I am already running Midnight ROM v5.3 (ext 4) flawlessly for a while however I would like to try flashing the leaked verison of gingerbread to test out. My question is that do I need to ODIN back to the stock OTA of android that came with the phone in order to flash the leaked gingerbread ROM or can I just flash over my Midnight ROM? I am not sure if the leaked version of gingerbread is RFS or Ext4. I already have the purple edition of CWM. If anyone can help me on this that would be great!!
