background - symlinking gone wrong from internalsd to externalsd on android 7, that makes the CrypticFolderName inaccessible to the app that needs it.
i'm at terminal via ADB i get:
cd CrypticFolderName /system/bin/sh: cd: /sdcard/tencent/micromsg/CrypticFolderName: Permission denied
chmod -R 777 CrypticFolderName chmod -R 777 CrypticFolderName chmod: No CrypticFolderName: Permission denied :/storage/emulated/0/tencent/MicroMsg #
but if i do
ls -la on the folder above in the tree, the CrypticFolderName is listed with the same permissions as the rest of the folders, that are accessible.
drwxrwx--x 26 root sdcard_rw 4096 2017-12-12 12:16 CrypticFolderName
what to try next? or - do i need to format the partition that the sdcard is on? which partition is it on? does TWRP wipe do a format?
