ZB-GW03-V1.2 Firmware Update

Hi all,
I have the ZB-GW03-V1.2() component, and since the begininning I updated the firmware uploading Tasmota-for-eWeLink.
Now this firmware is old and I would like to update to a new one more updated, but I do not know how to do…any support?
Thank you,
Marco.

Assuming there is in fact newer firmware available, wouldn’t you do it like the last time? Like the instructions in the link tells you?
