You need to be on the firmware version the patch applies to. What you need to do is to download the firmware and the patch file following the instructions in the first message in that message thread. You will find the Cyrillic keyboard patch in the libnickel.so.1.0.0.yaml file in the src directory. Simply change the no after enabled to yes.
Please note that I do not know if this patch will work for 4.33.19611 but I think that it should.
- Download the firmware file
- Download the patch file.
- Unzip the patch file which will create several files and directories
- Copy the firmware .zip file into the src directory. Do not unzip it.
- Take a look at the .yaml files in the src directory. Enable those patches in those .yaml files you want to try. I suggest doing one or two to start.
- Run the kobopatch.bat (for Windows) or the kobopatch.sh (Linux or MacOSX). Don't forget the ./ before the filename for Linux or MacOSX.
- If successful, this will leave a KoboRoot.tgz and a log.txt file in the out directory. Copy the KoboRoot.tgz file to the .kobo directory on your Kobo, safely eject it and it should reboot and install the patches.
- If not successful, there are two options. The error was so early in the process, the log.txt file was not written. Generally, an indicator of a tying error in a .yaml file. If the error occurred later, the log.txt file will indicate where the error occurred.
I've attached an image of what you should see in the src directory.
Good luck!
