Latitude 10 ST2E won't start after BIOS update

Hi There,

I have Latitude 10 ST2E which I attempt to up date to the lattes BIOS. The BIOS updated went successfully but after the restart the tablet didn't even boot up. Now when I press the power button the power LED goes on for about a second and then goes off and nothing happens. I tried different combination to hard restart the tabled by holding down the volume buttons and then pressing the power button eventually I remove the main battery as well as the clock (CMOS) batter in hope to unbrick the tabled but no success so far. 

I think I identity the BIOS memory IC (W25Q16BV - 2MB flash memory) and I am able to desolder the chip and flash it with external programmer. The only problem I have is that I don't have the binary of the BIOS itself dell website supplies only the BIOS together with the BIOS flushing program which I can't use.

I would really appreciated if somebody can help me find binary file of the BIOS of this tabled.

Thanks in advance,
