I use oneplus one with CM13. There is a privacy guard that allows to block any permission for any app/service. I applied this feature to Google Play Service. Now it asks me allow some permission and hangs right after device booted so I can't even unlock the screen for letting the service do what it asks. I can boot to recovery mode and do a factory reset but I would like to keep some files/fotos from my android. The device is on the stock recovery and firmware with OTA update. Not rooted. No USB debugging mode is on. Is it possible to bring the system back to the normal state or at least to pull the files from it?
