Thanks for your input. I have done so many SD unlocks on various Mio devices that I don't think that there is any model which I haven't done before :)
All SD unlocks works the same way, just SD card name varies. As you suggested, 90% of all Mio devices see SD card as "Storage Card" but some newer models see it as SDMMC, that's why I prepared 2 options (v3 and v4) for SD unlock, because I'm not sure about this one as I don't have a backup. I will download your files, for the flash disk unlock if necessary. Thanks for providing it.
