as well as with build from https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=ramips%2Fmt7621&id=asus_rt-ax53u:

Installed it over stock 3.0.0.4.386.67508 via TFTP powering device on while holding reset button (installation via TFTP using UBOOT menu was unsuccessful after meny retries for some reason).
Also tried installation via SSH:
`mtd-write -i /tmp/openwrt-ramips-mt7621-asus_rt-ax53u-squashfs-factory.bin -d linux`
The result is the same.
