That's great (for you), but there's no telling what "works like a charm" actually means, and no real way to tell if the specs as-advertised still match the specs-post-repair. This is also why Apple doesn't bother with board level repairs on an individual basis.

For some people, that measure or metric doesn't matter, and that's fine, but it by no means is a universal "see this is better" approach. And I say this as someone who does board level repairs. On iPhones. (and that mostly came about because people tried to replace the screens on their phones with the power on, blowing the backlight circuit)

Doing something as a one-off is nothing compared to doing something world-scale.
