I'm trying to recover my data from my old android smartphone. So I chipped off the emmc chip and insert the emmc chip to emmc reader. After that, I connected the emmc reader via usb-sd reader to Pc, nothing happened! Pc couldn't recognized anything. Is that means emmc chip has a problem with the memory? Or is there are softwares to connect the emmc chip? Or is there are problems with the usb-sd reader?
