When programming a nRF9151 firmware on to Thingy91 X, I made a mistake and failed to change SW2 from nRF53 to nRF91 (the label is very small). The USB serial port no longer works so I assume this means I've wiped the default nRF53 SoC firmware? How can I restore the default nRF5340 firmware build(s) for Thingy91 X?
I've looked in thingy91x_mfw-2.0.2_sdk-2.9.0-preview.zip but this only seems to have sample firmware builds for the nRF9151. Can you provide existing default .hex files for the nRF5340? or if not then perhaps point me to an existing sample app/builds?
Looking at https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/thingy91x/thingy91x_updating_fw_programmer.html#updating_the_firmware_on_the_nrf5340_soc it it looks like 2 builds are needed - for the application and network core? (I'm not sure if I'll need to reprogram both)
Since then I've programmed the nRF9151 with SW2 set to nRF91 - and it seems to be communicating well (but I do need USB serial port access).
