Root Refreshing install CM7

[prjMayhem]

I'm looking to re-install my CM7 ROM to 'refresh' it after lots of app installing and tinkering.

When CM7 is installed is anything copied to the SD card?

Do I backup then delete SD card contents, reboot phone and reinstall -or- install over the top of the current installation and clean up the SD card afterwards?

Hello prjMayhem!

To my understanding, all you do is:
1. NANDroid Backup from recovery.
2. Titanium Backup your apps,games etc.
3. Full wipe (from recovery). #Wipe All user data#
4. Flash!
^ Always for a different ROM. Leave your SD card as it contains everything, files, root etc.

Some apps store stuff on sd, which you can usually spot by the folder names, but there's no need to do anything to sd when replacing the ROM.

If you just want to reinstall the same ROM you can just flash over. Unless you've modified the ROM itself not a lot will change.
