Long time user/owner of RB2011UiAS-2HnD-IN, i upgraded my antennas.
In doing so, obviously i had to open the shell. After plugging new pigtails and antennas and re-plugging the LCD ribbon cable, i fully see the LCD options and screens, i can even swipe/pan through all the ports/virtual-ports, but every single one of them only show flatline graphs, no graph data at all. however the internal webserver /stats URL shows stats just fine.

Any clue what i broke? Does the LCD screen have a chip that deciphers stats? did i break a single ribbon-cable circuit that carries the data? or is there a way to software fix?

EDIT: SOLVED.
Defaults somehow reset to weekly, as soon a i set minute, they shown as expected.
