I am sorry you are having this problem but let me help you.
I see you have an old BIOS version and you are trying to update to the latest one and that is what the problem could be. Jumping 6 BIOS versions may affect your system since every single update contains a lot of fixes.
I recommend you going one by one from the 0122 to 0149. The best way is the one you are using (F7) so let’s keep that method but try installing the 0129 and so on.
Thank you for the fast response.
I have just tried your suggestion. Unfortunately, I get exactly the same response when using 0129 instead ( The "updating to revision"-line is of course changed to reflect that the 0129 version has been identified).
I have tried the iflash method also (using freeDOS on a USB stick) - and also tested this way again with the 0129 version. It still fails...
It think that the NUC BIOS could crashed since the transition BIOS was not installed. As you say, the Iflash method is the best one but at this point, I think that you need to try a BIOS Recovery process.
Try the version you had installed before and do the steps mentioned here:
If issue persists, I recommend you contacting your local support or contact us at this link:
The problem turned out to be a PCI card (SATA expansion from Delock). Apparently, the card somehow prevents flashing of the bios. I tried to remove the card from the board and then I had no problems flashing the bios - even jumping to 0149 straight away was a success!
