BIOS downgrade

[jmmantel]

hello, after a bios update from 57 to 59 version, on a NUC7PJYH, it is no more possible to use any linux partitions. the downgrade is not allowed by the usual ways. might a silent jumper downgrade work in a similar case? thank you in advance.

Hello jmmantel,

Thank you for posting on the Intel® communities.   

In this case, I would like to let you know that for security reasons the system (NUC itself) does not allow a BIOS downgrade and this is to avoid damages to the unit (software and hardware). 

Try to force a BIOS downgrade can end up with permanent damage to the NUC and this could not have a solution and/o fix, that why I do not recommend you to try it.

Best regards,

thank you, deivid, for your reply. but what could i do if the linux systems, and all systems on live-usb keys, cannot be reached since the bios update? it seems that it is a bios bug in the bios last version, which is no more available on the download intel pages. the 57 version worked fine. but the problem occured in the 58 and 59 versions. here is a post on this topic.

Hi @jmmantel
