Hey, as we know now for sure the Zenfone 8 has a problem which i think is cause you got some nice brick update i would like trying to help. First of all its really important that check if:
Did it make any sound when connecting it to a computer ?
Get the device recognized in Windows device manager, and if so pls make a screenshot what you got if you connect it.
If you could give me this information i could help. I think its just some weird software bug and not a motherboard issue. Also it could be it if they send some **bleep**ty update that fried something but i don't think that happened.
I for myself downgraded straight to 12 after hearing that.
12 Runs good it has good battery backup and i have a straight line when in deep sleep.
Can give you that if you want it, for now i wont post any links to see if anyone is even interested.
