if you resoldered cobba(sometimes you need to change it) hagar and ccont then...those 5 sec of netw appear because the phone works ok on Rx but not Tx(change the PA 08109) this should work
after you resolder all that sometimes you need to reflash the phone
good luck

Disaster

i agree with TX problem , might is it PA, might it is TXDET, might it is antenna switch , might it is TXC, might it is .....

check it by netmoniter, see on test 01, and when phone is register to network, is it has *5 (GSM ) ore *0 ( DCS) on right side ?
