Aspire E5-573G BIOS

karatekidmonkey · July 2015

Is it possible for me to get a download of a previous version of the BIOS for the ACER ASPIRE E5-573G? I want to get 1.09 back because the Acer support guy told me to upgrade to 1.13, and it didn't fix anything besides making it more difficult for me to install Linux.

Thanks

I figured out how to XXXXXXXXX the bios.

Go to: http://us.acer.com/ac/en/US/content/drivers

Search by Product Model:

Aspire E5-573G

Select the right OS and download a bios. In my case I downloaded 1.15.

Run the ZRT_115.exe.

It will fail.

But before you close the installer, go to XXXXXXXXXXXX

Search for a folder (random letters).tmp

XXXXXXXXXXX

In that copied folder, edit the platform.ini file.

The VersionFormat value now has 'XXXX' instead of 'XXXXXX'.

This will ignore the fact that 1.25 -> 1.15 is a downgrade.

Prepare for a reboot. I.E. close unnecessary applications. Because it'll happen automatically after running the installer.

XXXXXXXX

Upon reboot, you'll see a bios installing progress bar.

After that is done, press F2 during startup to get to bios. The version should now be 1.15.

At this point I set a password, turned off UEFI, and swapped my hard drive out for a fresh SSD. Ubuntu finally installed.

THIS IS NOT AN EXACT ANSWER TO YOUR QUESTION. THIS IS FOR DOWNGRADING BIOS FROM 1.25 TO 1.15. JUST TO HELP YOU OUT AS MUCH AS I CAN, I AM SAYING THIS TO YOU NOW. WORK AROUND SOMETHING SIMILAR TO THIS AND I AM PRETTY SURE YOU CAN DO IT. ALL THE BEST! YOU WILL DO IT.

Okay, that answer absolutely XXXXXX.

1) I'M NOT USING THE 1.25 BIOS!!!!! Do you not see the post date? The 1.25 BIOS didn't exist at that time!

2) I can't extract the BIOS installer from that directory! My computer reboots as soon as I hit start flash, and before it starts up it flashes the BIOS.

3) This is fixed, I made myself a nice custom BIOS which works great.

Was able to change my bios back but windows update automatically updates it to the new version on restart. How can this be prevented. Acer E5-553G-1986

hi

what excat i must edit in platform.ini file ? if i want to DG bios from 1.13 to 1.11 or flash same version?

Lord_Corvin · May 2019

There are comments in the platform.ini, read through it and disable the check.
If you don't know how to do it, you shouldn't be doing it
