Bios update on DC53427HYE fails

I'm trying to update my DC53427HYE to BIOS version 49 via the F7 procedure. The updater recognizes my USB drive and the RK0049.bio file on that drive but after confirmation the system immediately reboots instead of starting the update. After the reboot the BIOS Event Log shows the message "Flash Update Failed (21)". Does anyone know the meaning of this error 21?

JosF: Thank you very much for contacting the Intel® NUC communities. We are sorry to hear the BIOS update did not work properly.

 

 

In regard to your inquiry, the error 21 means that the NUC is initializing a chipset component:

Please make sure the USB device you are using is formatted in FAT32 and the .BIO file is the only file on it. If the problem persists when using the F7 method we can always try a BIOS recovery:

Any further questions, please let me know.

Yea, let me state this more categorically:

  • In the BIOS, support is only provided for the FAT32 file system. Despite claims to the contrary (and no, I am not going to debate it), VFAT, exFAT and other similar file systems are *not* 100% compatible with FAT32. You should not attempt to use them, period.

  • If you purchased a USB flash stick that was initialized on a Linux or MACOS system (as many of them seem to be), you may have to reinitialize this stick before you can use it successfully with the BIOS. To do so, reformat the stick on a Windows-based PC, using the FAT32 file system, with the Quick option disabled. Actually, I recommend that you *always* do this, at least once, with any new USB flash stick you purchase (sorry for how long this operation can take with slower USB 2.0 flash sticks).

Hope this helps,

Thanks fpr your replies. I reformatted the USB stick to a FAT32 file system and tried to flash the BIOS again but unfortunately without succes, The updater recognizes my USB drive and the RK0049.bio file on that drive again, but now after confirmation the power led starts to blink, the fan starts to run and the screen remains blank. After a reboot the BIOS log now contains the message "Flash Update Failed (32)". (This error code is not listed in the POST codes.) Any ideas what to try next? I'm not confident that when the F7 update fails the recovery procedure will function.

Hello Jos,

Try to recover your BIOS from Power Button Menu: https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html BIOS Recovery Update Instructions for Intel® NUC .

In order to boot into Power Button Menu, you should release the Power Button soon as the power led changes color from blue to amber. NUC will reboot into Power Button Menu. With the USB containing the latest bios file, press F4 and the recovery shall start.

If this doesn't work, try again using the jumper-based Recovery Method. In NUCs this old, I am not sure that the hardware changes necessary to support the Power Button Menu-based Recovery Method are present.

Thanks for your support. I'll try this when I have the opportunity again.
