Pinebook pro nearly unusable after using manjaro-arm-installer

[TheCounselor]

Good afternoon everyone, about a month ago I tried using the manjaro-arm-installer script to flash the emmc. This completely bricked my device, no booting from emmc or sd card, not even the green LED power light would come on. Finally got around to opening the thing up and hitting the RESET button. This got booting from the sd card working again, but the performance is absolute garbage. I can get to the manjaro KDE desktop but it will freeze if I try to do anything useful. I'm at my wit's end with this thing, any guidance you can offer would be greatly appreciated, Thank You!
