All-f2fs boots okSim not detected so no phone or data, as in OPBrowser FCsEdit; it says sdcard is corrupted and a notification comes up "touch to fix", I will backup the contents of the fat32 and see if it does.Edit2; not tried "fixing" it yet, looks as though it formats something, but looking at file manager, it seems that it has created its own storage, /storage/emulated/0, with new folders (eg music,DCIM,..), as with a freshly formatted sdcard, but I still have stuff on my sdcard FAT32(music, DCIM...) I need to backup.It is late here, will try in the morning.Works smooth as kitkat, nice.......
