Hello. About 2 days ago I've bricked RB2011 by firewall drop all. I bricked it dozen of times at the beginning but typically procedure was simple - factory reset, load backup settings. However this time after reset router remained "bricked".
Well i didn't brick it for quite a long time recently, like almost 2 years so there's a lot of changes in config since old resets. Anyways - it didn't load expected default config this time. Repeating process few times gave the same results. Luckily it has LCD so i decided to check what's going on aaaand... config was completely blank. Like null, nothing, zero. No IPs/subnets on any port, even switch ports were not set to use any master port, everything as generic as it can be. I used LCD to set up IP and netmask on one port and logged in. There were no rules. Completely. For anything. Of course backups were still present on storage so I loaded most recent one but the problem is that it's quite inconvenient.
How can i set or fix this default config to actually reset router to some working settings, not brick it just in different way?
