Does it really have an F tier PCB? Like it broke on you? Or the PCB is laggier than 1 frame (and Tech Talk as a whole have hard evidence of this which I'm pretty sure none of us sees an issues with the HRAP V's PCB)? But you can use them, but the PS360+ will never get true PS4 support, so don't even bother with that for PS4 support. Use a multimeter to find the pins of the side buttons and connect them to the UFB. Find the touchpad key as well the same way, but touchpad tracking support isn't in the UFB atm. Then wire up the face buttons, joystick, and options button all via the original wires that went into those inputs. If you still need the wiring schematics, then use the search function here if we have them. But do you really need the upgrade tho? If you need a cheaper alternative the Brook PS3/PS4 PCB also works great.
Open it up, grab a wide flathead, put it in the bottom of the shaft and tighten the balltop with your hand.
Fairly common, take it easy lol
That is, if the ball is loose. If you just don't like that everything is spinny, then you're holding the balltop wrong.
