Ok friend,
Error 28 It could be bypassable using (Svl7 prr tool) !
We will try It, so download and unpack file and prepare an USB Stick following instructions !
It will be Dos Fat32 Bootable, then copy all files from modified folder into It and Boot from USB, so run Flash.bat to write Bios Mod into Eeprom :

I just tried this way, but was out of luck !
I hope now will go better, but if It don't work only chance is SPI Programmer !
Let me Know

no luck....

i think the problem is the sign of file.... if file is signed then the program sets eeprom writeenable if not there is an error....

because i've tried to flash a backup with the same tool.... but it fails....

for me we must concentrated on the origininal insydeflash program maybe there's an args to ''force'' write or something else .... intel FPT maybe works only on intel motherboards....

i want to try flashrom under linux.... but support says
Probing works (Winbond W25Q64, 8192 kB, SPI), but parts of the flash are problematic: descriptor is r/o (conforming to ICH reqs), ME region is locked

at last can u show me a cheap spi flasher?? thanks...

Extracted from service manual....

The function hotkey sequence Fn+Esc is used to enable the BIOS recovery process when
system is powered On during BIOS POST. If this function is enabled, the system will force the
BIOS to execute the boot block program.
To perform a BIOS recovery:
1. Shut down the BIOS failed-computer.
2. Connect the USB flash drive containing the Crisis Recovery disk files to the computer.
3. Press and hold the Fn+Esc keys, then press the power button .
The BIOS recovery process begins. When the process is complete the computer will
automatically reboot.
4. Disconnect the USB flash drive from the computer

BUT THE USB KEY SHOULD BE IN THIS WAY

1. Open the Notepad program and create a new file
   
   
2. Rename it in startup.nsh
   
   
3. Inside copy and paste this two lines:
   fs0:
   PFlash.efi /bb1 /silent /sv /sd bios.fd
   
   
4. Save this file as startup.nsh in the USB flash drive’s root directory
   
   
5. Decompress the Crisis Package Source** in the USB flash drive’s root directory
   In usb root directory we should be have 5 file and 1 folder
   EFI folder
   BIOS image file
   BIOS.cap
   PFlash.efi
   PFlashX86efi
   Startup.nsh
   

** Anyone have crisis disk??? if yes i can try to flash it....

Ok friend,
You have to look into your result file and see the Eeprom chip type in picture :

W25Q64BV

So your Programmer have to get this chip in Chips Compatibility List !

It seems good and is cheaper too !
