Intel ME 10.0 Corporate 5MB Firmware v10.0.50.1004



Note: Version Control Number (VCN) was increased to 5. No downgrade via FWUpdate possible after updating.

Changelog:

You didn't answer my questions. More information is needed. As I said, I need the exact model of the system from the link above. What problems are you facing exactly? Did you replace the PCH with one from the same Apple model?

1) Yes attach the dumped SPI image. Did you make it with a programmer or a tool such as Flash Programming Tool?
2) What iMac model you do have exactly? For example: iMac (21.5-inch, Mid 2014). I want to be able to find it HERE.
3) Download ME System Tools v8 (section C) and run MEInfo and MEManuf tools under Windows (Command Prompt as Administrator) after having installed the latest MEI-Only Driver (section A). What do they report?

So the Apple update is the "IM131_010A_B09" one which has this firmware inside:



We need to reflash the ME region. There are two options:

1) If you have a hardware programmer to flash the chip directly then attach me your full SPI dump. I will replace the ME region and then upload it for you to flash it back.
2) If you don't have a hardware programmer then you can easily reflash just the ME region directly using Flash Programming Tool (FPT) from within Windows.

So how do you want to proceed? If you choose 1, remember to attach the SPI dump.

Flash the attached file back. Afterwards you should boot into DOS (if not Windows) and use Flash Programming Tool with command fpt -greset to reset the ME state now that it's SPI firmware is reflashed.

Intel ME 11.0 Consumer PCH-H Firmware v11.0.10.1002



Note: Version Control Number (VCN) was increased to 13. No downgrade via FWUpdate possible after updating.

Thanks to Intel for the new firmware. Also thanks to SD/Pacman and ex58 for letting me know.

ReUpload Intel ME 9.1 Consumer 1.5MB Firmware v9.1.37.1002 (EXTR --> RGN)



Thanks to Sylar76 for the clean/RGN latest 9.1 firmware.

@ error-id10t:

As seen at the Repository thread: The Type of each firmware can be Stock Region (RGN), Extracted Region (EXTR) or Update (UPD). RGN are provided by Intel, EXTR by SPI/BIOS images and UPD by Intel or FWUpdate.

Rev stands for Revision and it's the stepping of the PCH. Pretty much every publicly released (Production) PCH is at stepping D0 for PCH-H and C0 for PCH-LP. At MEA it's only mentioned when I know it's value due to the filename of the firmware, a changelog or similar. Unless Intel has released a new PCH stepping (very unlikely), it should still be D0 and C0 for H and LP respectively.

If you use FWUpdate, you don't need to change any settings as it uses Update (UPD) images and not the full Region (RGN or EXTR).
