Hi,
 
have the same issue on Z2a, which is unfortunately quite different from Z2 and nobody around wanted to service that phone. I needed to change the battery (the original was gone after year and half) so I managed that on my own. The original battery was heavily glued to the logic board (however it's hold on place by the frame and the glue is useless - except to make it hard to replace...seems those devices are build to last the same time as the battery and than you should bybuy a new one...). Anyway I succeeded with the replacereplacement but when re-assembled again the signal is completely lost (SIM still accessible), antenna and connection to the logic board seems to be fine, nothing damaged, there're no coax cables on Z2a for antenna connection. Factory reset did not helped and I'm not in mood to wait (and pay) several weeks for new antenna/logic boardboard as it seems I broke something when removing the original battery .....
