Welcome to Android!
I'm sure you'll have a lot of fun
Typically you'll find a tab saying root info for each phone model in the forum. However, these tabs (same for ROMs) are typically not as updated as the forum threads. You'll find most info/guides for that kind of stuff in general, seeing how in most cases in concerns the phone in general, more-so than a specific development for the phone (such as a specific phone).
Make sure you carefully read the original post for each software seeing how different softwares can only be used in certain situations. For example, the LG G3 comes in different models, and some software only work for the specific ones, some things are developed for certain android versions (such as lollipop vs. kitkat), some softwares are developed for stock-based roms, and some are developed for aosp-based roms, and the list goes on.
It's not as complicated as it sounds, and it doesn't take as long as you might imagine to get settled, but it takes some getting used to.
To answer your specific questions:

2) how to make a custom rom and how to install

1. After you've rooted your phone, you need to install a custom recovery (http://forum.xda-developers.com/lg-g3/help/help-thread-lg-g3-question-t2947298, check Q4).
2. When done with that you download a [ROM (whatever the rom is called)].zip (http://forum.xda-developers.com/showthread.php?t=2772658), and typically Gapps, and place on SD card.
3. Boot into recovery, and wipe the phone (I usually go for factory reset/make fresh install + wipe cache + wipe Dalvik-cache)
4. Now you need to flash the ROM + gapps. Do that by install zip --> install from SD card --> click the [ROM].zip (and then gapps)
5. Reboot and enjoy!
3)How can i find the right stock rom for my phone and how to return to stock rom (I have the 32 Gb model and software version V20h-EUR-XX)

I'll admit that I have not read the specifics of each thread I've linked, so make sure that it applies to you before you go about and install stuff (by reading first post in each thread). Also, how you install might differ a little from rom to rom, so only use my instructions as additional instructions to the instructions typically written in the first post for each rom/software.
Note! Everytime you go about fiddling with the phone you do run the risk of bricking it. However, the risk of hard bricking your phone is quite slim as long as you read up a bit before messing about. On top of that, if anything would happen, such as a bootloop or soft bricking, just keep it cool. It happens to all of us from time to time, and I'll bet you that the very same thing you did wrong, has happened to someone before you, so just search the threads (starting with the thread it relates to). If you feel like playing safe, I would suggest you start off with one of the more established ROM-devs, such as CM.
I hope this helps!

Thank you munte89 for all your answers.i hope all this can help me.I have one more question.
LG G3 has 2 versions.16 GB & 32 GB .Is the firmware same for both or has each device his own firmware ??

No worries! I know it can be difficult getting started
Well, it's different firmwares sometimes (eg different stocks). This is typically clearly pointed out in the instructions if that is the case. I have not encountered that where it comes to the custom ROMs, except for making sure you have the right model (eg D855). After you've installed a new ROM, you might want to go to settings --> about phone to check the information for any clues of using the wrong software.

Bought a G3 , What do I do now?

Hey guys, I've just received my new G3
My knowledge with android phones is very weak, having only rooting my 1st Gen Nexus 7 to and flashing stock roms & owning a windows phone .
Is it worth flashing a new rom to my G3 or should I stick with stock? Any ROM's which are highly regarded? How would I do this + root?
I will be having a 32gb memory card in this phone, Is it better to install everything on the SD card in the first place e.g apps,pictures e.c.t. so if I decide to flash a new ROM I wouldn't lose everything.
Also is there any way to get my contacts from windows live onto my new phone?
I would greatly appreciate your help
* Use it !
* be aware of the sd card, it should be a modern one so you don't risk performance
* don't bother installing stuff on the card - apps are lost anyway
* you can keep personal media / pics / etc on the card, that is a reasonable practice ...
* the current state of software (lollipop) doesn't allow root / flashing stuff; however there are options for kit kat (if you are still on it) and moving then to lollipop keeping your custom parts that allow third party flashing (my 2 cents this is not worth it at the moment ...)
* moving contacts along should be easy by either syncing them to some cloud service (outlook maybe) or exporting / importing them - LG software knows how to import popular formats ...
If you are new read phone FAQ then.
Root it and install xposed framework

As above. I was looking at the AndroidNow HD rom which seems to look good but is it worth the upgrade over stock?
At the time of writing this, I've successfully rooted my G3 & my current firmware is 4.4.2
how are you finding stock? is it a smooth experience?
im getting mine tomorrow and going on holiday on Saturday so i need to make sure i have the best experience =D

It allows you to tweak a wide range of things, it's fantastic, but only works on Dalvik, not Art. So you have to use KitKat.

[Q] New G3 owner with some questions.

I checked several of the threads in the various subforums but since I am currently really busy (have the phone for 3 weeks and I am not using it cause had no time to check XDA ) if you are kind enough I have some questions that spending more time in the threads would probably answer themselves but alas...
A: If I root the G3 can I bring it back to stock without any indication it got rooted (I heard some phones have special logs that show if a phone has been rooted that survive the various flashes), in case I need to send it for service?
B: Should I go with the root method shown on XDA TV (which doesn't show how to install a custom recovery) or one of the one click auto batch scripts?
C: I think generally this question is not allowed cause it can lead to flame but which ROM would you recommend I try first? I need just a clean, smooth running ROM. Disclaimer: Avoid arguing with other users if you disagree with something they said, just state the ROM and if you want your reason for picking it and I will scroll through them and decide.
Much obliged if you care to answer them and apologies to mods if this breaks any rules.

A: You can always go back to stock using LG flash tool with no evidence of rooting nor like samsung's knox
B: http://forum.xda-developers.com/showthread.php?t=3072767
C: I personally use resurrection remix rom based on CM12 due to performance but if you want fully working G3 with no bugs at all I recommend my favorite rom CupaChups 4.2. Super fast stock base rom with some extra features.
P.S. I recommend you to instal Kernel Adiutor from the play store after you root your G3 and change the governor from default Interactive to Conservative. Cos from some unknown reasons the Interactive governor is bugged on all G3 and changing that will highly increase your performance speed and feel. This works with base and aosp roms also.
Hope this helps
via LG G3 @ Resurrection Remix
Thank you, is there a problem if the phone is already on stock 5.0? Can I still root it with the same methods or must I restore it to 4.4.x? (A simple restore to factory blabla does it?)
Cheers

If you have a look around there's a one click method that works for all G3 variants regardless of software version that is here on the forums. You can use that, download the zip for your desired custom rom, install a custom recovery and then flash the ROM and you should be good to go. There's plenty of guides for you to use, and each custom rom thread should have it's own installation guide

[Q] Step by step guide for stock Lollipop on G3?

Hi,
Absolute complete newbie here when it comes to any type of fiddling with Android. I have no idea where to start.
I used to have a Nexus 5, I loved the stock experience. I now have an LG G3 D855. LG's version of Lillipop is fine but it's no where near as good as stock.
I know the G3 can have stock lollipop put on it but I have no idea where to start. Is there a step by step guide somewhere I can use or would someone on here have the time to write one up for me? (A lot to ask, I know so I won't be offended if you say no!)
I'm not a total newbie in regards to tech. I've build PCs and all that. I've just no idea where to start with android or how to change my phone.
Thanks in advance if anyone can help.

Moving to Stock LP
easiest way to get to LP is by getting your current firmware from here: http://lg-firmware-rom.com/
then upgrade to that kdz from with lg flash tool 2014, from here: http://forum.xda-developers.com/show....php?t=2797190
also need LG Mobile Support tool: http://www.lg.com/au/support-mobile/lg-G3-D855-Metallic-Black​
Root & Custom Recovery
root with this tool: http://forum.xda-developers.com/lg-g...lipop-t3056951
then install twrp with this http://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396
keep up to date of LP updates with http://forum.xda-developers.com/lg-g3/development/stock-t2961073​
i also think you have your terminologies confused; what you call 'stock' i think you mean the google nexus software or 'google edition'. 'stock' in fact refers to the firmware that LG pushes out. the other option would be 'custom', which is where you install software not made or endorsed by the phone's vendor, such as Cyanogem Mod. to install these 'custom' roms, you'll need to be rooted & have a custom recovery (twrp) installed to flash said 'custom' roms.
for me, i have stock LP and use tweaksbox, which customizes many aspects of the software. if you're interested, i can run you through on how to get it, because there are a few things you need to do.

Questions about rooting from a noob.

Hi guys, I'm thinking of buying an LG G4 because it's gotten very cheap now and I want to use it as my daily driver.
I'll be getting the international version and I want to root my phone before properly setting it up. The reason for this is that I want xposed to make some ui changes as I feel the G4's ui is horrible (no offence). I've heard I'll need a custom kernel, twrp recovery, unlocked bootloader and root access.
I've also heard that with custom roms you lose functionality to things such as the IR blaster and the amazing camera app and all its settings. Is that true? If that is the case, I'd rather keep on stock rom with xposed helping me make the UI bearable.
My question is what would I exactly need to do? (with kernels, recovery, bootloaders etc I have only rooted a device once and it was 4 years ago so I have forgotten the basics plus it seems the whole process has become very tough now) The only end product I want is to run the xposed while retaining the IR blaster functionality and the camera app etc.
I have tried going through some videos on youtube but I found them vague, a little different from what I wanted or I saw a few comments talking about how the phone was bricked or stuck in bootloop.

Hi buddy , if your phone comes and it's on lollipop the type in Google " root lg g4 lollipop xda " but if it arrives on marshmallow then type " root lg g4 marshmallow xda " as for losing functions like the IR blaster and camera , I'm using latest Genisys ROM marshmallow version with the Imperium kernel and I have all my features still working they will only stop working if you flash a ROM which isn't based on LG for example Cyanogen or blisspop things like that....
If I have helped please leave a thumbs up!

Hi, thanks for the reply! How is the performance compared to the stock rom? What other benefits does a g4 based rom give?
Also, I still find the process a little confusing. Am I supposed to root first, unlock bootloader or install a recovery. Also what are the chances of bricking my phone?

Well first of all the performance depends there are options when installing different kernels which will give you better speed or better battery life the choices will be written in the kernel or ROMs description , the other benefits are debloated ROMs which means the software on the phone has been reduced to free up space and get rid of useless stuff and other little UI tweaks it just depends which ROM you choose as for the process you unlock your bootloader first via lg devs official site then depending on how you root will depend when you root it I'll explain , if your phone arrives and its on lollipop then use low effort root but if it comes and its on marshmallow then you use systemless root method and I won't bull**** ya pal the chances of messing your phone up is about 30 percent just make sure you follow every single step very carefully , the reason I said 30 percent is because if you're on lollipop then it's easier in my opinion to restore your phone by flashing the .kdz stock file for your phone ( the .kdz will make your phone like you bought it)

What are the advantages of the rom that you're using?
30 percent sounds like a lot, but are you saying that I can restore my phone even if I mess up the process?
Also can you link me to the methods?
The advantages of the ROM I'm using is good battery life with a good balanced performance also it has the LG G5 apps built in to it , and yes you can restore your phone as for the links to the methods I'm chatting to you on my tablet so gathering all the links would be quite hard they are easily found though for example if you are searching for low effort root then just type it in Google followed by xda so it looks like low effort root method xda , if you really want the links then I'll boot up my PC in the morning and I'll find them all for you , it's night time where I am so I'm going to bed soon I'll check your post though in the morning in case you have any more questions and as always please leave a thumbs up I greatly appreciate it , thanks buddy....

No problem mate, I found the link to the low effort btw.
So I'll have to unlock bootloader via the lg website first? then I'll have to install a custom recovery and then root? (or root and then install custom recovery?)
Also I was going through the thread of the rom you're using, and I saw the screenshots and they were pretty much the same as the lg ui (which I'm trying to run away from). Basically what I want is a stock android ui without losing the core functionality like the IR blaster and the camera app, knock code etc.
A question I have is do I have to change the kernel etc while rooting my device or can I just use the stock kernel?
I just did all of these things this morning. I posted my steps here: http://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003
I personally stopped installing custom ROMs since Xposed. It lets use keep the phone as it is out of the box but add in just the changes we want. With many custom ROMs, there are always bugs so you'll have to update them and that can mean resetting your device. You then have to install all your apps and settings again.
I tried to make the above guide as noob friendly as possible and it hopefully shouldn't require any reading outside of the thread.

sm-t110 (only root or install rom?)

Hello everyone,
this is my first post in this forum, so i'm excusing in advance if this is the wrong place for this post.
I have a samsung tab sm-t110 which is very slow on every action. I try to format it, but I see no improvement. I then look around to know a little about root and roms.
I read several thread in this forum and i have some question.
1) I'd like to speed up my tablet and remove unnecessary apps, do I just need to root it? If yes, can you confirm is this thread the one I need to follow carefully?
2) What action do you suggest to do after?
3) If you think it would be better use a rom, which one do you suggest?
Sorry if my questions are silly, I'm new and wish to know better this world before starting manipulating my devices
And thanks to whoever will spent his time answering
As far your device, you should first root it . And thn use 3rd party soft wares to delete the unnecessary apps. This will help a lot and you can also download Lineage for your device .
I root the device successfully
Thanks for the clean and easy-to-follow guide (can't write in the thread, it's closed)
For now I'll try using the rooted device with some app.
Really last question for now, what would be the best ROM? The Lineage OS that seems will be out for the end of July?
Its cynogenmod
