Twiddler

Here are the steps to upgrade your firmware:

1. Plug into USB.
2. Identify which firmware you are running by opening a notepad on the host device and pressing T14F2R on the Twiddler. The firmware version will be shown after the “ver=”
3. Download and unzip the latest firmware here: Twiddler Firmware
4. Plug the Twiddler into a computer via USB, mount the flash drive, and copy the Twiddler.bin file to it.
5. Eject the flash drive using the Host devices Eject function. It is critical that the .bin file is fully written to the drive so gracefully ejecting the drive is critical. If data is being written to flash and power is cut, there is a high risk of flash corruption which will render your Twiddler non-functional.

1. Enter Bootloader Mode. (T14 Touchpad Click)
2. Unplug the USB Cable.
3. Wait until programming is complete.
