I can't install OpenWRT after rolling back to the official Cudy TR3000 v1 firmware

Hello, has anyone encountered the problem of reinstalling OpenWRT on Cudy TR3000 v1 after rolling back to native firmware? The firmware loaded out of the box without any problems, although I don't remember what kind of firmware factory or sysupgrade downloaded, but it worked fine. Then, for certain reasons, I returned to stock via hard reset via tftp64, but then I had to return to OpenWRT again. At the same time, when installing the file, I get the error "Invalid file, try again" I tried different official firmware, none of them allow the custom. I tried to flash through tftp64 by changing the file to recovery. The download program shows progress 100% and disappears, while the router flashes lights, and when the power is reconnected, the official firmware also remains.
