Asus RT-AX53U router does not boot after update openwrt-23.05.4

Hello
Asus RT-AX53U router
I installed openwrt 22.05 on RT-AX53U router.
After that I changed the bootloader to breed and flashed:
openwrt-23.05.4-ramips-mt7621-asus_rt-ax53u-initramfs-kernel
After booting I get the message
"System running in recovery (initramfs) mode.
No changes to settings will be stored and are lost after rebooting. This mode should only be used to install a firmware upgrade

Go to firmware upgrade…"

I update the firmware to: openwrt-23.05.4-ramips-mt7621-asus_rt-ax53u-squashfs-sysupgrade
The router no longer boots.
If anyone knows how to restore the boot, please tell me.

Sysupgrade to proper version from initramfs (or use asus recovery to revert to OEM firmeware)
initramfs is special image for netbooting working system, it is not meant to be programmed to router. Once you have OpenWRT you only need sysupgrade images.

There is no mention of breed bootloader anywhere in device page:

I installed the initramfs openwrt-23.05.4 firmware on the
Xiaomi Mi Router 4A Gigabit Edition router using the instructions:
https://4pda.to/forum/index.php?act=findpost&pid=95012258&anchor=Spoil-95012258-8
option #2. Everything worked out for me.
But the variables for logging into the Mi Router 4A system are not suitable for logging into the Asus_AX53U system. I can't find the autoboot.command values ​​with the boot flash value for Asus_AX53U.
I don't understand how they can be calculated?

These are 2 very different devices. Please restore factory bootloader , restore to factory , and install OpenWRT proper way.
What you are complaining is normal operation of ramdisk image - no persistence.

Thanks for the clarification, I'll try.

Unfortunately, I can't return to the stock firmware. The breed bootloader does not have a recovery mode. If I change the bootloader to uboot-RT-AX53U, will the asus Rescue_2102 recovery utility help me?

You have to ask for recovery in your bootloader hacking place.

I don't understand what this means and how to do it?

It means that OpenWRT works with OEM bootloader, and you need to seek help where you got that bootloader from.
