Its another Hardware! Win7 Vaio S = legacy BIOS, Win8 Vaio S = (U)EFI with security flash.

Hi, you could do it with a hardware flasher/programmer. First buy a hardware flasher: e.g. a UM232H with FTDI chip FT232H this one. Then download flashrom (or fpt). Now you have to open your Laptop and look for your BIOS (its a flash IC) and desolder it. Then search for the flash ic datasheet and look for pin layout. Now you have to solder the SPI interface to your flasher. Then power it up with a external power supply and backup all the flash content (or bios section). Maybe you can still read the serial number etc, if this has not been damaged during update and put this informations into a new bios image and simply flash it back. I know its VERY difficult, but maybe your last chance if everything else didnt work!

Here is the Service Manual for SVS131 from 2013: http://www.docs.sony.com/release/MDSM/989095201_sm.pdf 2012 http://www.docs.sony.com/release/MDSM/989092601_sm.pdf And few pictures from my disassembled SVS1312H3ES Windows 8 Model. Images may be helpful for anyone Images.rar (high res images) I disassembled my netbook (you can see it on the pics) to desolder my BIOS flash IC (on the last image right under the battery). It's a Macronix "MX25L6406 EM2I-12G" 8pin SOIC. @ the Bios menu screen (or with CPU-Z) it says its a MX25L6405, the old and discontinued version from MX, because the new chip have the same SPI ID! After desoldering, I've read the content (64Mbit = 8MByte) with the tool flashrom.exe (Win32 v0.9.6.1 - r1671 specially compiled for me and my chip ). I've sent the backup to svl7 to unlock the OC function for me.

Ah, I read your thread for flashing UEFI bios with this damn secure boot thing. It is possible on my Notebook or do I have to "direct flash with SPI hardware programmer"?

What happens if I flash the bios with an external Programmer (Olimex JTAG Flasher -> SPI flash) (flashrom software)? I could look for the bios chip name and if this chip has a SPI seriell interface. I've done this with my bios on my Gigabyte PC mainboard, but this bios was a normal bios chip.

Will there ever be a way to mod the bios or to overclock via hardware mod with my SVS1312H3ES?
