With some new firmware, some
users have reported that the
'send command' (thru bluetooth,
IR, ...) fails; it is due to a
'copyright protection' introduced
in the new OS. This happens only with some kind of files
(eg: .sis, .jar), in such case,
simply rename the file (eg:
with .SIS_ ) before trying to
send them.
You can use fexplorer/x-plore (see Downloads section) to find and rename the files.
Other way is to use BlueFtp or SendJar (see Downloads Section)
