Notebook Model: China Brand HASEE K620C, which is called WS or TWJ by Quanta (an OEM )

BIOS:Insyde

CPU: i7 4700

Original BIOS operating:

The Original BIOS(6.6MB) cannot be loaded and modified by ezh2o2 and PhoenixTool tools.

Method 1

Result: Flash succeeds.

Method 2

Rename "TWSP232.86" to "TWSX64.FD" and put it onto a FAT32 USB Driver. Shutdown the computer, plug in the USB Driver, install the battery, then press WIN+B? The screen will be blank for 2 minutes.

Result: Flash succeeds.

Back-up than flash:

Using FPT tools Back-up the Original BIOS, export a twxxx.bin(4.5MB) bin file, it CAN modified by ezh2o2 and PhoenixTool tools but CANNOT be flash.

Method 1

Prompt:

Error This ROM file size is incorrect

Error:ROM size :480000 Current BIOS size:600000

Method 2

Reboot error, the screen still black and the flash dosn.t work. After a few minutes, it forcibly shutdown and BIOS never be flashed.

Skip Original BIOS's Header & Footer by WinHex and export a 666.bin(6MB) bin file, I modified and the Header & Footer back. Renamed xman.fd.

DOS:

FPT -F BIOSNAME.BIN -BIOS

Prompt:
