- WOW, this will be long jump over 19 BIOS versions (since you didn't mentioned this in your post, I presume that you have have NUC7ixBNx). Since you are going to make such big update, I suggest that the best way to do this, is with BIOS Secure Jumper Removed method:
- Prepare USB stick fully formatted to FAT32 with Bios file BN0081.bio . Format your USB with Quick Format option unchecked. Do not format your USB in MAC (OS) or Linux machine. Use Windows.
- Disconnect the power adapter and remove the bottom panel from your NUC.
- Remove the Yellow Bios Security Jumper. (page 59 in Technical Product Specification ) .
- Insert the USB with the BE0081.bio file into USB slot.
- 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.
- When bios recovery is completed, press and hold the Power Button to switch the power OFF, remove the power adapter and replace the Security Jumper (pins 1-2) . Reinstall the bottom panel.
- Power your NUC ON.
- Enter Bios setting by pressing F2 during boot process.
- Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.
Yes, my NUC is NUC7i7BNH sa J31153-308 and mother board is NUC7i7BNB version J1145-307.
There is a note in BIOS Recovery by Security Jumper procedures saying:
Note: BIOS recovery using the BIOS security jumper will clear Trusted Platform Module (TPM) keys, Intel Platform Trust Technology (Intel r PTT, and High-bandwidth Digital Content Protection (HDCP) keys. These keys will not be restored after BIOS recovery.
Anything else I need to worry about? Also, what is the chance I will turn my NUC into a brick?
- You are asking question that I can't answer. I've updated BIOS many times in different NUCs. Never bricked one. However, I'm performing update always when new BIOS is released. As I've mentioned, your update from 0052 to 0081 is a long jump. The recovery method with the Security Jumper removed is the safest method in this case. In my opinion working with so old Bios can be more problematic and unsafe. I can only say that I would update this BIOS.
- If your drive is encrypted with Bitlocker, I would remove this encryption for this update. To be on safe site. Use USB stick 8 GB - 32 GB, fully formatted in Windows to FAT32. Insert this USB in rear USB port and follow my instruction.
Wish you good luck
Thanks for the information and guidance. Yesterday I turned off BitLocker on my C: drive and today I was going to shop for the USB stick so I could try your update procedure.
I booted up my NUC this morning and Intel Driver and support assistant started and updated my BIOS successfully! It looks like the M.2 card being encrypted was somehow causing unsuccessful post attempts during boot which was not allowing my BIOS to update.
All is good now. Thanks.
