Hey there,
may I hijack your topic here? 
I bought the same SD Card and sadly, even after working through this topic here, I still can’t get the Toniebox to accept the SD card… It lights green for a brief second, then LED stays off and no sound is played. I should mention though that I seem to have a “newer” v1 / CC3200 which Tonie seems to sell right now: v1.2.1.
What I tried before:
- Used “Rufus” as described in the video linked here to just format the card with FAT32: Trouble finding compatible SD card - #4 by housejet. Didn’t work.
- Used Win32DiskImager as you described to create an image from the original disk, then write it to the new SD card.
- As my Windows Disk Management didn’t let me resize the partition, I just left it at 8GB and left the rest unallocated: Doesn’t work.
- I used “IM Magic Partiion Resizer” to resize it and use all the unallocated space behind: Doesn’t work…
Do you maybe have any other hints or ideas what I could look for why it keeps not accepting that SD card?
Thanks and greetings,
Andy!
