Root Exploit for Tmobile LG G2 Kitkat

Have updated my Tmobile LG G2 to Kitkat and want to debloat it (as I actually like the LG UI). However everything I google about Rooting just links to Kitkat being available but not how (or if) you can root it.
I assume that IORoot22 will only work with 4.2.2, and vroot/kingofroot don't work either, so does anyone know a way to do this?
Thanks in advance

This should be in the Q&A section

there is currently no way of rooting T-Mobile's Official KK update.
your best option at the moment is to flash back to 4.2.2 via KDZ > Root + Custom Recovery > Flash SmiLey's Stock KK ROM ( http://forum.xda-developers.com/showthread.php?t=2664652 ) > Flash SuperSU zip before rebooting (Recovery will be lost after reboot).
or wait until an exploit is found, there are at least 3 threads discussing this exact thing in the G2 General Section
edit: This thread seems to be the most promising so keep an eye on it (http://forum.xda-developers.com/showthread.php?t=2667227)

Must have been moved it was originally in the Dev Section.

Okay, I somehow rooted my tmobile LG G2 with Kitkat, ran for awhile than did something (don't know what) that removed okay google function from home screen and slowed the google search to a snails pace.
So, like an idiot, I thought I'd just put it back to stock with the D80120a.KDZ. rebooted and restarted everything. BUT the phone still shows rooted in download mode, but rootchecker says I'm not rooted. Also tried to run SuperSU but it says no binary and won't load. Tried Flashify (to try and flash the SU zip) but it also said I couldn't flash because I'm not rooted.
So I ran LG R&D, none of my phone info shows - ran upgrade trying to return it to D80110c/g, but each time it says I'm current and nothing happens.
Have googled every possible search and can't find a fix.
No longer have recovery, because of the stock flash... So I'm in dire need of assistance. Can anyone help me?

[Q] Is it currently possible to root an AT&T Galaxy S4 (1337) on 4.4.2?

I updated my Galaxy S4 (1337 AT&T) to 4.4.2 KitKat, without realizing that I risked the possibility of not being able to root my phone for a while. Is there any way to root my phone right now? If not, when do you think a root method will be available? I use on a mac running OSX Mavericks at the moment so if there are any methods specifically for macs then please do let me know. Thank you! :laugh:

You can downgrade to a semi-working 4.3 firmware and then flash a pre-rooted 4.4.2 rom using safestrap. Although this method requires you to use odin at the end so idk if odin works for mac or not.
Further details discussed here: http://forum.xda-developers.com/showthread.php?t=2692825
There is no traditional root method available, but the root-workaround is an excellent solution to gain root access.

Thanks, when do you estimate a traditional root method will arrive for my phone?

There is no estimate. For future reference, asking for any kind of estimated time is generally frowned upon as the insanely hard working devs here on xda have a ton of stuff on their plates BEFORE you add in actually working on any device. Not trying to sound like one of those asshats that gets all bent out of shape about people who ask for an eta, just giving you the heads up.

Well, with a working root method already available, most devs see no reason or motivation to do something redundant. Since root access is already available.
If our bootloaders were unlocked, then we would be able to use Chainfire's CF-autoroot method.

If I root like this, will I still be able to install custom roms?

Yes, but you are limited to using Safestrap and Touchwiz ROMs.

Heimdall is generally used on the macs--I haven't needed it but you can google and get familiar--I found numerous sites and some are on xda. Always good to read all you can and kinda reconfirm what one site may say or find out it wasn't right for you.
if you haven't this link should help you get adb working on mac
http://forum.xda-developers.com/showthread.php?t=1917237
best advice was already given by 4ndroid99's link and also get very familiar with SafeStrap for your build. Threads for that are on our forum here also. You can't flash custom recoveries, just what SafeStrap provides.
Also, I have never had luck on my iMac with Keis and my rooted s4--recommend not using it
Good Luck--:good:

Another upgrade

Guys, my phone just told me there's another upgrade for the lg g2 D803 variant....Anybody seen this yet?
I'm wondering what the upgrade is, seeing it's 1.5 gb.
It's gonna take me to D803B20G. Not sure if the current rooting and autorec recovery method will work on this new firmware, sceptical about installing it......

1. wrong place to post this.
2. general rule of thumb - if you like having root and recovery, NEVER take an OTA from the manufacturer EVER, until it's confirmed that it doens't block root / recovery /bootloader exploits (like the 4.4 ot'as blocked loki)

Q&A if you're asking a question about it, General if you wanted to let people know about it..

yes probably in q&a or general maybe, like stated above please dont install on your phone if youre rooted with a non stock recovery otherwise you will mess up your phone big time! really not sure if its possible but if you can, switch off firmware updates as they are not compatible with the custom recoveries and whichever rom you are using will update soon enough anyway if your on stock rom the same applies if you have a custom recovery

I have stock Rom rooted and twrp recovery that's all.

Avoid the update.
However it has the knock knock code addon. Or, as far as I've heard, that's the only new update LG had planned for the LG G2.
Do not install it. If you REALLY want to try it, make a backup, store it on your PC, OTA. If you lose root, you can revert to stock, get a recovery, put your backup back on your phone and restore.....but that's honestly a lot of work just to possibly get the knock knock code. (I know turning on is knock on, but for the "code" you knock more than once minimum, so I call it knock knock).
You can also force supersu to keep root, but last time I tried that for an OTA I got stuck in a bootloop.
TL;DR: Might be knock on/knock knock code. Not sure what else. You can backup and try to OTA, but no one can be certain what will happen. Expect to lose root. You can force SuperSu to keep root, but you may bootloop.
I'd just wait for more info.

twrp recovery is a custom recovery, so never update.

I'm pretty sure there is an app in /system that you can freeze to stop push updates. Sadly, that is the only info I have. It may have been carrier specific and I haven't been on stock since the first week I had the phone. Haha.

Guys I already know all what you just said......I've done this loads of times. Just wondering if I can uninstall custom recovery without re-installing stock firmware?
I know I can take my chance and try the OTA but not without recovery gone first.
It's a lot of work to just flash stock firmware, install update and if there's no big change, flash stock again.....
Thats why i was wondering if the only option is flash stock to get rid of recovery

I think its possible, (but it should be really hard to do so) but the easiest way is to flash a .kdz file And you should not take the chance to update when you have recovery, it just isn't worth it. Anyways I would just have sticked with a custom rom which gets updated regulary..or flashed a kdz and get back to stock.
Btw can the good judger @Judge Joseph Dredd move the thread to q and a section? I think that it is even more help to get there

[Q] Rooting LS980ZVE 4.4.2

Hey guys, hope everyone is doing well.
I purchased a used G2 a couple weeks ago and activated it on the Sprint (Ting) network. The previous owner seems to have made a failed attempt at rooting the device; There is a SuperSu app in the app drawer but it doesn't work (missing binary) and RootChecker fails.
I've tried using StumpRoot but the "Grind" button is greyed out, as well as IORoot but the flash fails.
If anyone has any tips I'd really appreciate it. Otherwise, if you need any more information about the device just let me know and I'll be sure to post it!

same problem
Android Noob
I just got my g2 ls980zve 4.4.2. My device is not rooted but stump root keep saying your device is rooted. And i couldnt find a proper root guide for this update. Help...!

Best solution: use one of the ZVC tot files and take it back to pure stock, then do the OTA upgrade to ZVD, then ZVE, and use Stump Root nice and clean once you're back on ZVE.
That's my recommendation. Yes it's a bit cumbersome but if you're going to be pure stock (rooted, of course), that's the why I would suggest it be done properly. Trying to "fix" a busted root or one that didn't get done properly could cause more trouble than it's worth. You could do the reflash to pure stock ZVC in a matter of minutes, then the ZVD - ZVE update in a few more and have zero issues whatsoever.

Or flash the zve tot and then use stumproot.

Didn't realize there was a proper ZVE tot file available, would have suggested that if I did but yep, that's even easier and the best solution overall.
Neat...

I am having the same issue, glad to see a solution.
It may be a stupid question, but since I do not know the answer... Where do I find the ZVE, or ZVC files to load? If someone has a link for a thread kn this subject that would be very helpful. In the mean time I will be doing some more searching.
Thanks!

Thanks for the responses guys, really appreciate the pointers!
I'll definitely be trying some of these suggestions when I have time First week back at Uni is kicking my ass so far lol!

Rynglade there is a guide to restore to factory in the lg g2 general section at the top. Internetcommand. if the previous owner attempted root then failed,stumproot will not work as it still detects the phone as rooted. the only way to get it to work is to do a restore with lg flash tool.

@broadband and rularn
Thanks dudes

Hey guys, quick update as I've finally found time to try working on this:
The only issue I'm having right now is that my phone will NOT go into download mode. I've tried several times and nothing seems to get through.
I really don't know what to do from here since I can't flash a stock firmware without going into download mode...

[Q] Need Help Updating AT&T S.Galaxy 4 V. 4.2.2 Rooted to Newest Version AT&T

Hey guys,
I ran a search but I don't understand half the things people are writing. I would greatly appreciate it if someone could please explain to me my options. In layman's terms, as I do not understand half the abbreviations and jargons here.
I rooted my phone over a year ago and really don't remember much about the process. I can't download important apps from Google Play anymore as they require newer versions than 4.2.2... So I'm stuck on this old version and need to update ASAP.
I have ONLY rooted the phone. I haven't done any mods or installed any ROMS. It's on stock AT&T Rom. (sometimes I wonder why I even bothered in the first place).
Can someone please point me in the right direction, I want a regular STOCK AT&T newest version, whether it stays rooted or not that's fine, but a newer version, KitKat preferably. What are my options? The simplest method would help me the most.
Things I really need backed up: My Text Messages, Voicemail, Call Logs, Whatsapp Messages etc. What is the best way to back that up? If I use Titanium Backup, and I don't have root after I update, Titanium Backup would be obsolete. So what would my other option?
Please help.
Much appreciated,

Are you sure you want to update from 4.2.2. You probably have the option to flash custom roms on your phone. There are many custom roms that that'll put 4.4.4 on your phone. Since you're rooted get terminal emulator from the play store. In it type
getprop ro.bootloader
If the last three characters are mdb or mdl you have a lot of options. I can help walk you through on how to get a custom rom on your phone.
You can update your firmware and bootloader to 4.4.4 too but you'll lose the option to flash most custom roms.

Thanks bud,
I got I337UCUAMF3
I'll be honest, I haven't really messed with any custom ROMS before. I just use the stock AT&T one. But I would like to upgrade to KitKat so my phone is faster and can download / upgrade the latest Apps. Lollipop isn't out for the AT&T Samsung S4 right?

Will the phone Not download the latest 4.4.4 from the phone settings?? Settings/More/About Device/Software Update. It must be connected to WiFi to download!!!

No. My phone is rooted... Is it supposed to download to 4.4? And also couldn't there be issues with that?

I found this post. So I know this is ONE option: But I'll lose my Root. Which is fine if that's my only option.
http://forum.xda-developers.com/showthread.php?t=2728462
As the OP says, I will lose ROOT. So my question would be, If I back up using Titanium Backup, how can I restore my backup if Titanium Backup works only on ROOT? This is very important.
@ jd1639 - He had mentioned there were several other options, so I will wait to hear them, and I can make a decision from there. Otherwise, I may have to fork out another $150 - $200 Bucks on a Samsung Galaxy S5 or S6. depending which suits my needs.
Many thanks for the replies!

You're on mf3 bootloader which doesn't really allow you to flash any roms anyway. You'd have to use safestrap.
What I'd do is flash the nb1 tar file in Odin. That'll update you to 4.4 and the device should then ota update itself from there. You will lose root, you can root it again if you want. See this http://forum.xda-developers.com/showthread.php?p=50912149

Thanks JD, do you know if this wipes my phone? In other words, does it factory reset my phone?

Yes Flash the NB1 Stock file as he said. But you are going to loose Root and any pictures etc. stored on phone memory, so copy them to your PC or SD card. I always like to take SD card out just in case when I flash just in case it may erase it. But after you flash NB1 Stock or the Stock Root it is like a phone and have to set it up. Then it should Update to 4.4.4 itself from the settings/ Software update. Good luck. Any problem let us now.

Ah cheers,

It's possible to root even the 4.4.4. It just gets a little trickier to do it and you have to flash modules in Odin. In the general forum see "all things at&t....." by guut13

Yep I think you are correct. So if you want to root again use the Rootable to flash in Odin. Once you go from Jelly Bean to Kit Kat bootloaders are Locked for some .tar Same for Lollipop, they have not been able to root and unlock bootloader as yet. Just follow the steps and take your time and all will be good. Have done it several times on mine with Odin.

Hey guys, I just wanted to take the time and thank you both for the help. I finally updated today. After backing up all my data and making sure everything was safe to go. Bam! I did exactly as you suggested and had zero issues... I am now on 4.4.2
There were a couple hiccups along the way, but I figured them out without too much of a hassle.
Cheers again and best of luck to the both of you!
