Patches for Firmware 4.45.23684

4.45.23684 is for the Libra Colour, Clara BW, and Clara Colour.

This thread is for the patches for the new firmware 4.45.23684. 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.

Running 4.45.23684 on Libra Colour. Applied "Remove recommendations (row1col2)" via kobopatch-webui, patch applied cleanly but the "Need something to read? Shop Kobo" tile on the home screen is still visible. Is this tile actually row1col2 on the Libra Colour, or is it a different widget? Already have hide_home_row3 working via NickelMenu experimental.

Patches for Firmware 4.45.23684

Follow the instructions and was able to see the nickel menu initially. Tested by launching KO reader and noticed once exited KO reader, nickel menu is missing. Reinstall KFmon from here https://www.mobileread.com/forums/sh...d.php?t=314220 but was still unable to see nickel menu. What am I doing wrong? On latest firmware 4.45.23684 Kobo Libar Colour obviously.

What has this to do with the patches?

My sincere apologies it have been a long while since I have needed to do any patching for this firmware version and I have assumed a special patch is needed for this firmware version. I now see that it's an independent issue.

I have no idea what I'm doing but I reverse-engineered a fix for the "Both page turn buttons go next" patch that seems to be working on my Libra Colour-

Code:
Both page turn buttons go next:
  - Enabled: no
  - Description: Make both page turn buttons on the Libra Colour go next in the reader.
  - ReplaceBytes:
      Base:          "ReadingView::keyPressEvent(QKeyEvent*)"
      Offset: 60
      Find:    [0x68, 0xB9]
      Replace: [0x0D, 0xE0]
