Question Acer Aspire A515-51G Corrupted BIOS - Urgent

May 31, 2021
Hello everyone, I need help fixing my corrupted bios.

My laptop was having serious thermal shutdown problems where it would shutdown around 60º everytime, I figured it should be a software problem, as the laptop has barely 3 years of life and during those years it was cleaned thoroughly and the thermal paste swapped, but even with a clean install of windows and the manufactor's drivers the problem didn't seem to go away. I decided to downgrade my bios to an early version hoping that would fix the issue, unfortunatly, downgrading the bios completly bricked my laptop. I ask for anyone that has any knowledge on corrupted bios to help me. Unfortunatly, the repair shops here (rural Portugal) are not "qualified" enough for such a repair and all tell me to replace the motherboard, which would cost around 200 euros. I know my way around computers enough to know this is fixable (but clearly not enough to avoid this issue), and I can try to fix it with some help. For some context, the bios was flashed, the laptop automaticaly restarted, it installed the new bios to 100%, restarted again and nothing else happened after that. The computer right now turns on, the fan ramps up but nothing else happens, just black screen.

I already tried: reseating ram, removing cmos battery, laptop battery and power and leaving it out for some time, and putting the bios files in a usb stick while pressing FN+ESC.

I am willing to paypal 25 euros (30 USD) or more if really needed to anyone who helps me fix it.

I will be posting this topic on multiple tech websites for the best chances at fixing the issue. This is my main "computer" and I need it to end my high-school programming course's final project.

Here are the specifications of the device and the bios files:
