Samsung A125F (Galaxy A12) eMMC dump at binary revision U2, supplied as a 250 MB ZIP. A technician loads it into an eMMC programmer such as Easy JTAG, UFI or Medusa to restore a board that is dead after a failed flash, or to prepare a new chip for replacement. Connection is through ISP pads or a BGA socket adapter. The bootloader revision of the phone must equal U2 to boot correctly. Save a complete read of the original chip first, since the EFS partition with IMEI and calibration is unique per device.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @wzcare. Enginerys does not host this file.
