Xperia Z3 won't boot to recovery; boots normally instead

Hi,

So I recently rooted my device using this guide and updated to lollipop using the links inside. However, I realized I didn't update to the latest version (5.0.2 instead of 5.1.1). So I decided to do that, when I realized I couldn't boot into recovery. Whenever I tried, the device would turn off instead. I downloaded Quick Boot, and when I hit to recovery, it instead just boots up as if it was just a normal restart.

Help would be appreciated.
