[SOLVED]820-3536 - not reading serial no.

[Alan.L]

board was liquid damaged and charging didn't work. I've fixed by replacing ISL and Q7130

board now powers on, goto OSX etc..

but when I goto About this Mac, Serial number field is unavailable
same when I use ASD.

Blank Board Serializer software doesn't let me write serial.


I then desolder the SPI Rom and put in the programmer then read the dump. the serial is right there....


do I have a corrupt SPI rom or something else is fuked??

Most likely a corrupted rom, you might get away by removing the serial number and then flashing it back with BBS.

Duke most probably knows what to do

I read somewhere BBS doesnt work on retina board so I haven't try removing the Serial number. I know that I need to replace with the string "SystemSerial".

I get duke to do it as he know how to put ME region.


one thing to add... manufacture date is also missing. but everything else is there on cocobattery

 

[smiba]

I think coconutbattery gets the manufacture date from the serial number. I think BBS v1.1 still worked on the 2013 models but I might be mistaken. I remember using it on a Retina macbook before with success though

The bit that is showing has nothing wrong with it. Try this:

Make sure not to flash the status/config register. Deselect that and only flash code memory as to not mess with the "quad enable" bit.

it worked.

I can't believe this shit only has 4gb of ram. lol
