V3 Hub Offline for 3 Years - Certificate Expired - Need MAC Whitelist

Hello, I am hoping a staff member can help me force a firmware update.

​I have a SmartThings V3 Hub (IM6001-V3P) that has been sitting offline in storage for about 3 years. Because it was offline for so long, the factory certificate has expired. When I try to onboard it, it gets stuck on the downloading update screen (or throws error 12-002) because the server is rejecting the expired certificate.

​I know from other threads that the backend engineering team needs to temporarily whitelist my MAC address to allow the new firmware to push through. The hub is currently plugged in via Ethernet, powered on, and waiting.

​@nayelyz @Itati - Would either of you be able to assist me with getting this MAC address whitelisted? I can provide the MAC and Serial Number via Direct Message as soon as you are available.

​Thank you!

Thanks, i did try blocking the UDP port 123 but that did not work either.

Follow the guide in the link I posted above. You need to remove the port block to complete the download.

I finally managed to get it done, by blocking the UDP on my router.

Thanks a million!
