Hi all, I need to do a BIOS dowgrade my Dell 1545 A14 to A13 version, I searched information about how to do it but I get an error at the time of the downgrade, what I did was:

1) Create a bootable usb boot

2) Set the BIOS file to downgrade, here is 1545A13.exe

3) Restart the computer and press f12

4) Choose boot from USB

5) Run the file 1545A13.exe using / forceit or / forcetype.

The file runs but get an error that says "ERROR. BIOS update canceled by the user"

This is a picture of the mistake so well understood.

The Computrace is enabled and does not allow me to disable it in the BIOS, do not know if this will have anything to do, but attached a picture.

The error comes automatically because I did not press any keys. I would like to know what is this and how do I do to downgrade my BIOS since I'm doing everything correctly and I need to go back to one or more earlier. regards
