Lost 4Q RGB and Connection to Software After Firmware Update

There is an uncommon glitch that can occur after updating the 4Q's firmware that causes the keyboard to lose connectivity with the software, which in turn causes a loss of RGB functionality as well.

To resolve this, please do the following steps in order:

1. Locate the Q Software folder. It is likely under the file path C:\Program Files (x86), in a folder named "Das Keyboard Q".
2. Delete/uninstall all of these files completely.
3. Locate any Das Keyboard firmware .exe files that you may have downloaded in the past and delete them. They are likely located in your computer's Downloads folder.
4. Restart your computer.

After that is done, please do a manual firmware update. This will help the keyboard communicate with the Q Software. Manual firmware update steps:

1. Download the firmware for your keyboard's layout:

US Layout 4Q: https://download.daskeyboard.com/q-software-releases/Firmware-releases/DK4Q/DK4Q_US_Firmware_21.27.0.exe

EU Layout 4Q: https://download.daskeyboard.com/q-software-releases/Firmware-releases/DK4Q/DK4Q_EU_Firmware_21.27.0.exe

1. Make sure the 4Q is the only keyboard connected, then open the folder containing the downloaded .exe file, run it, and follow its setup steps. Make sure the keyboard does not disconnect during this process.

After this is done, reinstall Q Software and use your keyboard as normal.
