I also follow the N9QTweak thread, and in the past I had Open Mode Kernel for NITdroid. Many people, like me, when installing, for example, two or more tweaks or sub-tweaks at the same time, after the first, the second or randomly, the system close N9QTweak (with installation in progress, interrupted) and goes to home screen.. The same happened, randomly, with installation of apps: in a first time it seems that is installing, but randomly the installation crash and goes to desktop with apps not installed.. The above is common to all that have open Mode kernel.
