As you know with the newest update they removed the support for ntfs/exfat external HDD's, because of whom apps like vlc, kodi or Archos wouldn't read any files from it.
I wrote to Philips support about this situation, they informed me that the situation is known, and update will be available soon through internet.
They also gave me a link to download this fix, So if you can't wait, just contact them!
Why don't you share the link ?
