yes but it cannot be recognized by the programmer. Look in the picture. Also is not in the supported list of TL866a.

you have try one chip other ?
It may be damaged when you remove it at a high temperature

 

[Lab Experts]

no the chip. is ok. I put it again in the motherboard and the mac turned on and show me the lock button. This is the reason that I need to flash it. Is that possible with this programmer? Which programmer did you use for this chip?

Yes, I think only is problem connect.

 

[Lab Experts]

This is for MX25L647E but I dont have this. I have the chip MX25L647EZNI-10G which is different. which not included in this list. But I will try a new connection.

 

[Lab Experts]

I tried a lot ways to read it. It is not possible. After a big research I found the programmer that It can read this chip. The programmer is RT809F . Maybe I must buy it. Right? thats your programmer that you had read this bios chip?

Finally I fix it with new empty chip from my chip supplier. The chip in macbook cannot be read it from any programmer. Maybe it is locked. So now we must replace it with new bios chip.
