Ender3 updated MB, and still Marlin 0.0.6 with issues

Been working on this printer after it went out all of a sudden one day. Bought brand new, was able to do a few prints, then tried doing another print, stopped working. Thinking of going to a different company.
Tried updating the board to a 4.27 ver and still can’t read a card with slices on it, and also the BT touch doesn’t work or will not work right, even with the x axis connected. Thinking of buying a Bigtree (sp?) board or just go with a different company. so frustrating just to try a test print and nothing works right. So has anyone had any luck with the updated boards or just went with a new printer all together?
