Hi Everyone
My MBP A1278 820-3115-B EMC 2554 had EFI password and unfortunately when I was going to program the bios, I didn't make a dump file of my bios and I did erase it and wrote with a file which I had, it died (after I did, I realized What I did
)
I searched everywhere of this amazing website and I found couple of cleaned and no mod dump files as same as my motherboard's serial and mlb NO. which admins replied to users who requested a clean dump file, then I replaced my serial NO. and MLB NO. with those dump files and wrote them on my bios and Finally, it turned back to the life
What I did:
1) My bios type is MXIC-MX25L6406E-M2I-12G and I programed the bios with "CH341APro Programmer" but instead of showing my bios type, it recognized it as MX25L6405D because the programmer software doesn't have it on the list but the size of the chip is 8MByte/64MBit and is the same as my bios chip size.
2) After I programed the bios, first thing to do was resetting NVRAM
Now I have some other problems:
1) it doesn't show any drives or bootable USB when I turn it on by pushing alt/opt button
2) When I try to reinstall maverick OS X by online recovery I have this error "COULD NOT FIND INSTALLATION INFORMATION FOR THIS MACHINE"
To resolve problems::
1) I have changed the date in terminal after flashing the bios but still got this error
2) Replaced HDD and rams but still got the error
3) For troubleshooting it, I erased the HDD in disk utility and also have installed Windows 7 on it to make sure there is nothing wrong with the HDD and sata cable.
Other than those things, I don't know what to do, please help
Thanks in advance
