K1 Plus T2/S2 is one of the most popular Android TV boxes with digital tuners, including both DVB-T2/T/C and DVB-S2/S tuners, and I get frequent comments and questions on K1 Plus T2 S2 review. One of the often asked request is a channel editor to use on a computer, in order to change the names, the order of channels, and set favorites.
You can export the DVB data from the DTV app in Android with all data stored in dtv_user_data directory, and in theory, one web based editor is supposed to let you do just that, but it did not work for me.
Everything is in Russian, but it’s still easy to figure out with Load, Save, Channel Up and Down buttons. Most fields seem read-only, but you can change the channel name (recName field), and arrange favorites in the columns on the right. Clicking on Save will update two files in the dtv_user_data directory dtv_preferences.xml and dvb_s_mw_s1.
Once you are done, you can zip the directory, and restore the channel data through the DTV app in K1 Plus box.
