One +has to remove all screws (in order): 4 top cover screws, 4 side cover screws +(one side is enough), 4 mainboard screws, 4 CPU screws (under DIMMs). Lift up +the mainboard and turn around it. The flash chip is near the SoC on the DIMM +slots side. Use a clip (or solder the wires) to program the chip.
