Digi Connect WI-ME freeze after update

I have Digi Connect WI-ME with this data before firmware update:
Firmware (Version 82000977_G 05/03/2006)
POST 1.1.3 (release_82000941_G)
MAC Address: 00:40:9D:2A:99:83

I downloaded 82000977_M3 firmware , after a success update via webpage I rebooted the module, after this I am not able to reconnect.
I tried an hardware reset but nothing changed.
What happened? What can I do?

It’s a good rule of thumb with Digi devices to ensure the POST is up-to-date before updating the firmware (EOS), because some firmwares require that a certain POST version is running.

The current POST is 82000941_J and your unit is running an older revision, G.

This is my best guess as to the cause of the issue.

Do any of the suggestions in this KB article help you recover the unit?
