Problem with a 7230
 

Hello everyone, I am new here, and it is refreshing to see so many people that may be able to help me. I had a 6230 for quite a while, but a friend of mine had a 7230 laying around that he quit using about 6 months ago. I put my sim card in it and let the battery charge for quite a while, but it will not turn on. The red light at the top flashes once, then flashes three times, and after about 2 seconds, it repeats this, and has done it nonstop. I tried a battery out of a different 7230 that I know was fully charged, and yet nothing. My friend said it worked fine when he stopped using it. Any ideas?
