Optimizing App boot loop?

Tried updating from 5.02 to 5.1 using wugfresh nexus tool kit. (which I have used with all previous updates 4.4-5.0, 5.0-5.01, 5.01-5.02 and has worked great) I was rooted so I flashed the system image (like I usually do then re root...)via toolkit. Update finished without errors. Phone rebooted and went into "updating apps" mode, finished then rebooted and went into "Optimizing Apps" routine. All seemed fine. After all apps are optimized the phone appears to reboot and repeats the same optimzation. Every time once finished optimizing apps, the phone repeats.

I can boot into recovery or bootloader still but I want to know what Is the best solution to fix this so I don't further mess up my device(if that's even possible)

Same problem for me on both Samsung tab 2 7.0 and my nexus 5 both running 5.1 roms.

I had the same issue. Flashing also boot.img solved the issue.
After that it is recommended to clear cache.
