Question about Sony Ericsson K800i Cellular Phone

Cannot use this file

I have a Sony ericsson K800i. Last week the ringtone changed to the Sonny ericcson default. When I try and change it back to one of my MP3 ringtones or one of the ones that came with the phone, it says "cannot use this file" Tried doing reset , taken batt out etc to no avail.

    I have the same problem, my ringtone changed to default on its own and now I cannot set one.



    Note: I formatted then removed the memory card, then did a normal master reset then a FULL master reset as suggested above. However, now I have the exact same problem only I have now lost all of my data as well.



    The only thing that worked for me, in case this is a clue, is I can set a ringtone for a specific user. So when my sister calls it can play an MP3 but if I want it to play an MP3 for anyone else eg/number withheld or anyone else basically, then it says "cannot use this file".



    It also seems to have lost all the built in MIDI ringtones because they're listed eg/"motivation" but it can't play those either.



    Please help, this totally bites. Thanks.

Sony Ericsson :: K800i - Apps Or Games - Operation Failed


Check the file format of the application if it's compatible or not.

try to download here : http://phone.mobile9.com/i/sony+ericsson+k800/

If you still got error on installing the applications,try to reset the phone. Go to settings > Master reset and choose if you want to reset only the settings or the entire phone,if ask for a code,the default will be 0000,but if you change the code before,enter your desire code and after that the phone will restart and it will go back to its original settings.


Good luck...
