Hi all. I have a flytouch 3 superpad III disco10 Tim6a 5v charger model. The original 8 gb no brand internal sdcard starts saying that /mnt/sdcard folder was only read mode, if I recharges firmware with power-bach button trick, the problem solves, but returns after a few minites, the same if I reflash. So I changed internal microsd for a new Samsung Class10 16gb, reflashed Tim6a, and works flawlessly for many weeks, then suddenly problems became as usual as was. I solved partially with a remount of /mnt/sdcard folder in terminal mode:
mount -o remount rw /mnt/sdcard
But the problem returns after a few second or minutes. Th other solution I have done is based in this post, but with a different point of vold (and slash position!!!):
/system/bin/fsck_msdos -y /dev/block/vold/179:6
This last solution is more time fail safe, at least 10 minutes free of sdcard ro error, and lasting....
Thanks all of you. Good work.
