- Not showing any files suddenly (No books found)
- Constantly showing "updating" forever
- Bootlooping (to taste)
Here's how I fixed it:
- Fiddle around with hard resets or whatever (This will not help, but you can try it if you want).
- Crack open the kobo.
- Take the SD card off the back and put it into a reader.
- Put reader into ubuntu PC. If you don't have linux, oh well.
- Open Gparted.
- Gparted will show three partitions on the sd: a 270mb one, a 530 mb one, and a third huge one.
- run sudo dd if=/dev/(sdcardpartitionone) of=image.img and sudo dd if=/dev/(sdcardpartitiontwo) of=image2.img to make a backup (optional)
- Delete the 270mb partition in gparted.
- Run fsck on the 530mb partition and accept everything it wants.
- ???
- Profit!
