ARE THERE CONVENIENT METHODS TO DOWNGRADE THE BIOS OF ACER AN5-515-55-50VC

ARKlyntxHarry85

UNIT: (AN5-515-55-50VC) I installed a higher version of the BIOS in the (https://www.acer.com/ac/en/PH/content/support) for my unit and after a while, I wanted to rollback to my older version/original bios version but I don't know how to perform the method properly if there are some methods. Please do assist me for this.

For advance user.
there's a way downgrading bios by uninstall it then modified one line in the bios-installer file so we can install the old version like i was did here https://community.acer.com/en/discussion/644077/nitro-5-an515-45-bios-version-1-12-has-poor-cpu-perfomance-you-might-need-to-downgrade-smh plus there are some addition where we need to hide windows auto update bios.

even tought i already done this by couple times, i (and all the saviour here) will not recommend it to you as it was quite harmful and i'm not sure if it works on all models especially the newest. in the end it all depends on you, dwyor.

Hi @ARKlyntxHarry85,

If you reset the system the default BIOS version will be reloaded.
