Issues patching 4.38.23429 - Page 3

rogerinnyc · 10-05-2025, 08:50 AM

Can someone give me a quick primer on how to apply this fix? I downloaded the rebuilt kobopatch.exe and substituted it in for the kobopatch-windows.exe file in the /bin folder of the patch. I tried both without changing the name to match and with its original name. When I try to run the kobopatch.bat file it just immediately closes and I don't get a new .tgz file.

Obviously I'm doing something wrong, but can someone steer me in the right direction?

Thanks!

EDIT: OK, fixed it with two steps -- renamed the new file to "koboptch-windows.exe" -- i.e., without the "a" of patch (which is what the .bat file is looking for when executed); and turned off my controlled folder access security setting in Windows 11, which was blocking running of the new .exe

EDIT2: Works beautifully -- each of the both buttons and both taps turn page forward now work. Thank you!!

libnickel.so.1.0.0.yaml

FeatureSettings - BookSpecificStats
I've never used this patch but the following works if you manually edit the Kobo conf file.

Code:

[FeatureSettings]
BookSpecificStats=true

FeatureSettings - ShowFacebookShare
I've never used Facebook, but maybe it has a similar workaround to the one above.

Allow rotation on all devices
Once again, a manual edit of the Kobo conf file works on my Clara2E.

Code:

[DeveloperSettings]
ForceAllowLandscape=true

I can't help with the next 4 as they're also in my 'not working' list. It may be the presence of the FindInstBLX/SymPLT combo as raised earlier by @AsherMaximum

My 24 line spacing values
My 10 line spacing values
Unify font sizes
Don't uppercase header/footer text and change page number text

I don't use them but these 2 also use the FindInstBLX/SymPLT combo.

Set KePub hyphenation
Replace adobe page numbers toggle with invert screen

I thought recommended advice for InvertScreen has, for a long time, been to do it via the NickelMenu option rather than this patch. That's what I've been doing for ages.

nickel.yaml (i.e. not librmsdk.so.1.0.0.yaml as per your post)

Increase size of kepub chapter progress chart
Try this hex location:

Code:

  - BaseAddress: 0x19A1644 # qss/ReadingMenuStatsView.qss

Hi Jackie,

Thank you for fixing Increase size of kepub chapter progress chart patch.
I wonder if you manage to fix Increase size of kepub chapter progress chart Audiobook patch?

thanks

I tried your new offset and it did not throw up and error. Thank you.

Change the offset as posted by @jackie_w. That does not throw up an error. Also use the new koboptch.exe linked from post #26 in this thread. Also, rename it to koboptch-windows.exe. It goes in the bin directory and replaces what's there.

I don't think patching the audiobook chapter progress chart has ever been included in the "official" nickel.yaml, has it? However, the following 2-part patch can be used to change both barcharts in a single patch.

Notes:

This new patch is a replacement for the original Increase size of kepub chapter progress chart in nickel.yaml.
An extra benefit is that, with luck, it should survive firmware updates better because it no longer needs a new BaseAddress for every firmware.
If you normally use your own custom values for height/width of #chapterSizes, then you'll need to change them in both parts, i.e. Part 1 for kepubs, Part 2 for audiobooks.
Should work in both v4.38.23429 and v4.43.23418 (and probably many earlier firmware versions).
Those who never read audiobooks on their Kobo can use this patch without issue.

Thanks a lot, the patch runs perfectly.

I've applied all of those patches except Custom header/footer page number text and they apply. I've not applied that one. Try it and see if it applies or not.

I tried the Custom header/footer page number text, and it works but you may need to disable Don't uppercase header/footer text patch

What you can use instead is Don't uppercase header/footer text and change page number text That incorporates both patches in one. That works.

Sorry, I didn't mention which Kobo I use, but it's the Aura One. Are the answers still valid? Thanks.

Yes, the answers are valid for the same firmware version. The device matters not.

I updated the firmware to the latest version. I'd like to apply the patches, but I can't find the file I usually use, such as kobopatch_4.38.23171.zip. Where can I find it? Thanks.

Here is an unofficial copy of the 4.38.23429 patches. It is WINDOWS ONLY as only the Windows version of koboptch-windows.exe has been updated to work with this firmware.

Unfortunately, you won't find that file since the last official kobopatch file was kobopatch_4.38.21908. https://pgaskin.net/kobopatch-patches/.

You can use the older kobopatch zip file, extract it, and add the latest Kobo firmware in the SRC folder.

Modify the first two lines in Kobopatch.yaml as below:
Code:
```
version: 4.38.23429
in: src/kobo-update-4.38.23429.zip
```

Follow the post #26 in this thread regarding koboptch.exe

Note: you may need to see the old threads for the kobopatch version after 4.38.21908 (4.38.2308 and 4.38.23171 if you are using the older Kobo model). There are fixes for some patches that don't work.
