if software will not solve. then its time to
consider as hardware problem.

try first the antenna as suggested above.
desolder or replace RF parts.

For detailed reference you must have service manual.
try to get one from landys page

to gazt:

landys user: mobile
pass: elibom


to sergioems:

Soldering station will cost u about $200-300
Forget the oscilloscope 100Mhz it will cost u
about $1000.
Aside from osc, you need 1800 Mhz rf gen.

as a start, buy only hot air-soldering station

To resolve harware problems you should have fistly:
01- hot air solder/desolder
02- Multimeter
03- You should have the manual service of the phone

When you have all this, contact me to give you the method and the description of repairation.

TO SMARTYMARTY

HI, low signal or loss signal ,the problem it is the same,
in 80% of phone you must resolder cobba ic ,in the rest of phone
may be have rf pa module broken or duplexer. the pa module is built into ceramic support and if the phone fall down....
remeber that in the nokia phone if tx is ko it not rx because the phone must send the data( imsi etc)after it show the net .
in the other model of phone ( ericsson samsung ) rx and tx are
separate

ciao mirko
