 From time to time SparkFun will release new firmware for the RTK product line to add and improve functionality. For most users, firmware can be upgraded by loading the appropriate binary file located on the [releases page](https://github.com/sparkfun/SparkFun_RTK_Firmware/releases) or from the [binaries repo](https://github.com/sparkfun/SparkFun_RTK_Firmware_Binaries). Once the firmware is downloaded, loading the firmware onto an RTK product can be achieved by using one of the following methods:
 
-* [GUI Method](https://docs.sparkfun.com/SparkFun_RTK_Firmware/firmware_update/#updating-firmware-from-gui): Use the [Windows GUI](https://github.com/sparkfun/SparkFun_RTK_Firmware_Binaries/tree/main/Uploader_GUI/Windows_exe) and a USB cable.

 * [SD Method](https://docs.sparkfun.com/SparkFun_RTK_Firmware/firmware_update/#updating-firmware-from-the-sd-card): Load the firmware on an SD card, then use a serial terminal with the *Firmware Upgrade* menu
 * [WiFi Method](https://docs.sparkfun.com/SparkFun_RTK_Firmware/firmware_update/#updating-firmware-from-wifi): Load the firmware over WiFi when the device is in WiFi AP Config Mode
 * [CLI Method](https://docs.sparkfun.com/SparkFun_RTK_Firmware/firmware_update/#updating-firmware-from-cli): Use the command line *batch_program.bat*

-In the rare event that a unit is not staying on long enough for new firmware to be loaded into a COM port, the RTK Firmware (as of version 1.2) has an override function. If a file named *RTK_Surveyor_Firmware_Force.bin* is detected on the SD card at boot that file will be used to overwrite the current firmware, and then be deleted.

-The [SparkFun RTK u-blox Firmware Update Tool](hhttps://github.com/sparkfun/SparkFun_RTK_Firmware_Binaries/tree/main/u-blox_Update_GUI) is a simple Windows GUI and python script that runs the ubxfwupdate.exe tool. This allows users to directly update module firmware without the need for u-center. Additionally, this tool queries the module to verify that the firmware type matches the module. Because the RTK Facet L-Band contains two u-blox modules that both appear as identical serial ports, it can be difficult and perilous to know which port to load firmware. This tool prevents ZED-F9P firmware from being accidentally loaded onto a NEO-D9S receiver and vice versa.
