I went to the original Vendor website on the router. I uploaded a signed image from OpenWRT. I booted into this image from OpenWRT to install it. I never touched the command line. I installed this a few months ago.
i never had such device with such UBI stuff , i can only suggest to use USB TTL to console port and see what is in there, but try use Putty to connect via ssh, or just
root@AP2:~# ssh 192.168.222.1
Host '192.168.1.1' is not in the trusted hosts file.
Do you want to continue connecting? (y/n) y
root@192.168.1.1's password:
you likely installed a snapshot, which does not include LuCI (the web interface).
When you are connected to the device via ethernet, are you able to get an IP address on your computer? If so, what is issued (IP, subnet mask, dns, and router/gateway)?
Can you successfully ping 192.168.1.1?
Can you get in via ssh (username root, password is blank) to 192.168.1.1?
You really need to answer psherman's questions first and stop uploading random stuff to the router, don't break what ain't (necessarily) broken yet by impatience.
