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?

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.

[Q] Help with rooting phone

I have an LG G3 on T-Mobile, running android 4.4.2 and my software version is D85110r. I downloaded and installed Stump Root and when I load the app it says "Device is already Rooted". Then I remember I had previously rooted the phone last summer when I got it. But I'm having issues with several apps not working because of root permission. So then I download and install SuperSU and when I run it, it gives me the message, "There is no SU binary installed, and SuperSU cannot install it." It then says something about if you have android 4.3 you need to re-root your phone. How do I proceed? Do I need to un-root my phone and then re-root? Thanks for any help you can provide!

Anyone?

same here. I am not on 4.3 but still getting the same message. Fix?

You've flashed other root tools like Stump, etc.. right? It probably left some files behind after unrooting.. Factory reset and try that root tool again.. I've always used it and rooting was a breeze!:fingers-crossed::good: If you have updated to the latest firmware then maybe rooting isn't possible at the moment. Try downgrading to the previous version you had after you've factory resetted and used that root tool.. Good luck mate!

Unrooting help URGENT

Hi I want to unroot my G3 so I can get marshmallow without the fuss and stuff. The thing is flashing a stock lollipop will delete my data, which to me is very important. So I really have no idea of how to backup fully(except rom) other than taking a nandroid. Are there any other ways of unrooting which will undo my mods and stuff, keeping in mind I'm on a stock rom which is rooted, or any simple way to do a backup and restore from a rooted rom to a stock rom.

If I'm not wrong, when you flash the .KDZ it will un-root automatically your device. But just download Titanium Backup and backup all your apps, then install the bumped version of the MM (if you don't have TWRP installed, it is very easy to do it in LL).
I don't remember if Titanium can install all your apps back with theirs respectives datas without root, but you can root the device again if you install the .zip via the custom recovery. You can do it as well if you flash the KDZ, but as I have installed the bumped Marshmallow, I'll let someone else explain it to you.
Of course, if you still want to unroot, as you are in lollipop you probably used Kingroot or some app like that. Just open the app and try to find an option to unroot, most of them have it right when you open it.
Sorry for any typo or broken english, I'm in kind of a hurry

You can always root it again and restore your data using Titanium =P. The recovery is only needed to flash custom roms ou .zip files, like Viper4Android (although you can download the non-official one from Play Store), mods and etc.
I know there are some apps that don't need neither root nor custom recoverys, but I haven't used any of them, so I will let someone with more experience in that area explain it to you.
Just one more thing: I saw that there are ways of downgrading back to lollipop if you flash the official KDZ, but they're a little bit tricky, so I still recommend you to flash the .zip through TWRP (upgrade it to the 2.8.7.1 version if you haven't done it already). If you need more help, or if I wasn't clear enough, just mention or quote me and I'll se if I can help

There are 2 ways to get stock marshmallow running on d855s now:
1. Flash via TWRP 2.8.7.0 by following instructions from here.
2. Downloading KDZ file from here and flashing using LG Flash Tool 2014 or LGUP tool.
I would recommend that you use method 1 since you are rooted. You can use TiBackup to backup your apps+data and after flashing you will still have root and you can restore apps+data using TiBackup.
Also, method 1 is better than method 2 because if you use method 2, you will lock your bootloader and lose root. You MAY not be able to downgrade to Lollipop, and I don't think there's a reliable way to root stock marshmallow just yet.

I think you're misunderstanding me, I'd like to go back to an unrooted version of lollipop and eventually get the official marshmallow update. I don't want to get involved in flashing and stuff, it's just time consuming. So to sum it up - go to unrooted lollipop with all my data(no root mods) and wait for official update.

He wants to unroot the phone and keep all his data, so the only way he could flash the LL kdz and keep his apps would be rooting again and installing the backup using Titanium.
@OP, what root metod did you use? Helium propably will work, but I haven't used it yet. Try opening your SuperSU app and selecting the option to unroot in the settings. Most of 'em have it.

If you flash the KDZ using the CSE_Flash option, yes, it will unroot the phone. If you just dirty flash it, I don't know, maybe.
If you unroot by using the option in SuperSU, you'll be able to update using OTA, you will only have some issues (aka bootloops) if you have a custom recovery installed. If you have, don't EVER try to install ANY OTA.

By repairing, you mean just unroot and install the stock recovery back? I don't think so, the .KDZ file is a full OS. If you flash it you will have your stock recovery and will unroot, but your phone will be factory reseted

I don't think there is any option besides restoring the stock recovery. I've seen a way of doing in somewhere in a Brazilian forum, but you would have to have a backup of it, which I don't think you do. Anyway, your best chance is to use titanium backup to backup your data (and move your photos and videos to the sd card), restore the system by flashing it using the flash tool, root it again, restore everything using titanium, and unroot. But I highly recommend you to keep your device the way it is, and update just when there is a deodexed Rom or a custom stock Rom available. After you get used to having root and a custom recovery, there is no turning back.

Is there a root method for the Sprint LG G2 on Lollipop?

I bought a Sprint LG G2 and it's on the latest software (Lollipop). I tried using a few root methods, but every single one has failed or stopped in the middle. Have you guys tried anything that works?

I faced the same issue and after research on many forums I found that LG G2 received 3 updates in Lolipop ZVG >>> then ZVH >>> then ZVI if you want to root you have to go back to ZVH or before. I rooted my phone on ZVH with Iroot , it is the only method that worked for me,
I am not well experienced I am just telling you my experience with the G2 , I hope somone post a positif solution to this.

yes..for zvi rooting you have 2 methods..one is free another will cost you 3 bucks from the app store.
the free method:
1. Root using KingRoot.
2. Use AutoRec to install TWRP.
3. Download latest flashable zip version of SuperSU and copy it to device.
4. Go into KingRoot settings and choose "Full unroot" which will uninstall KingRoot and unroot.
5. Uninstall Purity app installed by KingRoot.
6. Reboot into TWRP Recovery and install SuperSU zip file from step 3.
7. Reboot and run SuperSU, it will say binary needs to be updated. Select Normal method. It should work.
8. Reboot when SuperSU has finished updating binary and profit.
the 3 dollar method ( one I choose) :
root via Kingroot ( downloaded from their website ) and then replace kingroot with SuperSU using SuperSU-ME ( 3 bucks ) from the app store.

yah just flashed my chosen rom.. got twrp on.. everythings good.. seems like so far $3 for me was 'unnecessary'

Lost ROOT, how do I go back to original partitions and reroot?

I originally rooted with Purple Drake.
I later lost root after flashing using an earlier TWRP that was incompatible with my ROM.
I regained root via Kingroot, although phone was still buggy at times, but definitely usable.
I recently updated my Magisk Manager. Or rather, I TRIED to update it.
I have lost apparently lost root and TWRP. Magisk Manager doesn't get past it's opening screen, no rooted apps have access (and I get a notice saying that Magisk Manager has closed), and I cannot reboot into recovery.
I'm running Android 6.0, D85130g.
Any help would be appreciated.
I was thinking about starting from scratch... restoring original partitions, rerooting, etc.

I'm thinking maybe you could use LGUP to start from scratch. I don't remember how easy/hard it is to root 30G. I remember downgrading via LGUP to 30D which was easier to root.

Okay, have some time and a computer I can use... so back to work on this project.
I have tried LGUP and UPPERCUT, neither will recognize my phone. Thoughts? Help?
UPDATE
Okay, I used the old 2014 LG Flashtool and flashed 30d kdz onto my phone successfully!
Any thoughts on the best way to root 30d?

On mine I went back to KitKat and then rooted with Purple Drake for the 851 G3. But I opted not to install TWRP because the version that comes with Purple Drake is older (2.7) and didn't work with what I wanted it for (plus I ended up bricking my phone.) So instead I just rooted with Purple Drake, then found and copied the newest version of TWRP to the phone (3.1) and then flashed that using the TWRP APP from the Play Store.
I hope that helps.
