Finally overcame my social anxiety enough to take my phone to the repair kiosk again. Talked to the pajeet there, said he'd need 30 minutes, couldn't guarantee that cleaning the phone's usb port would fix it. Went shopping in woolies for 5 minutes, came back out and phone was fixed, usb was working agin. Have adb shell working now. WINNING. Having pidser rolls for morning tea. Delicious. MORE WINNING. I could almost be nuro at this rate.
