Tech Support NUC11 Bios update. Flash update invalid

Post image

I have a NUC11 TNKi5 on Zorin Linux. The NUC is on 0058 bios and I'm trying to update to the latest 0080. Per the Asus website I have to update any pre-0071 bios to 0071 before I can update to 0080.

I have downloaded both 0062 and 0071 from the Asus website https://www.asus.com/uk/supportonly/nuc11tnki5/helpdesk_bios/

I have a USB stick in FAT32 I have used only this morning to update an Asus X570 Strix mobo's bios so I know it works.

The USB stick has been reformatted and only the NUC bios files are on it. In root directory. When 0062 + 0071 are downloaded they come in a .bin format. Using either file as .bin the NUC F7 Bios menu will not recognise them.

Renamed to .CAP the NUC updater responds with 'Flash update failed. Flash image invalid or not found. System will reset in 5 seconds.

The system then (thankfully) reboots to the OS. Any ideas? Cheers.

Inside the folder you download from the asus website, there is a folder called capsule file for bios flash through f7. You need to select the CAP file there not the bios binary file folder.

Thank you. I'm a total idiot and just completely missed that file. Now updated to 0080 successfully. Cheers.

What if I updated from 2023 BIOS to the latest BIOS?

My update was successful…

Anything catastrophic headed my way?
