I have not been successful to updating the firmware of the Thingy:53 board, and I have tried all methods indicated here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy53_gs.html
1. Updating through Bluetooth LE: The preloaded Edge Impulse firmware fails to connect, so I tried to update it with the nRF Programmer mobile app. After 10 attempts I managed to update it, however it still can't connect to Edge Impulse.
2. Updating through USB: This method fails for any firmware that I want to update, since it indicates the message "Error when fetching device versions...", so it does not activate the Write icon.
3. Updating through external debug probe: Following the steps in this method gives me this confusing message with the thingy:91 board:
Please update the firmwares of this board. I found a similar issue that was reported two months ago, and it doesn't seem to be solved: Problem with Getting started with Thingy:53
Kind regards
