What the external variant does is roughly:

- kill nickel
- 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.

@frostschutz tested and still incredible on 22th sept. 2019 ! thanks

For macos users' sake, could you please upload a tgz file ? when unzipping the zip file in the Finder, macos unpack everything without asking thus there is no tgz to be seen... (the only way to do it and get the tgz file on a mac is to unzip with the terminal)

Just wanna say thank you so much for this, I made a backup of a factory image Kobo Glo HD image, updated it to 3.19.5761 (so that it doesn't fail to gather updates) with the resize mod in .kobo, so it takes the empty space as soon as I flash it back.

It's perfect.

That's a good idea. The only problem is that factory reset is a quickish way to solve some problems. If you do one, it will restore the factory firmware and you are back to needing to manually install 3.19.x.

The internal SD to internal SD transfer probably won't work on the Mini (and other pre-Aura-HD devices with only 256MB RAM). That one relies on copying all files into RAM to allow you replacing the internal card on the fly, but it just needs plenty of RAM for that...

For older Kobos with external microsd slot you can use the Magic Memory external variant. But I think the Mini doesn't have external microsd slot either?

So at most you could clone the card using a PC, then resize the data partition with the Magic Memory resize variant.
