Difference Between ZGU and ZGU2 BIOS for Acer Nitro AN16-41 (InsydeH2O BIOS Recovery Issue)

I have an Acer Nitro AN16-41 R1PR laptop with a Ryzen 7 7840HS processor, and I am currently trying to recover the BIOS using a USB flash drive. My laptop has an InsydeH2O BIOS and has entered BIOS recovery mode (Fn + ESC method) successfully. The USB light blinks, indicating the system is trying to read the BIOS file. However, I am unsure which BIOS file to use.

Inside the platform.ini file, I found the following BIOS options:

FD#01=ID,ZGU,ZGUr.fd

FD#02=ID,ZGU2,ZGU2r.fd

This suggests that there are two different BIOS versions: ZGU and ZGU2. However, I am not sure which one my system requires.

My Questions:

1. What is the difference between ZGU and ZGU2 BIOS?

2. How can I determine which BIOS version my laptop is using?

3. Can I place both BIOS files (ZGUr.fd and ZGU2r.fd) on the same USB and let the system choose the correct one automatically?

I appreciate any guidance from the community! If anyone has experience with BIOS recovery on this model, your help would be greatly appreciated.

    CI decided to get a BIOS update for my device. I started the update by following the rules exactly, but somehow the BIOS crashed. How do I recover the BIOS? I can enter BIOS recovery by pressing FN + ESC but I don't know how to do it.
