MBP 13” 2020 won’t turn on after 11.3 Beta 3 Update

I left my laptop downloading the update because it was taking sometime. After an hour, I saw my laptop’s screen was black. So I tried powering it up, but nothing happened. My laptop was not drained, because I left it with the power cable attached to it. My MBP is showing no signs of life. I have done all the things apple support was asking me to do. SMC Reset, Recovery mode, discharging everything, but there was really no response from the power button. Has anyone experienced this? And did you manage to fix it? This is so frustrating. I just wanted to update my laptop. 😭

I say, update might have bricked the firmware, happens sometimes. Also, depending on the model of your laptop, it might have fried the CPU (older models' hardware design was really bad, and some Macs tend to shortcircuit themselves randomly).
In any case, take the laptop to the repair shop (or Apple Geniuses, if it's on warranty), nothing else you can do.
