For $29/mo, we provide access to advanced level technicians who will answer your questions on any Macbook board related matter to the best of their knowledge promptly & walk you through how to solve your problem so you can deliver a working board to your customer.
Or you can be a piece of shit like me and solder the flex directly to the board. No one has the patience to wait for me to buy the scrap boards and when I do the connectors look worse than the connectors I am replacing. It is doable.
