Firstly, for the space problem, how many books do you have? And what type? Is that 9GB of epub or comics or something else? And how much space are you using in the main memory? How big is the database.

The reason for asking is that the device records information about the books in a database. This is in the main memory. If that runs out of space, then there will be problems writing the database to the disk. And if you do a sync and there are books to download, they will be put on the SD card. And the firmware update needs about 90MB of space to download. The device is supposed to manage this. For example, when I deliberately reduced the free space to about 50MB, it wouldn't download an update.

The types of books are important to the size of the database. An epub with a lot of chapters, will use more space. A kepub version of the same book uses even more. A CBZ uses a lot less as it doesn't have a lot of the metadata. And the ratio of database space used by a CBZ to the book size is a lot less than that for a kepub or epub.

For the time taken to do a factory reset, I'm not sure. I haven't done one for a while. Is there a difference between having the SD card inserted and not? And the device shows various steps. From memory, there is a resetting step, a restoring step, then it restarts and shows the dancing boxes before starting the setup process. That includes updating the firmware. Did you notice if any of the steps was particularly longer than before?
