I followed steps 1..11 on https://oldwiki.archive.openwrt.org/toh/d-link/dir-505 to install openwrt-19.07.0-ar71xx-generic-dir-505-a1-squashfs-factory.bin
Everything looks good, I get progress reports, and a confirmation message that the firmware was successfully upgraded.
But when I repower the DIR-505 the original dlink FW start again :-/
Is there anything else I can do except repowering the device to get the openwrt FW started instead of the D-Link FW?
I appreciate any advice or hint...
