Is there a kobopatch 4.41.23145 zip?

Uncle Robin · 11-17-2024, 05:50 AM

I've decided to gift my wife a Libra Colour as an update on her Libra H2O, as she's expressed an interest in having a colur ereader before. I plan to set it up for her completely so that when she gets home from work on the day it arrives, it's all ready for her to start using. But I can't find kobopatch 4.41.23145.zip anywhere to patch it. Am I correct in assuming that doing a global find and replace of 4.38.23171 with 4.41.23145 will do the job? Especially in kobopatch.yaml which I now know to be the key yaml to update?

Do exactly that. But, be prepared for some of the patches to not apply.

If you post in the firmware thread which patches do not apply, someone may be able to help.

Thanks, will do.

As mentioned in the title, some patches from firmware 4.40.23081 don't work in firmware 4.41.23145

Code:

libadobe.so.yaml:
Remove PDF map widget shown during panning

libnickel.so.1.0.0.yaml:
My 24 line spacing values
Set KePub hyphenation
Hide browser from beta features
Customize ComfortLight settings
Replace adobe page numbers toggle with invert screen
Remove line from bottom tab bar

src/nickel.yaml:
Customise Header back button
Remove forgot pin button from lock screen
Custom page navigation scrubber
Increase size of kepub chapter progress chart

src/librmsdk.so.1.0.0.yaml:
Default ePub serif font (Amasis)
Default ePub sans-serif font (Gill Sans)

Note:
- Using Kobo update Firmware 4.41.23145 for Kobo Clara BW
- Ref patches 4.40.23081: https://www.mobileread.com/forums/sh...&postcount=188
- Kobo removed Amasis and Gill Sans font in Kobo Libra Colour, Clara Colour, and Clara BW.
- ## in kobopatch.yaml indicates the patch doesn't work

I made some nickel.yaml & librmsdk.so.1.0.0.yaml GitHub commits back in April for fw 4.39.22801. @geek1011 hasn't made a full patch release since so I'm posting the patch updates here.

Patch updates for src/nickel.yaml These 4 patch updates should work OK in all of fw 4.41.xxxxx, 4.40.xxxxx, 4.39.xxxxx

Custom header/footer captions:
  - Enabled: no
  - Description: |
        This patch allows you to change various header/footer caption attributes:
        - font-family (Part 1)
        - font-size & vertical position fine-tuning (Part 2)
        - width (Part 3)
        Header & footer will automatically be a matched pair.

        fw 4.23.15505 No longer possible to customise font-size for GloHD/ClaraHD
            separately from AuraHD/H2O.
        fw 4.29.18730 No longer possible to style header/footer separately.
        fw 4.32.19501 Kobo's major changes to font handling mean that ability to customise
            font-family in a kobopatch is now very limited.

Default ePub sans-serif font:
- Enabled: no
- Description: |
This patch changes the default ePub sans-serif font to 'Noto Sans'.
If the book's stylesheet specifies the generic 'font-family:sans-serif;' then
the ePub reader will try to use the built-in GUI system sans-serif font
('Avenir Next' or 'Rakuten Sans').
This patch allows you to change the default to a different sans-serif font
(built-in or sideloaded).
N.B. This patch does not affect kepubs.

# fw 4.32.19501: The font-family name in Replace: must now be the WHOLE name
# not just the first few characters of the name.
# fw 4.34.20097: Kobo removed the 'Gill Sans' font files from the firmware. There is
# no longer a built-in sans-serif font with a name short enough to use in this patch.
# You can still use the patch with one of your sideloaded sans-serif fonts.
# fw 4.34+: Kobo continue to revise the list of built-in fonts included in the firmware.
#
# To use a different font, change "Noto%20Sans" in each Replace: string
# to another font name (14 characters max).
# For example, change "Noto%20Sans" to "Trebuchet" to use a sideloaded Trebuchet font.
# The 3-char string, %20, represents a single space in the font-family name.
#
# If your new font name is longer than 14 chars you would need to:
# - Use a font editor to shorten the internal font-family name to <= 14 chars
# - Rename the 4 font filenames to match the new shortened name
# - Copy the 4 renamed font files into the Kobo sideloaded fonts folder
- FindReplaceString: {Find: "/normal/Rakuten%20Sans", Replace: "/normal/Noto%20Sans"}

My wife's Libra Colour arrived today, and as far as I can tell, all the patches I'd enabled are active on her now-patched device.

Is the kobopatch GitHub dead?

Aleron Ives · 11-19-2024, 08:00 PM

No. Kobo made major firmware changes with the release of the Clara BW/Colour and Libra Colour, and since the kobopatch contributors don't get paid for their work, they'll get around to updating the official repository whenever they have the time and energy to do so.

Thank you! I just moved from Kindle and trying to understand the state of Kobo community.

Aleron Ives · 11-20-2024, 02:33 AM

The release of new devices makes updating the patches much more difficult than for routine firmware updates for existing devices, so there's a lot more work to be done than usual. You can find some of the offsets that need updating for various patches spread across various forum threads, but they're not in the repo yet.

I see.
I was able to assemble the patches I need for 4.40 from those different messages across the forum. But I’m still missing hyphenation patch for 4.41.

Do you know if there is a documentation of the process of how to find required offsets in the first place? Or maybe thread about patch development process?

I'm afraid I can't help with any patches missing from libnickel.so.1.0.0.yaml. I *think* they may need decompile skills, which I don't have.

I've never used the 'Set KePub hyphenation'. If you're a calibre user can't you use the hyphenation options in the KoboTouchExtended driver to control kepub hyphenation?

I've decided to gift my wife a Libra Colour as an update on her Libra H2O, as she's expressed an interest in having a colur ereader before. I plan to set it up for her completely so that when she gets home from work on the day it arrives, it's all ready for her to start using. But I can't find kobopatch 4.41.23145.zip anywhere to patch it. Am I correct in assuming that doing a global find and replace of 4.38.23171 with 4.41.23145 will do the job? Especially in kobopatch.yaml which I now know to be the key yaml to update?

Aleron Ives Wizard Posts: 1,588 Karma: 16300090 Join Date: Sep 2022 Device: Kobo Libra 2	The release of new devices makes updating the patches much more difficult than for routine firmware updates for existing devices, so there's a lot more work to be done than usual. You can find some of the offsets that need updating for various patches spread across various forum threads, but they're not in the repo yet.
