I may have accidentally installed firmware 4 on my AR750S-Ext, the one from here:
I don’t seem to be able to use U-Boot now and am kind of lost on how to go back to firmware 3.
Can anyone help?
It can be the follow how to can help you:
Thanks but no.
U-Boot is not loading, no other reset option helps, also revert firmware does not do anything
I don’t know what U-Boot mean, so wait a little bit for the gl support.
I dont know the follow can help or not:
Can you SSH to the router?
If yes, use
scp command to copy firmware 3.x file to router, then use
sysupgrade command to upgrade.
@Leo thank you so much, this worked I am back to working router now.
