Hello,
i sucessfully installed openwrt version 15.05 on my old NAS using this guide:
https://groenholdt.net/tag_nas_index.html
and this:
https://forum.archive.openwrt.org/viewtopic.php?id=58358
The thing is that i can not update to the lastes 18.06.1 release.
What i have done:
Installed openwrt 15.01 linke in the first link with the image of the 2nd link.
Devices boots up with 15.01 and now i want to update. If i use LuCI it uploades and reboots but comes back on with 15.01, so i tried to do the update on CLI:
