I have an RB 951-2n which was set up as a station bridge, client to another one used as an AP. The AP was upgraded to 5.20 successfully via Winbox. So I took the station side box to the vicinity of the AP for a good connection and then Winbox would connect to it. I dragged the 5.20 files into the box and waited until the transfer finished. Then I rebooted. It didn't come up.
So I have tried to reset it, using both the front button and bottom shorting pin. It doesn't. I've never done that procedure before so I'm not sure about the timing, but I tried a few times, and used an old old laptop as a test jig whose IP didn't matter. So I tried it as 192.168.88.2, and as its old address (the real subnet here). I think I'm getting the home page with the login screen, though that *might* be the browser confused by the cache - when I used "admin" to log in it goes back to the same screen. And the LAN on the laptop keeps telling me that it's disconnecting and reconnecting.
Any clues about how to really hard reset this thing, or otherwise recover? Thanks.
