When following this guide; https://openwrt.org/docs/guide-user/installation/sysupgrade.cli
I can't seem to get step 4 to work. When I run step 3, I dont get the expected "FILE_NAME: OK" in my command window output. Does this guide need ammending or is it perhaps that the image I am using is not a sysupgrade file and therefore not going to work anyway?
This is the upgrade .bin file I am using;
I can actually follow the guide and run sysupgrade -v /tmp/*.bin and get a successfull upgrade, I'm just unable to verify the firmware checksum.
