Desire sv does not start after clear cache I cleared cache memory of my HTC Desire SV then tried to restart the phone. It does not start. I have also tried hard boot on this phone but result is same.

How can I get my phone to boot again?
My phone is working now.I have followed steps to bring my phone up :


Removed battery from phone for 30-40 minutes.
Insert battery to slot and press power-on button, that's it.


"Now, I don't bother about root cause "
