Acer Veriton Z4620G upgrade CPU

Good day!

I have the All-In-One Acer Veriton Z4620G with G550 CPU installed. I want to upgrade it to i5-2500 (CPU ID 06A7 Rev 2D). When i installed it to motherboard and power on AIO, i received the system error "Unsupprorted CPU Installed. PC will automatically power down in a few second".

I tried add CPU microcode to BIOS file via MMTool, but this was not successful, the error still appears.

Apparently, in the BIOS there is a test for the use of certain processors models.
Can you help me to patch BIOS file? Link to original and modified BIOS in my cloud drive https://yadi.sk/d/EeAvgkBLLlpXjQ

Updt. I found BIOS A1 version, but after flashing it the error still exist. I uploaded A1 version to disk, the link is same.
