
I unrooted using SuperSU, but the situation is still the same.

I used the LG Support Tool method which involves putting the tablet into download mode and doing the update recovery procedure in the LG Support Tool. This (after a long download process) should result in a tablet which is identical to what came in the box. (in the US the procedure currently installs 4.2.2). When it finished the download and install, it reboots the tablet, if you then are stuck in a boot loop, simply do the key combination for a factory reset and it then should boot.
The unroot procedure via SuperSU does seem to leave something behind that the OTA still detects...
If you need further details I have another post in one of these threads detailing exactly what I did...

That is what I plan on doing once the US version is released, however it is potentially a little more complicated since I have heard that LG has patched the LOKI vulnerability which means no custom roms or custom recovery until a new boot loader vulnerability is found, or until you revert to the original boot loader instead of the new one in the 4.4.2 release (if possible)...

Nah. You can bet that within 48 hours after the US version is released, there will be a flashable build available with root and recovery.

True, more than likely a flash-able version will exist once someone makes it.

It already has a work around for loki by reinstalling the old aboot

I upgraded Via OTA my rooted lgpad and when it rebooted... stuck in recovery.
So i had to flash with lg tool.
I did not lose any data but a bit of time.
My suggestion is to flash with lg tool and then root again.

I think the issue with this procedure is the recovery / bootloader, not the rooting itself. Still, you will most likely end with an unbootable OS. You are better off flashing via recovery a perfectly stock, pre-rooted image, like this http://forum.xda-developers.com/showthread.php?t=2707363

When you use the lg tool (pc software) did it automatically download the kitkat update?
Did you encounter any issue when you used lg tool?

So you did NOT unroot first?
Steps you did were: (with rooted only g pad)
Update via pc lg tool
Root using IOROOT25.zip method
This correct?

I had to click on "recover" Something sorry I have no my PC now.. I left it at work. But I think you'll find.
U got some option and considering lgpad did not boot after update.. I had only one.
It's the procedure that you got to follow after you set gpad in download mode.
No issue at all, just one thing: after rooting you will have to flash a custom recovery if you need, because flashing with lg, flash even lg stock recovery.

No I did not unroot.. But only because I did not think about it. And that's the reason why gpad was not able to boot to system and I had to flash it via lg software.
I set gpad in download mode,,then flash via lg software, root with ioroot and finally flashed with flashify custom recovery
Hope to have helped guys
Now I'll go to sleep!

I updated to version 4.4.2 Via OTA my rooted gpad and not had any problems
Steps:
1- factory reset
2- update via OTA
Attention: I think the rom has to be original (no eliminated sys apps with titanium or other) because it goes check the integrity of the rom (4.2.2)
------------------------------------------------------------ Edit --------------------------------------------------------------------------
3- Rooted with IOroot25

I've done an OTA update on my rooted G Pad, no issues either. I didn't do a factory reset, just did the update.

I updated my rooted v500 2 days ago using LGs PC software. The process took around 45 minutes and resulted in a successful KitKat update, however I no longer have root. I have a few strange issues with random unmounting of the SD card, which happened about 4 times while Play Music was copying 2gig of on device songs to it. I also seem to have lost quiet mode - maybe it's been moved out of the sound settings menu - would appreciate a comment if anyone knows where it is.

4.4. KitKat for Wifi Note 10.1 2014 P600 Q&A

Hi guys I have some questions about the new Firmware and KitKat in general and you may have answers I'll try to update first post with your answers!
-Will I loose root when I flash through Odin? --> Yes
-Is the new firmware rootable, or is there a way to keep root when I upgrade from rooted 4.3?
-->For upgrade yes: If you are rooted on 4.3 you can restore root by flashing a custom recovery and flash superSU manually.
-->chainfire autoroot works but you need to update the superSU app through play store after flashing.
-Will KitKat restrict access to my SD card? -->Yes but fixable through an app or editing a file (needs root), there is already a thread about that.
-Can I still use flash with KitKat? How?
-->Yes, there is a hacked version see 2nd post for link.
-How is the touchscreen driver? Is the stuttering fixed? Do touch and hold actions still drop after ~23sec?
-->Pretty much fixed. To about the same state as the improved Kernel we had a while ago.
-Are there any apps that are not working (root apps too)?
-Gesture Controls? --> works
-Xposed framework app settings? -->works
-Is Hancom Office included or does it still work? --> not included but does still work.
Thats about what I can think of a the moment.

Hi,
If you are already rooted then all you have to do is re install TWRP and then flash SU zip then you have root.
For flash player, download hacked version here, it works I tested it on new software :
http://forum.xda-developers.com/go...e-how-to-play-flash-video-android-4-t2548001
Also, xposed works. Tested it on new software

Chainfire's Auto Root does work, once you flash it thru odin and reboot, go to the Play store and update the app.
- Please update OP

Here's a question: I'm already rooted. Is flashing the stock KitKat image via Odin and rerooting the only way to upgrade?

If you are already rooted, I assume you have TWRP too. Just download this KitKat rom, full wipe and install.

Not for me I flashed a stock 4.4 kit kat on my tablet coming from root 4.3. I then flashed chainfire autoroot thru odin on the 4.4 and the superuser there only problem is it displays this ' There is no SU binary installed, and SuperSU cannot install this is a problem! I formatted my 4.3 before flashing it maybe thats why?

Not sure... I installed KK on the tablet via Odin, then rebooted and setup, then rebooted into download mode and flashed auto root thru Odin.
Upon reboot I got an error selecting SuperSU, but once I updated it thru the Play Store its been fine.
Using ES Explorer I removed the items I don't need and removed all of the Knox stuff.
There are a few of us this worked for so I don't know what went wrong for you.
If you don't succeed then try again, and again, and again....Good luck.

Thx for the response from what i can see you never fully wipe your data before installing 4.4 KK but i did so i believe i lost my root like that. So when i updated the supersu never carried over from 4.3

Both ways work equally well I was already rooted with 4.3 but either way has been confirmed working so it doesn't matter.

[Q] Upgrading to ZVC From ZVA Rooted

Hello,
I have a G2 Running Stock LS980ZVA Kernel Version 3.4.0. Now I rooted the stock ROM and now got a notification to update the ROM to ZVC.
Now my dilemma is do I "Restart and Install" this update or not. Will this brick my phone?
I have TWRP running as the custom recovery. What should I be doing? I tried to search for a similar thread but couldn't find one.
Any help will be appreciated.
Thank you!

You will brick. Either hold your finger on the notification and then click app data. Click on the show notification. No check mark. Notification will go away.
Regular reboot will not install the update.
If you unroot and put regular recovery back. Then you could.

okay, i did some research and found that it is safe to install OTAs but if youre rooted youll lose the root and unlock will still stay.
best imo, is you upgrade to 4.4.2 and root again with custom recovery and install a nice ROM.

How to update rooted G3 ?

do i have to unroot in order to update ?
what about updating my rooted g3 through lg pc suite? would that work?
would this method work : http://forum.xda-developers.com/lg-g3/general/guide-unroot-ota-using-lg-pc-suite-pc-t2802286
or is there any other way to do it without having to unroot?

What model of G3 do you have, and do you have TWRP installed?

d855 .. international 32 gb model
no TWRP.. only supersu which i just uninstalled

Same question.Do i need to unroot my device ?
And what about custom rom ? Cloudy cant be updated to Marshmallow right ?

that moment when even xda forum can't give u a clear answer !!

Sometimes using an OTA works. If not, flash KDZ to stock and update via PC Suite.

and i also found that it includes "fix upgrade errors".. which should get ur phone to perfect stock shape, without having to delete any files.
