ATGU should drop you into u-boot.
Now it cant boot it
I upload initramfs to router and then run it with command bootm with address.
I use address from output of tftpboot

P.S i did it. I wrote it to wrong part
P.P.S i will write a guid what to do in this situations
Then post the reason to the failed boot.

Boot the initramfs then download the sysupgrade image and run sysupgrade. Often the sysupgrade script will take care of formatting the MMC flash for you and writing OpenWrt kernel and rootfs to the correct places. Poking around in the flash directly should be a last resort.

I load openwrt but i cant save any config or file. Because rom load without other files. What i need to do? I tried to do overlayfs but it raise an error
@slh
Which image? I dont understand
Then perhaps you should tell us, instead if winging it, and risking breaking stuff even further.
What part did you understand?
I need download sysupgrade. Untar it and write root it to rootfs patrition. But i dont understand which @slh image i need to get. I tried a lot sysupgrade images and it dosent work
You shouldn't unpack, nor should you write it, the sysupgrade command will do it for you.
Sysupgrade image link is at https://openwrt.org/toh/hwdata/zyxel/zyxel_nbg6817. Use the 22.02 image.
