Anyone tried HC-kTool v1.25? It's compatible with G variant. You can go save
your Efs folder in the most easiest way!! kTool also have the ability to dump
kernel of your current firmware. I'm still on DZKI1, so anyone on DZKJ2
dumped the kernel? Mind to share ........

That is the stock 2.3.6 = DZKJ2 from
Samseng 
. Either you're on 2.3.5 or 2.3.6 you can root (+CWM).
