What do you need to know before flashing the BIOS? First you need to download the latest version. Moreover, the software must be downloaded from the official website of the manufacturer of your device. I strongly recommend not to use beta versions, but to use only the latest working verified version. Take your laptop seriously to the mains. Ideally, if you do this through an uninterruptible power system. Make sure that the flash drive that you will use is verified and reliable. If during its use you noticed any problems (errors, data loss, etc.), you need to find a worthy replacement for it.
It is strictly forbidden to turn off the power of the Asus device. Updating the BIOS will not only fail, but the motherboard will also fail. Also, you cannot press any keys during this process.
