I bought a L90 from amazon (Tmobile) and the phone updated to lollipop

So when this phone came it was running android jelly bean which ran perfectly, had no problems, i saw that there was a update for lollipop so i went ahead and installed it and now phone is stuck in boot loop, black screen>lg logo>black screen>lo logo

sometimes i get lucky and phone actually boots up but 99.9% of the time after reboot its suck in that loop

any way i can fix this? i was thinking about going back to jelly bean stock but idk how. i might just return it.
