Instructions for patching firmware 4.3.8966

[GeoffR]

See the Firmware 4.3.8966 spotted discussion thread for information about what has changed in this firmware version.

See the Index to the Metazoa firmware patches thread for a description of what some of these patches do.


Before starting:

1. Make sure your Kobo ereader is already running firmware version 4.3.8966 (9c8144b8c0). If not, then you need to upgrade before applying this patch.

2. Check that your battery is well charged.


Patching from Windows, Linux (i386/x86_64), or Mac (OS X 10.8-10.9, i386/x86_64):

1. Download and extract patch_kobo_4038966.zip (attached).

2. Download the Kobo firmware archive version 4.3.8966 for your device (See this thread) and copy it into the 4.3.8966_source/ subdirectory. (Don't unzip the firmware.)

3. Read and edit all the *.patch files in the 4.3.8966_source/ subdirectory in order to: choose which patches to enable (patch_enable=`yes`) or disable (patch_enable=`no`); and to change some of the replacement values to suit your device and preferences.

4. In Windows double-click 4.3.8966.bat; For Linux/Mac open a terminal, change to the patch_kobo_4038966/ subdirectory, and run ./4.3.8966.sh from the command line.

5. If there were no errors, copy the resulting KoboRoot.tgz from the 4.3.8966_target/ subdirectory to the .kobo directory on your ereader.

6. Safely eject and unplug the device, which will then update and restart.


To return your ereader to its original unpatched state:

1. Edit all the 4.3.8966_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).

2. Repeat steps 4-6 of the procedure above.


Note that the following patches are enabled by default:

`Fix page breaks bug`
`Default ePub monospace font (Courier)`
`Custom left & right margins`
`Custom page refresh options`
`Fix three KePub fullScreenReading bugs`

[GeoffR]

Notes:

Be extra careful checking the version number of the firmware your device is running. There have been a lot of different 4.3 versions released, and the version number on the device must match exactly with the version number used for patching.


Other patches:

`Dictionary pop-up, prevent cut-off of left-edge text`

`Force user line spacing in KePubs (more forceful version)`


If anyone has other patches for firmware 4.3.8966, post them in this thread and I'll add a link to this post.

Thank you very much for quickly set the patcher. It works fine on all our Kobo-Reader (H2O, Glo HD, Glo).

Thank you for your work!!!

Thanks again for the quick work on the patches especially with the recent firmware of the day release schedule.

For anyone interested in fixing the minor annoyance where the left edge of the dictionary pop-up text is cut-off (see images in this post), here's a new patch:

It's for the libnickel.so.1.0.0.patch file.

Spoiler:

<Patch>
patch_name = `Dictionary pop-up, prevent cut-off of left-edge text`
patch_enable = `yes`
# Multi-version patch: 4.3.8871 - 4.3.8966+
#
# DictionaryView increase ol padding
#     ol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; padding-left: 1.1em; }
# --> ol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; padding-left: 1.4em; }
#
find_base_address = `ol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; padding-left: 1.1em; }`
replace_string = 005B, `1.1em`, `1.4em`
</Patch>

Notes:

• Although this patch should be OK on all devices, on a KA1 the cut-off problem is hardly visible, so KA1 users may not want to bother.
  
• Testing was done using H2O, GloHD and KA1

Thank you so much!

@ GeoffR.... Any chance you can add the option of turning said new menu on or off?

Have never seen it here.

Regards

You need to look a bit harder, Jack See libnickel.so.1.0.0.patch

patch_name = `Disable new home screen`
patch_name = `Enable new home screen`

Thank you very much, Geoff!

Hi everyone,

i just applied both of the line spacing patches (only one at a time) but after my A1 reboots i can't change the spacing.
Without the patches it works, but i prefer smaller spaces between the lines.
With a patch applied, i can pull the slider to left and right and nothing happens.
Has anyone else having problems with this?

[dmapr]

Are you trying on the same book as without the patches? Some books CSS will set the line height preventing the patch from taking effect.

[oren64]

You have this two patches.

libnickel.so.1.0.0.patch
`Force user line spacing in KePubs`
`Force user line spacing in ePubs (part 1 of 2)`

librmsdk.so.1.0.0.patch
`Force user line spacing in ePubs (Part 2 of 2)`

[the_Pan]

@dmapr - good point, i will try it with another one

@oren64 -
I meant the libnickel patches "my 10 line spacing values" & "my 24 lines spacing values" at the beginning of this patchfile.

Does this happen in ePub or KePub books, or both? What other patches do you have enabled?

The only thing I can think of that would cause the line spacing slider to stop working is if you had just one part of the following two-part patch enabled without enabling the other part:

`Force user line spacing in ePubs (part 1 of 2)` (in libnickel.so.1.0.0.patch)
`Force user line spacing in ePubs (part 2 of 2)` (in librmsdk.so.1.0.0.patch)
