Anyone able to read/write EFI on 820-00875-A ?

Hi,
has anyone be able to read the EFI of of a 820-00875-A or 820-00875-01 (A1708) Logicboard without desoldering the EFI Chip with TL866A? My board has a mx25l6473ezni chip by MXIC. But some other Logicboards seem the have the Winbond SpiFlash W25Q64FV on it.
My logicboard got water damaged and I bought a logic board of ebay which had efi lock .. So I bought a TL866A Programmer and hopefully anyone can help me on this one.

Cheers

EDIT: Also people who have desoldered it can tell me how they attached it to the Programmer.

you can try solder wire cable on and then connect direct to your tl686 programmer ,
or desolder chip and solder wires on all pinc of the chip and wires to tl866
regards.
