Think my wemos d1 mini is bricked! Help!

Hello!
I bought a Wemos D1 Mini from a real brick and mortar retailer several months ago, however, between now and then, it has been through the mill of projects, including one where reflashing the firmware (probably buggy) has bricked my microcontroller. Whenever I plug it in (tested cable, code, and computer), the light either flickers in and out like it's a power issue or blue-screens my computer with a CH341.sys error.
Help me get back to the original firmware!
Thanks.

it is damaged. no software will fix it
