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 didnīt work, tablet said thereīs no OTA for rooted devices.

I unrooted using SuperSU, but the situation is still the same.

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.

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/show....php?t=2707363
