Well, I'm still new and uncertain about a lot of this stuff myself, but I can tell you when the apps aren't working and such, it means you need to wipe the device before flashing.

I still don't understand the ext 2 to 3, 3 to 4 stuff myself, but I do just follow the rom cookers directions. For example, Fresh 2.1 requires partitioning of the SD for the apps2sd to work, then you need to upgrade 2 to 3 but leave it at that, nothing with 3 to 4.
