AR750S firmware 4

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 :frowning:

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.
sysupgrade openwrt-ar750s-3.203-0701.tar

@Leo thank you so much, this worked :slight_smile: I am back to working router now.
