These are the directions from the cm7 site.
FIRST TIME FLASHING CM7 TO YOUR SAMSUNG GALAXY S SERIES PHONE:
Phone fully charged?
Enough free space (~200 MB) on internal sdcard?
Actually running a Froyo Bootloader and ClockworkMod-Recovery?
- Full Froyo with Bootloaders and CWM for Odin: Captivate | GalaxyS | GalaxyS_B | Vibrant - (Flash as PDA with PIT 512 and Re-Partition checked, do a factory reset if it's not booting)
If yes, we're good to go.
The easy way: (needs rooted Froyo and ClockworkMod-Recovery)
1. Get ROM-Manager from Market.
2. Choose "Download ROM" -> "Teamhacksung" -> "CyanogenMod 7" and install it.
3. Wait until your Phone has booted fully up. There's a lot to do, be patient. Welcome to CyanogenMod 7.
4. OPTIONAL: Install GAPPS (Google Apps) from within ROM-Manager.
so, just to confirm. since I am running firefly 3.0 I can use this method right? Which is basically the same method as as the 2.2 roms.
Just want to make sure before i do something stupid. lol
