I have rooted my Sony Xperia M2 Dual (D2302) using KingRoot and it currently has Sony stock firmware (android 5.1.1, build: 18.6.A.0.182) with locked bootloader. I have checked the root availability using Rootchecker app from play store. To link the apps to micro SD card Link2SD app has been installed from play store. A 16 GB class 10 micro SD card has been used to provide the second partition. The partitions I have tried (using Minitool) are-
- 8 GB FAT32 + 6.8 GB EXT2
- 8 GB FAT32 + 6.8 GB EXT4
- 8 GB FAT32 + 6.8 GB FAT32
In each and every case when Link2SD is launched, selecting ext2/ext4/fat32 shows "Mount script cannot be created. mount: Operation not permitted" error. I have rebooted the phone several times, checked root permission again and also tried to "su" from terminal and there were no error. In the Link2SD storage info the second partition is shown as "not mounted" partition. Why this error is being occurred? What should be the solution to this problem? Is it possible to solve the problem by running custom mount script?
