Hello dear friends,
Running the latest 10.3.1.2267 I have come up to a rather peculiar situation. Using Viber I cannot use anymore the push to talk feature and also I cannot receive voice messages as this low memory error come up.
Of course there is plenty of memory available and the push to talk voice message feature worked fine untill a couple of days before. It was just before i unistalled and reinstalled Viber.
So I noticed that the folder that voice messages are stored (mnt/sdcard/viber/media/.ptt) has become read-only (R-X) in contrast to the rest of viber subfolders that have all attributes (RWX).
I tried rebooting, uninstalling Viber but the .ptt folder does not delete even with ghost commander. The same goes when viewing it from my PC, I can still not delete it.

So the tricky question is, how on earth do we delete (or change attributes) to a folder or files WITHOUT using multiwipe or erase device feature?

Thanks in advance
