Hi. My phone battery had died and so i took it out and then put it back in, hoping that it would have the effect of boosting the battery a little. When i turned it back on it asked me for my pin number which was fine because i know that but then it asked me to "enter security code". This has never happened before. I entered the default code of 0000, as per the instruction manual but it doesn’t work even though i have never changed the code. The codes on my phone, written below the battery are: Imei: 359103-00-153579-7 and S/N: 609KPMZ153579. The phone does not accept less than 4 digits or the hash or star keys. I am able to receive phone calls but i can't get past the "enter security code" stage. I'd very much appreciate it if you could help me unlock my phone. Thanks
