Hi friend,
the Bios extracted from chip is not usable to reflash and I have to looking for your
Significant Data to copy into original.
I have extracted from Original Bios the Region_Bios and I think It will be the right he file for You (as I compared with a Bios Backup I got and It's the same).
So now You can try to flash a file and look if your laptop starts then we can reflash again the file with your data into !
Here there is a file to write by SPI Programmer into Bios Chip :

Let me know

For your Bios extracted (readout.bin) to look your data You have to find an ID = _FVH from here there are your laptop data like Serial, UUID, etc.

Acer Aspire E1-531 - G - E1-571 - V3-531 - G - V3-571 - G - TM-P253-E - M - PB EN TE11HC - PB EN TV44HC - GWNE56R
Same MoBo = same Bios

Which version is your Bricked Bios ?
I am afraid that You have to re-write EC chip too !
Have You checked if You got a second chip for Bios ?
Or You have backuped EC Chip ?
Can You post the Chip name ?
Let me know
Regards
