Help Me Fix An Embarassing Mistake (Without Losing Data) :o
I finally fixed it by flashing the ROM. I tried this before but forgot about all the extra hoops I had to go through to get it to work with my particular phone. Also I probably assumed it wouldn't work because the phone was locked.
The OTG mouse didn't work because my phone doesn't support OTG. I tried it even though it wasn't listed in my phone's specs. None of the other suggestions worked because my phone was locked.
