I've a big problem...
My nexus 5 configuration: TWRP recovery - Root privileges - Android 4.2.2
The smartphone notified me the availability of Android 4.3.3. I accepted and the package has been downloaded. The phone has rebooted, but there was no trace of the installation. The phone is divided into TWRP recovery.
I rebooted the system from recovery. The system is still Android 4.2.2 and tells me that the system is updated. In fact he says "last update check xx.xx" (where xx.xx is the hour).
Do you have suggestions on how to proceed?
You're my only hope!!
