Hi guys , My friend has got a second hand 6630 two months back, it has a wierd problem i've ever saw, he cannot make call from contacts or Logs. . . Tried updating firmware and also reseting using *#7370# code, nothing worked, it will work for first 5 minutes or so after the phone is restarted, then again same problem, will flashing work out? I took to my local mobile vendor, he told he doesn't 've firmware for 6630, he just clicked 'FACTORY SETTINGS' connecting to that Tornado flasher.. But didn't work out that too.. Any other remedy frenz?
