Same question for the brightness fine control patch.

Those patches were lost in the major changes that happened between firmware version 3.19 and 4.0. I've had a good look for the brightness fine control patch without success, I wouldn't hold out any hope for that patch unless someone else can find it. I haven't looked so hard for the system/non system fonts patches yet though.

It won't do any good to try the patches from earlier firmware versions, they will just result in an error when the patching script runs.

Do any of the patches change the book cover size when in collections view?

The collections view is exactly the same as the main library view. The difference is in how the books have been filtered. If you can change one, then the other will change as well.

`Increase The Books Cover Size In The Library` The patch is in the file nickel.patch.

Here is the `Brightness fine control` patch for firmware 4.2.8283, paste into libnickel.so.1.0.0.patch:

Spoiler:

<Patch>
patch_name = `Brightness fine control`
patch_enable = `yes`
#
## Sun symbols change the frontlight brightness in 1% instead of 5% steps.
#
# ValueDisplaySlider::setStep(5) --> ValueDisplaySlider::setStep(1)
replace_int = 73AD96, 5, 1
</Patch>

Hi Geoff,
Thank you very much. I´m glad, that this very useful Patch is back, I missed it a lot.
Runs perfectly under FW 4.2.8283 on Aura ONE.

Now the last modification, which is still absent on my ONE, is the screensaver-Mod.

Regards Peter

Yes that is normal for the Windows script, there are a few patches enabled by default and they will probably not be able to be applied if the wrong firmware version is used. (The Linux/Mac script will not even get that far as it will not unzip the firmware if it has the wrong version in the name.)

There are three versions that must match for success:
1. version of the firmware downloaded from Kobo, e.g. kobo-update-4.2.8283.zip
2. version of the patches, e.g. patch_kobo_4028283.zip
3. version of the firmware already on the device, e.g. 4.2.8232 shown in Settings > Device information

If 1. & 2. don't match then you will probably get an error when running the patch script as you discovered, although in some cases there might be no error and a KoboRoot.tgz file will be created, depending on which patches were selected. This could happen if only multi-version patches were selected.

If 3. doesn't match 1. & 2. then the KoboRoot.tgz file might be greated without errors but it will be the wrong version for the device and that usually means the patched device won't boot and a factory reset will be required.
