Hi,

Thanks for your assistance.

So far from my analysis, this is what I have got:

After the BTS sends Location Update Acc=3D ept message to the MS, =3DC2=3DA0the MS responds with a MM status message say= in=3D g=3DC2=3DA0
"Invalid Mandatory Information".

<=3D /div>
In a working case, the MS should respond with a TMSI Reallo=3D cation Complete message which is not happening.

From here, I don't know how to proceed further.
<=3D div style>
Thanks and Regards,
RM

Hello,

In this case it can be some hardware issue with your phone.
If your phone was pre 4.24 software version and it was upgraded it is possi=3D ble to have a corrupted EEPROM and you need to use some software tools to r=3D epair it.

If that is not the case you can try to identify what hardware component is =3D broken by manually pickup a 900 or 1800 operator and check it if it works. =3D If one is working and one not this means your duplexer has issues and needs=3D to be replaced. Other components that might have issues are the PA and COB=3D BA ICs. Considering that a 3310 you can get for free now it's not worth=3D it to repair it.
