  1. Hi this worked for me but exactly how do i use the triangle away,,,as you have guessed I am a complete newbie with tablets. do i use odin to install or opy it to external card and double click?????????
    thanks

  2. I have Baseband P3100DDCLK1; Build no: JZ054K.P3100DDCMC1; can it be rooted to P3100XXDLL2, JZ054K.P3100ZSDMC1? How do I do that?

  3. That was great!
    So fas this was the fastest and simplest way in rooting the tab under that firmware and baseband version.
    And Honestly,..this was the first time I ever did this. I am, in all honesty, a tech illiterate so to think that the only way I was able to get through this was the reading know-how and skill in following instructions this process was pretty accurate. 🙂

    I have some few questions though.
    First, Is the firmware and baseband specifically noted for this rooting is as is?
    Second, is the versions of the Odin used to root/flash the device that was noted to be downloaded on the site is the only one that I can use? cuz I’ve been seeing some different Odins elsewehere like Odin 1.87 and so on..
    Third, is the principle in rooting/flashing/updating firmwares/devices always the same?

    *sorry if I may be using some terms out in context. doesn’t really know the jargons.

    Anyway! Thanks! 😀
