    If you're thinking about rooting your phone (for whatever reason), there are several vital things you need to know. One of these is called the nandroid backup.

    A nandroid is your lifesaver... it takes a snapshot image of the device's entire current state, as it is right then, and saves it in a .zip file on your memory card or internal memory. I recommend all nandroid backups get saved to the external memory card, and copied to a PC or jump drive for safe keeping.

    Once you root and have a custom recovery installed, your FIRST action should be to backup the phone in its pristine, stock rooted state. Save that as your baseline backup. Make backups regularly: at least every two weeks if not weekly, and especially before installing a new ROM or changing ANYTHING in the /system partition.

    * -Let me say that again because it's IMPORTANT! Before you change ANYTHING in /system, STOP and make a nandroid backup in Recovery! It may be a trouble, but bricking your phone is even more trouble. -*

    Both ClockworkMod and TWRP Recoveries have Backup capability. These .zip files can eat up your memory card quickly because they're large. As long as you're copying them all to the PC, you need only keep three on your card: the original stock rooted backup, and your two most recent backups. If the last one is somehow corrupted, you can always restore the one just before that without losing everything.

    Want to ignore this advice because you're in a hurry? Here's what will happen.

    If you STILL decide to change something in /system and you don't have a backup, you will have forever altered how your phone works... and it might not work at all. You can't get that original file back: and no, a factory reset won't fix it (that only deletes the /data partition and does not touch /system) and you will have a broken phone on your hands with only a couple of possible solutions... and none of them are fast, cheap or easy.

    So save yourself from having to buy a new phone or sending yours to a distant repair facility for a costly re-flash to stock... make nandroid backups often. You can never have too many nandroids. You CAN have too few.

    If you have any questions about nandroid backups, just ask! We're all here to help you, and we'd much rather help you learn how to make nandroids than help you TRY to restore your bricked phone because no nandroid is available.

    For even more information on rooting (and you need to read & learn as much as you can before you start), read this great post:

    http://androidforums.com/threads/rooting-best-practices.450904/

    And remember: if you're unsure of what you're doing, STOP. Ask questions BEFORE you proceed! The last thing you want to have happen is to be in the middle of a system rewrite and your battery die on you while you're frantically asking questions. We're here to help you learn!

    :)

    I was thinking of rooting my tablet so I could use a mod for a game, is it worth the risk?

    Yes. As long as there's been plenty development for your device (root exploit, custom recovery)

    Hello there! im very new to this entire cell stuff, im what you could say I know just enough info to be dangerous to my cell lol.
    I have a SAMSUNG GALAXY NOTE II and just this past weekend I started seeing a message saying my phone isn't rooted or something like this. So can you please explain to me what is the ROOT and should my cell have it and if so where do I get it AND how does it work?
    Any help I welcomed and I read that I must back up my cell often once I root it if I root my cell

    Thank you very much
    Fran

    I've no idea why your phone is giving you that message but you certainly DON'T need root.
    Root just gives the user and root apps access to the system partition of the phone that is locked down to prevent people messing their phone up.
    Some of us like to tinker with the system so we root. When is the phone telling you this? Was it an app?

    Hi Fran and welcome to Android Forums!

    It sounds to me like you have installed an app that is designed for root access. It could be Titanium Backup or just about any other type of app that needs access to the phone's root operating system. If you're brand new with smartphones, you might consider uninstalling the app until you're more comfortable with the inner workings of your device. Once you've read a LOT, asked a LOT of questions and are confident in your way around, we can talk about rooting your phone.

    Rooting itself does NOT do anything to your phone: it's just a key that unlocks your protected files. That said: access to those files, as funkylogic said, is a powerful tool that can make or break your device. That's why the backup is so important... if you somehow mess things up, you can restore the backup and it'll be like nothing ever happened.

    I hope this helps. It's great to have you here! :)

    And I make sure before rooting that there is a way to return to stock,This is why I have not rooted my wife's HTC Desire 610.That I know of (return to stock).
    Now my G2 I had it rooted before Lollipop update and I install the stock firmware in December.So I've updated to Lollipop and still debating whether I want to re-root or not.

    Re your laptop: immediately go to malwarebytes.org to have your laptop cleaned. Do NOT go to malwarebytes.com. Do NOT download from anywhere else. MalwareBytes is the most effective program for removal of malware, consequently, the bad guys go to great extremes to prevent this software. I can not stress enough the importance of running malwarebytes.org. I do not have any association with malwarebytes.org, but i do have decades of experience.

    The only real way to remove malware,Is to reformat.
    Even with malwarebytes,It will still be on the hard drive embedded in the OS.

    On the Basic tab of Kies, does it show both a Current Version and an Installed version of the firmware?
    If yes, then if they are NOT the same, then first let Kies update your firmeare.

    After firmware is "current" according to Kies, then:
    Download from the Playstore and installl on your phone: Root Check Pro by JoeyKrim.
    Run Root Check Pro (there are many root checkers-Root Check Pro by JoeyKrim is my preference.
    Root Check Pro | select Verify Root | ypu will see "Root access is not properly installed or granted on this device".

    Now download from the PlayStore and install "SuperSU Pro" by Chainfire (once again this is my preference.
    Once again run Root Check Pro and you will see that SuperSU Pro by Chainfire is installed.

    Once again, out-of-pocket for a couple of hours after which I'll go over a coujple of settings on your phone.

    The nandroid restore will completely replace the boot, system, and data areas - anything after the backup in question is going to be lost.

    Make a nandroid backup after every update.

    Use Titanium Backup for your apps, make a nandroid backup in case the update goes wrong.

    You will need to update binaries in SuperSU. I think usually "Normal" works. Don't think,I have ever had to do it through TWRP. I assume you have recovery and Nandroid backup. It's been some time since I tinkered with S2 but I found the posts here very helpful
    Root - Samsung Galaxy S2 (International)
    Definitely worth reading through Ironass' rooting guide. It has some suggestions for custom ROMs to flash etc, just read through it carefully and make sure you understand before proceeding.
    For cusotm ROMs if that is what you are looking for take a look over here http://forum.xda-developers.com/galaxy-s2/#subForums
