Issues with Flashing

On the hardware side, everything seems fine except for the initial part where i accidentally pushed the no-solder headers into b- and b+ which resulted to the no solder pins popping out. But i popped it back in and reassembled just fine. Everything was flushed, clicked nicely. However, the problem that i have is due to flashing. I followed joe scotto’s youtube tutorial for that and im fairly comfortable with software. I flashed the left, then right side and was able to connect the board via bluetooth. Here is the problem: Only the ‘asf’ and ‘jl’’ keys are working. So basically only 6 keys, 3 keys on each side are working. Furthermore, on input, it emits “xcv” and “m,.” Instead of the default which should be “asd…” as mentioned above. Note: i did not change the keymaps, so these are the default mappings. Furthermore, there is nothing display on the nice views. When i plug in the power, it shows black static dots, but there is no concrete display. At this point im not sure if its a hardware or software issue. Can i get some help on this please?
