After rooted my nexus 4 I attempted to use "integrate update into system" function in link2sd on Chrome (I know I know it is kind of pointless to have link2sd in nexus 4).
Anyway, it didn't work. It is kind of expected since I never got this to work on any device running android 4 or later. In my experience before nexus 4 (and android 4.2), all I need to do after a failed app integration is to reboot the device and reinstall the update.
However on nexus 4, now whenever I reboot the device, Chrome will not run. Updating will not begin either. I will have to reboot it again, then the updating will start, then Chrome is fixed, till next time I need to reboot.
So anyone know what is wrong and is there a way to fix this (other than restore to a earlier backup)?
