update from 220 to 225

Hello!

I downloaded the latest firmware 225 from TE website and followed the simple instructions.
The last step in updating the OS is to press COM button or eject the device.
When I do that I get the the message “Could not find any valid firmware”.
My current OS version is 220.
I have tried several times to make sure I follow the steps correctly but I always get the same result.
Anyone know what I do wrong?
Thanks.

Did you unpack the downloaded file? It’s a file with the extension “.op1”, not “.zip”.

No I didn’t, no mention about that from their website. Thank you very much.
