TT MAX \ TT PRO Controller V6.8 Firmware -2026.4.13
GuliKit TT MAX \ TT PRO Controller V6.8 Firmware:
1. Fixed an issue where occasional joystick jitter occurred when mixing APG and button mapping functions on the rear buttons.
* Starting from firmware V6.7, the Joystick Adaptive Mode and Anti-Rebound Mode have been merged and upgraded to “Dead Zone Mode 2.0” — the joystick retains a physical dead zone, while achieving a dead-zone-free experience in-game for the cursor area. In FPS games, this allows you to release the joystick without stick drift while still maintaining precise aiming. In Super Smash Bros. on Switch, it enables reliable dashes without accidental turnarounds.
Upgrade Method:
1.With the controller powered off, connect it to the computer using a USB C to A cable with data transfer functionality.
2.Press and hold the APG button( the double-square icon button) on the controller, then press Home button. The controller will be powerd on and a "GuliKit" USB drive will appear on the computer,and the file on the USB drive is the current firmware version number of the controller.
3.Unzip the downloaded upgrade firmware file first,next copy the corresponding "***.bin" file to the root directory of the USB drive.
After a few seconds, the controller will automatically power off and the USB drive will disappear from the computer, indicating that the upgrade is finished.
Note:
• The controller will automatically power off after the upgrade is completed. Do not unplug the USB cable before that.
•If you want to stop upgrading during the process, you can just turn off the controller by pressing the OFF button on the back, and next press the Home button to power it on to exit the upgrade mode.
• After the upgrade is completed, it is recommended to calibrate the joysticks on the controller. With the controller powered on, simultaneously press and hold the "L, R, D-pad Left, and A" buttons for 6 seconds.
Then fully move the left and right joysticks in complete circles for several times. The controller will vibrate once to indicate that calibration is completed.
• Since different decompression softwares have different file caching methods, it is recommended to unzip the firmware package first before copying the firmware for controller upgrade. Directly dragging or copying the firmware from the compressed package may result in unsuccessful upgrade or dead controller. If you encounter such a situation, please unzip the firmware package first and then follow the correct steps to run the upgrade again to resolve the issue.
• Due to the security zone for the firmware upgrade, you can check the updated firmware version number by restarting the controller at least once after the upgrade is completed.
