Issue updating bios



I'm a happy owner of a old nuc D53427RKE wich I bought it second hand. 

I tried to update the BIOS from "RKPPT10H.86A.0017.2013.0425.1251" to the latest version, but shows "fwUpdateFullBuffer". 


I searched about it and I found that in the Version 40 (I have installed the 17) the buffer size changed and it's a mandatory step to update to the last one (57).


The intel website only allows to download the latest version and I can't found previous versions on the internet (and I'm afraid to download bios from strange sites).


Where can I find older versions to update the nuc?

Hello @cesarblancg 

Updating BIOS from version 0017 to 0057 is a big jump. Since the Management Engine (ME) was updated few times it was and probably was locked during your try to update BIOS. 

1. I would suggest to update BIOS using BIOS Recovery with the Yellow Jumper Removed:

1.1Prepare USB stick fully formatted to FAT32 with Bios File . Format your USB with Quick Format option unchecked. Do not format your USB in MAC (OS) or Linux machine. Use Windows.
1.2 Disconnect the power adapter and remove the bottom panel from your NUC.
1.3 Remove the Yellow Bios Security Jumper. (page 52 in Technical Product Specification)
1.4 Insert the USB with the file into rear USB slot.
1.5 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.
1.6 When bios recovery is completed, press and hold the Power Button to switch the power OFF, remove the power, adapter, the USB and replace the Security Jumper (pins 1-2) . Reinstall the bottom panel.
1.7 Power your NUC ON.

2. Once the NUC BIOS was recovered, update BIOS again using the F7 method and the same USB stick with the file. Now the update should be finished successfully and the ME should be updated.
