Other installation methods
EdgeTX buddy , which allows you to install EdgeTX on the radio with just a web browser, or EdgeTX flasher , a tool specialized for installation, has also been developed, but it is currently at the prototype level.
Back up OpenTX firmware and various setting information
In case of installation failure, first back up OpenTX firmware and various setting information currently stored in the radio. For the backup procedure, see "Back up MODELs and various settings (EEPROM) in radio" chapter on " OpenTX/EdgeTX radio initial setup procedure " page and "Access to radio: backup Flash memory and EEPROM" chapter on " How to install OpenTX Companion " page. Then, copy the contents of the SD card to your PC, etc., or take it out from the radio and storage it.

Preparation of microSD card
OpenTX/EdgeTX radio uses a microSD card as a data storage area (compatible with SDHC standard). Image / audio data, Lua scripts, backups of radio and drone settings (MODEL information) are saved. See below for how to prepare the microSD card.Download EdgeTX firmware

and select the version you want to install.
There is also a version called Nightly, but since this is a Nightly build, a so-called beta version, it may be unstable or contain bugs. This version is for developers, so please do not use it for general users.
There is also a version with "-RC1" or "-RC2" .e.t.c. added to the end of the version name, which is the Release Candidate version. As with Nightly, it may contain bugs, so general users should avoid using it as much as possible.

If you scroll the release page screen and click the part written as "Assets", you will see a list of links to companion software for each OS of your computer and firmware binary files.
When installing using radio, use binary files.
Download the Zip file named "edgetx-firmware-v [version number] .zip".
Right-click on the link and download it to your computer. Unzip this in any folder.
Also, download the companion software here. Download the Zip file named "edgetx-cpn- [OS name] -v [version number] .zip".
If you unzip the binary file Zip file, you will get files shown in this figure.
These are files for each radio model.
Select the file that fits your radio.
If you don't know which file to select, open "fw.json" stored in the same folder with a text editor. You can see a list of model name and file name prefixes.
Store selected binary file in "FIRMWARE" folder of microSD card used for radio.
If the file name is too long, radio will not be recognized, so change it to a shorter name (up to 28 characters + ".bin") if necessary.
Then insert this microSD card into radio.
It may be good to take this opportunity to upgrade built-in multi-protocol module at the same time. In that case, the firmware for multi-protocol module is also stored in "FIRMWARE" folder. For how to upgrade the built-in multi-protocol module, see How to update radio firmware .
