I see everyone talking about rooting. What is it about?
Do I have to do it?
Will it improve my cellphone?
Will it change my imei ? (my phonecarrier is really strict about messing with phones and they block them)
Rooting gives you acces to the root of your internal storagfe.. For example you have an sdcard and you can only access a certain folder.. U have to 'root' it to get to the root of the SDcard. Some apps need this to work for example apps that can change CPU behavior etc. If you dont need it dont root

when u become root does it have like a new gui or its just the same layout?
the same layout but with a lot of customization options
dont think of ROOT as a thing....its a level of permissions. ROOT = GOD in unix/linux worlds (which android is part of).
http://en.wikipedia.org/wiki/Superuser
Another way to explain it might be....
User Level & Description
User = Normal, default user account (standard on computers and phones)
Power User = Elevated priveledges, able to do advanced tasks but not system wide changes (pc based more than phone)
Root = Top level access, can perform system wide changes and delete/modify what ever is desired
gaining root access allows you to do a lot of things that are restricted to a normal user.
root is the only user account with permission to modify the root directory of a unix/linux based system

so are the customization options in root command line or GUI?
and isit risky?

it can be both cmd or gui......in your phone once you have rooted it you will have a superuser permissions box popup asking for an application to be allowed to run in root mode.
yes, it is risky but the main benefit of android is if you stuff it you can flash it back to original spec again using the SEUS. Dont let the fact that its risky put you off, just make sure you have everything backed up before you make and changes
root your phone, install titanium backup and backup any apps that you want - then go play
(im offline now, but there are many other that can help - just read heaps and search is your friend)

k just rooted but nothing seems different...how do you even know whether its rooted?
o okay found a superuser app but can someone tell me what i can do with it? im abit lost
I suspect that rooting might not be a good thing, for you, my friend..

+1! I suggest you take the time to do some reading up.
Hello XDA-Forum users,
I ask you a question: How does Android Root works ?
I mean, for example, How does it works in Nexus One ?
This would be an understanding question to know more about how I get root from my Phone (Nexus One, for example) from scratch, from sources.
upupupupupup
Rooting basics:
http://lifehacker.com/5342237/five-great-reasons-to-root-your-android-phone
For details on how to do it on your device, Google or use the forum search. Lots of rooting information that is device dependent out there.
It basically gives your phone permission to do almost anything. It is similar to giving a user in Windows Administrator rights. It is called super user. You can do many things such as removing unwanted apps and overclocking.
This is not what I mean, I asks for an explaining in which the question is "How the root is possible? What active the root ?" Probably a kernel exploit, or stuff like that, to understand the underground passage to take it, from an hack view.
So, How works a root utility (such SuperOneClick) to set gid to 0 ?
Valid question, I am also interested in learning this.
In other words, if I were to perform the rooting manually, where can I find such info?
And some of the question is why su must be in some diredctories, and can't be run from /data/local/tmp for example?
Someone can enlighten us?

The general approach is taking advantage of bugs in the android OS
The process works something like this
User crafts some special data that contains a "payload" (the script/executable that we want to run)
User runs a system process that has root privileges and gets it to open the special data
The bug causes the system process to get confused by the data, and ends up running the embedded script
The embedded script runs with the same privileges as the system process, and thus can stuff that normal users aren't allowed to do (e.g. installs the SU app)
Commonly, things such as buffer overflows are used
So after gaining root access, which apps can run as root?
Or the user becomes root(as in desktop), and can run all types of apps?
Can root app(run as root) access everything?? Or app permission still applies?
Is it that system exploit is always used to run root apps?
can someone explain in technical details? not how to root.
are rooting programs open source??

Hi guys!
I have the same question and after searching and asking find this!
it is good!!
hope it works!

also look at the suggestedpages at the right of this page!
Hi, I would like to have root access to my phone, but not necessarily with a custom ROM. I would also prefer to not change my bootloader.
What exactly is rooting? Is it replacing the whole system image with an image that gives the user root access? Or is it just like enabling sudo for the user? Or is a smaller part replaced? (I am somewhat familiar with electronics, computers and Linux, but I find the Android hacking a bit confusing )
Also, is it possible to run stock Android, only with root access? Will the access be lost when upgrading?

What exactly is rooting?
root is the user account in Linux with all privileges. The root user can edit anything on the system. For safety reasons, users do not have all those privileges. When you root your phone, you will gain write access to areas of the phone you couldn't previously access and are allowed to run more commands in the terminal. Because applications do not get a lot of privileges, some of them require you to root the device in order for them to function properly (or fully).
Also, is it possible to run stock Android, only with root access?
Yes and Yes lost root on upgrade usually .

Thank you. How is the rooting performed? Is only an ACL modified, or is a more fundamental part of the system changed (like the kernel, bootloader etc)?
I know that a custom ROM might be unstable/experimental, but does the same apply for rooting, or is the modification so small that one could expect the exact same stability as in the stock ROM?

All your questions are explained in detail in the Development section
Sorry, I did not find it. However, I read this without getting smarter. This video suggests that rooting is a process that does something with your phone without replacing everything. An exact list of what the rooting tools do would be perfect
Not all tools do the same thing. To get a specific answer, you will have to ask the person that came up with whatever rooting tool you are referring to. Some phones take more to root than others.
Cache cleaners need root access to do their thing. Any way to slip something in the stock (settings, I think) apk when it makes the call for /system access? I follow the "progress" threads, but it's like reading a foreign language to me for the most part. I appreciate the work the devs do, just throwing out a layman's idea trying to help the cause.

essentially the way htc has locked down this phone is two fold. one, no root access. two, no write access to the internal /system partition.
the fr3vo root exploit allows us root access, but does not allow us write access to the internal memory.
currently, the issue of obtaining root access has been resolved by fr3vo, but the issue of gaining write access to the internal memory has not been resolved as is a bit more complex.
on a side note, to follow some of the logic behind your suggestion:
in order to modify any apk on /system, we would need write access to /system. in some android phones, like many samsung models, there is no write protection lock on the device. once you're able to obtain root access, you can remount /system as read-write and write away as you please. unfortunately, this htc device has been locked down through a write protection mechanism over the internal memory which prevents even root users from writing to /system. running an .apk with system permissions, would essentially be a similar form to having root access through the shell as fr3vo currently grants us.
hope that makes more sense than the foreign language the progress threads appear as!
alright so i know what rooting is , my understanding is that before rooting i won't have administrative access to parts of the file system i think that means that
i'll only have access to "/mnt/sdcard" and not to "/"
after rooting i'll have full access to the entire filesystem
i know why manufacutures dont want people playing around in there ,my understanding - many things break easily deleting something or changing some permison can "f" it up
i've been with android for 1 year and roughly 6 months ,been through an x10 a DHD
other various devices currently on the Mopho so im not a complete nub
i know how to root ,you install this ,push this ,do this , that etc
my question is how is the root part blocked and how is root acheived i dont mean how to root a certain device, i mean how do the exploits do what do they change ?

Basically, the root section is blocked since it is set to r/o which normal user permissions cannot change. Rooting exploits change the system permissions and pushes the su binary in to give you superuser access which will then allow you full access to the system.

as far as I know, Stock rom's don't have a root function implemented at all.
to get root access, people use exploits to change permissions of the folders to gain access to the System partition, and then the SU (superuser) binaries are put into /system/xbin , and then install the superuser.apk (to make use of the su binary)
EDIT:
Damn ninjas
so rooting is basically changing a few permisions of folders that i wont normally have access to in order to put the SU binary into the fore mentioned path
just re itarating to make sure i understand
additionally if i won't normally have access to these folders then how do they change the permissions <-- maybe pushing it but ask an you shall receive

You could say it like that but it grants you far more access and unlocks many possibilities making you the superuser. Rooting uses exploits which bypass these set permissions.
