When I did the factory reset, it didn't just wipe my configuration, it actually restored the old original OS version (4.0.7523 in this case). That's weird! It must save a copy of the original firmware version on the sdcard somewhere.

If you look at the internal uSD card, you'll notice that there are two Linux partitions, one of which, going by memory, is labelled Recovery.

There's something wrong with this process or the kobo-update-4.18.13737.zip file I downloaded. I did download it twice and compared sha256s and they were the same.
Either some intermediate upgrade is required or the upgrade is broken. The system was as factory-reset as I know how to make it and it still failed the upgrade.

Interesting. Which version of the kobo-update-4.18.13737.zip file did you download remembering that the Aura 2 comes in two versions which require different firmware downloads (if the 7th character of the serial number is a 2, you need the mark 7 firmware otherwise you need the mark 6 firmware). If I documented it correctly:
Code:
the mark 6 update file had a SHA256 of:
FE351E7830A7740A95905700660CEB72F0792E264D35996C52AF636E21530AB1
while the mark 7 update file had a SHA256 of:
4372EA6C038F9452CA1B034FAD40CC904189086C55F48A66EA83C0762B37A8BE
I will admit to getting a chuckle out of your privacy beliefs. Basically, when I'm feeling paranoid, I connect to WiFi at a local hotspot, register with a throwaway email address since Kobo does not appear to do any checking (imapseudonym@erehwon.net is an example). Once that's done, turn off wifi, disable the automatic sync and forget about it.
