your CDA region has to be the same as FS region. after you do that it will work normal. for example my fs is W800_R1BC002_FS_EMEA2 and when i just flashed the phone media player worked, but the phone mode didn't, it reported the same message you had. then i have put CDA file W800i_CDA102430_2_EMEA_2 (the matchig CDA region to FS) and now my phone is happy and healthy lol
