Twiddler

Here are the steps to upgrade your firmware:

1. Plug the Twiddler 4 into USB.
2. Identify which firmware you are running by opening a notepad on the host device and pressing T0F1R on the Twiddler. The firmware version will be shown after the “ver=”
3. Download and unzip the latest firmware here: Twiddler Firmware
4. Rename the bin file to Twiddler.bin and Copy it to the Twiddler.
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.
6. Unplug the Twiddler 4 from the USB.

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

1. Confirm the new firmware is running by opening a notepad on the host device and pressing T14F2R on the Twiddler. The firmware version will be shown after the “ver=”
2. Delete Twiddler.bin off of the Twiddler's flash drive.
