3310 5 second good after it no network
 

3310 when i turn on for 5 second is OK but after it no network and in speaker i have strange noise. How to repair it. I rehot cobba hagar. and nothing. PLEASE HELP ME.

Try to update FAID,if that dont work then you must replace your P.A. If you need more help just ask.

whats look like p.a ? what is the number of P.a

If you have network 5 sec -> try rehot CCONT(power control ic)
If you have bad noice in head phone when phone search network(Bad Power Amplifier PF08109BN,and you need change it ,or hagar short to GND)
I you have bad noice when you call (Try reball cobba or change it)
Good Luck!

Zender,

Can you try to check, is phone have TX power ?
you can get some light up LED when you have make phone call or some one call you.

then you try to run wintesla, and set on turn menu -> TX power ->
set level 5 , then see that LED light up or not ?

if you do not have wintesla.,,, please try make 112 call..
