Verizon LG G Pad 8.3 system update

I rooted this tablet last week (just rooted, I left it stock) and this morning I notice there is a system update waiting to be installed. I am reading Lollipop is starting to roll out in Asia somewhere now but I am in the US lol. I thought it wasn't possible to get OTA updates once you root? If I allow this to update will I get unrooted, would it even work?
I foolishly allowed it to update after checking in Supersu to not allow the root to be lost and now I keep booting directly into TWRP lol. How do I wipe this tablet from TWRP so that it is fully stock again (NO ROOT)? I see a factory reset option in TWRP do I need to include all the partitions in the advanced wipe or is just the normal wipe method enough? Or will this not work at all? I already tried to restore the phone using TWRP to my backup and that didn't seem to work.

Simply rooting a device doesn't keep it from TRYing to update via OTA. Rooting can prevent an OTA from succeeding, plus can hard or soft brick if you try to take an OTA, although usually only if you've gone beyond just rooting by installing a custom recovery or changing the contents of any partition besides Data by, fire example, downgrading your bootloader (aboot.img) or modem, running a custom kernel, debloating system apps, etc.
There are at least three variants of the G Pad 8.3. I have the VK810.4G, which do you have?
I know on the VK810.4G, Verizon just released a very, very minor update from LG build #23A to 24A. Still KitKat.

There's the main problem, you had a custom recovery installed. OTAs are applied with the stock recovery, that's why it (probably soft) bricked it.

You might not be able to fix it from TWRP. You could try @autoprime 's fix recovery zip available the same page his flash2 scripts are. You'll have to Google:
autoprime flash2

.
Otherwise, you'll have to restore to 100% stock unrooted and start from scratch. Two methods.
One is using LG's official Mobile Tool, which will download the latest official ROM in KDZ format (takes 20+ minutes to download) and flash it with your tablet in Download mode (probably with the tablet off, hold both up and down volume buttons in and while holding them, turn the tablet on.
I've got to go do something so hopefully someone else will help further or I can get back to you later, dont know when though.
Good luck!

OK now that I am up and running fine the system update message keeps popping up. This time I KNOW not to try and upgrade while rooted. Is there any way I can stop the tablet from constantly giving me the upgrade message? Can I do anything from TWRP to stop this?

Don't install TWRP. I was rooted (w/ stock recovery) with 23A, and the OTA update worked fine (still rooted).

TWRP is already installed..
Can I uninstall TWRP, keep root , do the update and then reinstall TWRP? If so how? Is there any other way around this issue, any way of not having the tablet continue to ask me to upgrade? Thanks BTW...

Yes, you can do that, but I don't know the steps. Others here do.
Why do you want TWRP? I thought the usual reason was to install custom ROMs (in which case you won't receive any OTA updates). If you just want to root, it's an unnecessary complication (as you have discovered).

Thanks Dean, and yes I do agree with you about it being a complication. I was always under the assumption if I rooted a phone that I needed to also use some sort of recovery god forbid I had an issue with the phone not booting up or something so I could possibly fix the issue, make a backup/install a backup etc. Maybe I will ****can it if someone will tell me how to do so without losing my data or root.

I Have a Few Questions About Rooting My HTC One M9

Hey guys, I'm fairly new to the android scene when it comes to the rom and rooting side of things so I just have a few questions about Sunshine and the whole process in general. Sorry if this may have already been asked but after a quick search many of the answers to these questions seem to be outdated.
1. Do you need to be rooted in order to use Sunshine?
2. If I do, is there any method to root my phone? I can't seem to find any without paying some money.
The only reason why I would want to root my phone is so I can use Titanium root and back up my data.​
3. Do I have the order right?
Use Sunshine (gains S-off/unlocks bootloader)​Install a custom recovery (TWRP)​Super SU (Does this root my phone?)​Install Cyanogenmod​
4. If I have the order correct, at what point should I backup my data and when would my data get wiped?
5. And if I'm backing up my data should I back it up to my SD card and remove it, or do something else?
Once again, I'm sorry if most of the answers to these questions seem obvious but this is my first time tampering with my phone so I would appreciate any help!

Ok so a little update, I used sunshine, installed twrp, and tried to flash super su but I got stuck on a bootloop. Any help? I tried wiping the cache/dalvik.

The latest supersu zip will give you a bootloop. The previous version works fine. I don't have it anymore but you will need to download a rom and flash it.

Rooted 5.01 want to flash 6.01 - will i lose root?

I have 5.01 and I want to update to 6.01. I want to wipe it clean. Got factory image from Google site.
What's the difference between the OTA and factory downloads?
I can just flash the factory in TWRP right? Will I lose root, or will TWRP ask if I want to keep root?
I still have boot loader unlocked.I just can't remember for the life of me, haven't done flashing etc in a few years.
Thanks!

So...not a single person can tell me if I lose root, or if TWRP will re-root?
Please?

N7 is no longer supported by Google and there will be no more OTA.
You can't flash the entire factory image directly from TWRP (but it is doable).
When you flash the factory image, you will lose root, TWRP and all your data.
NRT can simplify flashing, rooting and restoring TWRP.

You have unlocked boot loader
Just fastboot flash all as yiu want clean install
After that fastboot flash twrp
After that flash superSU
Done.
No need for any toolkit's, try to stay away of them and do it manually.

I know it isn't supported anymore. They still have the image's though.
Im just confused... Long time ago when I was really into all this, I just went to Googles page, downloaded the .zip and flashed it in TWRP. Now, the Google page is different and there isn't just 1 anymore. Can I just open the factory image and unzip the update part and flash that in TWRP?
The OTA files are only for updating from version to version correct? Can't go from what I'm on, 5.01 to the current 6.1 right? That's what I talking about and why I'm so confused now
Googles page used to have the OTA zip to update from prior newest to newest(5.0 to 5.01 for example) but than they also had the full OTA so you could do a 4.0 to 5.1 or whatever. Why they change the site? Which one do I use now to go from my 5.01 to current 6.1?

That's the pronlem, normally yes I would do that no problem. I'm in the middle of upgrading my PC after had a surge or something and fried my ****.
That's why I want to do it via TWRP like I always did before. Every time TWRP asked if I wanted to retain root after updating also. So what in the world happened in the last year that It doesn't seem like I can now? Like I said above, I can't find a full update OTA on!y the incremental OTAs...

Ok yes that's possible
If you have twrp already
Check development forum and choose one of the ROM.
Download it to your tablet plus gapps
Wipe system, cache and data leaving internal storage.
Flash ROM reboot, come back to twrp and flash gapps. ( Can do ROM + Gapps in one go)
Download SuperSU and flash to get root.
You can't flash stock image / OTA via twrp.
While you're doing all this try the 7.0 ROM its good enough now.

Ahhh what happened??? Why can you not flash them with TWRP???
Thats what I used to do no problem. Not referring to custom roms either.
I am wanting stock rooted.
I used to download the update when one was released from Google's site, put the update.zip in main directory, go in recovery and flash update.zip. TWRP would ask me if I wanted to keep root, I say yes, reboot, update installs... than i'm on the new Android version still rooted.
How is that not possible now?

I am so annoyed... I never had to go through ADB or fastboot to update to latest. I did everything on my N7, it kept root for me and everything.
I feel so dumb right now its ridiculous lol
So than what way can I go about updating my N7 2013 Wifi, which I currently have 5.01. I am Rooted w/ unlocked bootloader.
What is the best way not using ADB, or a PC at all for that matter to update to the latest, 6.01. If possible, how can I keep root, if not i'm not worried about it, i'll just re-root myself.
I appreciate all the responses, sorry if i'm just being an idiot. I just know for a fact I never had to use ADB or my PC to update and keep root...

I'm not familiar with Stock OTA done with twrp (if that's even possible)
Already told you get a custom ROM, get the one mostly stock or if there's a stock ROM in zip format available.
In future you might need to update that bootloader of yours for newer ROMs
Sorry if this sounds harsh why are you so into keeping root as you can't do it again? It's simple as flashing SuperSU. Root method changed after 6 you cant have old methods with 6.
Best bet for you at the moment.

Accept OTA or Flash entire ROM?

Hello all-
I have looked everywhere for clarification on this to no avail. I am currently UN-rooted, Unlocked Bootloader & TWRP (OOS 4.0.3, 12/1/16 Android Security patch). Can I take the OTA for OOS 4.1.3 or will that make me lose TWRP? I know there are instances when you can take the OTA and where you have to flash the entire ROM but I can't locate the differences and which route I need to take? Please advise if you know this answer.
Thank you!

I'm not sure, but, you can just flash the ota in twrp and make sure to flash the twrp img after flashing the ota. And, always make a twrp backup

AFAIK you need stock recovery for OTA to work (not 100% sure).
If downloading whole 1.4GB ROM is not a big issue, it's safer to dirty flash the whole ROM. Otherwise you could flash back stock recovery, install small OTA, then flash TWRP again. A bit more work, but less downloading.

Let me make it clear, the full rom flash is a better option and you can do so from twrp. You would not loose twrp after the flash and need not flash the recovery again. SuperSU/Magisk flash is optional after the ROM flash. I see that you are running 3.0.4-1 which is a 7.1.1 compatible TWRP so there is no need to worry of any data loss. TWRP is also able to flash the OTA's provided you have not made any changes to your system partition and have remained unrooted.
You can come to General / OOS thread and ask there for further understanding :fingers-crossed:

You can flash OTA as long as your kernel is on default, what I mean is stock/untouched which is basically same situation as yours since youre unrooted. ? So yes you can flash OTA no need for full flash

If me, i like waiting full ROM zip release and do clean install.
Sometimes, flash OTA getting error (cause root, bla bla bla hahaha )
Yeah, it could be lazy gonna install back all apps at least you backup it
My advice, if you update same Android version, no problem to do a dirty flash (same ROM like LOS 14 to LOS 14, but if different ROM, i suggest better do clean install)
But if different version, mean 7.0 to 7.1.1, better clean install (dirty also no problem, but wonder in future got problem)
But hey, different people, different way right? This just my 2cent

It is my understanding that when moving from whole version number changes (6 to 7, 7 to 8) etc that a clean install is definitely way to go but even from 7.0 to 7.1? Also when you download the OTA, is the file saved somewhere so you can then locate it in TWRP for flashing? I don't want to allow the system to install the ota automatically correct?

It is best to clean flash if you've major upgrade like 6->7 or 7>8 something like that but if as your question you're still on marshmallow so you can flash OTA zip through twrp and make sure after OTA you've to flash twrp again to maintain it. If the system shows OTA it can't flash it via open recovery on twrp, you must have stock recovery to do it.

Ota update for pixel 2 xl with magisk and twrp already installed

I am sure this has been asked and answered 100 times but for the life of me I can't find a definite answer. I have a Pixel 2 XL and it is rooted and I have Magisk and TWRP installed on it. I want to be able to install the OTA for this month, but I do not want to lose anything on the phone. I also would rather not lose Magisk or TWRP. Normally on my android phones I use ROMs and can just update through TWRP, but I want to stay on stock because I don't want to lose Active Edge. So can someone please help me by giving me step by step instructions or point me to instructions that are simple to follow so I can take the OTA?
I really appreciate the help.

I was having the same problem and was helped by some of the members here.. Best way is to flash the firmware after removing the -w from the flash all file. Then flash twrp and magisk.
Ota

Thanks for your help. I will try that.

Here's a quick little guide I made for updating monthly factory images. Hopefully it'll help you out :good:

Sorta related...
Are there any ROMS that come rooted so I don't have to go through the monthly process of backup/unroot/update/root/restore?
Would love to just flash a ROM update and be done.

Hi, quick question
I am only able to do them steps above if I have done 'fastboot unlock_critical'? I have only done 'fastboot unlock'
Also I would need to boot into TWRP and flash a kernel + magisk to retain root?

You have to issue the "fastboot unlock_critical" command in order for the bootloader to update, since the bootloader is included in both factory images and full OTAs. Speaking of full OTA's, one of our recognized developers, @elliwigy, revealed (thread here) that it is possible to flash a full OTA image through TWRP, which eliminates the need to open the factory image and remove the -w flag from the last line. Flashing the OTA works because TWRP doesn't check signatures like the stock recovery. You will lose both root and TWRP upon reboot however, so you will still need to connect to a PC in order to reinstall TWRP so you can subsequently replace the stock Kernel with the Flash Kernel and then root.
I can verify this works, as I tried it with the May update.
