The utility nrf2hex has failed -Fix

The two reasons this error occurs include: 1.) the Nrf2Hex file is not in the same folder as the firmware update batch file. Confirm that this file is in the same folder as the firmware update file and attempt to run the update again. 2.) The device drivers for the Segger J-Link have not been installed correctly. This can be resolved by updating/reinstalling the drivers. Please note that a Segger JTAG is required to install or update the firmware on the BL600. The drivers for the Segger J-Link are found at the following link: https://www.segger.com/jlink-software.html?step=1&file=JLink_496l
