So, I added the following at the end of the Geoffr's libnickel.so.1.0.0 file
Spoiler:
<Patch>
patch_name = `New home screen footer rename`
patch_enable = `yes`
#

#
#
# The lenght of the replace string must be 25 for example:
# ` ` - replace with space show as empty
# `FirstName LastName `
# `If lost call:123456789012`
#
find_base_address = `Find your next great read`
replace_string = 0000, `Find your next great read`, `Version 4.4.9349 `
#
#replace_string = 0000, `Find your next great read`, ` `
#replace_string = 0000, `Find your next great read`, `FirstName LastName `
#replace_string = 0000, `Find your next great read`, `If lost call:123456789012`
#
#
# The lenght of the replace string must be 11 char.

find_base_address = `)\0BROWSE KOBO\0`
replace_string = 0002, `BROWSE KOBO`, `patched `
</Patch>
