Bios Mods -The Best BIOS Update and Modification Source

Hello, I have the following problem, update the BIOS of my Acer E5-553-1786, but I had a problem and it could not be updated well and now it does not start, the ACER icon is not shown, it is like brick I have seen in some forums that there is a method of recovering the BIOS through a USB memory and the file ZABA.fd.
I did the procedure for the recovery of the bios:
1. Format the USB memory in FAT32 format
2. I put the file ZABA.fd in the USB memory
3. I turn on my laptop with FN + ESC, the power LED flashes but the USB  LED don´t flash.

However nothing happens, in what I have read, they say that the ZABA.fd file must be renamed correctly so that the BIOS recovery can be done but I don't know how to get the correct name to continue the procedure.

Can you tell me if it is the right procedure?
Is there another method?
I need something?

Sorry if my English is poor. 

Thanks for your help. 

You have to find the initial bios update from acer and unpack the .exe or whatever it is and then continue unpack till you find a .fd file. Usually, the name is in capitals and it is the one that is on the motherboard...I think the motherboard model...
