Hi All,
With all the threads about bricked phones, I wanted to take the safer route and outright ask for the best method to upgrade to KitKat on a rooted phone running 4.2.2 stock? I've already 'bricked" my phone once last year doing an OTA update, so I'm trying to avoid doing that again. I know this is a noob question, but I haven't been able to locate a sprint specific guide consolidating all of the information out there. Any help is appreciated.

The second post as you read will give information I thought a bit more clear on Sprint.
@#***This will wipe your phone as in complete. Nothing will be left of yours. So copy anything off internal [email protected]#***
Follow the directions, use ioroot25. Root.
If you want custom recovery.

Use auto-rec from above thread. Thank cloudyfa for putting that together.
If you reboot after and screen shuts off and you get white lines.
You might a well tot back to zvc and just root. @Cloudyfa on that same thread is working out the details to fix.

Thank you for the reply. I'll give this a shot tonight!
I have a question: I already screwed up and applied the KitKat update to my rooted G2 without thinking. It's now stuck booting to TWRP, where I was a moron and of course didn't create a backup at any point. Is there a way for me to sideload the ROM onto my phone at this point?
Any ideas?

Even sideload may not help you, if you can access down load mode. You might get to use tot, back to stock.
But there is no stock zvc yet for ls980.

Thank you for that suggestion. I was able to use Download Mode to fix my G2 and then OTA the KitKat update. Your post saved my phone.

I must have gotten lucky...wasn't thinking and took the OTA a while ago. Lost root but phone is fine.
Now...I'm off to find it again so I can get tether working

To the OP, can I ask which method you chose and how it went? I need to do this as well and I'm in the same boat as you (rooted ZVA with custom recovery).
Thanks.

I actually read a bit more and decided to hold off on the update. I'm happy with my phone's performance, so I really don't have the time to troubleshoot should the update go awry.

I'm the same way, but I figured that I should just go ahead.
So I'll throw that out, anyone pick one of these methods have a preference? I'm on TWRP, rooted, stock ZVA. Some mods including tether and camera. Thanks.
I just received my G2 today. Should I update to 4.4.2 before I root. Or is it easier after the update. It seems to be the same process for either, the only thing that im a little confused by is the zva, zvb. What exactly that is. From what I read it just seems like the names for updates. Correct?
I updated from zv8 to zvc (step by step). Then I rooted using adb bat file.

I'm still using stock unrooted, but I'm wondering if I root my G Pad only without flashing a custom recovery and ROM, will I still be able to update via OTA like usual or I have to unroot first!
Thank you very much in advance!

In the past several people have reported problems when taking an OTA update with a rooted G-Pad. Rather than risk it, I have always done a completely clean update with a wipe of the device using the LG Tool Upgrade Recovery with my V500. Once that completes I re-root the device and continue on.

Even if you don't have a custom recovery installed? Because I saw that some people with root only updated their G Pads ota with no problems with only root removed afterwards! They may have lied however!
I think this ota update with root problem applies to most android phones, right?
Thanks for your help

In my case, I have root on stock recovery, and always do the updates via OTA, without any problems, and without losing root after that!

Excellent, it is good to hear that root without changing recovery could work when taking an OTA update. I was only quoting what I had read, not what I had personally experienced. If it were to fail I would assume you could always use the LG Tool and do an upgrade recovery to reimage the entire tablet.
I did the latest OTA update (while drunk) and it updated fine and I still had root when I woke in a panic the next day wondering if I had soft bricked it.

A few months ago my g pad was root and I successful updated it to kitkat via ota update. But recently it showed up another update on the tablet and when I tried update it, it failed giving an error. I think if u are running kitkat and are rooted then ota update won't work.

Thanks for your feedback guys! The G Pad community is awesome! I'm happy I bought this excellent tablet with awesome specs! Nothing can beat its value for money and great design!
I rooted with towelroot and hope I receive future updates! Never thought towelroot would make rooting so easy as with my previous phones, had to do some steps while connected to pc.
Hi all. Just looking for some info/direction. I haven't used my s3 for awhile. My daughter wants to try out Android so im going to let her use it for a bit. I just flashed back to rooted stock image. Didn't realize its still on 4.1.1 and boot loader is MG2. I've been doing some reading and the info is kind of all over the place. Anyone have any info on best/safest way to upgrade? Should I unroot and take OTA's...or flash a stock ROM....thanks for any info and tips.
I recommend flashing back to stock 4.1.1 ROM without root, then run ota updates until you got the most recent kit kat.

Thank you. That's kind of the way I was leaning. Im gonna look around for stock build.
Correct me if I'm wrong but I'm pretty sure I read you can still root after update?

If you are on 4.1.1 or 4.1.2, any update you install will require you to update bootloader and modem. 4.1.1 was the last full unrooted ROM available for AT&T. Everything else was OTA. Once you OTA to 4.3 JB or 4.4 KK please keep in mind that you can no longer downgrade the bootloader or you will brick your device.
But yes, you can still root the device as far as I have been able to tell.

Thanks. Hmmmm thats right. Guess I need to think about it and see if the upgrade is worth it.
The most recent KK custom ROMs will require a KK bootloader and KK modem.
So I went back to stock (no root) when I go settings and update it tells me there is no update?

Did you flash back to stock using the 4.1.1 ROM from sammobile.com?

I tried that and had same issue then I used Kies and same thing keeps telling you me no update available. Then something about it will recheck in case amount of time.

I recall seeing a post from another XDA member that said the update asked him to wait. He tried again in a few hours and the OTA update worked.
Just make sure you are not rooted and running a stock recovery.

If you have not upgraded yet, please be aware that if you are planning to unlock, you must do so BEFORE upgrading. Free unlock is no longer available after update, you will need to buy code, and these are costly, like 20 bucks

True...our you can see if your mobile carrier will give an unlock code. No guarantees...especially if under contract.

Thanks! I'm not looking to unlock. The phones no longer on contract. Just upgrade the firmware so my daughter can take Android for a spin. She's 12. She has already used IPhone and now she's on Windows. Time for her to try out Android.
I suggest unlocking now before upgrading as the unlock codes may not be that cheap. I know for the Canadian s3, it about $18.

Just because you are not looking to unlock it _right_now_ doesn't mean you won't need it in future. Obvious reason to unlock would be for example if want to use it when you travel. If you don't unlock it now when you can, you could end up never unlocking it at all. And really, why not unlock?!
I am trying to get my phone unrooted but a bit confused about the process. I am running h81010g rooted on my LG-H810 AT&T G4. I know there's a thread about using KDZ & TOT methods, but there isn't anything available for at&t phones. Any idea how to get back unrooted?
My reason for wanting the phone unrooted is cause of lack of any development for the att version, i would rather have later updates than wait around on an older firmware (not that att gets out updates in a timely fashion).
Use the same process you used to root with. The image you want to install is the UNrooted h81010g

I was trying to avoid using the PR firmware because it appears that there is no return to at&t software once this is done. I would prefer to return to at&t firmware unrooted if possible
Uninstall all root apps before flashing unrooted.img file or just flash then factory reset?
