Hi friend,
I think You went to 2.28 from 1.xx version so You passed into a UEFI version where You need GPT partition to Boot so have Reinstall Windows !!!
To Downgrade your Bios You need a Recovery Bios 1.xx version !
I will upload here quickly.

Here You go :

https://www.sendspace.com/file/3fpwup

Format an USB as Fat32 and use Recovery Mode :

- Shutdown the netbook (notebook)
- Remove all peripheral devices
- Remove battery, Remove AC power cord
- Press and hold the power button for 10 seconds (battery and AC power still out), then release
- Put the USB Memory Stick in the USB port
- Hold "Fn" + "Esc" and plug the AC power cord in
- Now press the power button (whilst still holding Fn + Esc).
Wait until the fan will run, then release "Fn" + "Esc" keys
- The fan will run for about 2-10 minutes and the USB drive activity LED will blink
- I think the netbook rebooted automatically. If it doesn't, unplug the AC power cord once the fan has turned off

The bios should be updated with the modified BIOS, and boot as per normal.

Let me know

We can only force to flash It by FPT Intel Tool, I think your Eeprom is write Protected now !
Can You do a Bios Examine using this tool, run It as Administrator and upload here the result file :

I will give a look and will make a Generalized Bios Region version to reflash by FPT.
Let me know

Hi friend,

I have done a lot of time ago the same thing and It seems that using FPT didn't work, but renamed the file as Recovery Bios and using Recovery Procedure was going well !

So here your Bios Original version 1.15 FPT here :

http://rghost.net/57297150

Then the Recovery Name is VAG70X64.fd, I want to know how Amerco done as He disappered from scene and I did can not to ask anymore !

To use as Recovery File rename It as VAG70X64.fd, prepare an USB Fat32 Formatted, copy that file into and reboot from USB using this procedure :

- Performing the emergency flash:

- Shutdown the netbook (notebook)
- Remove all peripheral devices
- Remove battery, Remove AC power cord
- Press and hold the power button for 10 seconds (battery and AC power still out), then release
- Put the USB Memory Stick in the USB port
- Hold "Fn" + "Esc" and plug the AC power cord in
- Now press the power button (whilst still holding Fn + Esc).
Wait until the fan will run, then release "Fn" + "Esc" keys
- The fan will run for about 2-10 minutes and the USB drive activity LED will blink
- I think the netbook rebooted automatically. If it doesn't, unplug the AC power cord once the fan has turned off

The bios should be updated with the modified BIOS, and boot as per normal.

Don't forget to disable SecureFlash into Bios before use FPT or Recovery !!!
