Thanks @Daumantas .
I am trying to upload via the /index.html page. I only mentioned the /uboot.html as it is not even loading.
I can’t get into OpenWRT at all - no CLI, Web UI or anything is loading.
Not sure what else to do at this stage - for now I have purchased another RUTX50 unit and running stock firmware (although I have to run an old version as GPS/AVL is broken in 7.0.6.x versions).
I really want to get this bricked one working again though…
Thanks,
Shane.
