Hi ppl I am running custom Rom unlocked bootloader but all apps that require root are telling me root required anyone know why

You need to have superuser and busybox installed. You can get both off the market.

A common misconceptions it that unlocked=rooted. This is not true. Once the device is unlocked, root access has to be properly configured. The majority of custom ROMs properly configure root access but I'm sure some don't or there are bugs/issues with a few.
Personally, I prefer to troubleshoot root permissions issues at the lower level where I can view the specific permissions.
The easiest way in my opinion, biased of course, is to use my application, Root Checker Pro. I provide a free link to it off XDA (99 cents in the Market...).
If you could post the results up, it'll show which files have the correct/incorrect permissons and allow us to more specifically resolve the issue.
Some general approaches would be to reload Superuser apk from the market, uninstall/reinstall Superuser apk from Android/Market or install the Superuser apk file through a .zip from the custom recovery.
These method should do a mass reset/reconfigure on the permissions and resolve the majority of issues.
Hope that helps!

Is there a way to install an apk as a system app? I want to 'unroot' a device but still run an app that requires root access. I'm unsure of how this can be done, any advise would be very much appreciated!
Thanks
I know that the Z4 root app has an option for temp root functions which goes back to an unrooted state once you reboot.
My guess is that you can run that, place your apk in the appropriate system folder, install the apk from there & then reboot.
But again I'm not to sure if temp root functions work on our G-Tabs & if it does if it's as simple as I explained. Worth a try I guess.
Again I'm assuming that your not already in a permanent root state. If so then you'll have to unroot completely first & then try what I mentioned above.
Unless someone has an easier method?

Titanium Backup Pro (paid version 3.8.1 and higher) has a function that allows one to convert user apps-->system apps (as well as system app-->user app ... though this sometimes causes initial FCs, which generally disappear with reboot).
Not sure if the effect will remain after unrooting.
Just to clear up a bit, not because an app its on /system it will have root access. If you want to run an app that needs root, you need root, thats it. You cant unroot and use the app after that.
So, no you cant do that. Its 2 different things installing an app on /system than having root for an app.

So then how do proprietary apps like Sprint Nascar (as an example) run on an unrooted phone?
Why would Sprint Nascar need root permision?

It probably doesn't or it might I have no idea. The op never pointed out which apps he wants to use.
However & this is a big however, as I have no idea which apps require root access, one has to assume that any of the preinstalled apps that come on our G-Tabs do in fact need root access, yet they can run on an unrooted device. Again I could be wrong.
That being said, how does one go about determining which apps require root access?
Thanks for the replies guys. The issue is supporting proxy servers on unrooted devices. There are several proxy apps that require root access as well as a kernel that supports proxy. If the proxy app were installed as a system app, would this have enough rights to access the kernel as required? I don't know enough about this but was led to believe this might work if it was running as system. Same for apps that use CIFS, like mount manager. I guess I'll give it a try and see what happens...!
Like I said, being installed on System doesnt have anything to do with having root or not.
Im 95% sure about what I am saying.
edit: I confirmed it..so 100% sure, if the app needs root, you will need root no matter where the app is installed.
I'm aware what rooting is and I'm benefiting from it on daily basis on my GT-I9100. However, what exactly happens during the rooting process? As I understand, (often) custom recovery(for example Clockworkmod recovery) is installed, an application for managing programs which might need root access(for example SuperSU) is installed, su utility for switching to root user is installed, but what else happens? Are there some file permissions changed during the rooting process?
All I know is I had to install supersu from playstore after rooting and then downloaded rom manager to get clockworkmod but idea I got was the rooting itself strips security from phone so that you can gain full access that samsung otherwise blocked. I havent looked in depth to see anything that the root itself installed but hey im a newbie with this sort of stuff

You can install all these great programs from the Play Store that require root, also you have manual access (through file explorer) to your system files like frameworks, stock sounds, built-in apps and more. You can disable the annoying ads in the games, you can backup your app data (like progress in games, so you don't have to start over and over again), you can backup settings, change the system look (icons, sounds etc.) and much more. Otherwise you won't see any interface changes or unlock some hidden options. :laugh: Everything is done through the programs.
^The guy knows what you can do with root, he's asking what the details of the rooting process are.
I don't know either but I think you basically unlock the boot loader, then install SU.

At a high level the following changes (and a few more I cant think of) are made to the device:
Access to previously read-only areas of memory are changed to read-write
A binary called busybox is pushed to the handset (the location varies depending on rooting method used)
Busybox is a set to linux like tools compiled spercifically for the CPU of the device (usually ARM)
The SuperUser or other 'Gate Keeper' application is installed to allow and monitor access to the busybox binary (this is optional but is normally done by default and is required for most root apps to function.)
In essence, your original post is almost spot on.
Well, hello. I'm most certainly a noob, although I do have experience with developing for android and using Linux on a PC system. I haven't done any rooting/unrooting/custom-firmware-flashing before, however.
I believe this question to be about Android devices in general and so I'm posting it here instead of a device-specific forum.
The short version of my question is:
Is it possible to install a custom firmware on my phone, but prevent apps installed in it from having root access?
The long version:
Having read about how the Android OS works, I understand that each app installed in a system basically has its own user account, and that's how privileges work: The OS simply doesn't allow this specific user/app to access other apps or hardware.
Unless I'm mistaken, rooting a phone makes all apps run under the same user account: root. Which means that all apps have access to every other app and all hardware on the device.
I found many web pages that explained that this is a security risk as malicious code could then use anything at all on the phone. This makes sense of course, that's why most applications on a Linux system don't run as root.
I understand why rooting the device is necessary to install a custom firmware on it, but what I haven't understood is why the device has to stay rooted afterwards. Isn't installing a custom firmware basically replacing the OS on the device? If so, couldn't I replace it with an OS that doesn't run everything as root but instead runs every app as its own user, like unrooted devices do?
I've searched this website and others for information on this but I haven't been able to find something that answers this question.
I found explanations for why unrooting is needed to install a custom firmware, but they didn't include why the resulting system can't be rooted.
I found guides on how to restore the original firmware on a device, which isn't what I'm looking for, although this process is called "unrooting" (the word seems to be misused here, but maybe that's just me).
I also found guides on how to trick certain applications, which won't run on a rooted device, into thinking that the device isn't rooted. However, the reason I'd prefer my device not to be rooted isn't to trick any applications but for security reasons.
What I'd basically like to do, is install custom firmware but, once that's done, ensure that applications I download from the Market or install directly don't have any more privileges than they've been developed to ask for. Is that not possible? I don't understand why not...
Gaining root access to your phone will not give a single app root privileges, for the most part you will use an app called superuser or supersu to allow or deny any app root access. (Sometimes baked into ROM)
But you have no worries, any app that you download from the market will not have root unless you give it

Is that so? Thanks. It seems I was wrong at the very beginning of my logical process.
So, if I understand correctly, the lack of security isn't that anything installed has root access, but that it can have root access. Is that right?
Correct, even whatever custom ROM you are running has a built in app for lets say messaging, this will not have root access.
You just bow have the ability to do anything (mostly) to your device, but you don't have to

Look man, superuser is ROOT. Either your phone is rooted or it is not. A rooted phone can run apps that require it like ClockworkMod ROM Manager, Titanium Backup, Greenify, Wireless Tether for Root Users, File managers like Root Explorer or ES File Manager if you want to be able to access the system areas of the phone. So far as I know, there is no "SuperUser of ClockworkMod". If your phone is rooted (You will see superuser or "Super SU" in your app drawer. Here is a free app from the playstore that will tell you if your phone is rooted or not.
Root Checker
Install it and use it to see if your phone is still rooted or if you lost root somehow. If you still have root, then when CWM starts, it will ask for root privileges and the first time it asks, you will be prompted to grant it, once, for a certain time period, or forever. For stuff like CWM, root file managers, and Titanium Backup, you always grant root forever and you will not be asked again until the app updates and requires you to okay granting root privileged or not, then you grand forever and leave it alone.
If you find out you do not have root or lost your root, then you have to root the phone and the procedure is different for different devices, versions, and ROMS. For that kind of help, you have to search for rooting <your particular device and android version number>

Thanks for answer, well I thinked that too, because my phone cant use root privileges if the aplication superuser isnt installed, however with te superuser aplication my phone have root privileges but with the previous version, with actual version my phond dont have root, even the people in google play say the same "with the new version my phone losed root" and similars comments...
maybe the root version (clockWorkMod) work in this way and need the app for work.
maybe this one??? http://d-h.st/l91

I don't think so. You need to root it again, if your device is unrooted currently.

No, root access is global. You can however use Superuser or SuperSU to restrict root access to only one app, if you want.
Out of curiosity, why do you wish to unroot, yet retain root access with one specific app? What exactly are you trying to do? If you want to unroot because a certain application (such as banking/payment software) won't work if your phone is rooted, you can install the Xposed framework and use RootCloak on a per-app basis to trick the app into thinking you're not rooted.
Thanks you,:good:

This is good idea,
But i supposed (in Linux) if an App has Root access (777 permission) and Root Owner, the App is able to do any thing!
so what is wrong? what is different if an app has (root permission/root owner) or not?
