I congratulate and thank all the guys in the forum who helped me to understand the BB storm 9530.I am in india and had a unlocked BB Storm.I did upgrade the OS to 5.0.328 with the guidelines in the forum. A small correction i did was when I started my upgrade process using loader.exe the process was going to a loop in intializing the device and was halting with the horrible error 507 white screen . After 2 days of googling I found that battery is to be inserted after loading is over and when display shows waiting for device initialization insert the battery and my BB was up and ready
The CDMA settings for BSNL was next step:
Again the forum guys helped me.The discussion was on GPS settings.I downloaded the QPST as suggested in the forum.configured the RIM Virtual ports in QPST.After that QPST detected my phone with correct ESN number.
(note:##000000 gives the cdma setting screen where u will get ESN Number.)
Now open the QPST check the correct ESN Number. Obtain the mobile directory number MCC, MNC, CDMA channel number, SID and NID from your carrier.(eg for BSNL MCC is 404, MNC 00, SID and NID depends on state where MSC is located).In QPST select service settings and fill the NAM programming parameters like MDN,IMSI, Primary channel number,secondary channel number,and in system parameters set SID,NID and PRL can be obtained by the carrier.Before modifying check the parameters by reading the Phone settings and save it to a file.Once modified select write to phone.U will get an error message nvram write protected. Still the parameters will be written and phone reboots.The phone is ready for use in your country.Of course if u want to use for data your carrier should have an agreement with RIM to enable BB email account.If 1x EV is supported the phone can be used for DATA by adding this phone as a dialup modem with #777 (in India) I have no information in other countries.I feel it is same across globe.
