Firmware - Freedom computer

FW manager for Windows can automatically download the latest version of firmware from Internet or you can use firmware from a file (off-line). It is easy to install and use. No prior driver installation is necessary, no special IT skills required.

FW manager for Mac computers. Download the file and try it. It is a new SW. Please report any issues. Thank you.

You can still use an older method of firmware upgrade: For upgrade, you will need the new firmware, upgrade manual , loader program and device driver. The environment is avaliable for Microsoft Windows only. Since FW version 1.7, the package contains two files with firmware:

• FD.bin.enc is for older units with OLED display 2.0"
• FD3.bin.enc is for new version with TFT display 2.4"

It is not possible to upload wrong firmware into the computer. If the DSLoader program doesn't recognize TFT version (it says "Unknown device"), please update DSLoader (at least 1.5.5 required).
