So I was wrong and obviosly, when I run batch file on windows

it gives me an error , iven if I made NO change to any patch file !!!

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.
