+## Granting full permission for apps data (HACK)
+
+
+This is a temporary hack to combat against the apps permission issue on Android 11. Whenever an app is open it will always enable a property (persist.sys.nodataperm) to make it execute a script to grant the data full permissions (777). The **correct** way is to use `sdcardfs` or `esdfs`, both need to recompile the kernel or WayDroid image.

+Arknights, PUNISHING: GRAY RAVEN and other games won't freeze on the black screen.

+```
+sudo python3 main.py install nodataperm
+```
+**WARNING**: Only tested on `lineage-18.1-20230121-VANILLA-waydroid_x86_64`. This script will replace `/system/framework/service.jar`, which may prevent WayDroid from booting.
+
+
+Or you can run the following commands directly in `sudo waydroid shell`. In this way, every time a new game is installed, you need to run it again, but it's much less risky.
+
+```
+chmod 777 -R /sdcard/Android
+chmod 777 -R /data/media/0/Android 
+chmod 777 -R /sdcard/Android/data
+chmod 777 -R /data/media/0/Android/obb 
+chmod 777 -R /mnt/*/*/*/*/Android/data
+chmod 777 -R /mnt/*/*/*/*/Android/obb
+```
