[Q] Porting Help Please!!

For one of the devices i am developing for there has been a clone released that has Jelly Bean. This device only has ICS but the clone device has all CPU and Resolution the same. So it is portable. My question is how do i port Jelly Bean to to ICS? or make it to where that Jelly Bean ROM will work with that device.


I am not a noob and I know a lot about android so I can get the job done I just have no idea on how to port jelly bean to ics.


Thanks in advanced!
