Who uses the Yeastar TG1600 gateway , tell me how to update the firmware?
Bought there firmware 56.18.12.46, go to System \ System Update, insert the firmware image.yeastar.com/Yeastardownload/91.3.0.21.bin into the URL, press Start, writes that it has been updated and asks for a restart, but after the restart the firmware is the same ...

What am I doing wrong?

It says on the download page:

Before using the TG V3 firmware 91.2.0.4 to upgrade, please make sure your TG gateway's firmware version is 91.XXX or its SN starts with 331; using this firmware on a non-V3 gateway will result in system crash.

And there is a link to the instruction: *TG Series Firmware Upgrade Guide
Make sure that the serial number starts with 331 and if so, then update the firmware via TFTP...
