My phone reboots whenever I try to manage apps or check my storage settings or open the Play Store. I checked out last_kmesg and found that there was a kernel panic caused by an issue with the user data area. I can't clear user data through settings so I used Titanium Backup to start clearing user data and it died on it's ass when it got to Google Play Store.
I tried selecting just the Play Store and clearing data and it crashed straight away so I'm pretty sure it's the Google Play Store causing the issues. Given that I can't clear the data while the OS is loaded is there any way of doing it from TWRP or suchlike? I want to clear ONLY the Play Store info, I don't want to have to do a factory reset and clean ROM installation as I haven't got access to a USB cable to transfer ROM files over this weekend and it's a royal pain having to set everything up again.
I'm on Cyanogenmod 10.1.3-RC1, android build 4.2.2.
