    • Unlock the four rubber feet by turning them 90° counterclockwise using your thumb or finger tip.

    • There is a tiny mark on every foot facing the bottom edge of the OP-Z. After turning them they should face towards the short edge where the on/off switch is.

    • When turning the OP-Z over again the bottom plate should come off by itself (thanks gravity).

    • If the bottom plate won’t come off you might want to make sure every foot is rotated correctly and gently tug on one of them.

It worked! Sort of. I bought a highway flex cable replacement and a new battery hoping it would solve an issue. The good news is I was able to replace it, and it’s function as before I replaced the flex cable. The only challenge really was that the audio cable plug in the new flex cable assemble was slightly bigger than the one I removed. I really had to force it down. During reassemble it was important to start left to right too - and it was easier to plug that last cable before installing the audio and USB C sockets. The issue I was trying to solve: My OP-Z will only power on when plugged in. I bought the OP Z used, and it worked fine for a while. But for reasons I can’t explain it stopped working with battery power alone. I tried all the solutions I found online including resetting the battery, firmware, etc. I’m just sharing this in case someone else has the same issue. Other than that, the new flex cable works just like the one it replaced, and I have an extra one now! Thank you!!!

I didnt replace my highway flex cable but I did repair the rotary encoders cuz the magnet holders kept popping out of the bearings.
