The secret gesture was kinda finicky on my PW3. Especially because I misunderstood "double finger tap" as "two taps with a single finger". However I'm stuck on the Jailbreak part. I copied the files to the directory:
Step 3 says "demo-${YOUR_DEVICE}-${YOUR_FW_VERSION}.zip", do I need to add the "demo-"-prefix to the zip file? Also, do I just disconnect the USB cable afterwards to get back to the demo menu? Doing so, and continuing to the "Get Started"-menu just shows the "Getting started" document.
