No still No,
If you do like this, you have to add one more step
Flash CF root LA6 to upgrade kernel, as during updating ROM(LA6), you have to 'keep CF root' that won't update kernel.
So I recommend this
- Flash Factorysys.KJ1.tar with PC Odin, at end U will have KJ1 ROM + Root
- Download
this (P.S. here zImage file is already added), extract on PC, run already rooted, connect device(USB debugging, unknown sources shud be enable), it will flash CF root kernel LA6. At end U will have KJ1 ROM + Root + CF root kernel LA6 + CWM
- Flash LA6 ROM with CWM, N select 'keep CF root' when asked.
So at end of this you will have latest ROM + Kernel + Root+CWM
