[thp1017]

for those who are interested, search in library by default for 3.1.0:

<Patch>
patch_name = `Search in Library by default`
patch_enable = `yes`
replace_bytes = 9E7BBC, 7E F7 9A E3, 00 46 00 46
replace_bytes = 9E7C08, 7E F7 74 E3, 00 46 00 46
</Patch>

Does anyone have the new settings to adjust the brightness of 1% by 1% for firmware 3.1.0? thank you

Give the following a try. It works on my Aura HD.

<Patch>
patch_name = `Brightness fine control`
patch_enable = `yes`
replace_int = 90DD08, 10, 01
replace_int = 90DD38, 10, 01
</Patch>

@DNSB or GeoffR,

Would either of you be able to figure out the 3.1.0 settings for the patch `Freedom to advanced fonts control`? I think there's a few of us font fanatics who like to have 'TypeGenius' for all fonts.

If it's a lot of work, I can understand if you're not keen ... we'll have to keep our fingers crossed for Metazoa.

I had a look at that patch, but it redirects a subroutine call through what seems to be a link-time jump table, and I don't know enough about how the linker works to figure out the new address to use.

The patches I have worked out all involve either blocking a subroutine call altogether (by replacing the branch instruction with a no-op) or changing the arguments that are passed to a subroutine.

Well I had another look and I realised that I didn't need to work out where the subroutine that the patch redirects finally ends up, I just needed to find another place in the code that calls the same subroutine and copy its call address.

So here is the advanced fonts control patch for 3.1.0 (d1b2f00933), I haven't tested it because the only fonts I have sideloaded are the ones from old firmware versions which already work with the advanced controls, so if you try it, post to confirm whether it works.

Spoiler:

I'm pleased to say it seems to work fine. Karma to you, sir.

Hi everyone! Please can someone explain me how to prepare the patch for 3.1.0?
With Metazoa's patch i have not problems, but i don't know how to do with new fw.
For example, i cannot find the file libnickel of my firmware, and which kpg file do i have to use?
Forgive my inability, thanks

You need three things to prepare the patch:

1. kpg.exe -- get this from a recent Patcher archive.

2. libnickel.so.1.0.0 -- get this from the firmware archive for your device on the first page of the Direct Links to Kobo Firmware thread. Inside the kobo-update-3.1.0.zip archive is another archive KoboRoot.tgz. Inside KoboRoot.tgz is the file usr/local/Kobo/libnickel.so.1.0.0 that you need.

3. kpg.conf -- Create this yourself using the patches for the new firmware posted in this thread. DNSB posted an example with most of the patches for 3.1.0 here: https://www.mobileread.com/forums/sho...&postcount=539

Put them all together in a directory and run kpg.exe as normal.

The code block covers the current state of the 3.1.0 patches. Copy and paste the contents into a kpg.conf file and use the kpg.exe file from Metazoa's v11 patcher. If you are using Windows, I'd recommend using 7Zip to extract the libnickel.so.1.0.0 file from the firmware archive.

Thank you very much, GeoffR and DNSB!



However, do you think that Metazoa will release a new patch?

[icallaci]

This is the first time I have patched my Kobo Aura HD (FW 3.1.0) and it worked flawlessly. Thanks to everyone for their time and effort in putting these patches together.

I have one question: I am using the Decrease Footer patch and would like a little more space underneath the "Page x of y" footer, as it is too close to the bezel of my Aura HD. What value do I change to achieve this? And do I increase or decrease the value?

You can try increasing the height: 25px value 5 pixels at a time to see how it looks for you.

So replace:
 `* {\n\theight: 25px;\n\tfont-size: 20px;\n}\n\n`
with
 `* {\n\theight: 30px;\n\tfont-size: 20px;\n}\n\n`

Hopefully, this works as a starting point.

David

Hmmm...changing theight doesn't seem to have any effect at all. Started with 30 and went up to 50 without seeing any noticeable difference. I guess I'll live with it for now, but if anyone figures out how to get just a little more space beneath the "Page x of y" footer, I'd appreciate it. Thanks for trying, David.

Edit: I saw a post somewhere that said to bring up the font menu and then turn the page to reset the footer a little higher on the page, but that didn't work for me either.

Try changing the end part from

`* {\n\theight: 30px;\n\tfont-size: 25px;\n}\n\n`

to

`ReadingFooter {\n\tmin-height: 50px;\n\tmax-height: 50px;\n\tqproperty-footerMargin: 20;\n}\n\n* {\n\tfont-size: 26px;\n}\n\n[localeName="ja_JP"] {\n\tfont-family: A-OTF Gothic MB101 Pr6N;\n}`

The Footer height can be increased/decreased by changing the two 50px values. The size of the 'Page x of y text' can be inc/dec by changing the font-size: 26px value.

That was probably me. It is relevant when using the ReadingFooter suggestion above.
