In case someone does a google search and ends up here: I was able to flash firmware of my Vaio Z VGN-Z555DN laptop w/OCZ Agility SSD firmware to 1.4 using this convoluted procedure.
First you must flash laptop BIOS to R2168M3 (if using Vaio series 5); prior version might work too. Then use the hack to enable advanced menu in the BIOS – search for “Feature Enable” and VT enable on Vaio Z; you’ll need a USB stick with EFI/BOOT etc. Then after flash you will be able to enter BIOS (press F2 during boot) and enter advanced menu and change SATA mode to IDE. Now use CD or USB to flash firmware to 1.4. After that, you can again reflash R2170M3 (needed for graphics drivers in Windows 7). You will now again be in AHCI mode and you should enter BIOS again to enable VT as well if you wish. This downflashing of BIOS is needed because version R2170M3 removes advanced menu so it’s not possible to change AHCI to IDE.
This is still easier and faster than disassembling the laptop.

My friend and I were recently discussing about technology, and how integrated it has become to our daily lives. Reading this post makes me think back to that discussion we had, and just how inseparable from electronics we have all become.
I don’t mean this in a bad way, of course! Ethical concerns aside… I just hope that as technology further innovates, the possibility of downloading our memories onto a digital medium becomes a true reality. It’s a fantasy that I dream about almost every day.
