Dolphin.dyl(TM) Pre-programmed BIOS EFI Firmware Chip For MacBook Pro A1286 2011 820-2915-B

Chip was dead on arrival, verified logic board and serial. Was soldered into place with a reflow station and still didn't work normal bios chip still works fine when soldered on. Obviously was a bad chip.EDIT:All in all the seller sent me a new working chip and was curtious and polite during the whole thing. I recommend this seller it's possible my chip I got at first was just a dud and it won't happen again.
