  • KK

    I have tried this a few times and get the same result. I have a Skyrocket running Gingerbread 2.3.6 and I am trying to root it via my Intel iMac. I can execute the Linux-Mac.sh just fine. However, it generates the following:

    I have the Disable USB debugging CHECKED. I have read that Macs don’t require the usb drivers to be installed and I have yet to find any evidence of there being USB drivers exclusively for Macs. Could 2.3.6 be the issue? Is there a fix out there anyone is aware of? Thanks!

    Has anyone with AT&T Samsung Galaxy SII SGH Skyrocket LTE i727 tries this with complete success?

    I followed a tutorial on xda-developers forum and think I soft-bricked my (now retired) US Cellular Samsung Galaxy S Mesmerize 2.3.5 stock. I only had it for one week.

    After I finished with Odin and all steps I rebooted and phone is stuck on Samsung logo with vibrate mode=once, 3x, once, 3x etc.
    I can hold the buttons down and get into red mode but nothing works, no files found.
    I would love to try to root again with my new Skyrocket but can’t afford another new phone if it doesn’t work.

    I’m going to post all my info for the new Skyrocket and if anyone out there has SAME phone with proper root using this method please let me knowif it does or doesn’t work. I will donate after successfully rooting.
    Model number:
    SAMSUNG-SGH-I727
    Android version:
    2.3.5
    Baseband version:
    I727UCKJ2
    Kernel version:
    2.6.35.11
    Build number:
    GINGERBREAD.UCKJ2
    When I first got the phone under Location and security I’ve checked Use secure credentials and I set a password for credential storage.
    Willl this affect the rooting process?
    I also put a password on the Factory data reset, will that affect the rooting process.

    Thanks to anyone and everyone that takes an interest and is willing to help. I obviously don’t understand the entire process but am reading, researching and learning.

    • Dynho

      I have a Skyrocket from AT&T and got the super user with this method. I believe that my phone is similar to yours. I’ve just finished the process and already installed an app that needs super user access. I’ll try to advise you if I get any problems, ok?

    The update locked my Skyrocket into a continual 30 second reboot loop of death. Safe mode didn’t work, nor did pulling the battery and SIM card.
