I'm at post 19 reading thread.

This is the patch I was talking about: Block WiFi firmware upgrade, inside libnickel.

Description below:

Spoiler:

WARNING! THIS IS A DANGEROUS PATCH! READ THE INFORMATION BELOW CAREFULLY!

THIS PATCH IS UNTESTED, as there is no way to be sure it still works until
the next firmware version is released. If it works then the firmware will
not be upgraded during a WiFi sync, but you will still be able to upgrade
manually or by syncing with the Kobo desktop.

THIS PATCH COULD RESULT IN A BOOT LOOP when signing out of your Kobo account
(Settings > Accounts > Sign out) or when invoking a factory reset from the
device information menu (Settings > Device information > Factory reset).
REMOVE THIS PATCH BEFORE USING EITHER OF THOSE OPTIONS.
A factory reset invoked using the hardware methods (such as holding down the
light button while switching on) should not be affected.
