For radios running erskyTx and OpenTX, there is an option to flash a precompiled firmware file to the multiprotocol module:
- OpenTX: using the SD card browser
- erskyTX : using the transmitter's Bootloader mode.
What you need:
- A precompiled multiprotocol firmware file (.hex for Atmega328p or .bin for STM32)
- A Flash from TX bootloader installed on an Atmega328p or STM32 multiprotocol module
- A means to get the firmware file onto the transmitter's SD card
- Copy the firmware file to the radio's SD card - it doesn't matter where you put it
- Switch the radio on normally and use the radio menu to locate the file on the SD card
- Highlight the file and press the ENTER button
- Choose Flash internal module or Flash external module as appropriate
- Push both horizontals trims inwards (close to each others) while powering on the radio
- The screen title should indicate
Boot Loader V2.9Ready
or newer - Launch the
FlashMulti_xxx.app
app from theRun App
menu - The App version at the bottom right of the screen should be
28.Aug.18
or newer - If everything is correct you are ready to upgrade the Multimodule firmware
- Download the latest zip file of the erskyTx firmware or this file for the T16.
- Extract the .bin file corresponding to your radio in your SD card
\FIRMWARE
directory - Download the latest Flash Multiprotocol Module app for your radio. For the T16, it's in the previous file.
- Copy the .app file in a folder called
APPS
at the root of the SD card (if the directory does not exist create it) - For erskyTx
- Power on the radio in

- Check by rebooting the radio in bootloader mode that everything is ok
- Either:
- Connect the transmitter using a USB cable and power it on, or
- Remove the SD card from the transmitter and mount it using a suitable reader
- Copy the pre-compiled firmware file into the

- Long press again to flash the selected file to the module
- When flashing has finished, long press EXIT to reboot in normal mode
- If the flashing procedure fails try to redo the process with

enabled - Make sure to have the latest bootloader on the MPM module before attempting to Flash from the TX:
- For an Atmega328p module use the bootloader bundled with the
Multi 4-in1 AVR board 1.0.3
or later - For a STM32 module use the bootloader bundled with the
Multi 4-in1 STM32 board 1.0.9
or later
- For an Atmega328p module use the bootloader bundled with the
