If you installed lineage os rom 14.1 and when you trying to access external sd card I get error: “can’t access try with advanced root permission” even if root access is enabled and root is accessible.
Method 1: Download ES File Explorer
ES File Explorer File Manager allows you to manage your all kind of files easily on your Android tablet or phone. The default inbuilt gallery of Android isn’t a good solution to access and manage files and you need a third-party powerful file management solution to manage files stored on the SD card of your device and on the internal storage.
ES File Explorer File Manager is a feature-rich solution to manage files on the go. Some cool features of this amazing app are listed below:
Method 2: Through TWRP Recovery.
It has been reported that deleting the ‘.android_secure’ folder on the external sdcard (eg. via twrp) fixes the issue.
So you have to boot into TWRP recovery and then delete this ‘.android_secure’ folder from there then reboot your device.
This will do the trick if this still not works then follow below method.
Within the app I managed to rename android_secure folder and now I can access from the bookmark page as it should normally.
To rename the folder I had to access /mnt/media_rw/77B8-1D11 instead of the not working /storage/77B8-1D11
after renaming android_secure all is working ok.
