I have HTC DROID DNA with the firmware of HTC ONE M8 and it only allows to use MTP file transfer protocol. I can copy some files, but on the majority of them Im getting "Error getting file: -6: Not Supported" error. Now Im transferring files via FTP server, but it is very slow and I would like to fix this problem.
I have Ubuntu 14.04 LTS installed. Are there any solutions? Thanks.
