Answer to "Where is the memory card"I just watched a handy person do the replacement on YouTube (a white guy living in China) it took him three weeks a special logic board holder, torch, microscope, special soldering ball grid and dozens of dead logic boards to practice the removal and replacement of the memory chip before he was confident enough to remove and upgrade his own with a larger one. He also had to buy a special board flash chip reprogrammer and reader. So while yes it’s possible to do this and in China there are ,any technicians who do this every day, this is an expert level repair and replacement. There are two YouTube people who do this repair. A man in New York Louis Rossman, the video I watched last night was a YouTube called strange parts, How I upgraded my iPhone memory by 800%… I wish you much luck.
