1st Why are you trying to upgrade BIOS? Is to solve a problem? Or just because you want to?
2nd There are 4 different methods of upgrading the BIOS- The one you using is probably the less recommended.
I would suggest to upgrade BIOS by ISO image or by Recovery mode.
Instructions are found on:
I personbally would recommend the BIOS recovery method via a USB pendrive, just remember to remove all other media a usb devices when you do it. You won't even need the keyboard or mouse
If you have any security software on the machine , when you use the express update you have to do it off line with all security software disabled.
i looked around i saw a new bios update for me board so i though might as well,
so i thought id try the express way.
Security software used on my pc is zonealarm free firewall, avg free, malwarebytes anti-malware, keyscrambler and zemana antikeylogger.
havnt done anything else today been very busy.
At me the same problem.
Current version 3592, I update on last 4131.
As it is known, INTEL recommends some methods of update of a BIOS. And so it has not turned out to update a BIOS for me any method.
On the screen:
Preparing Image for recovery firmware... [done]
Preparing Image for main firmware... [failed!] (4992 byte overflow)
Flash Update Falied!
Technical Information: (0x8000000b, 1202)
What to do?
