Quectel-CM hanging after ifconfig wwan0 0.0.0.0

Somehow the modem got into a bad state where the quectel-CM always hangs at a certain point. I have another device working that I’ve compared AT command values and they all line up, but one works and the other doesn’t. Is there a way to reset all quectel-CM and QMI processes/files easily

My personal solution ended up being a newer version of quectel-CM that didn’t have the issue with hanging, just fyi
