Asus RT-N12 VP B1 does not get updated

There is a device Asus RT-N12 VP B1.
Firmware Version|OpenWrt 22.03.2 r19803-9a599fee93 / LuCI openwrt-22.03 branch git-22.288.45147-96ec0cd
Kernel Version|5.10.146
was installed. Recently I tried to update it with openwrt-22.03.5-ramips-mt76x8-asus_rt-n12-vp-b1-squashfs-sysupgrade and openwrt-22.03.3-ramips-mt76x8-asus_rt-n12-vp-b1-squashfs-sysupgrade and it had no effect. I used both methods LuCI Flash new firmware image and ssh sysupgrade. Did anyone face with that?
