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] 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.

[Q] Lg G2 LS980

Hi guys i have an LG Sprint LS980 and i factory reseted it a few days ago. After reset i was unable to use my GSM sim on it. Browsed through the forums and found a permanent unlock and now i can use my GSM sim again, however, i have a few problems discussed below:
1. The sim unlock method did not work with ZVE, ZVC and ZVA as i was unable to drag and drop " Property folder" from Carrier to/carrier/ in my device using Total commander from my PC, hence i had to flash to ZV8 then rooted with iroot and sim started working but now after accepting OTA the phone has updated to ZVA and sim still works. After this my g2 started to download ZVC OTA and i installed it too but after reboot my G2 still shows version as 4.2.2 (jelly bean) and as ZVA instead of ZVC. Software update also shows that phone is up to date. SO I AM STUCK AT JELLY BEAN ZVA.
2. In all the versions that i have flashed (ZVE, ZVC, ZVA and ZV8) i have been unable to go into recovery mode via TWRP app or quick boot. Clicking on flash in TWRP App does nothing, while in quick boot my g2 reboots but after lg logo boots into homescreen instead of recovery mode. So i am unable to flash cloudy G2 v 2.2 rom.
SUMMARY
- G2 won't update to Kit kat and stuck on ZVA jelly bean even though ZVC installed via OTA.
- G2 won't go into recovery mode no matter what i tried so can't install cloudy G2 v 2.2 rom.
- If i flash to ZVE then my GSM sim will not work and i will be unable to apply permanent sim unlock as it will not let me drag and drop " Property folder" via Total Commander.
So i am unable to update to latest version both via OTA as well as via flashing (as my sim will not work on it) and also unable to install custom cloudy G2 v 2.2 rom.
Please help out sirs. These couple of days were like hell to me :crying:

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers from the owners/experts.
Stand by
Good luck

So your download mode is broken or not? It sounds like you were only rooted. I don't know much on the Sim issue. But you could tot to zv8, and then maybe hit cm12 after running auto-rec.

No download mode is working fine. But recovery mode is not working whether via quick boot or TWRP so i am unable to install cloudy g2 rom. And if i flash to ZVE my sim does not work. Stuck on jelly bean
And what do you mean by "cm12 after running auto-rec"?
That is the problem man, recovery mode not working no matter what i try

So, you can run lg flash tool, and take it back to zva or zvc and root. Use auto-rec to get TWRP. Install cloudy g2. Putting your change in. Or use the flash tool to go to zv8, grab official cm12. Root, use auto-rec to get TWRP, update TWRP. Flash cm12 (lollipop) with gapps. And change what you need to get your Sim working.

Will using Auto-rec be safe. Googled the app and many users reported white lines or bricked phones?

Bricked only if they used wrong one. If you are actually on ls980, use ls980.
Don't use t mobile version because you are using their service on an ls980 phone with Sim unlocked.
White lines is due to kernel. There was the two different screens used. That was identified but auto-rec kernel was never adjusted. When you flash new ROM, kernel will be replaced and that will be fixed.

[Q] D851, BUMP, TWRP, and Stock Lollipop Questions

Hello, I have the T-Mobile LG G3 D851 and I've been trying to find the best configuration. I came from a Nexus 5 that I would either run stock 5.x or CM 12. The CM12 for LG G3 is great but it doesn't have a good camera.
Anyway, I've come to enjoy the stock firmware that LG puts on these phones. So here's what I want to accomplish, however I feel I cannot find enough information to do it confidently.
I would like the have TWRP installed with Stock Lollipop 20b, with root.
Can I just bump a TWRP image and use flashify or something to flash it? or dd?
I installed the 20b KDZ and rooted using the one click method, and that's how my phone sits currently.
From what I understand I need to downgrade to do something with the boot.img so that I can manually flash 20b with a bumped recovery? I'm not sure what bump really is entirely. Do I need to bump all TWRP images that I install? If bump is required for the G3, do they not come pre bumped?
I know that my first go around, I had flashed TWRP with flashify, then installed CM12 without any issues. So I'm wondering if this is just for stock ROMs or did they do something to the boot in 20b that would stop anything from installing without being bump'd?
I also noticed most of the bump'd threads don't list the d851 so I'm wondering if T-Mobile doesn't require this?
Keep in mind I've searched and read extensively and cannot come up with a clear picture of what to do. I've become too used to Nexus devices it seems :-\

D851 has unlocked bootloader. You don't need bump. Just flash twrp via trwo manager or get the inage and use flashify.
