lenovo A6000 not booting I have a Lenovo a6000 which I recently flashed and when it rebooted I cant even see the logo and if I press the power button it just vibrates again and again in a few intervals,I tried to boot into recovery by pressing volume up and power button but that was also no use what can I do to get into recovery
To get into Recovery you need to keep both VOLUME + and - keys pressed down and hold .. Also press the POWER button till you see the Lenovo logo. Then let go of the POWER button but keep the VOLUME Buttons (both + and -) pressed down until you get to RECOVERY mode.

Hope you have backed up the Stock ROM before you did the Port ROM install.

Another way to get to Recovery is to flash a new Copy of RECOVERY (CWM).

If your phone is not booting then, keep the Volume Down button pressed down with the POWER Button, then release the Power button on seeing the Lenovo Logo, also release the Volume button.

This screen looks almost the same as the Lenovo Boot Screen however if you look closer, to the bottom you will see
