Hi All Has anybody succeeded in opening the NW A3000 without damaging it? It seems that first I need to remove the circle part with sony logo at at the back but I don't think it can be done without ruining this part. I've tried but no success just scratched it. Can the front cover be removed without breaking it? From where can I buy parts for my sony just incase I ruin it. Sooner or later I'm going to need to open it to replace the battery so if someone succeeded kindly help with your advice. Thanks
