Instructions for patching firmware 3.16.0

Thank you..so it seems I have a less responding epub reader,and a fast responding kepub reader with a non removable kepub header which can be taken away with the showPageHeader but then only the title is gone,it still consumes the same space,and it can't display PNG files properly anymore, with every update Kobo manage to introduce a new bug that cripple the reader more and more
And then we don't count the fact that without your patches it would be even a less device,because I will not even bother the update if you don't release the patches..
(did Kobo ever give an explanation/reason why it leaves such big gaps at the bottom of the reader while unpatched ?)
Sometimes I feel like i am involved at a hobby project,not a serious company that try to make a decent reader.

I've added the missing `Fix kepub side bearing font cut-off bug` patch to the attachment in post #1, and included it below so you can paste it into your current libnickel.so.1.0.0.patch file:

Spoiler:

<Patch>
patch_name = `Fix kepub side bearing font cut-off bug`
patch_enable = `no`
# Multi-version patch: 3.16.0 - 3.16.0+
#
# In kepubs, characters with large side bearing values (such as italic f, J) can
# be cut off if they appear at the very end of a line. The problem occurs in
# normal reading mode when the margin adjustment slider is set to minimum and
# in full-screen mode at any margin slider setting. To fix it this patch adds
# one of the following lines to the built-in kepub stylesheet, depending on
# patch options chosen (first line is the default if no options are changed):
#
#  body>div{padding-left:.2em!important;padding-right: .2em!important}
#  body>div{padding-top: .2em!important;padding-bottom:.2em!important}
#  body>div{padding:     .2em                          .2em!important}
#  body>*  {padding-left:.2em!important;padding-right: .2em!important}
#  body>*  {padding-top: .2em!important;padding-bottom:.2em!important}
#  body>*  {padding:     .2em                          .2em!important}
#
# There are two main types of kepub, each affected differently by this patch:
#
# Type 1: kepubs created by Kobo from epub2 books, or created by Calibre with
#         a recent version of the KoboTouchExtended driver.
#
# Type 2: kepubs created by Kobo from epub3 books, or created by Calibre with
#         an old version of the KoboTouchExtended driver.
#
# Type 1 kepubs work best with this patch, the only side effects should be
# slightly larger screen margins. Some Type 2 kepubs might suffer additional
# side effects such as extra horizontal or vertical space between elements.
# There is an option below (marked **1**) where you can choose whether to
# fix the bug only for Type 1 kepubs (default) or for both types.
#
# There are also options below (marked **2**) to make the patch suit kepubs
# with horizontal or vertical text directions, or both. The side effects for
# Type 2 kepubs will likely be worse if the option for both horizontal and
# vertical is chosen.

</Patch>

The patch has changed a little but I think it will work just as well. (The new patch employs the body>div selector instead of the div#book-columns selector to save some space.)

[outlandos]

Before starting:

1. Make sure your Kobo ereader is already running firmware version 3.16.0 (f56b42a2e1).

2. Check that your battery is well charged.

3. Note that in Windows 8 the instructions below might require the batch file to be run in admistrator mode.

I think you mean 3.15.0, or am I wrong?

Anyhow, I followed all the steps carefully and when I unplugged my Glo HD it started updating, but now I see 5 blocks getting black and white in the middle of the screen for as long as 10 straight minutes, does updating always takes this long or should I get worried?

Edit; oh shit, I actually think you did not make a typo there, and this topic is for patching 3.16.0...... I am stupid. Did i brick my device permantly now?

The instructions and patches in this thread are for firmware 3.16.0 only. If you have applied them to a device that is running firmware 3.15.0 then you might have to do a factory reset.

Edit: There is a procedure for doing a manual factory reset for the Glo HD here. There might be other methods too.

[Nick_1964]

Is the search in library by default still possible ? (not meaning to rush you Geoffr ? )

Thank you, factory reset worked.

Now I have 3.16.0 installed, it was way easier than i thought!

I've updated the attachment in post #1 to include the missing `Search in library by default` patch, and include it here for those who want to paste it into their current libnickel.so.1.0.0.patch file:

Spoiler:

<Patch>
patch_name = `Search in Library by default`
patch_enable = `yes`
# SearchEditBox.setSearchType(0) --> SearchEditBox.setSearchType(1)
replace_bytes = 9025D4, 41 46, 01 21
</Patch>

There are now 5 search location options available when you tap the search bar: Bookstore, Library, Current Read, Annotations, and Dictionary. Which one comes up by default depends on where you were when you invoked search.

The patch should cause Library to be the default whenever Bookstore would have been the default without the patch, but have no effect if another location is the default. I.e. if you invoke search from within a book it should still default to Current Read.

I was waiting for this ! thanks a lot

[Ripplinger]

One I was watching for daily as well, thank you very much!

[Gabriel.Voyager]

The last version of the patch on my Kobo Glo HD, with the `Search in Library by default` and `Fix kepub side bearing font cut-off bug` activated is perfect.
Thank you!

Do you have installed the 3.16 on your Aura H2O?
If yes, which Mark? The Mark 6?

Thank you!

I did it on my H2O with mark4 KoboRoot only, following the advice of davidfor here. No problem till now.

Kobo aura HD, Mark 4 KoboRoot.tgz + patches. Works like a charm, here also.
But i cant make on change that i would like to: I cant chande inital font size from 12 to 18. I could really use some help:

# Start with this font size: (GloHD, Others)
replace_int = 87B38E, 14, 14
replace_int = 87B392, 12, 18

Is this the line that should look like this? or i'm doing something wrong?
