My Nexus 5 phone has been updating for over 4 hours to the new marshmallow update stuck on the "installing system update screen" what do i do?

I found this, worth a shot:

After 30 minutes, I lost patience, so I did the press-and-hold the Power button for a few seconds. The Google reboot screen showed up, and it continued with the “Installing System Update” loop but only for one cycle! After it completed the one cycle, it automatically rebooted the device with the four circle animation (red, blue, yellow, green).

After about half a minute, happy times! The customary message “Android is Upgrading” appeared with the “Optimizing App X out of Y” progressing. And now the device is up and running again.

Did that work, Jo-Ellen Ellis ?

Welcome to Android Central! Something clearly went wrong. Force a shutdown by pressing and holding Power for about 15-20 seconds. Then boot into Recovery and wipe the cache partition: http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html. Reboot after that, and see if it boots up normally. If so, try the update again.

I got stuck here as well. I went into recovery and cleared the cache (which took about 30 minutes). After that, i rebooted, and am still stuck here in the same place as before. What else can i try?
