drop down signal

my phone got signal when i switch on and it can reach upto full bars after 5 seconds signal will loose or no network, can any one help me

unit is 3310

Try to change the Cobba and CCONT ic, PA and Antenna Switch.
Might be a help on that.

for the 1st just upgrade ur mobile with full flash, if not good, just fix pa and antenna switch.:o

Hi, B4 doing anything in the hardware make sure the software is ok. Try this:
1. Try flashing the MCU+PPM+EEPROM
2. use Knok phoenix to change back the IMEI and quick set faid
3. Use nk profile to set deafault. When you click the set default all the button should blink and thats it. If Still the same problem Try changing the:
1. 26 mhz crystal osc (if it still d same problem)
2. cobba and pa.
Hope it works....

thanks i will try it the hardware part
