Can you explain what you mean by "doesn't find it"?
- the pink hearts (standby) don't change to red (communication in progress) when you attempt to send the file?
- the pink hearts change to red but then change to blue (error)
Step-by-step instructions for the Sony Ericsson are here: http://tama-zone.com/index.php?showtopi ... &p=3394616
You can't send the .zip file. Extract it. You'll find some .jpg files. These are the download files you can send (one at a time.) Even though they're ".jpg", they're not normal jpg files. There is some extra data in them. If you edit them on your computer, your paint/photo program will most likely corrupt/delete the extra data, making them unusable as download files.
If possible, check the file size on you phone, and compare it to the file size on your computer. If they aren't the same, then the file was corrupted during the Bluetooth transfer.
Also verify that the file is for the type of Tamagotchi you have. Most Tamagotchi iD files don't work on the Tamagotchi iD L.
