Make sure you have previously flashed a Tasmota binary built with `RF_FLASH`. Refer to the [builds table](Builds) for pre-compiled binaries which include this feature. Otherwise the "Magic byte is not 0xE9" error will occur. 2. Set the module type to `Sonoff Bridge (25)` 3. This step will be different depending on your `Sonoff RF Bridge 433` hardware version. You will have to connect two wires: - 1. For `R1`: Connect `GPIO4 to C2Ck` and `GPIO5 to C2D`. This wiring will look DIFFERENT than the picture to the right. - 2. For `R2`: Connect `GPIO4 to C2D` and `GPIO5 to C2Ck`. This wiring will look IDENTICAL to the picture on the right. + 1. For `R1`: Connect `GPIO4 to C2Ck` and `GPIO5 to C2D`. + 2. For `R2`: Connect `GPIO4 to C2D` and `GPIO5 to C2Ck`. 4. Switch the ON/OFF switch on the board to 'OFF' to switch off the RF. 5. Power up the bridge via the 3.3V & GND pins. (See below if you need to power the device through the USB power port) 6. Go to the Web UI **Firmware Upgrade** > **Upgrade by File Upload** (introduced in v6.0.0a)
