Right, firstly, don't post multiple threads on the same thing!

Second, your battery is too flat to charge, nothing wrong with the phone.

Third, a solid orange light means NOT charging, a flashing orange light means charging, a solid green light means full.

Try plugging your phone into a PC via the USB cable and leaving it for an hour or 2. Failing that, maybe go to the place you bought it and ask them to give you a new battery to try. After that look at swapping the whole unit or getting a refund.
