RTK Express Won't Update

Kits
1

Dec 2024 - My RTK Express unit I bought in 2022 won’t update. It has v1.8 listed at boot-up. I just bought a new RTK Express (v4.0) to setup as a Base unit along with LoRaSerial radios for my old unit as a Rover. I have tried the update options in the guide but the software always reports an error in the update file (see the screenshot below):

I have tried other update version but get the same result. The unit works fine when I connect to my local NTRIP Caster (see photo below):

I can connect to the Express but always receive the error in the screenshot "
0.0 - Verifiying Image
0.0 No magic word found
0.0 ERROR: Image not valid.
0.0 Firmware Update FAILED.

What am I missing?
Thanks in advance for the help!

Is there a specific reason you’re trying to update it? I’d recommend not unless you’re having a problem (it looks like it is still functioning as expected, correct me if I’m wrong here)

If do need to update and you’ve already tried the OTA, WiFi, and Serial/GUI methods…the last resort is trying via the SD card
