This was the correct sequence for the XE3000 as well. Thanks for sharing!
To recap:
- Power down
- Remove power cord
- Connect network cable to LAN port (WAN may work, did not test)
- Press & hold reset button
- Reconnect power cord
- Wait for Internet light to flash five times
- Release reset button
Was successfully able to update uboot from 2022.07-rc3 (Feb 21 2023) to 2022.07-rc3 (Feb 25 2025).
Interesting that only the timestamp changed and not the RC versioning, but whatever....
After the upgrade was completed, I noticed the lights cycle on my XE3000, so I removed the manual DHCP assignment, browsed to the normal admin panel and confirmed the device was up. Went back into uboot mode to confirm the versioning change, and then rebooted once more to restore normal operation.
