Hi,
I purchased my wife a google nexus 7 last christmas and it has android 4.4.2 on it.
Wifi version only
It is 100% unmolested in anyway. She simply uses it for web surfing
I purchased her a new 10.1" tablet that will be here shortly so I will take the nexus 7 from her LOL.
To preface the rest of this post, my phone is a samsung galaxy s3, probably close to 2 years old, and am quite famaliar with rooting and installing custom roms, etc all with help of xda of course.
Once my wife gets her new tablet, I would like to root the nexus 7 and install a clean, simple, basic new rom that is de-oxed and rooted. I'm a pretty basic user and like to keep a clean minimal os, etc.
#1 The nexus 7 shows that there is a system update, I assume it's an os update but she never bothered to install it? Should I before doing anything else? Will this have an impact on rooting and installing newer roms?
#2 I assume the wug's toolkit is what I should to root, etc
#3 What is latest version that I can install that meet my needs for a basic, clean, rooted and de-oxed android version. I don't need anything fancy. Just quick and clean and maybe something that aids with battery life? I assume custom recovery is similar to the phones and that one can still use titanium free version to uninstall unwanted programs.
#4 Since I never used her tablet, is flash an issue these days with android and tablets?
I will use the nexus 7 for basic web surfacing and things of that nature. I would love to eventually install ubuntu touch as I only use linux on my home laptops but that is a convo for another day.
Any suggestions and comments are appreciated.
If there is something you need to ask to give me some suggestions, please do ask.
Thanks
1.- Yes, it's a system update. It's a Nexus so installing it won't have any effect on your ability to flash a custom ROM in the future.
2.- NO! Never, never, NEVER use toolkits to do anything, ESPECIALLY on a Nexus device. More problems are caused by toolkits than any other reason, and relying solely on toolkits will hinder your ability to fix anything should something go wrong, simply because you just won't know how to fix anything. Nexus devices are the absolute easiest devices to root, and are the perfect devices to use to familiarize yourself with ADB, fastboot, and just the basic ins and outs of that side of Android. You will want to use fastboot to unlock your bootloader, and install a custom recovery. From there, rooting is as simple as flashing SU, and you will likely be prompted to do so after flashing recovery. The whole process only takes a few minutes and will provide an invaluable learning experience. Read the stickies, that's where you will find the guide and the bulk of the information you'll need.
edit- this thread should get you started- http://forum.xda-developers.com/showthread.php?t=2381698
3.-Read the OPs of all the ROM threads in development and flash whatever you think has the features you are looking for. The functionality of custom recoveries are near identical across devices, just make sure you flash one that is specific for your device. You will find the threads for recovery in the Dev section as well, possibly in original development. Yes, you can still use Titanium.
4.- No issues with flashing, as long as you flash the proper files for your device. Nexus devices are VERY difficult to brick, so don't be afraid to get your feet wet.
I hope this helps, and if you have any more questions, don't hesitate to ask. Happy flashing!
Edit: and just an FYI, Ubuntu Touch is absolutely horrible and isn't even close to being a viable mobile OS. You can use MultiROM to install and dual boot it so you can try it out very easily but trust me, you won't like it one bit.
Thanks for the info, anything I need to be aware of before I start having fun once I take hold of the tablet. I get the small one she gets the larger one, hahahaha. Happy wife happy life.
I keeping reading about the boatloader needing to be a certain version before going to the newest os? No?
And I will stay away from touch, since I am a purely linux guy for anything computer or laptop thought it would be worth asking.
Also, what's the deal with odin and tablets. I use it all the time for my phone.

The only caveat I can think of is to make sure you unlock your bootloader BEFORE you set up your device, as the unlocking process wipes everything.
I'd much rather have to deal with a smaller screen than an unhappy wife, you're making the right decision . And actually, I personally prefer smaller tablets as they are easier to manage and are better for gaming. With the exception of my Surface Pro 3, all my tablets are smaller sized. I have the 2013 Nexus 7, the iPad Mini Retina, and a Dell Venue 8 Pro which is an awesome 8" x86 Windows tablet that runs full Windows, not the dumb RT version.
I'm not the right guy to ask about the bootloader. I don't like Lollipop so all my Android devices are staying on KitKat. I haven't flashed any ROMs on the N7 in ages so I haven't done any research on bootloader compatibility. If you have a link to where you read about it, post it and I'll look into it for you.
Trust me, Ubuntu Touch is not worth your time. I flashed it on both my N5 and N7 just to mess around with it and promptly deleted it. It isn't worth the space it takes up on your device. It's that bad. But if you want to see for yourself, just install MultiROM, it has a built-in option to install Ubuntu Touch as a secondary ROM. You should install MultiROM anyway, as it gives you a painless method for trying out new ROMs without losing your current daily driver setup.
Odin is specifically for Samsung devices so it doesn't apply here. Familiarize yourself with ADB and fastboot, as that's how you'll be doing a lot of your mods.
When you say wipes the device, do you mean installed apps and date but nothing OS related right.
Since I don't do anything major with it (once I get it) and my wife didn't either I don't think wiping is an issue.

It just wipes all your user data, the OS is still there. It's basically a factory reset.
I followed instructions to root it and its rooted, but have never been able to get Cyanogenmod to Install (I always get the same error everyone else does), and when I try to check out different ROMS, no one even posts many pics to show what the difference will be to use that ROM.
My phone looks the same as before and I'm just using ADW launcher to set it up the way I want it to look.
So how can I tell exactly what point of rooting my phone has reached? Do I actually have a different ROM, etc? I don't know much about this stuff and I'm not bricking my phone messing around with it until I know exactly where to start.
What custom recovery and bootloader are currently loaded on the phone?

Hi!
Go to your phone's System Settings --> About phone.
In there, you should be able to figure out which Android version is currently installed on your phone; if you have a custom ROM, most of the time ROMs developers will also add an additional line somewhere on that screen to tell exactly what revision of their ROM is installed. If not, you may be able to grab some more information by checking your build number or your kernel revision.
If you tap a few times on where it says Android Version, under Settings>More>About Device , it usually does a little animation of the rom version. Im trying to decide on a rom so mine is kit kat 4.2.2 at the moment and dislpays an Android logo in the Kit Kat logo style.
Since the bootloader version is not displayed on the About Phone page, you will need to determine that with another method. A simple way would be with the Samsung Info app from the PlayStore, the one posted by vndnguyen.
I personally use Terminal Emulator commands to determine phone info.
Code:
getprop ro.bootloader
getprop | grep version.baseband
I got the app from the Play store and it shows I'm on 4.4.2, but that the Knox has been tripped (I know it's rooted because I have an app that verifies root), but other than that, I can't tell any difference from how it was originally.
Guess I just thought rooting it would make it look a lot different and after reading through all of the forums, there seems to be 100 steps just to try out one new ROM and I don't even know what you do if you get it and decide you don't even like it. I just don't want to brick my phone.

i was watching youtube videos of reviews of the different custom ROMs gave a good idea on the features and layout of each rom. I as well am having difficulty deciding on a ROM to flash as this is my first smart phone and am new to it. ive been reading and watching a bunch of tutorials but finding information on whats currently stable for our particular phone can be somewhat dated. i know moderators want to avoid a "best roms" thread but for those of us just starting out with a rooted phone it sure would be handy to have opinions on what ppl use for the SGH-I747 and why, so its easier to decide on one.
is it reccommended to upgrade or downgrade? in order to compare ROMs its watching a video for 15 min to see what features it had at the time the vid was made and reading the developer forums on each mod to see what bugs are present in the current release but its not all compiled anywhere. its that or randomly flash ROMs on there to test them out and risk making mistakes. its usually always better to have advice from those with expertise and perhaps avoid making commonly made mistakes. ive read a bunch of helpful and handy guides on here but doesnt seem any way to easily compare roms or get feedback on what users have decided on sticking with or anything additional specific to this phone that should be considered before flashing certain ROMs.

this thread may help to explain some badic things.
http://forum.xda-developers.com/showthread.php?t=2343223
my advice , for what its worth ...
1) READ READ READ
2) make a backup of your current setup so you have it to fall back on.
3) NEVER downgrade your bootloader , flash any ROM/kernel not meant for your device (sure way to brick it).
theres always risk when flashing anything , but the risks can be minimized by understanding what your doing , or rather the process.
as far as flashing roms , its pretty simple once you understand it (as with most things. lol). reading thru a ROMs thread will give a general idea of any features , issues that the users have. the OP , first post ; will tell you alot about the ROM/features.
good luck and happy flashing.!

The act of rooting does not outwardly change the look and feel of a ROM in any way. It's what you do after rooting that makes the difference.
Some like the Stock Rom of a device and/or do not want to lose some of its unique features. These people will root but not flash a custom ROM.
I've had two android phones and one tablet. Initially I root a new device but leave it on the stock ROM. At that time I will use an app that requires root to freeze any of the pre-installed apps that I don't use (My definition of bloat.) I don't remove/delete them at the beginning. If freezing them breaks some other functionality I want that app still on the device so that I can unfreeze it and make everything work again. Both of my phones have been Samsungs, a SGS Captivate and a SGS3. After a while on rooted stock I have changed to custom ROMs on each. The Captivate went from stock to CyanogenMod to a CM derived ROM. The SGS3 went from stock to a re-themed, custom ROM based on stock but with much removed (carrier bloat) and some other functions added. I expect to soon change to a later version of the same ROM with even more removed. Others want to have a ROM with every bell and whistle possible to have present. It's all individual preference.

There are so many variations on what is possible that a compilation thread to cover all situations would seem as huge as wikipedia. Your approach, reviewing videos and checking rom OPs, has merit but it also has limitations. Unfortunately some of the devs give you almost no information about the features and customizations of their ROMs. Others will simply state that they have made a change or two to some base, expecting you to be familiar with the base. Which means a lot of more reading/reviewing for a person new to customizing their phone.
To advise any one questioner on what can be installed on their phone a responder must first know what bootloader and modem is on the device, are you already rooted, do you have a custom recovery installed yet, are you willing to risk breaking your warranty; the list goes on. Then the hard part comes - they have to recommend something that is in the realm of what you are expecting, even if you do not know what you are expecting.

CWM 6.0.1.2 is a bit dated, their latest version is 6.0.4.7 and even it is a bit dated. You may find that to flash a current ROM you will need to update CWM. For some of the newer ROMs even 6.0.4.7 is not current enough. You will need to change to Philz Recovery, based on CWM, or TWRP. Bear in mind that if you change to TWRP you will not be able to use your CWM nandroid. I don't know if the same applies to Philz Recovery.

There is definitely a newer version of SuperSu (by Chainfire) available. It went through a lot of development to handle issues related to Knox that came out with Touchwiz 4.3. SuperSu is now up to 2.49 and I would recommend upgrading it no matter what ROM you should end up choosing. http://forum.xda-developers.com/showthread.php?t=1538053 There is a zip you can flash from you current CWM there.

Sasktel has released 4 versions of Android 4.4.2, each with a different bootloader and modem. Any should be fine no matter what ROM you choose, even a Lollipop based ROM. But to check you can get Phone Info - Samsung by vndnguyen from the Playstore. Or you could use a pair of commands in Terminal Emulator
Code:
getprop ro.bootloader
getprop | grep version.baseband

You could either go straight a Lollipop based ROM or start with a KitKat ROM. The KK ROM would probably be a bit more stable, although some of the nightly 5.1.1 LP ROMs are looking good according to many of the people installing the nightly versions. If you want something already customized with options for your choosing look to CM and its derivatives or one of the AOSP roms that are already tricked out. The other direction would be to install the most barebones AOSP ROM you could find and use XPosed with the GravityBox or Wanam module to tweak just about everything, but not both at the same time.
wow thanks that all helps a ton ill work on locating and updating all of that :]
Hello,
I've got a Galaxy Tab Pro 8.4 that I bought during the few months when it was the top of the line small tablet from Samsung (before the S series came out). Since it seems clear that Samsung has abandoned it and it won't get an Android update, I want to see what it'll take to upgrade to at least Lollipop. I'm pretty tech savy, but I've never tried to do anything like this with Android and I'm not at all sure where to start.
I've started to read the thread on rooting, but I quickly got a bit lost as I don't understand the terminology.
My goal would be to simply get to stock Lollipop or Marshmallow and have a stable, functional tablet that I don't have to tweak or mess with much. I'd also like to be able to go back if it proves too buggy. Is that feasible, or is rooting plus upgrading pretty much something that will require constant maintenance and tweaking? If it is possible, can someone point me to a how to for complete newbies?
Rooting will not help you upgrade your tablet to Lollipop or Marshmallow as they aren't available for your device. You might want to google "what is rooting" and find out what it does before proceeding.
The only thing you could do to get L or MM is install a custom ROM such as this:

What makes you thin that his device is not have any Third Party ROMs (i.e CyanogenMod)? FYI this is the Tab Pro Fourm, and his Device should damned well be able to get to Lollipop or Marshmallow. e.g. CM12.1, or CM13.
As for rooting which you have to do at the start. Will most likely send him back to SamFirmware's where he'll need to likely first downgrade his Firmware to one that has a rootable exploit. i.e. a 'BOC1' ROM for the T325. (Which is the version I have). Through Odin (Samsung's Android Firmware Windows PC flashing Software). Then run something like the CFRoot App to get root.
NOTE: THIS WILL THROW YOUR KNOX FLAG!
This means that you'll never be able to use Knox services on that Device ever again. It will also throw the Warranty Flag as well Alerting Samsung that the Firmware was tampered with. For the moment (As I gather there is no known way to reset either of these Flags.) Not that this should stop you from installing either CM12.1 Lollipop (Seems to have lost support to) CM13 Marshmallow which is currently on a nightly release.
So the better question to ask is which T32x does Op even have? The T320 (Wi-Fi) The most common, and cheapest version has the greatest support. Where as the T325 (LTE), and T321 (3G) versions seem to be leaving behind. though even these are currently well into Marshmallow, and like with most ROMs there are some small bugs. But, on the whole My Device is more or less working as it should be.

1) I read the OP. He said, "stock Lollipop or Marshmallow."
2) You don't have to root TouchWiz to install a custom ROM. All you have to do is install TWRP, but it doesn't matter because of #1 above.
Well yes if he wanted Stock then he'd be outta luck. But that is not how I read it. I read it that he has accepted the fact that Samsung have left us in the lurch concerning any future updates.
That's how I read it, so the question follows in how to install a Custom ROM. Granted it should be possible to install TWRP v. 3.0.1-0, though Odin, and then the Device appropriate ROM. It should go without saying that the T320, and T325 are not the same Device, even if they are both collectively known as Galaxy Tab Pro's 8.4. As such it would be upnto the owner to know which version he might need.

The problem, is folks really need to stop using the word "stock" as it really doesn't mean jack. Or at the least, means so many different things to different people, as to be basically meaningless. I would take stock to mean, what belongs on the device per the manufacturer, so that would be Kitkat TouchWiz in this case. To others (and probably what the OP is getting at) is a "pure" unskinned Google experience like Nexus. But seeing as Nexus is limited to such a small number of devices, I don't personally feel you can consider that "stock". CM is AOSP based, and at one time considered by many to be close to a pure AOSP experience. But those days are long gone, and there are so many proprietary CM features and apps now, you can't even begin to consider this "stock" by any means.

What you are asking for is CM12 or CM13 (LP or MM) or one of the CM based ROMs. Those are really your only choice when it comes to anything past KK on this device. The CM ROMs are are very stable at this point. You might run into an obscure bug, but to be honest, its less laggy and overall a much better experience than the official Samsung TouchWiz ROM. And if you want to be free of Samsung bloat, CM definitely does that as well.
Tweak or maintain? You don't have to do anything after flashing the ROM, if you don't want to. You can decide to update to newer nightly CM builds from time to time, but that is completely optional. And to be honest, even CM13 is so stable at this point, that the nightly updates don't really change much of anything.
Go back? That's a breeze. Just do a backup in TWRP custom recovery before flashing a ROM, and you can restore to that backup (basically a snapshot of your existing configuration).

Honestly, just searching and reading are your best friend. You'll learn a lot more that way, than folk spoon-feeding you the info. The process isn't really all that hard. There may be a lot of esoteric lingo, but you can easily Google or use the XDA site search to find out what those terms mean. And once you've gone through the process, you'll likely be happy for the learning experience.
XDA is a wealth of information, for those willing to take the time to learn and search. All the answers you want are here in one form or other. Difficult to wade through at first, I'll agree with that. But all of us here had to go through the same thing at one time or other.
Its really hard to help someone when they say is "I'm a newb, tell me how to do this". Make a lot more sense for you to just dive in, then come back here with some specific questions, which we will gladly answer.
it would help to know what version OS you're running and the build #.
I rooted my tablet late last year (bought it in May 2015). Wasn't hard to do after some reading. Knox is still good too...1 yr warranty will be over soon.
Thanks all, I appreciate it. I've been doing some more digging to try to learn what everything means so I might know what I'm talking about. I started with the Lifehacker rooting guide (I can't post links yet, add this to lifehacker dot com: /5789397/the-always-up-to-date-guide-to-rooting-any-android-phone) and their how to flash a ROM guide (/how-to-flash-a-rom-to-your-android-phone-30885281) as well. Let me know if those aren't good places to start. I've also read through the CyanogenMod how to for the 8.4, which seems pretty thorough.
I definitely appreciate the push to search and learn, but it can feel like drinking from a firehose. Most "how to" posts are written assuming the reader knows the terminology and every post I read means Googling a half a dozen terms to understand it. For example, I have no idea what the Knox flag is or why I'd care if it got triggered. I don't care about the warranty flag, I'm past the 1 year mark so it doesn't really matter, right?
When I said "stock" I was referring to stock out of the box Android, not stock Samsung. Stock Samsung means staying with KitKat which I'd rather not do. My phone is a Motorola Droid Turbo, which I think is pretty close to stock Android Lollipop, so that I'm familiar with that.
However, I think I'm seeing that going stock Android isn't necessarily possible, or rather, other ROMs are easier to come by. Cyanogenmod seems to be the most popular and sounds very stable, I'll likely try that.
So, I don't need to root in order to flash a new ROM. What's unclear is do I need to do anything special to make sure I can go back to the out of the box Samsung KK that I have now in case I really screw it up or just don't like it and want to go back? Will the process of installing Cyanogenmod wipe my device (apps, files, accounts, data, etc.?
Any other surprises that a guy who has never done this might want to know before going in?
Thanks again for your patience and help.
I forgot to mention, I've got the wifi model, T-320. It's running 4.4.2, build number KOT49H.T320UEU1AOC1.
Well you have a number of choices for your T320 (WiFi), Sadly nonmof those stock. Since Samsung has never seen fit to ever giving us one. For me the Samsung (e.g. Vender ROMs), were always the 'Stock' ROMs. 'Pure' ROMs (al-la Nexus), are clearly Custom ROMs.
The best, and quickest way to learn how to update from Stock to Custom would be to hit up YouTube for a few short Vids on the subject.

I've been doing some more digging to try to learn what everything means so I might know what I'm talking about. I started with the Lifehacker rooting guide (I can't post links yet, add this to lifehacker dot com: /5789397/the-always-up-to-date-guide-to-rooting-any-android-phone) and their how to flash a ROM guide (/how-to-flash-a-rom-to-your-android-phone-30885281) as well. Let me know if those aren't good places to start. I've also read through the CyanogenMod how to for the 8.4, which seems pretty thorough.

Those aren't bad general guides, to just introduce you to the basic concepts and terms. Just keep in mind that every different Android device has its nuances, which vary by manufacturer and over time (from one device to another - even from the same manufacturer). So you'll be referring back to Tab Pro 8.4 specific guides eventually.

Basically, if you don't know what the Knox flag is, then it probably doesn't matter.
The longer story, Knox is a enterprise mobile solution made by Samsung. If you company doesn't use Knox (and you don't use your device for work), you don't need it. The huge majority of folks will never need Knox or want it.
You're right, that if the warranty is expired, the warranty flag doesn't matter. And honestly, I rooted my device while it still had a valid warranty. I'd rather have a device that I can use how I wish, and install what software I want (especially if Samsung isn't going to support it with updates) and warranty is a secondary concern, at most.

Once you install TWRP custom recovery, you can make a backup of the current Samsung TouchWiz KK ROM; and revert to that if needed or desired.
But honestly, you won't want to go back. CM runs faster and smoother, with no Samsung bloat. You won't want to go back to the crappy TouchWiz ROM, that is 2 generations (Android versions) obsolete.
But it is a good idea to have a backup, in case flashing CM doesn't go right the first time, and the device won't boot.

You will absolute want to wipe user data when installing CM. Not doing so will likely cause major bugs and/or failure to boot. This is the general rule whenever flashing a new ROM. Although for similar ROMs (such as minor CM updates) you can try to keep user data. This is called a "dirty flash".
You can backup a lot of your data before flashing CM:
Apps: After root, you can use the app Titanium Backup (highly recommended) to backup apps and app data
Accounts: Titanium can backup a lot of this stuff, as well. Depends on what you are talking about, specifically.
Files: just move them to SD card or your computer. Or use a cloud solution (there are many)
You should always be backing up your data, anyway, if its important to you.

Same firmware as what I had prior to rooting it.
The cyanogen articles give a good rundown on how to install it. The only thing that I'm not sure about is whether getting the sdcard to be formatted/recognized is still an issue or not.
When last I checked back in Feb. it seemed like that was still unresolved. I have a 64gb card and getting it to be read by CM13 was absolutely critical. So any move to CM13 was postponed.
Running Kitkat is fine for me...after rooting it, I uninstalled/froze a lot of software incl. a lot of Samsung crap that was eating the battery. The battery is my only complaint with the tablet.

The SD card issue on CM13 was solved in early March. It was holding me back as well (stayed on CM12.1) , until I saw it was solved. Now I've been using CM13 for over a month. My 64GB card works great with CM13.

If you flash CM, you'll see its a lot smoother and snappier, especially on the home screens, app drawer, etc.
Thanks all, I plan on biting the bullet some time soon. Too much other stuff on my plate (like car repairs, etc.) so it'll have to wait for a bit. I'll check back in when I do. I'm looking forward to it.

Good to know on the sdcard thing...looks like I'll have to read up again on how to do.
Thanks for the note.

BTW, you can always restore your device to 100% stock (Samsung) by downloading the firmware from sammobile.com/firmwares and flashing it using Odin. If you get into trouble, this will help get you back out.
But since flashing CM13 nightlies is relatively easy, I don't think you'll have any serious trouble, just the normal learning curve.
I've had my SM-T320 on Cyanogenmod since the day after I bought it in 2014 and never looked back :good:

Cellular South is the US firmware for some reason.
I'm trying to load the latest CM 13.0 nightly this morning and running into issues.
I'm following the install instructions on the CM website and the loading of a custom recovery is failing at step 7. I get the start of the blue bar on my tablet, but I get this error in the command prompt:
Downloading device's PIT file...
ERROR: Failed to send request to end PIT file transfer!
ERROR: Failed to download PIT file!
Ending session...
ERROR: Failed to send end session packet!
Releasing device interface...
I've tried twice with the the factory cable and a third time with an alternate cable same result.
How do I fix that?
I should mention that I'm working on a Windows 10 computer.
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.
Hello everyone from Murcia!
First of all, sorry for my bad English. I hope you can understand me. I'll try my best.
I come from HTCMania.com to see if I can solve here some specific doubts I have, so I am able to replace the ROM soon.
As a good computer documentary (digital documentalist), I like to share my experiences from my humble contribution in appreciation for so many hours of work shared altruistically, when there is no advertising, at least initially, although sometimes I understand it.
There are times that because of lack of time I do not investigate more on this forum to find out about things, and here you can not always help to everyone or there is no luck to be replied.
I'm very afraid to damage my cell phone even though there are tutorials to unbrick it.
As you know, each one establishes his own goals of how far anyone wants to get complicated life in this world, some because they are good programming and therefore are developers, others are satisfied with less, but in different degrees of depth knowledge, so there are different groups. Well, I fit into the second group, but I would like to install the ROMs cleanly.
I'm not going to do a lot of experiments to the mobile, just the right ones, I know perfectly well where I can get in and where not, because in advanced configuration issues of kernel, CPU and battery I prefer not to go deep in changing codes (sometimes I have tested some tweaks to get more performance, but I am not interested in testing all I read, because although I know the logging tools and other tweaks, having studied the forum for years, I'm scared, although I dabble in Odin and several Samsung models and a Sony with two bricks and then other installations of simple ROMS without complicate too much my life.
Until then my introduction, I start by asking the questions:
1) Do you need to do wipes three times or when you are going to format?
2) I would like to know if it is worth with the current versions of Android to have the root if one is not clumsy, simply to be able to use some application that requires it or if it improves the consumption of the battery.
3) What root method is best today for the LG G3 D855?
4) Is it worth upgrading from Android 6 to 7 or not because it is not the latest version of ROM Stock? Does it work well if anyone have tried on some Custom ROM?
5) What is the difference between revision 30N and 30B of LG firmware for Android M. I suppose some security bugs are corrected, but referring to what? Is it referred only improvements in stability, battery consumption and performance without specifying more anyplace? Is it worth upgrading to 30N knowing that it does not have root, are those improvements so significant?
6) Do the MultiROM work well?
I think my questions are interesting, even if for many they are easy to answer. At least they seem very useful to me if you answer them and I will archive your answers so as not to forget and to consult them.
I ask those questions because I found it harder to find an answer to them in the forum or board. As soon as anyone respond and from the data they visualize in my profile, I will get to work, but first I need to be sure of those things.
Many will already know this, but I not, and many others will not either.
Thank you very much in advance.
Regards!
Pedro
Hi, I'm just gonna answer a few of your questions..
1) Why would you need to wipe 3 times? Once should be enough.
2)If you only need it for a few apps, sure, why not.
4) Depends on what you want. Camera is a bit better on stock ROM because of proprietary drivers. Not to say picture quality is bad on Nougat, you just don't have as many cool options to play with. Other than that, everything works on Nougat and it is much smoother than stock ROM. I recommend you XenonHD 7.1.2 and pair it with Gamma kernel v50 for best smoothness.
As for root, I used the most common method (Kingroot+TWRP installer) because I was going to install custom ROM right away anyway.
Additional note: I highly recommend you to do a thermal mod on your G3 as it will prolong its lifespan significantly and increase performance.
I think that it's only a popular belief, read in HTCMania.com more than once.
What about Magisk to root instead of Kingroot? Which is better?
Thanks!

I think you cant root G3 with Magisk. You can flash it later form recovery to use it as a root app but you need other methods for actually performing the rooting of the device. I do recommend Magisk, however. You can also use SuperSU but Magisk has some extra features that make it more appealing.
What a mess!, don't? It's probably best not to root, if you have to use more than one program in case you use Magisk, or do it only with Kingroot.
Besides, the problem could be safetynet.
And now I read this:
https://forum.xda-developers.com/android/general/kingroot-malware-adware-root-t3563090
Well, it's actually very simple to root. I don't recommend kingroot if you plan to use the stock ROM you used kingroot on. If you wanna be safe, backup everything you need, do a factory reset, don't add any of your accounts, just sideload kingroot and the twrp installer, do the process and wipe data again, now from TWRP. (hold power+vol down until LG logo, let go, then press again the same combination to enter recovery. select yes when asked to wipe data, it won't wipe but enter recovery)
If you want to replace the ROM, and your phone is currently on stock Marshmallow, just use Kingroot. It will be deleted when you change ROM so it wont matter anymore. I personally tested this method (https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268) and it worked flawlessly. Just make sure your model is D855 on Marshmallow.
