You must install all the three debs Javispedro provided. Use the terminal to do so with dpkg. If you have no clue what dpkg is this is what to do: Put all the 3files in the MyDocs folder (it's the first one you get when putting the device in mass memory mode). Open terminal Type "devel-su", press enter than type "rootme". Type "dpkg -i /home/user/MyDocs/fmrx*" and press enter.
