Mobile 50-Pin FPC Pinout Research

I am integrating a 50-pin FPC connector taken from a mobile phone into a brand-new product, but I have absolutely no documentation on it. Your task is to uncover every signal on that ribbon—power rails, data lines, control pins, grounds—so I can design a compatible mating board without risking damage to either side.

Here is what I can supply once we start:
• Clear macro photos of both sides of the flex and its mating board
• A working handset for continuity checks or live probing if needed
• physical pcb can be couriour within india

What I need back from you:
• A complete pin-by-pin table listing signal names, functions, and voltage levels where applicable
• A brief description of the testing or reverse-engineering method you used (tracing, continuity mapping, logic analyzer captures, etc.) so I can replicate or verify your results
• An annotated image or diagram showing pin numbers and their assigned signals

Accuracy is critical, so please outline how you plan to confirm each assignment—whether through reference schematics you already possess, ohmmeter tracing, oscilloscope waveform identification, or any other proven technique.

If you have prior experience mapping mobile phone FPCs, teardown documentation, or access to industry component databases, mention it; a quick turnaround based on solid evidence is what matters most to me.

I am ready to begin as soon as you are.
