its better to reball UEM then rehot
reball UEM ,tested in many set

when i power on the set it shows signal and than goes down?

Come On Xpertz Really Need Ur Help?

change uem with new one.

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.

pf and/or uem faulty

i reball uem, change meljoiner, change filters, change pa all conponents taken from ok set, still cant found the solution, already write full pm?

very very interesting , no one can reply!

just erase & downgrade to versi 6.01

Then Only Way Is To Change Uem.

mostly problem pf or heger ics check 2 parts not solve only uem......... ;)
