- umount user partition (other mods could prevent that from succeeding, which would be suboptimal)

- display a "progress bar" (same as nickel bootup bar, squares, going backwards)

- mount the filesystems read-only (of the internal card)
[progress bar would get stuck forever if this fails, e.g. possible if earlier umount failed]

At that point the preparation would be done, now comes the interaction part:

- show a black screen
- if external card is present, wait for it to be removed first

- show a white screen
- wait for external card to be inserted [this card will be formatted]

The removal/insertion is simply a means to confirm that you want this card to be formatted. It's to help avoid blindly formatting a card that was left inside the device.

After replacing the external card, user interaction phase has ended.

- display a "progress bar" (going forwards)
- partition and format the new card
- copy all data

this takes a while, depending on amount of data and card speeds.

- reboot the device

After reboot the device would complain about unable to read the external card (since it's formatted for internal use) however this didn't cause any damage when I tested it, so I opted to not have a 2nd interaction phase prompting you to remove the card first...
So what I did is I reset my device again as I tried without KSM and it did not help as when I logged into Kobo it updated to firmware 4.12.12111 which the script did not work under.

I reset it again and then I used sqlitebrowser to put in fake details so I can keep it at that version. After that the script ran under firmware 3.7 which was the recovery firmware version. So I can say now I have safely backed up my SD card if I will need it in the future again.

I thank you for this script. I can also confirm it does not work under 4.12.12111. I may have done something wrong but I do not believe so.
