BlackBerry Passport Signal strenght problem


Hi all maniac BlackBerry. I got used and working BlackBerry Passport with broken...i hope...antena GSM. In home network is not connected - only emergency call. In outdoor signal is maybe 3/5 bar, sometimes 4/5 bar.



Phone without simlock. Sim card slot 100% working. In manual mode Phone find operator GSM network.


I inspect motherboard under magnifyglass and i found broken two component.


One is condensator and second is diodę. See image in attachments.

But i dont have correct schematics to find this component properties. I have hotair station and i desoldering two component from BlackBerry 9900 to import to Passport See image attachment.

But still no network in inside home. Maybe this is broken antena coil? I need help from expert to repair this Best in my opiniom Phone
