If you haven't discovered yet the battery on the rhyme will not come out. There is no way to remove it. puzzled by this hardware construction i only wonder if batteries being removed is a bad thing and this is HTC's way of showing us. So, to do a soft reset:..........
hold down the power button for at least 10 seconds. Phone will power off.
Then turn it back on.
