Updating your FrSky X20RS to ETHOS 26.1.0 and showing you exactly how to update your FrSky receiver firmware — both over the air (OTA) and using a wired connection.
I'm still relatively new to FrSky and ETHOS, so this is very much a beginner-friendly guide as I learn the system myself and share what I'm discovering along the way.
UPDATE: I forgot to update the Bluetooth module in this video – Go to FrSky Suite – FrSky Product List – Bluetooth
In this video I cover:
🔸How to download and use FrSky Suite
🔸Updating the X20RS transmitter to ETHOS 26.1.0
🔸 Why the bootloader needs to be updated first
🔸 How to back up your models and transmitter settings
🔸 What's included in the ETHOS update
🔸 ETHOS Simulator and Lua scripts
🔸 How to find and download receiver firmware
🔸 Updating a receiver over the air (OTA)
🔸 Updating a receiver using a wired connection
🔸 What to do if you accidentally install the wrong firmware
🔸 How to check your transmitter and receiver firmware versions
🔸 The difference between the bootloader, ETHOS firmware and RF module
🔸 A quick look at the FrSky TD-SR6 stabilised receiver
And yes… I also managed to plug a battery into a receiver backwards and smoked it 🤦♂️
£55 receiver: dead.
Two £85 servos: also dead.
Lesson learned!
So hopefully my mistake saves somebody else from making the same one!
I'm currently building a beginner-focused FrSky/ETHOS series, documenting my move into the FrSky ecosystem and sharing what I'm learning as I go.
The next video will be looking at setting up the stabilisation on the TD-SR6 and testing how well it actually works in the air.
If you're using FrSky and ETHOS, let me know in the comments what you'd like me to cover next.

⚠️ DISCLAIMER
I'm still relatively new to FrSky and ETHOS, so I'm learning this system as I go. If you spot something I've got wrong or have a better way of doing something, let me know in the comments.
The aim of this series is to document the learning process and hopefully make it easier for other people making the move to FrSky.
