Great thanks. How long does it typically take, should I allow 3-4 hours?
Are you gona root and install it the proper way or use the CM installer?
P.s, are you on 4.1 or 4..3 mate?

Flashing typically should not take more than 15-20 minutes including the initial reboot. Make sure you flash a custom recovery first (Philz, CWM or TWRP, latest versions if you are planning to flash JB 4.3+) and then "blitz" your phone by wiping cache, dalvik, data, system and, especially coming from older firmware (i.e. 4.0.4 to 4.1.2) you need to wipe/format the internal SD to avoid any issues.
This will of course delete any personal data so you should back that up to either an external SD in your phone or if you haven't got one to your PC and then restore it from there.
If you flash JB 4.3 and up you'll have a new partition structure, where you restore your files to sdcard/0 - for this you need a file manager like ES or any that more often than not comes with your custom ROM.

Wooky, which version of the S3 do you have?
I'd like to get this thread moved to the right forum before we're talking about multiple ROMs.![]()
I still haven't got around to doing this yetmight get chance next week
How are others getting on with Cyanogenmod?
Any improvement in battery life over stock ROM?
