Patches for Firmware 4.45.23697

[JSWolf]

4.45.23697 is for the Libra Colour, Clara BW, and Clara Colour.

This thread is for the patches for the new firmware 4.45.23697. 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 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.

P.S. xor_ has added some new patches. Please see the 2nd post for more information

Good morning! I am on 4.45.23697 and really want these two, especially the first one (both page turn buttons next). Is there another patch or method that works to get this back again? Cheers.

Not that anyone knows or they would already be fixed/updated. So you'll have to do without. Sorry.

Got it. Appreciate the work you do.

Happy to help.

These are the equivalent patches re: buttons forward and swipe gestures for fw. 4.45.23697. I can't actually test them because I don't have a reader with that firmware but I would think they should work the same.
Would be nice if somebody could verify.

#both buttons forward
both buttons forward anchored:
  - Enabled: yes
  - BaseAddress: {Sym: "_ZN11ReadingView13keyPressEventEP9QKeyEvent"}
  - ReplaceBytes:
      Offset: 0x3C
      FindH:  68 B9
      ReplaceH: 0D E0

#disable fw/bw swipe gestures
disable fw/bw swipe gestures:
  - Enabled: yes
  - BaseAddress: {Sym: "_ZN11ReadingView12processSwipeEP12SwipeGesture"}
  - ReplaceBytes:
      Offset: 0xE8
      FindH: FA F6 3C CE 
      ReplaceH: 00 BF 00 BF
  - ReplaceBytes:
      Offset: 0xF6
      FindH: F7 F6 A8 CA 
      ReplaceH: 00 BF 00 BF

#disable menu swipe gestures
disable menu swipe gestures:
  - Enabled: yes
  - BaseAddress: {Sym: "_ZN11ReadingView12processSwipeEP12SwipeGesture"}
  - ReplaceBytes:
      Offset: 0x134
      FindH: 1D F7 D2 C8 
      ReplaceH: 00 BF 00 BF
  - ReplaceBytes:
      Offset: 0x13c
      FindH: EF F6 68 CC 
      ReplaceH: 00 BF 00 BF

@xor_, I'll add in these patches and if anyone does apply them, they can say if they work or not.

JSWolf, is there an updated step by step guide on how to apply individual patches from scratch as a newbie to this? I tried looking at the links here but some of them are dead by now. I want to try that next button patch without the WebGUI as you suggested.

It's not difficult at all if you're comfortable with basic copy/pasting.

The patches go into the file libnickel.so.1.0.0.yaml in the src subdirectory of kobopatch. Just paste them in there at the end. If you're only interested in the buttons patch, you can just paste this:

#both buttons forward
both buttons forward anchored:
  - Enabled: yes
  - BaseAddress: {Sym: "_ZN11ReadingView13keyPressEventEP9QKeyEvent"}
  - ReplaceBytes:
      Offset: 0x3C
      FindH:  68 B9
      ReplaceH: 0D E0

Save the modified file, run kobopatch, and it should just work.
Just be sure not to change anything of the code. Kobopatch is sensitive to formatting, additional space characters, doesn't like tabs, etc..

I can't test it on this specific firmware because I don't have such a device. I know the patches apply correctly because I can see that in kobopatch. The only thing I cannot verify is what it does on the the actual device. But that doesn't mean there's any real danger. Worst thing to happen is that it doesn't work. Then you can go back to the stock firmware. But I'm confident that it will work.

[JSWolf]

The patches have been updated. Two new patches and one fixed. These are not yet tested. They do apply. So if anyone applies these patches and tests them, please post if they work or not.

New patches...

• Disable forward/backward swipe Gestures
• Disable menu swipe gesture

Fixed patches (confirmed to work)...

• Both page turn buttons go next

• Load the file kobopatch.yaml into a text editor.
• Look for the lines that start with src/ under Overrides:.
• Under each different src is the name of the file the patches are in.
• Load that file into a text editor
• Now in kobopatch.yaml, you'll see the patches listed with the name of the patch and a no after. Change the no to Yes to enable that patch. Using the src yaml file, you may see a more detailed description of what the patches do.
• When you are done, double click the .bat file if you are on Windows.
• The file KoboRoot.tgz will be in the out directory and you then load that onto your Kobo in .kobo directory and it will install.
• You will see above patches that are known not to work ##Does not work So don't enable any of those.

I am all patched. Thank you JSWolf for the quick update, and xor_ for sorting out which is for me the absolutely essential patch. And Jackie_w and everyone for all the time and effort involved. You are all appreciated.

I can happily confirm that both buttons go next works on this firmware.

I'm sorry I may have been unclear, the actual links under Usage don't really work or reflect any updates - you and others here may be familiar with it but this is all my first time so I was looking for a really basic guide. When I go to that page:

Step 1 says "Download the zip for your firmware version from here." but that links to a Sep 2023 release, is that the latest? Even the main releases subdir doesnt have anything newer.

Step 2 says "Download the firmware from here " but the 'here' link points to a 404/not found

I am pretty handy with all this stuff and git generally but as it is my very first time patching I dont want to screw anything up or brick anything, hence my newbie-level questioning. Thanks for tips.

Oh man now I see the readme INSIDE the kobo patches zip!!! D'oh - thats exactly what I was looking for! My apologies for being dense, I had thought the zip was strictly patches.
