I'm interested in putting CyanogenMod on my Samsung Vibrant (Galaxy S). The FAQ on Cyanogenmod says:
Q: Do I have to wipe my data before I install CyanogenMod?
A: Short answer: Maybe. Long answer: Maybe.
I understand there's a possibility if something goes wrong that I might have to wipe my phone. However, in the Vibrant instructions right after booting into ClockworkMod Recovery it says to "wipe data/factory reset" and "wipe cache partition". That seems to me to indicate that a factory reset is required, which I would think would wipe out everything on my phone.
Is it just that the Vibrant's instruction require a reset or am I not understanding something? Thanks!
In my experience, yes. I tried without wiping and CM7 failed to boot.
