it'll not affect your CID, this RUU should work with your CID in my opinion.. otherwise it'll just give you an error before installation.
I flashed with RUU 1.28.401.7, then OTA update 1.29.401.12 appeared, which I installed. Now it shows the new 4.2.2 OTA update 2.24.401.1, but why it does not OTA update with X.X.X.16, as my stock rom? should I now install my Nandroid backup to get the X.X.X.16?
