    How to root .21

    I'm a noob when it comes to rooting and I finally decided I want to root so I can flash roms like gnufabio's that speed up your system. Conveniently I also updated to .21 before I decided this. Looking around I am finding things like Razorclaw don't work anymore. I did see some people saying I could root if I had B60 or below and I do. Is there a way to do this or do I have to wait till more exploits come out?

    Last thing: If I root and I have problems with my device (hardware problems not related to root) and I need to RMA, is it easy to remove the root so Asus will service it?

    And one more thing: What is the process exactly for a beginner to root and do the basic stuff? Is it root-> install CWM -> flash roms from there? Is there any tutorials on this or any insights?

    Thanks a lot.

    Yes, .21 is rootable now, doesn't seem to matter which revision of TF101.

    We were just discussing this in the thread below... http://www.transformerforums.com/for...ootable-3.html

    Go here for the guide: Wolf's ultimate flash and downgrade guide (NO ROOT NEEDED) (root opportunity for .21) - xda-developers

    I used Method 3, which flashes a CWM-based recovery first and then roots.

    OK...I have to ask a question...

    Why would anyone, especially a "noobie" want to root their tablet?

    This risk potential to mess up the tablet is significant, amplified more by doing it as a novice and also with the Ice Cream Sandwich firmware being updated pretty often these days.

    Just curious.

    The other thing, WHY do you want to root your tablet. Rooting most Android devices, the number 1 reason is to be able to do backups with Titanium Backup, and also to enable other things (tethering) that are blocked by the carrier.

    Since ASUS includes App Backup, and there are very few 3G tablets that have something blocked by the carrier.

    If you want to do something, be sure you know the risks. I rooted on HC to overclock (which was well worth it IMO) and to change the keyboard layout a bit. Now I am running a cornerstone ROM to allow me to run 3 apps at once.

    Please, do not root your tablet because it is what all of the cool nerds do.

    I am a nerd myself, and I have jailbroken iOS devices many times, am working on building android app, and consider myself to be quite good with tech. I said I am a noob at rooting just because I have never done it, but my main reasoning is a lot of custom roms that speed up the os and some of them also fixed a bunch of the problems I am having. Cornerstone was also another thing I was looking into. I have reasons why I want to root, this will be the first root for me on android though.

    I saw this but I was a bit worried by the first few words of the thread that it was experimental for unrooted devices and very risky. I have looked into RazerClaw or whatever the name is and it seemed a lot easier and less room to mess up.

    RazorClaw doesn't work with .21 firmware.

    Of course it is experimental, the method is only 1 week new. I myself read through about the first 100 posts in that thread before deciding whether it was safe or not. The only caveats (potential bricking!) seem to be Transformer Prime with unlocked bootloader can NOT use Method 2, and any Transformer Prime can NOT use method 3 at all. For original Transformer TF101, all reports I saw were successful.

    For least risk, look into Method 3, which does not require a firmware downgrade (in fact, it does not touch your ROM at all), so is actually safer, faster, and easier than Method 2 (which is downgrade to .17, then root, then upgrade to .21). It is also the thread author's recommended method.


    DISCLAIMER (for noobs):
    Following that guide is not as easy as "one-click" solutions. So if using ADB shell looks too hard, or if you've never used a UNIX shell before, or if you are just bad at following instructions carefully, then I DO NOT recommend you try this. I am not responsible, etc.

    @OP[NyanCat] You should pretty informed, so I think you'll be fine.

    I can confirm that Wolfs method 3 worked for me on a .21 B70 TF101.

    No problems at all ))

    Thanks for the reply guys. Couple of questions:

    1) Is the only file I need to download for the 3rd method the recoveryblob file? I see no mention in the third method of the blobs.

    2) After doing the third method(not to the rooting step) what has happened? Is my TF just downgraded at this point? How do I specify what FW to downgrade to if I dont download any firmware recovery blobs (question 1)

    3) On the third method under the rooting step it says "Select 'Install from zip file' and then select the file on desired location internal or external." What file do I select? What does it mean "on desired location"?

    Thanks a bunch guys.
