Frsky ACCST V1 Firmware Downloads
If you need to use your Frsky X series receiver with a third party radio such as the TX16 you will need to use ACCST V1 firmware. New firmware such as ACCESS and ACSST V2 firmware is not backwards compatible with third party radios anymore.
To make things easy, we have setup a shared folder that includes all of the latest V1 firmware.

Folders are arranged by item FCC (Non EU) and EU LBT firmware (EU folder). There are also some special variations such as Fport, but only use these if you know why you need them.
Please note you will need to flash the same version ACCST V1 firmware onto both your receiver and your XJT compatible TX module in your radio. So if you flash EU firmware onto your receiver, you will need EU firmware on your XJT transmitter module.
We have ACCST firmware for the following receivers:
- XSR
- R-XSR
- XM
- XM+
- R-X8R
- R-X4R
- XJT TX module
