Hi eakrin, I went through your blog at http://my.opera.com/eakrin/blog/ and I got very interesting and useful thing. I went through Eakrin 's Blog (???????????) - by Eakrin (Ake ???? ???) for installing EzxMpkg. I followed all what you have mention there. I'm using Motorkr E6 from just last one day. My problem is after following all i.e. replacing the .system file in my card still it's giving error below Invalid application file! The file cannot be used. After reading all those posts I think you can help me out of installing .pkg files in my E6. Thanks in advance.
