Instructions for patching firmware 4.20.14622

This patch thread is for firmware 4.20.14622 (8bb853a72a7c209047baedb2ef5b3c38eebf45e5):

Instructions for patching on Windows, Linux, or macOS with kobopatch:
  1. Download the Kobo firmware release
    You can find the download links here here.
  2. Download and extract the patch zip
    Download and unzip kobopatch_4.20.14622.zip from here.
  3. Copy the firmware file to the src folder
    Copy the original firmware you just downloaded into the kobopatch src folder.
  4. Install the firmware if needed
    Install the firmware on your kobo BEFORE proceeding with the next steps. You can do this by extracting the contents of the firmware zip into the .kobo folder and ejecting.
  5. Choose your patches from the files in the src folder
    Enable patches in the files in the src folder (or use the overrides in kobopatch.yaml to keep your options separate).
  6. Run kobopatch
    Double-click kobopatch.bat on Windows, or run ./kobopatch.sh on Linux or macOS. On macOS, you can drag it into the terminal and press enter (you may need to go to System Preferences - Security and Privacy - General to confirm that you actually want to run it).
  7. Install the patches by copying KoboRoot.tgz into the .kobo folder of your device
    If the patching succeeded, a file named KoboRoot.tgz will be created in the out folder. Copy it to the .kobo folder of your device. Safely remove your device once you are finished. On Linux, you may have to press Ctrl+H to show the .kobo folder.

I'm still not very comfortable with kobopatch and my very first update didn't go well. Do you see in the attached log what the problem is?

Yes. It's the "Hide all games" patch I made for you for the last version. Here's an updated one:
Code:
Hide all games:
  - Enabled: no
  - FindZlib: "#boggleContainer[devModeOn=false][qApp_deviceIsStorm=true]"
  - ReplaceZlib: {Find: "[devModeOn=false][qApp_deviceIsStorm=true]", Replace: ""} # games are hidden on storm, so make it apply to everything
Also, thanks for actually attaching a log rather than posting a small snippet or not even posting one at all!

Wow! This is great and fast personal patch! Much appreciated. Could this patch also work with a Kobo Aura? (I don't have it on hand to test)

Will the original 4.20.14601 sickel patch work or do we need a new one?

Thank you everyone who worked on the patches.

I seem to be missing something about dictionaries on version 4.20. I found the GitHub discussion where it was said that micthtml patching is no longer needed, and that naming custom dictionaries dicthtml and marking them read-only would bypass sync. That's what I did (I'm using Windows 10), but syncing always overrides my dictionaries? Any pointers?

As always, a big thanks to all those who labour to bring out the patches to us.

On the "Dictionary text font-family/font-size/line-height" patch by jackie_w

I like patching the firmware. But my ability is just changing 'no' to 'yes.
I want to use jackie_w's dictiionary patch. I want to decrease line height and font size. (I'm okay for now with font family). What exactly do i change?

For example, i see
Code:
  # Un-comment and edit next line to change font-size
  #- ReplaceString: {Offset: 15, Find: "%1px", Replace: "32px", MustMatchLength: yes}
I know how to "uncomment" (remove the # symbol). But what edits must i make? Do i change the number 15? or just 32px to, say "20px"?

Also, for
Code:
  # Un-comment and edit next line to change line spacing
  #- ReplaceString: {Offset: 34, Find: "1.40em", Replace: "1.30em", MustMatchLength: yes}
What must i change? Do I keep the 34 offset as is? Or should I change the number 34 to some other number? Should I change 1.30em to some smaller number, or is 1.30em already a smaller number relative to the 1.40em?

Thanks.


Code:
Dictionary text font-family/font-size/line-height:
  - Enabled: yes
  - Description: |
      This patch allows you to to customise the appearance of the text 
      in the pop-up and full-screen dictionary widgets.
      4.17.13651: improved to also reduce the blank lines displayed in many 
                  sideloaded custom dictionaries which contain <blockquote>.
      .
      See https://www.mobileread.com/forums/showpost.php?p=3521137&postcount=48
      for screenshots
      .
      You can change one or more of the following properties:
      - font-family
      - font-size
      - line-height
      .
      These are the Kobo defaults
                Glo - Georgia  23px  1.4em
                H2O - Georgia  29px  1.4em
              GloHD - Georgia  32px  1.4em
            AuraONE - Georgia  42px  1.4em
  #
  # Stage 1: Change DictionaryView to remove %variables
  # from:
  #    * { font: %1px %2; line-height: 1.4em; }
  #    div.descriptionFont { font-family: %3; }
  #    ol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; }
  #    ol p { font-size: %1px; font-weight:normal; }
  # to:
  #    * { font-size: %1px; line-height: 1.40em;font-family: Georgia                       ;}
  #    ol {margin-left:1em; margin-top:0}
  #    blockquote {margin:0.3em 0 0.3em 1em} blockquote>blockquote {margin:-0.3em 0 0 2em}
  #
  # ##### N.B. Do not change the next 4 lines #####
  - FindReplaceString:
      Find:    "* { font: %1px %2; line-height: 1.4em; }\ndiv.descriptionFont { font-family: %3; }\nol { font-size: %1px; font-weight: bold; margin-left: %4em; margin-top: 0px; }\nol p { font-size: %1px; font-weight:normal; }\n"
      Replace: "* { font-size: %1px; line-height: 1.40em;font-family: Georgia                       ;}\n\nol {margin-left:1em; margin-top:0}\nblockquote {margin:0.3em 0 0.3em 1em} blockquote>blockquote {margin:-0.3em 0 0 2em}\n"
      MustMatchLength: yes
  # ##### N.B. Do not change anything above this line #####
  #
  # Stage 2: N.B. You MUST keep old and new strings EXACTLY the same length
  #
  # Notes for changing font-family:
  #   1.  Pad the shorter of the old/new strings with spaces to 
  #       keep same length for both strings (see examples below)
  #
  #   2.  If the new font-family name (max. 29 chars) contains any spaces it 
  #       should be wrapped in 'single quotes' (see examples 2, 3)
  #
  #   3.  To change from Georgia to the Kobo default sans-serif font, Avenir, 
  #       use either one of the following to achieve the same result:
  #       - sans-serif
  #       - 'Avenir Next Medium'
  # 
  # Un-comment ONE ONLY of the following ReplaceString examples 
  #   to change dictionary font-family from default Georgia:
  #     - to a different built-in font
  #     - to one of your sideloaded custom fonts
  #
  #- ReplaceString: {Offset: 54, Find: "Georgia   ", Replace: "sans-serif", MustMatchLength: yes}
  #- ReplaceString: {Offset: 54, Find: "Georgia    ", Replace: "'Gill Sans'", MustMatchLength: yes}
  #- ReplaceString: {Offset: 54, Find: "Georgia      ", Replace: "'Kobo Nickel'", MustMatchLength: yes}
  #- ReplaceString: {Offset: 54, Find: "Georgia ", Replace: "Bookerly", MustMatchLength: yes}
  #
  # Un-comment and edit next line to change font-size
  #- ReplaceString: {Offset: 15, Find: "%1px", Replace: "32px", MustMatchLength: yes}
  #
  # Un-comment and edit next line to change line spacing
  #- ReplaceString: {Offset: 34, Find: "1.40em", Replace: "1.30em", MustMatchLength: yes}

Un-comment as required then customise by changing ONLY the value for "Replace". Do not change any "Offset" or "Find" values.

Regarding line spacing ... 1.40em is the default, a smaller number will display the dictionary definition lines closer together.

You must keep each "Replace" value exactly the same length as the "Find" value.

what did I do wrong?

The .bat file aborts just as it opens the nickel file (which I annex as a .txt file). I have read and reread what I have done to it, checking with a printout I have of the 4.18.13737 version, which worked ever since, and can't see where I went wrong. Can anybody help me?
Many thanks.
