A patch to prevent the AndroidBookLoadTablet_Aspect.parsed cover image file being downloaded or generated, which fixes a problem with the cover image for kepubs not being displayed on the book details screen if wifi is turned off.
(Note that recent versions of Calibre will copy the AndroidBookLoadTablet_Aspect.parsed image along wth other cover images if you have "Send covers" enabled, so this patch may no longer be needed.)

Spoiler:

<Patch>
patch_name = `Avoid generating/downloading redundant cover image`
patch_enable = `yes`
replace_string = 1104FA4, `AndroidBookLoadTablet_Aspect`, `N3_LIBRARY_FULL`

Block WiFi firmware upgrade: This patch should prevent the firmware being upgraded during WiFi sync. You can still upgrade by sideloading the new firmware or by syncing via the Kobo desktop program. See this thread for discussion.

patch_enable = `no`
replace_string = 1106BE1, `%3/%4/%5`, `k/99.9/5`
