    I have a Nexus S 4G 2.3.4 update. Will this method work on that?

    Adam7 years, 2 months ago

    I like your tutorials – very complete.

    Question: My Nexus S is 2.3.3 with the following:
    Baseband: M200KRKB3
    Build: GRI54

    Which method can I use to just root it? I do not need the ability to
    install any custom ROM at the moment.

    Can this method be used for Nexus One as well?

    Having a nightmare of a time trying to download the GRI40 link from the post above… get a “download” button, and then click on it, and it spins for a while, and then goes back to the download link. Kinda frustrating. Anyone know where else the zip file can be gotten from?

      i’m stuck in “waiting for device”

        Wolverine7 years, 4 months ago

        Dude, make sure your bootloader is unlocked.

          Yosua7 years, 4 months ago

          yes it is unlocked, i already unlocked it.

          lock state = unlocked.
