I declare that I am not a repair master, just an ordinary user! First, let me wish all the masters a Happy New Year! Now, back to the point. I have a Xiaomi 3 with a 64GB memory whose screen is broken, and it seems a waste to throw it away. Since I often browse various forums, I am very interested in posts about converting phone EMMC into USB drives. This afternoon, I suddenly decided to give it a try! Let me introduce it to you in detail.

Wiring process. Fortunately, there are only 9 wires! It took me nearly an hour to complete. If it were a master, it would probably take just a few minutes.
Soldered successfully on the first try! The read and write speed tested with a phone and OTG is around 10MB/s. Using a computer, the read and write speed is about 20MB/s. I am quite satisfied! By the way, here’s an electronic magnifier I made using a salvaged camera!
