Samsung J710M (Galaxy J7 2016) eMMC dump at binary revision U4, stored in a 419 MB ZIP. Repair technicians write images like this with an eMMC box via ISP or socket to bring back a phone that shows dead boot after corrupted storage, or to load a fresh chip during replacement. The bootloader revision on your unit must be U4. Make a full read of the existing memory first, since the EFS data holding IMEI and radio calibration is specific to each phone and cannot be recreated from a generic dump.
