and S60 OS...

For installer, u can search at this forum..

Today I just installed FTD on N95. But I wonder if I can lock only UARFCN with no scrambling code or not. For instance, there are two UARFCN 4382 and 437, in each of which has 2-3 scrambling codes. In this case, I tried to press 0438200000 or 0043700000 but it didn't stay on UARFCN I wanted. Anyone has the tips for locking only UARFCN (with no scrambling code specified as manual says) ? I would like test softer handover on each UARFCN.

-----------------------------
Quoted from FTD manual
"11.6 Display 46.06: FDD BTS Carrier Lock Mode

This screen is used in BTS carrier lock mode to retrieve FDD Frequency and Scrambling code. The frequency and scrambling code is entered as one decimal value. Both frequency and scrambling code are five digits. e.g. entered value on FTD is '1060000040', where '10600' is the BTS test frequency and '00040' is the test scrambling code. To clear the BTS test mode user enters '0000000000'."

I have found that if I locked the phone to particular frequency and scrambling code. After I cleared it, phone seems to stay on that frequency for a while. So I think I can use this trick to make phone stay on the frequency channel I want to do handover. It might need a few attempts sometimes.

However, to check handover, I tried to check on page 46.05, freq and scrambling code are not updated while making call (FTD_SB_RRC_PLMN_FREQ and FTD_SB_RRC_PLMN_SCR_CODE). They freezes at the initial values. So instead I checked page 41.12 for frequency of home cell (FTD_SB_WDSP_FREQ_INTRA) and 41.13 for active scrambling code with highest Ec/N0 (FTD_SB_WDSP_DETECT_INTRA_BSID_1) -> Is this the primary scrambling code ?

If yes, then in the last 3 screenshots (please see the picture below), it means handover was successful from scrambling code 372 -> 140 -> 372 of frequency 437. Am I correct ? I just wanna clarify how I can observe WCDMA handover on Field Test for S60. Thank you in adv.
