[Galaxy Note 3 Android Development] Roland_SGN:
Thx for the hint, but didn't help :( The SU has root access and double-checked the whole settings. Therefore I took a look in the system-log and found the following:

I opened a file-manager and found that the file /system/csc/feature.xml is there, but has size 0 bytes. :confused: Checking the file-permissions I see -600 ==> only the owner could read and write the file. So, I changed it to -666 and the above exception is gone. :cowboy: But unfortunately the save still not worx :( Reviewing again the logs I find another one

which I believe is due to zero-length-byte-size of the feature.xml. :(

So, on the one hand I am still not sure if this issue is related to the Omega-ROM. Perhaps a working feature.xml could help. ==>

Could someone post it here? So, I could test it.

[If there is the strong guess, to ask in another thread please tell me. I really have no idea, how this is related with Omeage9.0 especially since the feature.xml is NOT included in the ROM-file.]
