hey.. that's what happen to my e606 phone.. and i'm still trying the software to fix that up.

I read somewhere else that we could use Nokia multimedia converter to convert it into the correct polyphonic ringtone.

we can't just use the computer .midi files or .mid files.. we must convert it first.

I have tried a program that could convert the sound files into polyphonic midi files.. and tried transfer it into my phones.
and it works... no bad request.. msg box pop up.

my phone does this same thing for certain files ... try to look for the song you want at google maybe???anvil studio can help you shorten midi files

Uhm... you're not the only one having this problem, me too.
And it's not a matter of file size, because in that case the error message is different...

I should try the same files with the e808... if I'll have enough spare time, I will post the results

I've tried a couple but it still doesn't work, well, does anyone have one that they know will work. Can they email the midi to me so I can try it out...

might be the song itself?

Does anyone have this problem? When I try to upload a midi, my PC gives an error message stating "Data Transfer Failed. (BAD REQUEST)". I can upload everything else except for that, anyone got any ideas on this?
