ProGCC Troubleshooting Guide

2min

Common Issues

  • Sticks are not centered
  • Sticks are drifting
  • Disconnecting Intermittently

See our table below listing common issues and potential causes.

Issue

Cause

Solution

Controller disconnects when the USB Cable is wiggled.

Defective USB-C Cable.

Contact support@handheldlegend.com to receive a replacement cable.

Controller does not work when plugged in until Plus/Home is pressed.

Defective ribbon cable or defective soldering on ribbon connector.

This is likely a production issue. Take photos of the ribbon cable and the ribbon connectors, send them to support@handheldlegend.com to receive support.

Controller is stuck in 'Smash Ultimate' mode.

'Ultimate Mode' is considered a trigger mode, and it is not toggled like Xbox Layout Mode.

Hold one of the button combinations for the listed trigger modes in our user guide.๏ปฟ

Intermittent Disconnects while playing games

Too much draw on 3.3v line

Solder the 47uF capacitor onto the controller, as described here๏ปฟ

Home/Minus not pressing right/always pressing right

Membrane isn't connecting correctly with motherboard

You can trim the membrane to fix this issue, as well as adjusting the screw tightness can resolve this issue. See the guide here๏ปฟ

Bumper buttons feel mushy

Membrane placement/ Brand

The membranes dictate the feel of the bumper buttons, you should make sure they are thoroughly seated. If you want a tougher button press then try the ExtremeRate brand membranes as they are springier than other unbranded ones.

ERM Rumble Motors not firing at all angles/at the correct times

Not enough power making it to the ERM motors.

Remove resistor R20, and bridge the connection with solder to allow more power through to the rumble motors.

Left Stick Acting As Dpad, only activates at edge of stick gate

Calibration went wrong.

Recalibrate the sticks of the controller. Hold minus while plugging the controller in, spin the sticks 5-6 times, and press plus to save. It will automatically reconnect the controller.
