No HDMI after BIOS update for NUC5PPYB

[gianarb]

Hello

I reached out a few weeks ago but I got distracted by other things.

https://community.intel.com/t5/Intel-NUCs/How-to-find-old-BIOS-version/m-p/1209238#M76473

I have a few NUC5PPYB all of them running BIOS v55. I updated two to v79 and they "stopped working".

It looks like an HDMI issue because netbooting works and I can serve Linux via IPXE and use it correctly.

I got a v55 of the BIOS and I tried many recovery procedures like the Jumper one for example nut I can't see the BIOS it means that I can't really follow any graphical-based installation.

Any suggestion? There is an unofficial or hacky solution I can try that uses Linux as the base OS?

Thanks

Hello Jose

Thank you for your help, a lot of this informations are in this previous post I made

https://community.intel.com/t5/Intel-NUCs/How-to-find-old-BIOS-version/m-p/1209238#M76473

But let me answer here:

1. I am not even able to run an operating system. When I power the board the BIOS does not gets visualized to my HDMI monitor. I know the bord reaches the netbooting because I see logs from my DHCP server from the board download a netbootable Linux OS. I installed Windows to an HD using another NUC and I tried to swap the hard drive to see if Windows was showing up but nothing. It does not.

2. Yes HDMI issue started when I updated 2 of my 10 NUCs from v55 to v79. I updated only 2 of them and both have this issue. The eight I left with version v55 are working just fine.

3. Those NUC do not have a case, and I am not sure how I get those value from. I see those:
removing sensitive information

4. I can't provide any report because I can't see anything via HDMI. 

In short, I think the boards are booting fine but I can't see any output via HDMI

Hi gianarb,

I would recommend that you try a BIOS recovery using the same PY0079.bio file via the Security Jumper method, you can find the instructions here: https://www.intel.com/content/www/us/en/support/articles/000005636/intel-nuc.html

If this procedure doesn't work, please reach out directly to our Intel Customer Support service to verify if warranty options are still available for this product  (we cannot process warranty requests over the community due to privacy regulations).

Here is how to contact us directly: https://www.intel.com/content/www/us/en/support/contact-support.html#@7 and make reference to case number 04920639.

Is there any particular reason why you are jumping from BIOS 55 to BIOS 79? Is it just to keep the systems up-to-date? The NUC5PPYH is already discontinued https://ark.intel.com/content/www/us/en/ark/products/87740/intel-nuc-kit-nuc5ppyh.html and we have limited resources available to support this product.

Hello

I have finally managed to hook the NUC to another monitor and I can see the BIOS!

So apparently the problem happens only on my DELL monitor.

Now that I see the BIOS I tried to downgrade it to 55 using the file +AlHill shared with me previously:

https://community.intel.com/t5/Intel-NUCs/How-to-find-old-BIOS-version/m-p/1206852/highlight/true#M76203

Apparently, the BIOS stays in the current version I can't downgrade, visually I don't see any error during the update process.

Any idea?

[n_scott_pearson]

In theory, you cannot downgrade through any BIOS release that includes security changes or a change to the ME firmware. So, why is it that you want to go back all the way from BIOS 78 to 55? That's an awfully long way...

Hello! There are a couple of reasons

My end goal is to have the 2 NUCs I updated working with my DELL monitor as the other 8 I didn't update. That's why I am looking for a downgrade.

The download center does not provide old versions of the BIOS, and 55 is the unique one I was able to find asking in this forum. I also can't identify from the CHANGELOG a good version I should downgrade to, so I got to the most obvious one.

[n_scott_pearson]

After looking closely and the BIOS Release Notes, I am not seeing any changes in the BIOS that cannot be reversed. Please try performing the downgrade again. If it fails, please detail exactly what you saw as you tried to follow the process.

[gianarb]

Ok I finally managed to track down an actual error.

I select "Update BIOS" from the boot menu and I select from a USB the BIOS v55 file.

I starts the update process:

Preparing image for Intel (R) Management Engine Framework ... [Done]

...

...

...

Preparing image for Graphic firmware... [done]

Flashing image for Intel (R) Management Engine firmare... [done]

Flashing image for backup recovery block firmare... [failed!]

..(cant'read)..nsh information: (0x800000000000007, 0)

And that's it. The 

Flashing image for backup recovery block firmare...

Takes good 2 minutes it stays at 20% until it turns to done.

Thanks

Any feedback for me?! 

Thanks!! I am happy to try a different BIOS version of somebody can point me to a good one

[n_scott_pearson]

The process you used cannot be used to downgrade the firmware. The only way to downgrade the firmware is via the BIOS Recovery process. This is documented here: Intel NUC BIOS Update and Recovery Instructions. I suggest you start with the section titled BIOS Recovery by Power Button Menu.

Hello gianarb, 

Do you have an update on this by any chance? 

As previously mentioned, the recommended step to downgrade the BIOS version is to make a BIOS recovery: https://www.intel.com/content/www/us/en/support/articles/000005636/intel-nuc.html  

You should try the "BIOS Recovery by Security Jumper" or the "BIOS Recovery by Power Button Menu" options.  

Please let us know if you could complete this procedure.

Hello

I tried but unfortunately when I press F7 from the "Power Button Menu" I don't see any log and the NUC holds a black screen until I restart it (I even waiting 30 minutes). The BIOS is still the version I have and not the one I desire. Tomorrow I will wipe the USB and I am going to try again.

Do I have a way to verify that bios file PY0055.bio I have is good?

[Sebastian_M_Intel]

Hello gianarb,   

Thanks for the response. 

Please remember that the BIOS recovery was the last resource to try with this issue. 

This Intel® NUC is discontinued, so Intel Customer Service no longer supports inquiries for it. 

I recommend you to contact us and refer to this thread for warranty replacement options https://www.intel.com/content/www/us/en/support/contact-support.html#@7

Just to Chime in, I'm having the exact same issue as posted above.  The 0079 Bios shouldn't be listed for the Nuc if it won't allow any changes to the bios (I can't boot from USB to install a new OS)
