so lets say i just root and busybox
then get mobile odin and flash hydracore
can the above work?
lets say in the future JB is released and the kernel is pretty stable can i go back to all stock with JB by flashing the stock rom with hemidall or odin ??
one other thing where can i get a stock rom for my phone
Android version 4.0.3
kernel version 18.104.22.168-N7000UBLPC-CL558418
Yes for both questions.
Check dr.ketan's sticky thread for stock firmwares in note original dev section for your stock firmware or download from samfirmware.com if not available in that thread.
If you cant find stock ics then download GB for your region, you can flash it using odin/heimdall and update to latest availabe using kies
