## RF Firmware Upgrade
-**Attention ⚠️️⚠️️⚠️️ There are 2 versions of the `Sonoff RF Bridge 433`: the `R1` and the `R2 V1.0`. Wiring for `R2 V1.0` RF firmware flashing shown on the right.

+**R2 V1.0** RF firmware flashing:
+
1. 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)
