I used Wugs 1.6.2 root toolkit to root(4.2.1). I installed the 4.2.2 update and lost root. I also seemed to have lost any recovery. Quick boot was working before update. Now nothing. I have tried rerooting using the same toolkit. But I get a message saying ADB device was found but is offline. I had real problems installing the drivers initially on my Windows 8 notebook. What is the correct procedure for rerooting? and tips to get my drivers installed again/properly.
