Question Concerning LG G4

Hey guy, sorry if this is going to be a bit of a noob question but please try and bear with me. In lieu of the recent nexus 5x which i found to be a huge disappointment I decided to pick myself up an lg g4. I'm not the biggest fan of the stock lg Rom and immediately looked for Cyanaogenmod.
I know that no stable build has yet been release for this phone yet and that i just need to have some patience, but I have some questions regardless. I'm wondering if there is a difference between root and an install of cyanogenmod. By this i mean that there are certain installer which will complete the process for you without you having to do any rooting yourself. If i understand correctly the phone is still being rooted but just by a program. My question is, is it only this latter feature that is not yet available for my phone. Like, if I were to root it myself would I then be able to install a cyanogenmod ROM. Or is it that there is not yet any compatible ROM for my device. If it is of any help I have the LG-H812 version of the phone.
Also, I recently saw a video on the XDA developers YouTube channel where it was discussed how TWRP is now available for the G4. what exactly does this mean and is it something that I would want.
Thank you very much for putting up with me.

Sounds like you need to do a bit more research before you do anything. I don't think TWRP is available for your model at the moment, which rules out custom roms/cyanogenmod. You just have to be patient and hope TWRP becomes available, then wait for a stable rom to come along. Or trade/sell your H812 for the international H815 (careful there are a few variants of the H815).

He's right man you Really should start hammering google especially with a more technically involved root with our g4s. No matter what anyone tells you TWRP or another custom recovery is the number one absolute most important thing to do with any root and immediately after you root before you make any modifications beyond normal app installs whatsoever. Custom recovery is what is going to save your ass in a bootloop or brick situation where you cannot get to the OS or even get a response from the device. As long as you have a backup in storage, you can use hardware key combos to enter TWRP and wipe the system and the problem and reflash the backup. Recovery is completely separate from the Rom that's how you can get around a total Rom disaster when nothing else works. The main reason there's no Roms for them yet is cuz only that one variant's bootloader can be unlocked which is required in most devices to flash a Rom or recovery and the reason that even with my capabilities I won't even bother rooting my expensive ass main important phone I'm still paying for every month lol I just fulfill my flash addiction on an l70 on a daily basis and daily I get outta bootloop and bricks thanks to TWRP... The g3 is perfect for playing with and I'm considering buying a used one and o I recommend the same until the g4 is fully cracked......also CM only comes pretty rooted because it does the same thing as normal just by flashing supersu which is a breeze with TWRP also
Through my ancient eyes comes the certainty of decay... LG G4 & L 70

Verizon LG G3 straight talk, no internet upon downgrading.

I have a LG G3 from Verizon, If I downgrade to kitkat using the lg flash tool I have no internet or mms. I used LG Flash tool 2014 to boot a kdz file (24B) 5.0.1 lollipop and still had no internet. I connected it to my pc and updated it, now I have internet? From what i've read you cant change apn settings on verizon and you get what is set on the phone. Am I doing something wrong? I'm now on stock 5.1.1 which I have also read cannot be downgraded. I miss root lol

I seem to be able to downgrade to kitkat via tot files, I can text, call and get wifi just cannot get mms or data. I couldnt create a new apn with it being verizon so im assuming verizon isnt changeable? I dont understand what the difference would be. I am a complete noob to rooting, I know how to root by using either stump root, one click root or simple stuff, lg flash tool I just followed directions and it worked. I know I shouldnt be tampering with the unknown but it really interests me. I want to learn and I learn from hands on/trial and error. I have tried google for the issue and searching these forums, I think where I'm failing in my search is the wording. I see updates for "modems" but I dont know if that's for mobile data, tethering or what. I need to research it more. I'm trying to give as much information as possible and allow an understanding of how noob I am lol. If anyone can lead me in the right direction I would like to gain root access once again. Thank you in advance, I hope someone can help me.

LG G4 Root?

Hello XDA community,
I recently traded in my old iPhone for this new LG G4, and am so glad to be converted from iOS to Android! Anyways, one of the main reasons I switched is because root access would enable me to maximize the potential of my phone. The only problem is...I have looked vastly throughout XDA and other Android developer havens for root guides and have gotten so confused as to where to start. Can somebody direct me to the right place, or even better, guide me through the process?
Thanks!
(I am using the Verizon G4 (VS986) with Android 5.1.)

DId you have a good look through this thread?
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
It seems daunting but the first things you can do prior to the flashing are
-Get the software you need installed and tested
-Learn how to put your phone into download mode
-test to make sure your phone can communicate with your computer the way it should
-Download all the files you need (stock kdz and matching rooted image version)
Take the time to read each step, and if you have any questions, ask before you proceed, not after you have completed the step.
Good luck! The group here is very helpful so do not hesitate to ask.

I will definitely look into that thread! Quick question, what exactly is flashing? I know it has to do with modifying the operating system..but I honestly do not understand the purpose and benefit. Could you explain that to me?

Flashing is basically copying OS onto your phone and installing it.

Okay. So in this root you copy an OS with root permission?

Yes. With this method, you are basically putting a portion of the OS on that is already rooted. That is why it is important to make sure you have the correct versions.

Done?
I followed all of the steps provided in the link you shared, and believe that my device is now rooted! At least, I think and hope. How can I be sure? And if it was successful, what should I do next to make use of my root access?
Thanks again

You should see the SuperSU app. Open it, it may/should prompt you to update.
Otherwise, download root checker from the play store

Done! Now, are there any resources for what I can do next?

Rooting and upgrading SM-G3502T

Greetings, people of the XDA forums! I am Brazilian Slaughter, some anonymous brazilian from northern Brazil.
I am the owner of a Samsung Galaxy Core Plus (SM-G3502T) smartphone, android jellybean.
Lately, my smartphone has been getting in my nerves with its slowness. A few months ago, I have decided to root it. Someone somewhere in the internet has suggested me to root and install Cyanogen, because the default samsung interface is slow crap and putting Cyanogen would make it faster.
I went researching these days, and found that Cyanogen is dead, LineageOS is in its place. But, searching and asking, i found out that LineageOS has no official support for my phone. A guy in reddit did tell me there was a unnoficial build for my phone and I should ask here.
So, here I am. I got my files backuped already. I plan on rooting it and installing a new ROM. But...
1. Which is the best root program? I've heard of Kingroot, but people told me its shady chinese ****, so I should go with SuperSu, Xposed or another program (something with magic whose name I forget).
2. Which is the best rom to install? Is there a unnoficial build of LineageOS for my device? Is it worth it? Should I install something else? If so, what?
(is this the right section? I hope it is)
Thank you for the help!

You can't put anything custom (no Custom Recovery and no Custom ROM) on the SM-G3502T, because it has a locked bootloader (I wrote something here: https://forum.xda-developers.com/android/help/samsung-galaxy-core-plus-trend-3-t3524989 )
That means in 1) that you can't flash SuperSU, Xposed or Magisk (you probably meant that) and 2) is completely impossible
You may be able to root it (can't say how, I don't have this phone, I heard that vRoot, Kingoroot or Framaroot should work though, there is a script too which replaces it with SuperSU).
If you can't root the phone (or fail somewhere and it is bricked), get the stock firmware from http://www.sammobile.com/ and install it through ODIN (If you need I can send you a few links on how to do that)
EDIT: Added link

Thank you, Tim Schumi! This post was very informative!
I better not risk rooting it for now, learn more. I think I know someone who might get it done. I might get a new cellphone soon - or better saying, mom might get a new cellphone soon, and I will get hers'. Once I have a backup I can risk it freely.
This is a good phone, but it has some annoying useless **** it totally does not need, you know?

You can always flash back your Stock ROM via Odin (unless you really manage to overwrite something like the bootloader). But yeah, you better wait until you have another phone so you can try stuff with this one.

LG G Pad VK700 (Verizon LTE) - ROM options?

I'm sorry if I'm asking something that's been answered already - I've searched and have found some discussions of this model, some discussions of custom ROMs for other models, methods for rooting this model (which haven't worked for me (script fails at the last step)), but nothing outright stating what my options are for this tablet.
I inherited an LG tablet that was apparently sold through Verizon - it has a Verizon bootsplash and some custom Verizon carrier-installed apps. The hardware info in settings shows the model as "VK700" and the back of the device has "LG-VK700 | FCC ID: ZNFVK700" printed on it so I'm not sure if it's a G Pad 10.1 or something else.
I'm trying to see what's available to me in the way of custom ROMs without Verizon-installed apps (that are useless to me), future updates, etc. As I mentioned, I've tried numerous means of rooting (The LG one-click root method here, the "New root method for LG Devices" here, KingoROOT on my PC, and KingRoot on the device itself. None have successfully rooted the device according to a root-check app, so I'm not sure what I'm missing/doing wrong, or if it even matters. I was under the impression that one first needs root in order to flash a custom ROM but who knows if that's even relevant.
I suppose what I'm really trying to figure out is whether I'm stuck using this thing as it is or if there's something better I can put on it (Lineage? AOSP? Cyanogen? Not sure what's out there and I've not followed the Android dev scene that closely.) If there is something better, can someone make a recommendation and link me to a good, comprehensive and easy/straightforward guide to installing it? I would be most appreciative of your time and effort.
Thanks.

ok im pretty sure that the lg lollipop bootloader isnt bumpable ( not bumpable on my tab) have you tried downgrading to kitkat because thats what i had to do to bump my bootloader but im not seeing any roms for your device which is kind of funny how my tab has more roms then your tab but we dont have our own device forum weird but i dont see any twrp for you either also if you want root try the kingoroot not on the actual kingoroot website go to https://kingroot.en.uptodown.com/android/download the version on the kingoroot website doesnt root our tabs for some reason so use that one oh i just found a twrp for your vk700 https://www.needrom.com/download/twrp-3-0-2-2-vkworld-vk700-pro/ but probably no use without custom rom
