I have a z6m from sk telecom korea. Everything's fine but the only thing makes me crazy is the fone can't play mp3 files . I've tried to flash the fone with alltel, verizon, cricket monterspacks with hopping the fone can play mp3s after flashing it but i couldn't get it done. When i flashed it with rsd lite 4.3, i got the message "Fail flashing process. Phone (0000). Error checking the ram downloader (0x709F). I got the same problem with any z6m MPs .
Anyone knows how to solve this problem, please show me what i have to do to get my fone play mp3 files.
