i think thats the easiest way to root is that if you have rooted 562 then do the OTA (over the air) then you will keep root also

Talking
Worked for me. I had a lot of errors after flashing the old kernel btw. But after rooting with the one click program I flashed back the new kernal.sin and loader.sin and now I don't get any errors anymore. I removed all bloatware and ads using root ^^
