I have tried updating it and its completely updated, and nothing that I can see internally is wrong like nothing looks water damaged, nothing looks bridged and nothing looks burnt but it will not connect. It will flash for a few sec then I tried using the sync button and it connected for about 4 sec but it seemed to disconnect when I touched a button but it would connect if I didn’t press anything after. I just want to know if this is a board problem or something else and if it is a board problem what board do I need to replace?
