It's Not A Uem Problem, On S/w Side Firstly Flash With A Good Pm & Then Check Your Tx Line Clearly Bcos This Fault Is Related To Only Tx Section Jumpering Ant Sw In 6610 & 3100 Is Not An Intelligent Task Bcos In Tx Line Both Handsets Have A Filter Inductor Coil So Making It Jumpered Will Cause The Signal To Be Grounded So Beware About That

Dont Make Direct Jumper Put Ok Antena Switch. Second Step Is Use Working Mjoiner. Third Step Is Uem.
