Patches for Firmware 4.38.23648

[JSWolf]

Firmware 4.38.23648 is for the Libra 2.

This thread is for the patches for the new firmware 4.38.23648. Most of the patches work. It may work for later firmware. I cannot say as I've not tried.

All of the patchers have been updated thanks to @geek1011

I would like to thank @aardvark for the original updated Windows .exe, geek1011 for fixing all of patchers and @jackie-w and @Semwize for help in updating some of the patches.

Use the file kobopatch.yaml to override the no to yes for each patch you want to apply. I cannot say all the patches work. Most of them do apply. If you have any issue with any of the patches, just post about the issue.

This is the same format as the unofficial patches for 4.38.23171.

There are more patchers if you need a different one not in the ZIP file. Please go to https://github.com/pgaskin/kobopatch...es/tag/v0.16.0 to see if what you need is there if it's not in the ZIP file.

Thank you to @jackie_w for fixing even more patches.

Please note:
Old patch name Increase size of kepub chapter progress chart
has been updated to Increase size of kepub/audio chapter progress chart so that:

• chapter progress barcharts for both kepub and audiobooks can be similarly enlarged. Users who never read audiobooks can still use the new one without issue.
• this patch is no longer reliant on a constantly-changing BaseAddress hex offset so should survive further firmware upgrades without needing to be updated every time.

The update nickel.yaml is now included in the ZIP for the patches.

Thanks to @jackie_w, nickel.yaml has been updated and fixes some patches that previously did not work as well as jackie_w Screensaver full in the custom yaml and Remove forgot pin button from lock screen.

Patches that are known to not work will be posted here.

The following patches do not work

• Both page turn buttons go next
• Customize ComfortLight settings
• Remove PDF map widget shown during panning

If any others do not work, please post about them.

You can use the following code to make patch Remove forgot pin button from lock screen (nickel.yaml) work in fw 4.38.23648:

Remove forgot pin button from lock screen:
  - Enabled: no
  - Description: |
      Removes the Forgot PIN -> Sign Out button from the lock screen.
      If this is enabled and you forget your pin, you will need to
      hard reset your Kobo.
  - BaseAddress: 0x19ADBB4 # qss/PinCodeInputDialog.qss
  #- BaseAddress: 0x19C11ED # qss/ParentalControlPinCodeVerifyView.qss
  - ReplaceZlib:
      Find: "#lblForgotPin[qApp_deviceIsDragon=true],\n#lblSignOut[qApp_deviceIsDragon=true] {\n  font-size: 26px;\n}"
      Replace: "#lblForgotPin,#lblSignOut{qproperty-visible:false;}"

Please can you make the necessary change in the post #1 .zip? Thanks.

Thank You. I'll get to it tomorrow when I have the time.

Remove forgot pin button from lock screen has now been replaced and version 2 has been posted. Thanks much!

@jackie_w is it possible you could fix the patch Both page turn buttons go next?

Sorry, unfortunately not. I've no idea how to update any of those SYMPLT*-type patches in libnickel.so.1.0.0.yaml. It's possible it just needs the Offset value to be corrected, but I don't know how to do that either.

Oh well. Thanks!

I tried this with the previous fw patching Libra2
readelf output & finding those page turn fucntions:

 18279: 00f66a01   244 FUNC    GLOBAL DEFAULT   11 _ZN11ReadingView13keyPressEventEP9QKeyEvent
[...]
 28946: 00f66941    96 FUNC    GLOBAL DEFAULT   11 _ZN11ReadingView17prevPageWithTimerEv

Which would put the offset at 192 but still errors out when patching

It seems, that "Custom font sizes" patch does not work on my Libra 2. It applied on 4.38.23552 firmware.

How are you applying the patches? Are you using the file kobopatch.yaml to select which patches you want?

Is anyone else using the patches and the patch Custom font sizes have any trouble with it?

I do use it and it does work for me. I prefer the fine tuning and wider range of smaller font sizes.

[Aleron Ives]

Are you also using the 4.38.23552 firmware, though? I also use the patch, but I have firmware 4.35 on my Libra 2, so that isn't helpful for goligoski's problem.

Sorry, that was my mistake. After reverting back to 4.38.23552 the patch does exactly the same. I think I misremembered the patch having different granularity. It’s still not ideal for me, as there are many tiny and huge font sizes, but very few practical options for reading. One setting is smaller than I prefer, and the next one is slightly too big. It is better than the stock version though.

Can i edit the granuality in the patch, like it can be done for line spacing patch?

Yes. The patch is using ReplaceInt, so you can just edit the replacement values to your liking. There may be a limit to how many steps you're allowed to have, so if you want to increase the number of small sizes even further, you should probably reduce the number of large font options to match. You could also raise the minimum font size to be closer to the size you actually want, since the default minimum size is so tiny you'd practically need a magnifying glass to read it. This would free up extra steps for use in your target font size range.
