## Version no longer supported ![Image: CLI Warning Dialog](https://i.imgur.com/YK60AtF.png) * [Configurator 11.0](https://app.betaflight.com/) supports only 4.3 and later. * [Configurator 10.10](https://github.com/betaflight/betaflight-configurator/releases/tag/10.10.0) supports only 4.2.11 through 4.5.x. * [Configurator 10.9](https://github.com/betaflight/betaflight-configurator/releases/tag/10.9.0) supports only 4.2.11 through 4.4.x. * Betaflight has fully dropped support for F3 since version 4.1.0. * [Configurator 10.8](https://github.com/betaflight/betaflight-configurator/releases/tag/10.8.0) may still allow configuration of older firmware, but may not list very old firmware. Instead, one must download and flash local .hex files. ## Recommendation - backup everything: * close the dialog, remain in CLI. * type `version`, press enter. * type `diff all` , press enter. * type `diff all defaults`, press enter. * type `dump all` , press enter. * press the `Save to file` button, keep this file for prosperity. ## If it's not broken, don't upgrade until you know what you are doing. * Flashing firmware erases everything! There will be no restore options except the file you saved above. * If the flight controller is F4 or later, then command-outputs (newly saved file) will tell you what target to choose. Use the "Update firmware" button to flash latest firmware for that target. You'll likely need the saved file for some of the settings, but many variables have changed and manual setup will be required as well. * If the flight controller is F3, then you can find an [old 3.5.7 version of firmware here](https://github.com/betaflight/betaflight/releases/tag/3.5.7), or you can try [F3 Performance edition here](https://github.com/spatzengr/betaflight/releases). * ![image](https://hackmd.io/_uploads/Hy3F9fUBR.png) ## Other stuff * Here is more info about not-connecting problems: https://hackmd.io/@nerdCopter/rJv5TUrQ2 * If something is not right with the target, then maybe it needs some custom defines: https://hackmd.io/@nerdCopter/ByheaoLQh * This config migration tool exists: https://bf43-safe-migration.robertodedomenico.it/, but i don't know much about it.
