Just a short summary for those not reading the whole thread and who got “bricked” phone after the update.
The phone is most probably not bricked!!! From forum user reports, it seems it is only the display driver that fails. And it seems it only fails on phones that have ever tried installing another OS (even if they reverted back to FPOS and locked bootloader).
If you don’t mind factory-resetting your phone, you can try to unlock the bootloader using a USB-C dock and reinstalling the system. That would be destructive for your data. It is still unclear whether there is a non-destructive way (probably, waiting it out for the next update could help).
In any case, to prepare for the destructive way, you can utilize a USB-C dock to backup your data that aren’t stored in clouds.
