Access to radio: backup Flash memory and EEPROMRadio that uses OpenTX/EdgeTX has a "Flash memory" that stores firmware and boot loader, and an "EEPROM (Electrically Erasable Programmable Read-Only Memory) that stores model information and various setting information inside.
As a starting point, let's back up the initial firmware and EEPROM installed in the radio to your computer.
Then connect the radio to your computer with a USB cable and wait for a while.
This backup file can be written back to the radio by [Write Backup to Radio] menu.
