At first, I also dont want to use CSSU because -ve thinking that it'll break something. But after reading so much about CSSU, I decide to update thru CSSU because I know that I can trust this community. Somemore, I know there's no support from Nokian anymore. So we must help and trust each other. Thanks to community and dev for your contribution For who, still not update to CSSU, its your choice but I think this in only way to keep our device alive...
