Thank you again for your effort.
I installed the patch following your instructions and everything went fine.
Just a little question: in the kpg.conf for previous firmware 3.0.0 I found two patches named `Ignore book internal CSS stylesheet` and `Ignore book TOC navpoints`

Spoiler:

<Patch>
patch_name = `Ignore book internal CSS stylesheet`
patch_enable = `no`
replace_string = 1438104, `s`, `_`
replace_string = 143811C, `s`, `_`
</Patch>

<Patch>
patch_name = `Ignore book TOC navpoints`
patch_enable = `yes`
replace_string = 143A5C4, `n`, `_`
</Patch>

It is possible to have these also for firmware 3.1.1?
