What is ISP pinout?
ISP in system programming allows us to have direct access to the eMMC/UFS memory with the device still soldered to the PCB (printed circuit board) using a proper box/dongle, such as Flash64 UFI, Easy-JTAG, or Medusa.
By using the ISP pinout, we can perform operations such as a full dump, firmware update, boot repair, FRP removal, and security backup without requiring a chip-off procedure. That way, we reduce our time, costs, and risks of damaging the PCB
