  1. I somehow found AOKP to be a little more stable than CM. Nevertheless a very nice post.

  3. Hi, first thank you for this tutorial
    I'm about to follow it but there is something that doesnt add up : you say we need to set up the SDK first but then you dont use it during the process (assuming we get into DL mode using phone softkeys)

    So can I just dispense with it or I need it for other things (drivers maybe?)

    I just want to make sure I'm not going to hard brick my phone again...

    thanks
    Ilan

    1. The 'adb' program is part of the Android SDK. You'll find it under android-sdk-linux/platform-tools/.

      Regarding bricking the device, read my disclaimer and here be dragons. :)
