but use cwm to flash insecure kernel, we must rooted the phone first...so is there any way to root the phone without increasing the counter??
Yes, if there are any other ways to root I9100G without flashing kernel, like using apps, but so far there is none.If you are afraid of increasing the counter, don't root now.
Or you can buy a USB jig to reset the counter.
