Why should I you have internet with you. You can search on anything on how to properly sign an APK I am not here to spoon feed the likes of you. I can share files but not for you kiddo, I only sell files that comes from our own development not from the leech you were saying also I didn't sold any mu origin files that comes from here
You don't know who you talking to kid we started development of mu origin files from version 1.4.3 july 2016 that was 2 years from now and I contributed to it alot here in RageZone.

Anyway this files have a working cross server go find it out how to configure it properly by checking the config from KFCenterServer everyone must use the Correct IP Address need to set up IP address on database
Tips for the files
muserverlist>t_serverdata
mu_kuafu>t_server_info
ZTServerList needs a tool to generate serverlist.dat <- this must have serverid,servername,serverip
