Rooting issues

[lordcenzin]

Hi all,
Hope anyone can help me to understand. I know many of you are "rooting" devices. My question is: which are security related issues? I know android is based on linux kernel. Rooting gives the user the root privileges and user remain administrator for ever (until it un-root device using other apps).

But is it safe to execute (after rooting) all application on the system as root? Are all android-*nix-like-advantages deleted?

I'm very insecure about permanent rooting! why isn't possible to temporary access to root privileges, as for pc, and after device maintenance become again "standard user"?

Sorry if question is stupid, please apologize me...i'm pretty newbie to android world.

Thanks in advance

I rooted my HTC, definitely worth it. no real security risks it can brick the phone though if you are not careful

When you root you will get an app automatically called 'Superuser'. With this app you can specify which apps are allowed root access. Only these apps can do the kind of dangerous administrator actions that could damage your phone. Other apps gain no extra permittions with root.

It is really a very safe way of doing things.

And as for temporary root, you can always unroot after by flashing the stock kernel, though this is rather pointless as Superuser will keep you safe.

thanks for you observations. I think that flashing again the device in order to return to the "standard status" it's not a good way to do this, but no worries, because it seems there are apps that do this in this application.

If rooting allows ONLY to certains application to have root privilegies, then I missed this point, and it quite safe, as you state!

Why devs didn't use a sudo-like approach or it is already that?

Thanks again for your clarifications

Don't know.... Does Odin work in Linux anyone?

I am currently rooting my Galaxy S2 and in SuperOneClick it appears to be frozen at "Running psneuter..."

Why?

Although I haven't used it myself, I understand that there is an alternative available namely Heimdall. This is available for Linux Mac OSX. I don't believe that it has all the functionality that Odin has, but you can use it to flash ROMs and kernels though.

You can find it here http://www.glassechidna.com.au/products/heimdall/.
