Need help to unbrick ACER Aspire ES1-131-C4UB

[z2168235]

My ACER Aspire ES1-131-C4UB initially having problem with keyboard and mouse pad. The keyboard was working in BIOS mode but not working in OS mode. Thinking maybe updating the BIOS from version 1.1 to 1.24 might help solving the problem. It was succesfully updated to 100% but after auto reset it does not boot anymore, the screen just black.

I got the BIOS from ACER website https://global-download.acer.com/GDFiles...ER&SC=PA_6

I unzip the files and even unzip the ".exe" but somehow unable to fine ".fd" file. Can anyone help me on this?

BiosImageProcx64.dll
Ding.wav
FlsHook.exe
FlsHookDll.dll
FWUpdLcl.exe
H2OFFT-Wx64.exe
iscflashx64.dll
iscflashx64.sys
platform.ini
xerces-c_2_7.dll

Thank you
Regards
