hi, im sorry if this have been asked N times before.

will be getting this phone soon. How do i flash custom ROM on this thing? im thinking CM10

I came from G.nexus.
On nexus, the steps are : get the 'galaxy nexus toolkit' which can unlock bootloader, flash CWM recovery, root it.
Then i just DL custom ROM images to be put in it and flash using CWM recovery.

Not sure how to do it on this phone tho
