I want to distribute a few Nexus 7s for pure educational purpose. I Want a ROM in which it is not possible to install an app without admin's consent (a password, maybe?). I have flashed CM10 W/O Gapps,hence no question of Play store, and sideloaded a few customized apps, but the user can still install apps on his own by simply copying the apk onto the storage. Also, i want it to be flash proof, as well as unrootable( is it even possible??). I and also is there any recovery that requires a password before flashing any zip?

So, I'm new to the Android family and I'm curious about the Super User Account. I have no desire to root and install custom mods, I just want the ability to remove all the bloat ware associated with the phone.
My understanding is that I will need to unlock the boot loader, and then install "something" to create the Super User account.

In order to remove bloat, your device will need to be rooted.
Depending on your device, you may need to unlock the bootloader. Otherwise, you'll just need to root. Superuser is a root management app which allows you to grant other apps root access (or deny).
IMO the best application to remove bloatware (after rooting your phone) is Link2SD
I use titanium to remove bloatware, it gives you the option to freeze the apps first in case you remove the wrong apps. Once frozen if everything is still ok then it's safe to remove

Thank you all for your comments and suggestions...I'll look into all of them...busy reading all the threads now...whew!!!
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

Every time I flash a new ROM on my phone, whether it was my old Galaxy S2 or my current Galaxy S4, Google Play recognizes that it is the same device as before and installs all the apps I previously installed on the phone.
My android stick computer (Minix Neo X5) does not behave this way. Every time I flash a new ROM, regardless of whether it is an official ROM from the developer (Minix) or a custom ROM with CWM, Google Play does not recognize that it is the same device as before and I have to go through the arduous process of installing all previous apps.
Is there a file or folder that I could backup on my stick computer and restore after flashing that will let Google Play recognize it properly? build.prop?

Try Titanium Backup or Nandroid Manager (both available on the Play Store). They can change the Android device id to match the previous, there are also dedicated apps if you google "change android device id".

Thanks for the post. I was wondering what I could search on Google to potentially find my answer.
I will try out these methods and report back. I was unaware that Titanium/NAND backs up the device information (I thought it was just for apps and app data)
I am unable to get root currently on my Fire HD 6 running os 5.1.1, so I can't use freedom to bypass iap and license checks. I do however have a rooted collpad with freedom installed. I know there are apps out there that will let me move apps from one Android device to another via wifi. So my question is, if I were to install an app on my phone then run it through freedom and transfer the cracked/patched app to my kindle using some kind of sync app, would it work? And if it did, would the app remain patched once it was transferred or would it revert back to original? Kind of a pain of a workaround, but at least it will get me through until a root method is found for my device and os. So would something like this work, or am I just grasping at straws?
Point of this post(boring stuff )
In your stock ROMs you are pretty much stuck with the preloaded craps unless you root your device. Now you might not want to root your device for various reasons. For instance, almost all banking apps do not work on rooted devices. A way to tackle this is to use systemless root access provider like magisk. But unfortunately magisk requires Android 5.0+. So we need some other ways for our devices running Android 4.4.4 right? Well, fortunately there is a very simple method for debloating any stock ROM(I personally tested this method on Lenovo A6000 PLus but this should work on any ROM out there).
Note: You need a custom recovery for this to work, which can cause serious harm to your device if you do things incorrectly. You are also tweaking your device's system partition, so you might void your warranty. If anything happens to your device, its your responsibility.
Let's get started
Step 1: Download the "pico" gapps package from opengapps.org. For Lenovo A6000/Plus running stock kitkat, select arm,4.4,pico.
Step 2: Open twrp recovery.
Step 3: Install the pico gapps package that you just downloaded.
Step 4: Reboot your device. Now you will find that most of the google apps have a green icon with android logo(if you are using lenovo launcher). Just remove those apps.
Done
So, Which apps are removed?
Pretty much every apps are removed except Google Play Services, Play Store, Gboard and Play Newsstand. You can disable Newsstand and the security app(which does nothing but eat up space and resources) if you like.

Dude, 1st thing, you said this method needs a custom recovery which means you have to root the device at first or lest consider you just boot twrp using fastboot
And flashing gapps will remove the obselet gapps, and it won't remove the other oem bloatware present so actually this can't br called "Debloating"
Debloating doesn't mean removing gapps, debloating is the removal of useless or apps which can be downloaded from play store, included in the ROMs

Yes you have to use fastboot method but you don't need root access for that and as for the "bloatware" you are referring to, it's any unnecessary app that comes pre-installed with a device which you can't uninstall. Keeping aside the gapps there are only 2-3 apps that fall into that category, which you can just disable as I mentioned. In a device with 8gb or 16gb internal storage every bit of free storage counts. At least it's better than being stuck with all the apps in the first place.
