hellooo... finally my e398 is back to normal again after
just delete MyToneDB.db and TempToneDB.db from folder a/mobile/audio.. then restart ur phone.. then u can sett ur ringstyle again
and
very easy, its a newbie mistake,
you should put first all ring style to silent.
then deleted the files and then
delete mytone.db and temptone.
just put all rings to silent with pk2 or the same program u used, if have that option, then delete mytone and temptone inside audio folder.
you cant access rings because you deleted ringtones that was being used by phone.
much much thanks..two thumbs up bro....
