I recently bought a backup battery, so I could have two. Ever since I inserted it into my phone to charge it up, the phone has not operated.
I have since ditched the “new” battery and gone back to my old one that was working fine. But still the phone won't turn on.
When I push the power button, the “Samsung” logo flashes for about 5 seconds and then it shuts down. Then I can't even get it to do that again, unless I remove and re-insert the battery.
the LED has been doing some funny things. if I let it sit after a failed attempt to start up, it sometimes flashes purple and red for a few seconds and then it turns blue. when it's blue, the power button still does nothing. I still ahve to remove the battery to get it to even “try” to turn on. I can find nothing in the user guide about blue or purple LED status.
I've tried the hard reset (holding down the H key while I turn it on) with the same results.
Is my phone dead? Is there anything else I can try?
