Hi All,
during last update I did mistake and hit update button instead of upload file mannualy. It tooks long time to update and in meantime i stop it and tried
to upload new firmware in a standard way. It was not possible even GUI gives me "success" message.
Finaly I did NAVRAM erase using amtm. It not helped but finally I was able to update firmware using asus restoration tool.
After that router is working, navigation is slightly slower and I feel that not all function are working as it should. I see below errors in the system log.
I know that this is EoL product but maybe someone has idea what was broken during Navram erase process.
Thanks!

ECC errrors in your flash. This typically indicate a failing flash chip, so it`s a hardware issue.
 
Or maybe you've just corrupted it by your errant procedures. I've seen brand new flash drives irretrievably corrupted when mishandled too. And nothing I try will typically save it. I just throw it away and chalk it up to a lesson learned.
 
Thanks for quick reply. I suspected that a replacement would be necessary. Was hoping to wait a while longer and switch to a device with wifi7. Thanks.
