5.0 update not received Hi guys I searched alot but not found any thing related to this. So if anyone tell me what's the reason for this.

I just purchased Google nexus 5 and upgraded from 4.4.2 to 4.4.4 and now waiting for 5.0 update on my device. But It has been over a month that I didn't received any updates and where others guys have received 5.0.1 as well. So anyone having same issue or something wrong with my device.

Thanks in advance
You could just wait it out, as you will eventually be prompted, or you have a couple of options.

You could try and speed up the update by trying to trigger it again, try wiping google play services data (it worked on my nexus 4).

Or you could flash the system image

A better option however would be to just flash the ota file, which can be done without unlocking your bootloader.

Get the ota, and follow the instructions at this link:
