The issue of my phone lately wasn't just LCD but also with it's internal hardware. Already brought my phone at a professional technician, unfortunately they can't recover my data due to it needs a board replacement. Everything has been wiped out of its system, and I felt devastated that moment so I asked for any advice here but as I've read their comments, it seems there's no solution when we failed so.
When did you bring the phone to the technician? I'm sure right now they have a tool like jtag that can dump the whole firmware and files where you can use to flash to another working motherboard. Unless the technician you ask doesn't have a tool called jtag, UFI, or something like easy Jtag? Not all professional technicians have this because it's expensive.
How about the old motherboard do you still have the old motherboard?
I suggest you if you still have it look for another phone technician that has a jtag tool and maybe they can still dump the whole system from your old motherboard and transfer it to the new motherboard.
