This guide will show you how to update or change the firwmare on your FRsky Taranis X9D Radio system.
FrSky EU Firmware
Recently FRsky has introduced a new EU versrion of the firmware to comply with regulations ( ETSI EN 300 328 certification). Overall this firwamre is exactly the same as other firmware, just that the TX module had an added setting to listen before talk to comply with the regulations. You will need to update both your X9D Radio firmware and the receiver firmware to the EU version in order for them to talk together. However if you prefer to use the regular version of the firmware by manualy changing the firmware as discussed below.
All of our FrSky products now ship with the EU version firmware.
How to Upgrade X9D Firmware
This is a great video showing you the process to update the firmware on your Taranis radio. You can download the latest version from the FRsky website, or from the OpenTX website
OpenTX Comanion is a PC software tool that you can use to backup, edit and share your Taranis radio’s settings. It can also simulate both a model’s setup and the radio’s own interface on the computer, so it’s a great tool to try things even without a radio. This tool is used to update the firmware so you can see a great OpenTX manual on how to use it, or download the extracted chapter below:

Alternative Method to update firmware via SD Card
There is an alternative method to this one outlined above if this is failing to work for you. Firstly, you can simply go to the FrSky website and go to the ‘How-to’ section, then the Taranis Plus page, where you will find a PDF file that will help you with this method; I will outline it here.
First remove the SD card from the battery compartment of the Taranis. If you have a micro SD reader, use this to read it via the computer. If not, you can select the USB mass storage option once the Taranis is powered on for mass storage and use the USB cable instead. To enter this bootloader mode, with the taranis turned off, while holding both trim buttons inwards, turn on the taranis, more details in step 4.
Download the firmware from the FrSky website and put the file (either mode 1 or mode 2 depending on what you’re using) into the ‘FIRMWARES’ folder
Please make sure the firmware filename is less than 8 characters long, otherwise the taranis can’t read the file, so you will probably have to rename it
Now put the micro SD card back into the slot in the battery compartment.
Turn on the transmitter in the ‘Bootloader’ mode i.e. push T4 to the right, push T1 to the left and switch on the power button, all at the same time. (You can now connect the USB cable if you do not have a SD card reader.)
- Then select ‘Write Firmware’, select the .bin firmware file you would like to upgrade to and then press and hold the enter (ENT button).
- Once complete, turn off your transmitter. You should now have upgraded your Taranis.
Second Alternative Method via DFU tool
If the above method does not work then there is another option to flash your Taranis via DFU (Dfuse software). We have a full guide on using Dfuse to flash taranis here.
Loading EU firmware onto internal RF module
This is done exactly the same was as shown above. However instead of selecting a .bin firmware file you will select the .FRK firmware file for either an internal RF or external RF module. This is applicable to Taranis firmware higher than 2.1 If you still have an older version bootloader on your Taranis then its best to first upgrade your taranis firmware. For more details check out our guide on how to upgrade your Frsky receiver firmware.
Otherwise we have a guide on how to upgrade the RF module firmware the old way which is abit more complicated.
