After some time my 3210 can not connect to GSM-900 cells.
When i'm in the city it reconnects after some waiting to
GSM-1800 cells, but when i quit the city - no connection.

NetMonitor monitors the presence of BTSes of my operator but i can't
connect to them.

Using TEST 17 i tried to connect to the GSM-900 cells but the phone didn't connect to them and shut down after some time (sometimes not)

This problem isn't corrected by reflashing.

I can connect to the the network with this card on other phones.
Is it a SW or HW problem?

This problem apeared after I changed the lights in my phone and tried to solder my self-made flasher to the PCB of the phone. (I'm not sure, cause i made it 3 months before i noticed it).(After i purchased a generic one).

It was corrected for some time using Rolis Nokia Tool 1.7 but i don't remember what i did. After the first flashing (some time after, when i quit the city) it re-appeared.

The phone isn't locked (before it was unlocked). And i found a piece of (SCOTCH) collated on a part of PCB.

Thx in advance

What does this mean?
And where is it located?

I noticed that sometimes when i press the fone where the antenna is located it shuts down.

I tried making faid and restore IMEI, like described in Eeprom Tools tutorial (i use v 3.1) but the phone still cant connect to GSM-900 cells.

Another thing, Eeprom Tools cant set full factory defaults on my phone.

BTW, shall i first correct FAID and then IMEI or vice versa ?

ANd occasionally when i speak then fone turns off.
When i take off the back cover this happens less times.
And sometimes when i speak, the network strength bar decreases drastically and the fone turns off.
