    each time i get stuck on step 11. I cannot boot into recovery. it simply boots.

  2. Adrian Mapes says:

    now it will not recognize the clockword mod recovery. it is simply the stock recovery

  3. I tried 3 times before reading on another forum that due to a change one should not auto – reboot in Odin. After cwm is installed, disconnect the phone from the pc, remove the battery. After that you can boot into cwm.

    now my phone is only showing with the start up screen.. etc “samsung galaxy sIII”
    need help please?
    my phone isnt switching back to normal :(

  6. Someone_01 says:
  7. Thanks it was a pretty easy tutorial to follow. I only faced one problem which you should state more specifically when putting your phone into download mode you have to hold the volume down button and also stae that you also hold down the power button and not just the home buttons. That wasn’t clarified that well cause it just says hold down the volume button & home buttons. So its “hold the volume down button, the home button, and the power button all together” til you get the warning message for all you that didn’t get that. I figured it out by quickly looking up a YouTube video on how to do it oncide I realized tht nothing was happening just by holding the volume and home button.

    Thanks though I now have my phone rooted!
