Advantages & Disadvantages of rooting [N00B FRIENDLY]

Rooting, I love rooting devices, till now, I have rooted countless devices, for others too..
rooting gives you the access to everything and you get SuperUser access.
Advantages
It gives you full access over your phone and enables you to fully customize it
You can block ads from apps
gives you access to root-only apps like Titanium backup & root explorer.
You use custom kernels that can improve performance and increase battery backup
you can overclock the processor to increase (for fast performance) or decrease (for better backup)
use custom ROMs (that I'm also making for GS2)
you get the latest version of android (last night i installed jellybean on S2)
Unlock additional features like WiFi and USB tethering
Upgrades baseband (it controls radio, improve signal & quality of your smartphone)
now here we come to disadvantages, whoa.... you'll be scared

It voids your warranty
Your phone may brick (however you can fix it if you have basic knowledge about ROMs, i fixed S2 too)
Security, viruses can enter (for explanation consider POST#2)
Source Code, android is open source and anyone can see the source code after rooting and it can be used for malicious purposes (refers to above point)
But don't worry, you can still Un-root it any time you want to
Hope you understood everything I said, still ping me back if you need to know anything else
Note: rooting process is different for every device.
Note2: I have written all I knew, pls let me know if I missed anyone

Getting root within Android does not guarantee the ability to flash custom kernels, radios, etc. Some devices have locked bootloaders, but can be rooted relatively easily (most Motorola devices).
Rooting isn't any more insecure than non-rooting as far as viruses go. If you have a Superuser app installed, any app that wants root will have to get your permission, so only allow apps you trust. This is somewhat similar to how any Linux distro operates and is part of the reason they are secure. Malicious apps that contain a root exploit would be dangerous even without root since the exploit can be done without superuser permissions.

What is Rooting?
“Rooting” your device means obtaining “superuser” rights and permissions to your Android’s software. With these elevated user privileges, you gain the ability to load custom software (ROM’s), install custom themes, increase performance, increase battery life, and the ability to install software that would otherwise cost extra money (ex: WiFi tethering). Rooting is essentially “hacking” your Android device. In the iPhone world, this would be the equivalent to “Jailbreaking” your phone.
Why is it called Rooting?
The term “root” comes from the Unix/Linux world and is used to describe a user who has “superuser” rights or permissions to all the files and programs in the software OS (Operating System). The root user, because they have “superuser” privileges, can essentially change or modify any of the software code on the device. You see, your phone manufacturer/carrier only gives you “guest” privileges when you purchase your device. They do this for good reason… they don’t want you getting into certain parts of the software on your phone and screwing it up beyond repair. It makes it much easier for them to manage and update the devices if they lock it all down. This way, all the users are running the same unmodified version of the phone’s software. This makes it much easier for them to support the devices. But, for the tech-savvy crowd, only having “guest” privileges on your device is pretty lame and it locks down a lot of potentially useful features.
What is BusyBox ?
When a phone is rooted, one of the most common things to do after rooting is the installation of the BusyBox binary, prior to running any applications that require root privileges.
To make sense of this, it is necessary to have a brief understanding of what BusyBox is. BusyBox is a collection of powerful command-line tools in a single binary executable that can be run for UNIX based systems, including Android. The collection of tools available depends on how the BusyBox binary was built, and the source code is GPLv2 open-source, available from BusyBox Website. Many of the tools don’t do anything useful without elevated root privileges as in a rooted Android device.
Many Android applications that require root privileges use BusyBox from the command-line extensively. Some of the utilities are powerful enough to severely alter your device, such as the ability to write data directly any partition on your device. Many third-party firmware packages including Cyanogenmod utilize BusyBox extensively and already come with prebuilt with it, so users should be aware of consequences if making any modifications to the existing installation of BusyBox, by themselves of from one of many pre-packaged Play Store applications.

What is Root?
Root is one process to unlock your android device by getting full access to your android or IOS Device.
Rooting is the process of allowing users of smartphones, tablets and other devices running the Android mobile operating system to all access of android or IOS devices. By Rooting attain privileged control over various Android subsystems. The root allows us to change the internal apps of our mobile. In a word, we can completely control the Android mobile itself by rooting. Root makes us Superuser of Android or IOS devices.
Is Root Safe?
Root gives you full control to manage your android device, and that power can be misused if you're not careful. Malware virus can access a lot of data on rooted phones if you can’t use it properly. Android's security model is limited to a certain extent so root access increases it. You need to be more and more careful to use it.
What is Root Permission?
Root permission is allows to access Android Operating System Code. It gives you access to modify Software code and install other apps that you normally don't get.
What is root in networking?
Alternatively, it can be called an admin, administrator, and gatekeeper, root is a superuser account on a computer or network and has complete control.
Is rooting illegal?
In some country rooting is illegal. Because Manufacturers don’t like to users root device and customize in their way. After root, Manufacturers lost her access to device. In USA root is illegal. BTW Tablet root is illegal.
Which app is best for Android Root?
I have ever seen Kingroot Apk is best for Android devices. It’s most useful to Root any android device. Kingroot popular to users because it’s easy to use. Kingroot can root any android device. Kingroot’s success rate is 90%.

Probably just a typo but rooting a phone is legal in the USA.

No,Impact if you see your battery is down you cn solve battery proble if you have rooted phone.

I'd like to ask something that may seem stupid, but can you unroot your phone if you installed a custom ROM and still have it working or will that not work?

In Linux, what Android is based on, the su (read: switch user) command is used to run a command as a different user, means the su command is used to run an OS function as a different user. It is the easiest way to switch or change to the administrative account in the current logged in session.
So using su to temporarily act as a root user - a root account is a master administrator account with full access and permissions in the system - allows you to bypass any default user-restrictions and perform different tasks with full permissions.
Because most Android versions by defaut use limited user accounts for normal use - making the system more secure - what restricts the user from running specific OS commands, the tool provided herewith adds su command to Android, what allows the currently logged in user to temporarily act as a root user - take note that a root account is a master administrator account with full access and permissions in the system.
su Command Syntax
To use the su command, enter it into a Windows command-line as follows:
Code:
adb shell "toybox su -c '[options] [username [arguments]]'"
Take note that if [username] is omitted su defaults to the superuser (in Linux term: root).

Hi, I came across this from another post where the user was trying to get su in his a022f. I have the same device and would like to achieve the same result. Unfortunately, I can't seem to find the zip file (there's no link to dl), or is it still being worked on, hence the absence of a link?

Do you start getting ads after rooting??

So i rooted a phone long time ago and i don't remmeber that after rooting you start getting ads on android, (i read this online ) mainly by apps like kingo root, king root ,etc, is it true?? So actually i want to root my phone again but i am not sure that will i get ads or not

On the homescreen or in certain apps only?

I read somewhere that
1. One-Click-Root
installs a proprietary superuser exploit. What does that mean? It means root control supplied by this app doesn’t work the same way as if you do your own custom root. The OneClickRoot app installs software that maintains a continuous connection to their servers, means
once rooted, the phone will stream you a continuous display of advertisements.
The ads are downloaded from that root-level server connection, and you cannot turn it off. If you had a standard superuser exploit, you would be able to fix the problem. But, with the OneClickRoot superuser, you can never remove the ads.
2. Kingo Root
like the app mentioned previously, nstalls a proprietary superuser exploit, too. Once again, this allows the app to maintain control over your device after rooting is complete, and that control is used to display ads.
It’s important to understand how invasive root-level ads are. They can disrupt any and every action you take on the phone.
Whenever the software chooses to hit you with another ad, it will, no matter what you’re doing. Because Kingo Root has ultimate control over the superuser exploit, you cannot remove it or the adware included in the package.
3. iRoot
like its competitors listed above, also installs a proprietary superuser exploit. Once again, this is a free app with a hidden cost. The root exploit designed by iRoot is used to bombard you with ads for the remainder of the phone’s life (unless you flash it). You cannot turn these ads off, and they are invasive.

Can you firewall block them?
OP, you can try blocking the ads like this:

@blackhawk
IDK. Never made use of such softwares.

@jwoegerbauer
@blackhawk
Thanks for answering,
I also knew about the apps you mentioned but never knew that they really show ads or not , and i haven't tried dns menthod you told after rooting, i rooted my device some years ago, with kingo root but i don't remmeber it displayed ads (maybe it did, or maybe i fixed it) that's why i wasn't sure, but is there any proper way i can root my phone , jwoegerbauer already answered my previous question and so you might remmeber , i dont have oem options and fastboot isnt working (tried all possible ways mentioned in that query)

To root a phone's Android it's NOT required to unlock its bootloader before.

@jwoegerbauer
Ya i answered it in my previous question too, that to install root without kingo root (and such apps) and with a genuine method i guess you have to install twrp and abd then super su right , or is there any other way?

Also booting into and/or flashing TWRP to root Android is NOT necessary. Rooting Android is to add SU binary to Android's filesystem ( preferredly to get stored in directory /data/local/tmp ), nothing else.
This can be achieved by means of ADB.
Doing so doesn't tangent any of Android's safety features as AVB, SElinux, etc.pp
