Problem with updating from cm-12-20150228-NIGHTLY-taoshan

I've installed the cm-12-20150228-NIGHTLY-taoshan to my C2105 and now I want to update to cm-12-20150303-NIGHTLY-taoshan but I get this error.

This package is for device: C2105, C2104, c2105, c2104, taoshan this device is .

What can I do to solve this problem?

Same problem is with the cm-12-20150301-NIGHTLY-taoshan and also with downgrading to the cm-11-20140827-NIGHTLY-taoshan (which I had previously installed). It seems to me that the information about my device is missing. How can I add the information that this device is C2105/taoshan?

I've tried to get some information from my /system/build.prop file but it looks like the C2105 identifier is OK. Is it possible to turn off the device validation during new CM installation? This is what my current /system/build.prop looks like:

EDIT so I checked the "updater-script" file and it seems that the CM installer is trying to validate the property ro.product.device which is missing in my build.prop. So I've added it to the build.prop file and tried to install the CM again but... Still the same error!

I also tried to modify the build.prop and remove the validation but now I get error that the package is not valid because of checksum or something like that (I don't remember exactly)
