Hi, @andy.manager

I don’t have Mini5G with me, this moment…

But…
I try to update the modem firmware of my BR1minihw3 running 8.5.2s042 build 5263.

No issues with the upgrading process.

Just checked on other BR1 Mini 5G with WIFI. Same version 8.5.2 and got same error.
Please try again later.

Going open ticket.
