I came across a guide on XDA forum to bypass screen lock. I'm connected to my work's Exchange server to retrieve emails and once I setup account - they automatically required me to use num-lock screen. Very annoying since I have to use it every single time I turn screen on. The command was very easy, "adb shell rm /data/system/gesture.key". When I run it I get "permission denied". From what I read, it has nothing to do with rooted/unrooted but rather with OEM giving access to adb shell. Has anybody been able to run such command? or have any insight about it or how to gain access to it?
