A free replacement firmware exists.

Get started

One known way to put open firmware or software on this device, easiest first. Each one links to the project's own instructions.

Before you start
  • Back up your data and settings (and the stock firmware, when the guide says how).
  • Check the exact model, hardware revision and firmware version against the guide: a close model may not work.
  • Charge the battery or use a stable power supply; do not unplug during the install.

ProjectKindOriginLicenseFreedom
EdgeTX (gx15 build)firmwarecommunityGPL-2.0Still non-free: bootloader · Cloud: noneEdgeTX is free and brings its own bootloader; the STM32 ROM bootloader used for USB flashing is closed and stays. An internal RF module runs its own firmware, free only when it is ExpressLRS or the DIY Multiprotocol module.
What "still non-free" and "cloud" mean

What stays proprietary or depends on the vendor's cloud once the project is in use, from the project's own documentation.
