[Q] URGENT Please help.
I was using my rooted nexus 4 with bootloader locked and stock recovery and my phone notified me that I was due for a system update, even though I was already running Android 4.3. I thought this may be a supersmall release with minor bugfixes as the file was only 1.8MB. I pressed restart and install and the phone restarted and showed an Android lying down with a exclamation mark on top, like you see in recovery, except it said "error" beneath the Android. The phone restarted in about 10 seconds and said "Android is Upgrading. Optimizing apps 1 of 88" and so on.
It is working normally now and not prompting to update, but I want to un-root bcuz I am not enjoying root and I want to flash the factory image of Android 4.3. Please help me unroot, solve this problem and uninstall busybox
