I have done so on 4 Ericsson phones: T20, T28e, T29s, R320, but to my surprise, they
all still show the same "NO ACCESS or NO NETWORK" !!!

The PA I used was brought in from Dubai and they were Tagged T28 PA
Numbers on PA:
RM009-10P
E38666_1
0024
MEXICO
I am sure of my job, I solder them very neatly with Rework Station, this is since the
phones come on.
So now what seems to be the problem?

This is a challenge to us all !!!
Am I using a fake PA, or is it that PA is not the fault?

Every Ericsson Expert, lets face it.

Starting with you.

Sir, u just missed sumthing u must change also ur RF pre amps becoz when u change P.A. it will result into low sensitivity in ur RX dats why the phone can't see networks...Hope this helps u
