I recently flashed CM10 on my galaxy s3 and im trying to do several things.. First, flash a different rom. Every time i try to download one it just simply reads "Download Unsuccessful". The roms that I tried were Liquid Smooth as well as Jelly Bam. Also, when I try downloading the files on my mac and copying them onto my phones sd card (Using Wifi transfer because my SD card won't mount, which is another problem), they don't show up in my recovery and therefore I can't flash them. Second, how do I clean up the 0 files made from flashing CM10? I really enjoy CM10 Nightly, but it completely screwed everything up and has sent me into deep frustration.
