Instructions for patching on Windows, Linux, or macOS with kobopatch:

1. Download kobopatch_4.10.11655.zip from here.
2. Download the firmware from here to the src folder.
3. Install the firmware on your kobo BEFORE proceeding with the next steps.
4. Enable patches in the files in the src folder (or use the overrides in kobopatch.yaml to keep your options separate).
5. Run kobopatch.bat on Windows, or kobopatch.sh on Linux.
6. 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.

I just tried to patch my KA2v1 (upgraded with currently unsupported 4.10.11655) using this patch method.

It worked great , but I think some text clarifications are needed for the not so bold casual user (See the red additions)

6. Enable patches in the *.yaml files in the kobopatch src folder (or use the overrides in kobopatch.yaml to keep your options separate).
7. Run kobopatch.bat on Windows, or kobopatch.sh on Linux.
8. If the patching succeeded, (see log file in the out folder) a file named KoboRoot.tgz will be created in the out folder. Copy it to the .kobo folder of your device.
9. Safe disconnect your device.

Just my 2cts.
Keep up the good work

@geek1011: Thank you for providing us with new patches. Meanwhile I know how to deal with the new system and I like it a lot, corse it saves a lot of time, making use of kobopatch.yaml. Your work is highly appreciated.

Should be

Ok, I see. I thought you only meant to replace the first one, and I didn't test the sickel patch.

I've tested it again. No errors.

No, as in on the kobo itself. Does it work when you actually open a PDF?

[jcn363]

Sorry.
My first time with PDF.
I don't really know what must test, but I don't see any widget.
Good luck.

The patch for the current firmware does not work on my reader (Kobo Aura H2O Edition 2 v1).
The KoboRoot.tgz is generated without any problems.

I have not changed anything in the yaml files in the src folder except for a few parameters. The activation of the individual patches is done by the kobopatch.yaml.

After installation on my reader it is not possible to open eBooks. As soon as I try, the reader restarts automatically. I tried this with several eBooks.

A factory reset also had no effect.

Anyone got any tips for me?

My changes to the kobopatch.yaml:
