[Q] [NOT ASKING FOR HOWTO] A query about CM and rooting. - Verizon Samsung Galaxy S III

Hello XDA.
For a while now I've been thinking about rooting and adding a custom ROM to my phone. It seems like fun and I'd like to get involved.
Recently (as in I have no idea) Cyanogenmod released a new update that doesn't require the user to root their phone in order to install CM. However rooting allows full administrative access which is something that I'd like to have. Does CM root in the process of installation or does CM by itself have enough capability and features so you don't require rooting at all? If not, do people still root their phones before installing CM?
For starters I'm running Android version 4.1.2, if that will help in anyway possible.

Could you post a link to the source saying you don't need root to install cm? You can't actually post a link because you're brand new, but post the url anyway.
CM in itself does not root the device. The process of rooting is simply granting administrative permission as you already mentioned. It has root managing applications (such as supersu) installed, and a lot of its built in features require root access. I can't think of any instance where you could install the rom without root permission because it needs to change specific files to run, such as the kernel and system partition. This by default can't be changed without rooting the device.
Rooting is very easy and has to be done first, then you have to unlock the bootloader, then you can install custom roms. As long as you aren't on the 4.3 update.

It's on the wiki under "/w/CyanogenMod_Installer"
Code:
Do I need to root my phone before installing?
No. You can have a rooted phone, or not. The installer doesn't care. However, to be in a supported configuration, you need to be running a stock ROM.

OK, so no, this will not work on our device. Specifically because we have a locked bootloader.
A lot of the coding in the cyanogenmod wiki is extremely confusing. Even doing something as simple as installing the rom written on that website looks very unnecessary to me. There are much easier ways to do it that don't involve such complicated processes, with such potential to brick a device.
I feel like a lot of the developers know how to use heimdall which can write to any device. Our device can use Odin though which is much more user friendly. When they write guides, they write for many devices, and they're unaware of simpler methods on each phone.
In a nutshell, I'd follow guides here on xda on how to root and install custom roms. Just make sure to follow the correct guides for your baseband and you should be good to go. Once you root and unlock the bootloader, you can install any custom rom you want simply by flashing in recovery.

[Q] Are there Android phones that can be rooted without flashing ROM or bootloader?

Hi all.
I am a programmer and I haven't Android phone yet but I am going to buy it.
My goal is get full access to all the phone's resources so I can test and install applications which might need admin rights (and also my self-made applications).
I have read many stories and tutorials about rooting but most of them involve flashing a custom ROM or flashing the bootloader. I know that messing up with a bootloader is always a bit risky.
So the question is -
is there any phone which allows to set and unset root permissions without reflashing the complete ROM firmware or even worse - the bootloader?
P.S. Please, do not suggest official Google Developer phones, I haven't seen them in my country...
Thanks in advance for any suggestions.
Weird ... was it so difficult question? Anyway, I hope some experienced modder will take a look on this question.
For now I found only that Samsung Galaxy is pretty simple to root, no obvious bootloader or ROM reflashing, just some mystical update.zip. But I have no idea - maybe this update.zip contains modified bootloader?
There is root software for many phones that doesn't require flashing a custom rom. flashing a bootloader is quite rare. Rooting basically involves installing busybox and sudo.
Go look up what phones you like and then read about what 1click root methods are available, if any.

Hm... and what about that S-OFF thing for HTC Desire phones? Doesn't setting S-OFF mean doing something with the bootloader?
Also according to SonyEricsson, to flash custom ROMs with root access, it is needed to unlock the bootloader:
unlockbootloader.sonyericsson.com
Most HTC phones come with a locked bootloader, so you have to make it S(ecurity)-Off.
All the galaxy S line phones are extemely easy to root, and hard to perm-brick.
If it has 2e recovery you can use an update.zip (it just copies superuser and stuff).
If you are on 2.2 then you need to use an exploit like z4root or super1click.
If you ever soft-brick get to download mode and odin flash stock. The only way to perm-brick is with a bad bootloader flash (only needed for ginger leaks, and flash stock).

CyanogenMOD changes root access

So apparently CyanogenMOD is no longer offering root access as a default option. Which doesn't make sense to me cause in order to flash a Custom ROM like CyanogenMOD you have to be rooted and being rooted means you have root/superuser access to your phone.....Here's the link the article I read on Engadget - http://phandroid.com/2012/03/16/root-access-no-longer-the-default-in-latest-version-of-cyanogenmod/

It's definitely an annoyance for me personally, and I can see newbie users getting confused as to why their root apps aren't working. It feels like more trouble than it's worth. The superuser prompt should really be more than enough warning, especially considering that practically every guide on rooting goes on a tangent about its perils.

So if you don't realize some random mod's settings are preventing you, you shouldn't be using root? Great.

CM grows up
The article says root is still available three different ways. It's just not the default any more. That's smart.
If you don't know what root is doing and everything that goes long with it then no one should not use it. Far to many people root their phone cause they think its cool and end up bricking their device with no warrenty because its rooted. I personally think its a good thing

Thread moved. Would advise you to read forum rules and post in correct section.
Failure to comply with forum rules will result in an infraction and/or ban depending on severity of rule break.
You don't necessarily have to be rooted to flash a custom ROM; all you need is ClockworkMod or some other non-stock recovery. I have a Motorola Triumph and all you have to do to install CWM is boot into download mode, connect to a computer via USB, and replace recovery.img. No root necessary.

That's right. A lot of people don't understand the difference between rooting and flashing custom ROMs. Root used to be required before to be able to flash a custom recovery to the recovery partition of the device. These days a lot of manufacturers have provided bootloader unlock methods by which you can directly unlock the bootloader and flash a custom recovery, and still keep your stock un-rooted ROM. Root isn't necessary. CM's goal is to reach more people who aren't that technologically experienced. A lot of people are afraid of the word 'root' as they think it can damage their device. There's a lot of FUD about it still. Moreover, a majority of phone users don't know or care about what root is, don't use any root apps, and just don't need it to be there on their phone lest they potentially mess up something without their knowledge. They will just tap the allow button without having a clue about which app is requesting root and for what. For users like these, custom ROMs with root are a problem. CM wants to be able to reach these people too by offering a safer, non-root version by default. Think about how many people are stuck with their crappy, skinned stock OS for the entire life of their phone, limited by their manufacturer's decisions for updates. All these people will have the option of running CM and getting a feel of AOSP, and get a lot more joy out of using their phones just like us advanced users, with just the same amount of safety (mainly against themselves) as their stock un-rooted ROM. That's the idea. Experienced users can always go to Developer Options in settings and enable root for apps and adb in a second. It makes absolutely no difference other than providing an option, and that is what's important. In JB 4.2 ROMs and CM 10.1, the Developer Options are even more hidden and inaccessible to normal users, so that combined with root access disabled by default provides a lot of additional security.

[A510] Root A510

Hi guys. Is it hard to root the A510. I don'twant to install a custom ROM, just get root access to run stuff like Chainfire and have a little more control over GPU/CPU performance.
How long will it take? Can some one post me directions or a link?
Thanks!
Is it so hard to look at the whopping 8 topics here?

To be honest, there's not much. Even them, I'm a noob at this stuff. So I would've thought a little more hand.
There is a rooting guide and a program that will root your tablet, all within these 8 threads...
Sent from my GT-N7000 using xda app-developers app
There are many discussions about this topic.
Ok wait. So once I root, can I then update OS OTA. Will root be broken?
Its not hard at all, and while you surf xda in general, notice that there is the website part of xda with many good articles about the rooting process and its pro's and cons.
Theres a risk with any tinkering under the hood, but the guides a mostly quite accurate at what to do and its requirements for the process, but you, and solely you are responsible for doing it.
Another detail you have to obey to a certain extend is the posting of requests for advices in general, is that you ask in the appropriate section, eg. Questions and Answers, and the other sub threads like accessories, developement, and so on.
But dont mind too much about your first initial misplaced questions, and the subsequent grunty answers, unless you do it repeatedly that is. We all started as noobs, but follow posting rules as your first lesson.
And for your last question; No, you cant be sure of anything working as it did before you rooted, and further, flashed CWM, removed stock apps, setting up tweaks and mods etc etc.
OTA's is often depending on stock recovery, so nope, root can be lost easily, or the OTA execution might not be successfull at all.

1. Rooting does not automatically give you the ability to control GPU/CPU
2. What from Chainfire do you want to install?
3. The above stuff is not "noobish", ie. if you want to do such things you really need to know what you are doing - so better first read a bit more about root
4. When you root, depending on the method you choose, be careful with any update and better, do not do any FOTA update. It might cause the root not to work after FOTA (on A510 you use an exploit to be able to root which may be fixed in newer releases), or even brick you device (see simoneser's update here)

Ok, another thing. Which is harder and longer process...root or flash custom ROM?
Also, if I root, is it possible to stay with stock ROM? All I want is root access. Or with rooting must I got custom?\
Additionally, whats the difference between root and bootloader unlock? If I want to use things like CHainfire and Titanium backup, is unlocking bootloader enough?
PS: I will really appreciate if I can get a link (I have been trying to find) where the whole root process for this specific device is shown. I saw the XDA thread but didnt understand much.

Root is entry level. It is usually more difficult to flash a custom ROM as you will also need an unlocked bootloader (which the A510 already has I think), and a custom recovery.
Root, in popular Windows terms, is simply getting administrator rights on your current PC.
Unlocking the bootloader, is like having the BIOS password as well.
If you need Chainfire and TB, bootloader unlocking will do nothing for you. You need root.
To get root, I believe A100's Mempodroid exploit works for the A510: http://forum.xda-developers.com/showpost.php?p=25036001&postcount=93

[Q] Couple of Skyrocket/rooting questions

Hello everyone, I'm new to the forums and looking to root my ATT Skyrocket. But first a problem I've been having with it regarding wifi. The ability to connect to and hold a strong wifi connection isn't working right now. Even within ten feet of a router I still have the weakest signal and I don't understand why when my iPhone has a full wifi signal from the same spot. Anyone else have this problem?
I did some research and discovered some people complaining that the bloatware app ATT Smart Wifi was messing up their connection. So I want to root to get rid of bloatware, block ads, etc.
I also would like to install Cyanogen 10 (jellybean) onto my phone running 4.0.4. Now this doesn't require rooting, correct? But I want to root beforehand so can I flash this afterwards or will it cancel the root?
Basically I'm wondering if there's a specific order to flashing after installing a CWM, and if I can root and have Cyanogen 10 at the same time (and how).
And I have checked these helpful threads:

if your going to put a custom rom on your phone its best to have root even though it is no required and you can run a custom rom with root. majority of the reason for custom roms is for permission access to enhance the phones capabilities. and first thing you need to is root after your rooted you can flash any custom ROM that is made for the SKYrocket and root permission will stay

its stated in the sticky, quote from sticky:
TO INSTALL CUSTOM ROMS ON STOCK PHONES YOU DO NOT NEED TO ROOT THE PHONE , ALL YOU NEED TODO IS INSTALL A CUSTOM RECOVERY VIA ODIN, THATS IT. SAMSUNG MADE THE SKYROCKET VERY EASY TO FLASH CUSTOM ROMS.
ROOT IS ONLY REQUIRED FOR STOCK PHONES TO REMOVE BLOATWARE AND/OR MODIFY SYSTEM FILES FOR STOCK FIRMWARE, IT IS NOT NEEDED FOR CUSTOM ROMS AS THEY ARE ALREADY PRE-ROOTED.
ON STOCK FIRMWARE YOU NEED TO USE ODIN TO INSTALL THE TAR.MD5 FILE(NOT THE ZIP FILE) OF A CUSTOM RECOVERY(CWM OR TWRP) - ITS THE FIRST AND FOREMOST THING YOU NEED TO DO TO YOUR SKYROCKET TO BE ABLE TO DO ANYTHING ELSE TO YOUR PHONE LIKE FLASHING ROMS AND ROOTING THE PHONE.
I REITERATE: YOU NEED TO INSTALL A CUSTOM RECOVERY BEFORE YOU CAN ROOT THE PHONE OR FLASH CUSTOM ROMS, YOU DO NOT NEED TO ROOT THE PHONE TO INSTALL CUSTOM ROMS.

i dont know how to make it any clearer, rooting is not needed to flash roms.
flash cwm or twrp, then flash roms
for flashing roms, read the post for the rom u want to flash

You can have root access after rooting.some apps like set cpu,screen recorder,root browser etc need to have root acess.you can also flash custom roms compatible for ur device after rooting. But if you do the procedure of rooting or flashing custom rom improperly,you may brick ur device. You can get it back by sending it to mobiletechvideos.com. you can remove system apps like chaton,samsung apps,samsung hub,all whare play etc after rooting.

Rooting your phone is a must if you really want to get the most out of your phone.... Below are some of the benefits of Rooting your phone:
- You can have full Control over your phone... You can customize your phone to your heart's desire without any limits...
- You can Back Up And Restore your entire device
- You can debloat your phone (i.e remove unnecessary system apps)
- You can run Custom ROMs and Custom Kernels and other tweaks and scripts to improve your phone's battery life and performance
- Run useful apps which requires Root access
The only disadvantage of rooting is that it will void your warranty.. nothing more than that.. If this is the first time you are rooting your device then follow all the instructions properly so that nothing "unexpected" happens... And yeah, after rooting your phone always be sure of what you are installing and flashing because if you flash something wrong or a file for another phone then it might have a chance to brick your phone... so just be sure of what you are doing and look for other users' reviews before trying out anything new...
If you ever want to unroot your phone then simply flash your stock firmware OR use SuperSU's "full unroot and uninstall" feature...
Hope all these helps :highfive:

In addition to the above information I feel the need to break down "rooting".
As when people say "Root your device" they mean 1 or more things.
Root is the SuperUser (su) of the operating system.
Gaining root allows you to do many things, however further things of rooting...
Root (gaining the super user privileges)
Unlocking your boot-loader (to allow flashing custom recovery ROM which in-turn makes it easier to flash custom ROM's to your device).
S-OFF - S for Security (allows you to flash deeper hardware level firmware to your device.)
You can gain root (depending on your device) with the stock ROM.
You can unlock your bootloader without gaining root, just as you can flash a custom ROM which does not make you gain super user privileges (root)
You can gain S-OFF, and gain S-ON without rooting or unlocking the boot loader (depending on your device).
Some do all 3, Some do only 1 of the above, Some Unlock the boot-loader, to install a custom rom which has root, but don't S-OFF.
See further guides for more information on all of the above.
