if vboost 5V supply isn't switched off during shutdown (and odds are it will continue for at least 32s after killing h-e-n GUI, possibly longer due to buffer capacitors), then twl4030 power management unit will wake up device as soon as it's completely powered down, as this is detected as attached charger/host and this - as we all know - starts up the device. If you either properly closed h-e-n GUI some time prior to shutdown, or never even started it (I.E. try to shut down a second time), then there's no reason for device to not power off. And next someone using "plz" or "u" or "hlp" or similar '7331' wording can be sure to get on my permanent ignore list. Why do you think would I bother to take the time to answer if you can't even take the time to properly spell out words? /j
