After upgrading the firmware, I cannot login the web server of WR41.

There is also no response from the digi device discovery software. Im’ very sure that it’s working well before the upgrade of firmware. At this moment, the LEDs flash in a very special way.

Please refer to the youtube video: https://youtu.be/BsirY4f4RTc

I didn’t find out any solutions related to this issue on the digi support website. Can you please help me?

You may have inadvertently uploaded the wrong firmware to the device (V1 vs. V2), or the upload may have been corrupted. Using FlashWriter to upload a know good (flashwriter) firmware file would likely be your next step to recover.

Hi

If you have a v2 there is also a document that can help to recover your router
