Restricted Google Play Service hangs up the booting process 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?

Thanks.
This is a known issue when blocking Google Play Services using Privacy Guard on CM13. However there is a workaround if the device has a custom recovery like TWRP installed.


Boot into recovery
Open File Manager
Navigate to /data/system
Delete the file named appops.xml
Reboot.


Since you've not rooted/installed custom firmware, the only option is a factory reset from recovery. You'll lose all apps, but data stored on the device storage will be safe.
