Seems like the eMMC chip got corrupted during the wiping process due to power loss - Always perform dangerous operation while phone battery is unless 50% or above.

If the chip is not damaged, you still can flash your phone with a stock firmware.

You can find flash files (firmware) and the flashtool here. Download it and extract its contents.

This tutorial teaches you how to use the flashtool.
