Upgrading an ASUS Z87 PLUS motherboard firmware

I needed to upgrade a firmware (in fact, it should have been done a long time ago). The steps goes as follow:

1. Find a firmware: (https://www.asus.com/Motherboards/Z87PLUS/HelpDesk_Download/)
   http://dlcdnet.asus.com/pub/ASUS/mb/LGA1150/Z87-PLUS/Z87-PLUS-ASUS-2103.zip
2. Unpack it and localize Z87-PLUS-ASUS-2103.CAP (or some other older version Z87-PLUS-ASUS-2004.CAP or Z87-PLUS-ASUS-1802.CAP)
3. Prepare a FAT flash device
4. Copy the firmware *.CAP file to flash root directory and rename to: Z87PL.CAP
5. Plug flash into the 'flashback' USB port at the back of PC (it's next to ethernet with a green border around)
6. Press flashback button on a motherboard, it's below a power plug, labeled as "BIOS_FLBK"

The FLBK_LED should start blinking (if it stops blinking means it cannot read firmware or the file is broken). It will take few minutes. DONE.


BTW. It sucks that Asus just doesn't say what should be the name of a firmware file. They could just use FIRMWARE.CAP and it would be fine. There are other ways of protecting people from themselves than encoding the model in a file name.
