Zte z830 No signal

[yurais]

Got this phone from another shop, they unlocked the phone via ZTE Worldwide COdes service, and after unlock no signal.

the removed the external antenna connector and made a jumper, but no signal.

I took the phone and saw there was no continuity between antenna and externalconnector jumper, so I fixed the way with another jumper.

now all the way goes til phone inside straight to a 6 pads connector and there I got lost, I need ideas from experienced people to see If I can fix it.

if you read all of above then you will understand the attached picture

Please let me know if you need a bigger image
