There is a difference between the Pi2 v1.1 and the 1.2. After doing some research I came across this that details differences in v1.1 and v1.2 as of OCT 2016 -

It states,
Raspberry Pi2 Model B v1.2
IMPORTANT: PLEASE UPDATE TO LATEST VERSION OF THE OPERATING SYSTEM
Previous versions of Raspberry Pi 2 Model B use the BCM2836 SoC, which contains a quad-core ARM Cortex-A7 processor. The new release Raspberry Pi 2 Model B v1.2 board uses BCM2837, which contains a quad-core ARM Cortex-A53 processor. It is necessary to update to the latest (October 2016) version of the device firmware and Linux kernel to allow the board to boot up properly.
With that said, has anyone been able to boot Kali on a new Raspberry Pi2 with BCM2837? I can confirm I have the BCM2837 by looking at the print on the chip.
