OS 12579405

If you somehow force fed a BIN file to your PCM that had been edited with a mis-matched XDF, then yes, that could be an issue. This situation would generate erroneous checksums that could "brick" your PCM.

If you are adamant about sticking with your 9405 original operating system, you will likely need to seek someone equipped and skilled with HP Tuners or EFI Live. As far as I can tell, there is no matching XDF file for use with OS 12579405.

Hey Rick and others thanks for the responses. Rick I am not stuck on using the bin file I have it is the only one I have and the bin from my original computer. I just need something that works. If you have any other bin files that will work for my 03 sierra then I will take it. The xdf files you told me about just don't work with my bin file I guess. I know you said you have done several with no issues. So I am all ears for help and info. Thanks again guys.

The 12587603 BIN and its associated XDF file should work for your 1 megabyte PCM. Did you find this set of files? They are on this site or I could send them to you.

I didn't find those files. I would greatly appreciate if you did send me the files. Hopefully I can get those to work for me. Still have not been able to get the fans working yet but I know I should be able to with these files. Thanks again.

Apologies for bringing this thread back from the dead, but it's the most recent I've found referencing 12579405 xdf.

Using the 2004 xdf linked appears to be extremely offset, nothing matches up with values that make any sense

That's because an XDF meant for 7603 absolutely will not work with a 9405 BIN.
