After a failed Jumper Reflash of the NUC Bios im hoping someone knows if it is even possible to successfully reflash the Winbond Flash without any special purpose encrypten/decryption tools from Intel.
I´ve got multiple .bio binaries for the NUC model, but rewriting the Flash with the TL866II Flasher does not help.
thx a lot
No. The .BIO files are compressed and encrypted and can only be read by the BIOS itself. You would need the image in .BIN form, but, due to security requirements, Intel does not (and will not) provide the BIOS in this form.
Further, when the BIOS is initially installed into the flash component in the factory, special tools are run that "brand" the BIOS for the particular board. This branding specifies the board's Serial Number, AA Number and other board-specific SMBIOS strings, MAC Address, etc. The tools to do this branding are not distributed outside of Intel. What this means is that you cannot (or at least should not) take the image from the flash on one unit and use it in another unit if both of these units are to be used subsequently.
When you say a failed jumper reflash occurred, what specifically do you mean? What happened?
Thank you for the info, i already expected something like that.
I did a update from 0051 to 0072 and at the Intel Management Engine and Error was thrown.
"Flashing Image for Intel Management Engine firmware ... FW Update Fail in GetLastStatus"
After that boot was no longer possible, no blue light, nothing.
51 to 72? That's a little far to be jumping in one operation.
You need to do two things, (1) clear CMOS and, if that wakes it up, (2) BIOS Recovery.
To clear CMOS, you need to remove the NUC's board from its case and unplug the battery for 15 minutes. Here is a video that shows you how to do this: https://www.youtube.com/watch?v=GzHzu475y8U (thank you Jason).
Once you have removed the board, unplugged the battery for 15 minutes and reinstalled the board, stop with the case still open. Now follow my process for doing a BIOS Recovery:
Hope this helps,
Thats what i meant with the jumper reset procedure, thats what produced the error and now the NUC has no post or leds anymore.
i assumed the ime firmware was written only partial and was hoping i could write directly to the winbond flash, but that seems to be impossible because i cant get a decrypted binary.
As i dont have the same nuc, i cant try a flash copy, so ill just just take my loss and move on;)
but thx a lot for the help!
