  1. Step 2) Hold the power button & volume down buttons together until you see the ‘fastboot’ screen. Then whatever you do, boot the phone up as normal anyway. Repeat until you get bored or decide this will never work and smash the phone. =]

    Seriously, WHATEVER I do, it boots up normally! As soon as I release that power button. I get the fastboot screen, and it says to move the volume keys to navigate etc, but as soon as I release ANY key, it boots normally. I thought, maybe I hold the power key and press volume, nope. Release power while holding volume, nope. Release all together, nope. Needless to say, as per EVERY effing guide I follow, things NEVER work for me!

  2. Hi, I’m wondering if you can help me as the option to unlock does not appear for me. When I type in the command prompt, another one pops up to say “waiting for any device”. I have tried looking up a solution but haven’t found one that works. Do you have any recommendations of what to do to solve this?
