NUC8i7HVK BIOS update problems

Hello, I just purchased a NUC8i7HVK Kit. I have installed Windows 10 Professional, and noticed that the BIOS Version is quite old, at:

BIOS Version/Date Intel Corp. HNKBLi70.86A.0029.2018.0222.1606, 2/22/2018

This version is dated enough that I cannot even locate release notes for it. I also noticed the first release I could find, https://downloadmirror.intel.com/27724/eng/HN_0034_ReleaseNotes.pdf 0034, dates from 3/29/2018 and is stated as an "Initial pre-production BIOS release". I https://downloadcenter.intel.com/download/27747/NUCs-BIOS-Update-HNKBLi70-86A-?product=129705 downloaded the latest version, 0037 from 4/22/2018. Unfortunately, none of the BIOS update methods I have tried work. I am not new to various methods of BIOS update, having done system builds for over 25 years. That leaves me especially frustrated in this scenario. I'd greatly appreciate any guidance the community has to offer.

 

Methods attempted:

Method: https://www.intel.com/content/www/us/en/support/articles/000005827/mini-pcs.html Express BIOS Update Instructions for Intel® NUC

Outcome: Failed - new BIOS version selected, reboot to no observable activity

Notes: I am able to follow the linked instructions through Step 5, where I click Restart and Install BIOS button. Immediately after clicking, the NUC reboots to no video signal. Sometimes, there is a second reboot in this cycle. After a couple minutes, the NUC reboots itself into Windows stating that the BIOS update has failed. There is a link here to a readme file which, to my reading, contains no relevant troubleshooting information.

Method: https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html F7 BIOS Update Instructions for Intel® NUC

Outcome: Failed - new BIOS version selected, reboot to no observable activity

Notes: I am able to follow the linked instructions through Step 8, where I select the .bio file located on the USB drive. Immediately after selection, the NUC reboots and there is no video signal. I wait for 5+ minutes with no response. I have to hard power down the NUC, at which point it boots to Windows still at the old BIOS version.

Method: https://www.intel.com/content/www/us/en/support/articles/000006030/mini-pcs.html Power Button Menu BIOS Update Instructions for Intel® NUC

Outcome: Failed - new BIOS version selected, reboot to no observable activity

Notes: I am able to follow the linked instructions through Step 5, where I select F4 for recovery or F7 for normal update. After selecting the new BIOS version, both methods yield an immediate reboot to no video signal. Again, after waiting a few minutes I must hard power cycle the NUC to reboot into Windows to see the old BIOS version still installed.

Method: https://www.intel.com/content/www/us/en/support/articles/000006640/mini-pcs.html iFlash BIOS Update Instructions for Intel® NUC

Outcome: Failed - could not boot to USB

Notes: I created a USB boot disk using http://communities.intel.com/ Rufus and the correct parameters for a FreeDOS based disk. I could not select the MS-DOS option what was available in various https://www.qualityology.com/tech/create-a-bootable-ms-dos-freedos-usb-drive/http:// tutorials. Using the F10 boot options on power-up, the USB drive is not an option. In BIOS I've ensure that USB Boot is selected, Secure Boot is deselected, and UEFI USB is first in boot priority.

Ok, I hope that's enough for now. I'm attaching a dump of my System Information for reference.

You didn't try yet Bios Recovery with Security Jumper removed: https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html BIOS Recovery Update Instructions for Intel® NUC

1.Prepare USB stick fully formatted to FAT32 with Bios file HN0037.bio https://downloadcenter.intel.com/download/27747/NUCs-BIOS-Update-HNKBLi70-86A-?product=126143 Download BIOS Update [HNKBLi70.86A] . Format your USB with Quick Format option unchecked. Do not format your USB in MAC (OS) or Linux machine. Use Windows.

2. Disconnect the power adapter and remove the bottom cover from your NUC.

3. Remove the yellow security jumper (see Product Technical Spec, para. 2.2.3.3, page 41 ) and close the bottom cover. https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p...

4. Insert the USB with the HN0037.bio file.

5. Reconnect the power adapter and power ON the NUC. Wait 30 sec - 2min. The Recovery process will start automatically and will end after 2 -5 minutes.

6. When bios recovery completed, switch the power OFF, remove the power adapter and replace the Security Jumper (pins 1-2)

7. Power your NUC ON.

Hope this will work

lw1948 - I followed the directions for Bios Recovery with Security Jumper removed. Unfortunately, the outcome is the same in that I'm on the original BIOS version. My observations during this process were:

  • Upon initial boot after jumper removal, a screen stating such appeared, offering a number of options. I chose F4 for BIOS recovery.
  • After my choice, two reboots immediately occurred.
  • Approximately two minutes later, another reboot occurred.
  • Approximately another two minutes later, another reboot occurred.
  • Approximately 30 seconds later, another reboot occurred.
  • At that point, no further reboots occurred, so I waited another five minutes.
  • I powered off the machine, replaced the security jumper and rebooted into the same BIOS version as before.

Hello MitralOverflow ,

During recovery try with security jumper removed, NUC instead of starting recovery, you have seen menu with different item. I assume that this was Configuration Menu (similar to image attached). To additional explanation see the last item in Table 14 on page 42 of the Product Technical Specification: https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... . Your problem may that your USB is not correctly formatted (was used in Linux) and therefore a valid Bios file is not found. Try to use other USB (fully formatted to FAT32). Or, try to fully reformat using SD Formatter : https://www.sdcard.org/downloads/formatter_4/ SD Memory Card Formatter - SD Association . This tool is good for USB memory as well. After preparing new USB you can try to recover using any method - pressing F4 from Power Menu or Security Jumper method.

lw1948 - Yes, I was seeing the Configuration Menu when I had the Security Jumper removed. I reformatted two different USB drives using the SD Card Formatter software linked in your post. Both sticks are now fully formatted to FAT. I placed HN0037.bio as the only file on the USB drives.

I decided to try the F7 BIOS update method, and here were my observations trying either of the USB drives:

  • After file selection, the NUC rebooted immediately to no video after file selection
  • No further self-reboots observed
  • Power cycled, and the NUC immediately self-rebooted after power-on, again to no video
  • Power cycled again, and the NUC now boots to Windows on original BIOS version

I then tried the Security Jumper method. I was not presented with the Configuration Menu, which was good, however I observed this:

  • Booted into Intel NUC welcome screen with "Setup" and "BBS" in boxes at the top right.
  • Stuck there for 10 minutes
  • I turned the NUC off with a quick power button press
  • At this point it was stuck in a reboot loop, with each boot cycle taking around 1 minute
  • Hard power down, replaced security jumper, and rebooted to Windows on original BIOS version

Again I think it is worth noting that, the above mentioned welcome screen aside, zero video feedback has been provided using any of these update methods. Based on my own reading and screenshots of the various methods, I should see progress indicators, correct?

Hello MitralOverflow ,

Booting into Configuration Menu, having USB with .bio file inserted brings me to conclusion that for some reason the bios file is not detected after powering ON the NUC. If the bios file is detected during power OB, the NUC shall start the recovery without booting into Configuration Menu. And yes, when bios recovery starts, you will see screen showing progress (see the attached image)

- Are your USB port OK?

- Do you have USB legacy and USB ports enabled (see the attached image)?

- Is your bios set to default settings (F9) or bios setting are customized?

lw1948 - For clarity, the last time I booted with the Security Jumper removed, the NUC did not display the Configuration Menu. Instead, it displayed a NUC welcome screen with "Setup" and "BBS" at the top right. See my notes in the second section of my last post for my full observations when attempting the Security Jumper method.

"Are your USB port OK?"

As far as I know, yes. I have had no problems with ports not recognizing devices such as keyboard, mice, and USB drives. I successfully installed Windows 10 on the same USB port I am using for BIOS updates. Per the https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... Technical Product Specification, Page 34, Section 2.2.1, Table 10 - I am using USB Port D, "Front USB Port USB 3.1 Gen 2". Are there some USB port diagnostics you recommend I run?

"Do you have USB legacy and USB ports enabled (see the attached image)?"

Yes, my Advanced > Devices > USB screen looks exactly the same as your attached image (see USBPorts.jpg).

"Is your bios set to default settings (F9) or bios setting are customized?"

My BIOS settings are at default with the following exception (see SecureBoot.jpg):

  • Advanced > Boot > Secure Boot > Secure Boot Config > Secure Boot = unchecked

lw1948 - Also of potential note, when I first booted the NUC after the last attempt to use the Security Jumper method, before fully booting into Windows I received a blue screen with the error: SYSTEM_PTE_MISUSE

The screen also stated that Windows would automatically reboot. The reboot occurred shortly after, and Windows 10 is currently operating without issue.

Hello MitralOverflow

Looking on the attached SecureBoot.jpg I can see that although the Secure Boot is disabled, still I can see that Platform Key is installed. Could be that this key is preventing from you Bios update? I would like to see Intel personal advise about this. I have not experience to dill with TPM keys. I thing if you change the Secure Boot Mode from Standard to Custom, you can take control of the TPM keys?

This is Windows error, probably caused by some corruption in registry, but could be result of error in RAM also.

lw1948 - I played with the options on the Secure Boot Config screen (see SecureBootConfigTest.bmp). It appears I would need to check Secure Boot and Clear Secure Boot Data to clear out the current keys & databases and enable Custom mode. I'm not sure if this is advisable, so further assistance from Intel or someone more familiar with this area would be much appreciated.

MitralOverflow , I agree that waiting for further assistance before changing the TPM data is good idea, however I think, Intel will be On Line only on Monday. In the meantime you can uncheck the box near Intel Platform Trust Technology in Advanced->Security->Security Features (see the attached image). This suppose not change the TPM, but only disable it. After disabling this you can try to update bios again.

lw1948 - I tried unchecking the Intel Platform Trust Technology box and then used the F7 BIOS update method. Unfortunately, the NUC rebooted twice in quick succession, then booted directly into Windows. I guess feedback from Intel would be required at this time.

I have the same issue. I am not able to update my NUC8i7HVK with a new bios, I have tried this several times.

Clearing the Secure Boot data should not have any effect on whether you can flash or not. You could try it just to be sure.

1. Enable Secure Boot and check "Clear Secure Boot Data". Save and exit.

2. Reboot back into the BIOS. Then check "Install Intel Platform Key" and "Force Secure Boot Defaults". Save and exit again.

3. Enter the BIOS again, uncheck "Secure Boot" to disable the feature. Save and exit again and try F7 flashing again.

A friend told me to try underclocking the memory to 2133MHz or 2400MHz. He saw the same issue on his HVK and when he did this, it was able to flash fine. Also, use only 1 DIMM.

MrMitch - Success! I installed only one DIMM, then set my memory settings as follows:

Advanced > Performance > Memory > General Settings

Memory Profiles - Manual - User Defined

Memory Multiplier - 18 (original value 24)

Save changes and Reboot

The multiplier change took my Memory Speed from 3200 Mhz to 2400 Mhz.

I then performed the F7 BIOS update method and finally received the on-screen feedback and confirmation I was looking for. BIOS and Windows System Information both report version 0037 is installed.

After BIOS update, I went back into Memory settings and changed them to defaults as follows:

Advanced > Performance > Memory > General Settings

Memory Profiles - Manual - Automatic

Memory Multiplier - (no longer user definable)

Save changes and Reboot

You were correct, the Secure Boot changes made no difference. Either way, I ended up re-enabling Secure Boot by following your steps 1 and 2.

Thanks so much for your help!

Thank you MitralOverflow for letting us know what worked!

I'm going to check with the engineers on why this is happening.
