Why won't Lollipop install after I downloaded it?

Problem after downloading Lollipop update, it won't install (Nexus 5)

Hi,

I just received a notification to update my rooted Nexus 5 to Lollipop. It downloaded the 440 megabytes and prompted for a reboot.

But it didn't rebooted. Instead, I got a menu from Team Project with some options. I just hit the "reboot" button and it rebooted to Android 4.4.4. Look like I have lost the lollipop update??! When I go back to check for an update, it says my device is up to date.

Why the Team Project menu showed??! What should I have done? Why the update is lost?

thanks for your time and help

If you are completely stock (no changes to the system partition), just download the OTA zip file from google, save it to your phone's storage, reboot into TWRP, and install the OTA zip file you just saved.

To go from KTU84P to LRX21O , use this http://android.clients.google.com/p...ed-hammerhead-LRX21O-from-KTU84P.c1a33561.zip

If you are not completely stock, it is likely that you cannot take OTA (depending on what system file you changed)

Thanks for the reply. Using Nexus Root Toolkit, I reinstalled the stock recovery partition, then, it worked. The update applied and everything's fine now.
