hi

first,check ext.antenna, antenna switch,then pa finally two bga chips.
if your problem remains after changing ant.switch and pa,you should reball the both of BGA chips(dsp)which are below CPU.one by one..hope you succes..__jero__

No ACCESS mean you have RX but no TX - so you need to check TX line - Antenna, antenna connector, PA and power IC. But it's probably PA problem.
