Developers Tip: If you want to flash firmware without wiping your data, make sure there is no pit file selected under the PIT tab in Odin, then extract and remove cache.img.ext4 then repack as a .tar file. Applies to both combo and 4 file firmware packages. In 4 file packages, cache.img.ext4is in the CSC file. However, in some cases this may put your device in a bootloop.
